    Simple bone cyst is an oft-described entity, which goes by many sobriquets and has been presented in the literature as early as 1926. It is a lesion of unclear etiology with many proposed hypothesis for its pathogenesis and nonspecific histopathological presentation. We present a case of a solitary bone cyst, which clinically presented as a solitary lesion, but radiological examination revealed multiple lesions peppering the maxilla and the mandible, thereby highlighting the importance of atypical presentation and “surprise” lesions that may show up on radiological examination.

    The simple bone cyst, as newly classified by WHO in 2005, is a lesion related to the jawbones. Therefore, it is not a cyst, since it is a cavity devoid of epithelial tissue. It is a rare pathology affecting the mandible more than the maxilla. Its onset occurs mainly during the first two decades of life, irrespective of sex. The purpose of our report is to exhibit the particular case of a 17-year-old male patient whose radiography showed an osteolytic lesion in his right mandibular body. Exploratory surgery and biopsy are performed showing a simple bone cyst. Since then, he is controlled through imaging studies, but presenting an atypical evolution, with its size increasing considerably within a 4-year follow-up. Key words:Case report, simple bone cyst, hemorrhagic bone cyst, solitary bone cyst, idiophatic bone cyst, mandible. PMID:24558539

    Simple bone cysts are well-defined intraosseous radiolucencies that often extend between the roots and appear clinically like empty cavities. This article aims to provide more information about this lesion with limited prominence in academic literature, to illustrate atypical cases, and to provide a review of the current literature. A series of six atypical cases of simple bone cysts is presented and their clinical, radiographic and microscopic characteristics, differential diagnosis, treatment and follow-up are discussed. Correct diagnosis of this entity is of key importance, since it presents with clinical & radiographic similarities to other bone lesions, some exhibiting more aggressive behaviour. PMID:23218982

    ABSTRACT Background The purpose of this report is to present a rare case of co-occurrence of florid cemento-osseous dysplasia with simple bone cyst in a middle aged Asian woman. Most of the reported cases are isolated cases of simple bone cyst or florid cemento-osseous dysplasia, but co-occurrence of these two entities is extremely rare. Methods The authors report a 41 year old female patient with co-occurrence of mandibular florid cemento-osseous dysplasia with simple bone cyst. A thorough clinical and radiological examination was carried out. Results It was diagnosed mandibular cyst with possible co-occurrence of florid cemento-osseous dysplasia. Surgical exploration of the multilocular lesion was applied. Since, the patient was symptomatic at the time of presentation utmost caution was taken during the surgical procedure as florid cemento-osseous dysplasia is associated with hypo-vascularity of the affected bone. Based on histopathological, as well as supporting clinico-radiological findings a confirmative diagnosis of florid cemento-osseous dysplasia co-occurring with simple bone cyst was made. Patient was followed-up for a period of six months and was reported to be asymptomatic. Conclusions Timely diagnosis and well planned treatment is important to obtain a good prognosis when a rare co-occurrence of two or more bone lesions affects the jaws. PMID:24421997

    Abstract Simple bone cysts (SBCs) are benign bone tumors. However, the treatment of SBCs remains controversial because of their healing rate and the invasiveness of surgery. The purpose of the present study was to evaluate the treatment of SBCs using a cannulated hydroxyapatite (HA) pin. A total of 43 patients (35 males, 8 females; mean age 12.1 years; age range, 5–22 years) with SBCs were treated with continuous decompression by inserting ceramic HA pins between 1989 and 2014. The SBCs were located in the calcaneus in 23, the humerus in 15, the femur in 3, and the pelvis in 2 cases. In all patients, minimal fenestration of the cyst wall and curettage and multiple drilling in the cyst wall were performed, followed by insertion of the HA pin. The mean follow-up period was 26.6 months. Operating time, healing period, risk factors for recurrence, and the cure rate were evaluated. Healing was achieved without intervention in 38 patients after a mean of 6.4 months. Two patients had persistent small residual cysts, which had no changes after 1 year at the latest follow-up. There were 5 patients with recurrences (humerus 4, femur 1), who were cured by curettage and artificial bone grafting. The final healing rate by cannulation only using an HA pin was 88.2%. On Fisher exact test, age, site of SBCs, and distance from the physis were found to be significantly associated with SBC recurrence (P < 0.05). In the present study, cannulation using an HA pin for SBCs was found to be a useful technique, particularly for calcaneal cysts, because it is a minimally invasive procedure with a high cure rate. In patients <10 years, involvement of the humerus and contact with the growth plate were significant risk factors for SBC recurrence. PMID:26107670

    Florid osseous dysplasia (FOD) has been described as a condition that typically affects the jaws of middle-aged women of African descent and usually presents as multiple radiopaque masses distributed throughout the jaws. The diagnosis is generally based on clinical and radiographic presentation, often involving various regions of the jaws without evident bone expansion. This article describes the course of FOD in a 27-year-old African-American woman during 22 years of follow-up, emphasizing the dynamic radiographic characteristics of this entity and unusual co-occurrence with multiple simple bone cysts. These data reinforce the importance of long-term follow-up in patients diagnosed with FOD. PMID:26943084

    Simple liver cysts of various sizes are present in 1% of the population. Most are found incidentally and require no treatment. However, in a few the cyst is symptomatic and requires surgery: celiotomy and unroofing of the cyst. A 64-year-old woman with a symptomatic, simple cyst of the liver underwent laparoscopic surgery. After an uneventful course she was discharged on the 3rd postoperative day. Simple liver cysts can be safely treated by laparoscopic surgery. PMID:8138207

  10. How simple are ‘simple renal cysts’?

    2014-01-01

    The increasing use of medical imaging as an investigative tool is leading to the incidental and frequent finding of renal cysts in the general population. The presence of a solitary or multiple renal cysts has been generally considered benign in the absence of a family history of renal cystic disease or evidence of chronic kidney disease. Nonetheless, a number of recent studies have questioned this consensus by reported associations with the development of hypertension or malignant change. For these reasons, some clinicians consider the presence of renal cysts to be a contraindication to kidney donation. The situation is complicated by the different usage of the term ‘simple’ by some radiologists (to indicate non-complex lesions) or nephrologists (to indicate age-related non-hereditary lesions). We propose that the term ‘simple’ be replaced with the morphological description, Stage I renal cyst (Bosniak Classification). The presence of a Stage I renal cyst should not preclude kidney donation. However, occult renal disease should be excluded and appropriate donor assessment performed. PMID:25165175

    Objective The purpose of this study was to review the clinical and radiographic features of solitary and COD-associated SBCs. Methods Archived imaging reports from the Special Procedures Clinic in Oral and Maxillofacial Radiology at the Faculty of Dentistry at the University of Toronto between 1 January 1989 and 31 December 2009 revealed 23 COD-associated SBCs and 68 solitary SBCs. Results Almost all solitary and COD-associated SBCs were found in the mandible. Furthermore, 87.0% of COD-associated SBCs were found in females in their fifth decade of life (P < 0.001) while solitary SBCs were found in equal numbers in both sexes in their second decade of life (P < 0.005). COD-associated SBCs were also more likely to cause thinning of the endosteal cortex, bone expansion and scalloping of the superior border between teeth (all P < 0.001) than solitary SBCs that are classically described as having these characteristics. Finally, COD-associated SBC demonstrated a loss of lamina dura more often (P < 0.05) than solitary SBCs. Conclusions Knowledge of the sporadic association between COD and SBC and their potential radiographic appearances should prevent inappropriate treatment and management of these patients.

    Forty-four patients with aneurysmal bone cysts were treated with curettage with or without bone grafting, and in 26 (59%) recurrence developed. Of 11 patients treated with radiation, in only 1 (9%) the disease was not controlled. In 1 patient, radiation-induced sarcoma developed. Since the introduction of cryosurgery 27 years ago, 51 patients have been treated with cryosurgery. The patients had an average age of 13 years (range, 2-32 years). Thirty-four primary aneurysmal bone cysts and 17 secondary aneurysmal bone cysts occurred in association with 7 giant-cell tumors, 5 chondroblastomas, 2 fibromyxomas, 2 nonossifying fibromas, and 1 unicameral bone cyst. The tumors were classified as inactive in 9 patients, active in 31, and aggressive in 11. Treatment consisted of local intralesional excision followed by application of liquid nitrogen. The defect was either allowed to heal spontaneously (n = 26) or was reconstructed using an intramedullary rod (n = 2), bone grafts (n = 5), fibular strut grafts (n = 14), or polymethylmethacrylate with Steinmann pins (n = 4). At median followup of 85 months (range, 24-311 months), the overall cure rate was 82%. This was increased to 96% after a second, or repeat, cryosurgery. The disease in all patients eventually was controlled by cryosurgery. The mean functional rating was 90% (range, 63%-100%). Intralesional excision with adjunctive cryosurgery is an effective method for the treatment of aneurysmal bone cyst. PMID:7634571

    An aneurysmal bone cyst (ABC) is a benign, locally proliferative vascular disorder of non-neoplastic osseous lesions in children and young adults. Seventy-five percent of ABCs occur before the age of 20 years. They comprise 1.4% of all primary bone tumors, and commonly occur in the long bones. Spinal ABCs are much rarer. We present to you one such rare case of ABC involving the lumbar spine which was successfully treated with surgery. The clinical pathological and radiological features are described. The treatment options available are discussed. PMID:26396610

    A three-year-old male Siberian Husky dog was referred to the Veterinary Teaching Hospital in Osaka Prefecture University with a complaint of difficulty in expelling the stools. By rectal examination, a mass as big as a fist could be detected occupying the cavum pelvis. Radiographically the mass had a thin bony shell bulging from the pubic periosteum. In the shell, radiolucent trabeculation gave the area a "soap bubble" appearance. The cut surface of the removed mass showed a honeycomb-like pattern constituted of some small loculate bony cysts. These cysts were separated from each other by a fibrous or bony trabeculae with blood-filled vascular channels or sponge-like structures. From clinical and pathological findings, this mass was diagnosed as a pelvic aneurysmal bone cyst. After surgery, the patient completely recovered without tenesmus. PMID:9409519

    Unicameral bone cysts (UBC) and aneurysmal bone cysts (ABC) are benign cystic lesions of bone which are easily diagnosed. However, unusual locations may lead to a false diagnosis. Therefore the aim of this retrospective study was to determine the frequency of unusual localizations. The authors studied 451 cases with histopathologically confirmed diagnosis of UBC or ABC, seen between 1981 and 2012. In the UBC group (352 cases) humerus, femur and calcaneus were found to be the most common sites, while acetabulum, scapula, scaphoid, lunatum, metacarpals, metatarsals, toe phalanges and ulna each accounted for less than 1%. In the ABC group (99 cases) the most common sites of involvement were femur, humerus and tibia, while finger phalanges, ilium, acetabulum, pubis, calcaneus, cuboid, and toe phalanges each accounted for only 1%. The differential diagnosis of cystic bone lesions should include both UBC and ABC. Pain complaints plead for the latter, except in case of fracture. PMID:26280957

    Aneurysmal bone cysts predominantly occur in young adults and the long bones, the lumbar spine and the pelvis are mainly affected. This article presents the case of a 22-year-old woman with the very rare localization of an aneurysmal bone cyst of the atlas and an atlas fracture after a minor trauma. The initial radiological diagnosis was a suspicted aneurysmal bone cyst which was confirmed histologically. Due to the unstable fracture it was decided to carry out surgical treatment with occipitocervical stabilization in combination with a transoral bone graft. After a period of 11 months the fracture had completely healed and the implants were removed without any complications. PMID:23887801

    This prospective study was performed with ultrasound (US) to determine the prevalence of unilocular, nonseptated adnexal cysts ("simple cysts") in healthy postmenopausal women and the relationship between cyst occurrence and both hormone replacement and length of time since onset of menopause. Transabdominal and transvaginal US were performed on 149 volunteers aged 50 years or older. Patients were classified according to hormone regimens (no hormones, unopposed estrogen, continuous daily estrogen and progesterone, and sequential estrogen and progesterone) and time since onset of menopause (less than 5 years, 5-10 years, and greater than 10 years). Simple adnexal cysts were found in 22 women with the aid of transvaginal and/or transabdominal US, yielding a relative frequency of 14.8% +/- 5.7% and a prevalence of 14,800 patients with cysts per 100,000 patients. No statistical relationship was found between cyst frequency and type of hormone replacement or length of time since onset of menopause. PMID:2052725

    Transabdominal and transvaginal ultrasound (US) examinations were performed in 184 asymptomatic postmenopausal volunteers to determine prospectively (a) the frequency and natural history of simple adnexal cysts in healthy postmenopausal women and (b) the relationship between cyst activity and both hormone replacement and length of time since menopause. Eighty-three simple adnexal cysts were found in 52 women. Thirty-two of 184 women (17%) had 37 cysts identified at initial examination; 46 new cysts appeared in 31 women (11 of whom previously had cysts). Forty-nine women with 72 cysts were reevaluated with subsequent US scanning over a period of 3-23 months. Thirty-eight of the 72 cysts (53%) disappeared completely, 20 (28%) remained constant in size, eight (11%) enlarged by 3 mm or more, two (3%) decreased in size by 3 mm or more, and four (6%) both increased and decreased in size on repeated examinations. No statistical relationship was found between presence of cysts or cyst activity with respect to the type of hormone replacement or length of time since menopause. PMID:1509047

    Objective To assess the efficacy of percutaneous unroofing (PU) for treating simple renal cysts, compared with laparoscopic decortication and open surgery. Patients and methods From November 2009 to October 2010, 11 patients with 12 simple cysts in renal units were managed by PU. All cysts were evaluated with ultrasonography and abdominal computed tomography. A standard transurethral resectoscope was used to resect the cyst wall, and the parenchymal portion of the cyst was subsequently cauterised. A drain was left in place for 2 days. Success was defined as a >50% reduction in cyst diameter. Results At the 5-month follow-up, patients were asked about their symptoms and assessed by ultrasonography. Of the 12 cyst units, eight were completely resolved, three were reduced to <50% in diameter and one was persistent, close to the original size. Conclusion Simple renal cysts can be managed safely by PU, with a success rate of >90%. This technique offers several advantages over open surgery, with a shorter hospital stay, improved convalescence and reduced risk of complications. PU also avoids the multiple trocar sites, extensive dissection, and technical difficulty associated with laparoscopy. PMID:26579308

    This report describes a case of a solitary unicameral patellar bone cyst in a young dog. A five-month-old, male Dobermann Pinscher dog was referred for a 10-day left hindlimb lameness. A mild swelling of the peripatellar soft tissues of the left patella was detected upon physical examination. Signs of pain were elicited upon direct palpation of the patella. Radiographic examination revealed an oval radiolucency within the medullary cavity at the base of the left patella. Radiographic examination, arthroscopy, and histopathology findings supported the diagnosis of a benign patellar bone cyst. The condition was treated by surgical curettage and autogenous bone graft harvested from the ipsilateral proximal tibia. Clinical signs, including lameness and signs of pain upon deep palpation, disappeared three weeks after surgery. Follow-up re-evaluation five years after surgery revealed no recurrence of the cyst and the patient was asymptomatic. PMID:26299878

    Aneurysmal bone cysts are rare benign lesions of bone tissue, infrequent in craneofacial skeleton with regard to other structures like long bones or the spine. They are composed of sinusoidal and vascular spaces blood-filled and surrounded by fibrous tissue septa. We present a case of a 29-year-old Caucasian male with a big swelling in the left mandible associated to pain and rapid growth. He referred previous extraction of the left inferior third molar. On the X-ray study, an expansive multilocular and high vascularized bony lesion within the mandibular angle was observed. It produced expansion and destruction of lingual and buccal cortex. An incisional biopsy was performed showing a fibrous tissue with blood-filled spaces lesion suggestive of an aneurysmal bone cyst. After selective embolization of the tumour, surgical resection was done with curettage and immediate reconstruction of the defect with an anterior iliac crest graft. Aneurysmal bone cysts are non-neoplastic but locally aggressive tumours with occasional rapid growth that may be differentiated from other multilocular process like ameloblastoma, ossifying fibroma, epithelial cyst, giant cell granuloma and sarcomas. Treatment of choice consists on conservative surgical excision of the mass with curettage or enucleation. When resection creates a big defect, primary surgical reconstruction is recommended.

    Intraosseous ganglion cysts are rare causes of wrist pain. Surgical treatment of this pathologic condition yields good results and a low recurrence rate. The main complications are joint stiffness and vascular disturbances of the lunate bone. Wrist arthroscopy is a surgical technique that reduces the intra-articular operative area and therefore minimizes postoperative stiffness. This article describes an arthroscopic technique used for lunate intraosseous cyst resection associated with an autologous bone graft in a series of cases to prevent joint stiffness while respecting the scapholunate ligament. This study was based on a series of 4 patients, all of whom had wrist pain because of intraosseous ganglion cysts. Arthrosynovial cyst resection, ganglion curettage, and bone grafting were performed arthroscopically. Pain had totally disappeared within 2 months after the operation in 100% of patients. The average hand grip strength was estimated at 100% compared with the opposite side, and articular ranges of motion were the same on both sides in 100% of cases. No complications were reported after surgery. On the basis of these results, arthroscopic treatment of intraosseous synovial ganglion cysts seems to be more efficient and helpful in overcoming the limitations of classic open surgery in terms of complications.

    The aims in treating patients diagnosed with critical-sized bone defects resulting from bone cysts are to replace the lost bone mass after its removal and to restore function. The standard treatment is autologous or allogeneic bone transplantation, notwithstanding the known consequences and risks due to possible bone infection, donor site morbidity, bleeding and nerve injury and possible undesirable immune reactions. Additionally, allogeneic grafts are inhomogeneous, with a mosaic of components with difficult-to-predict regenerative potential, because they consist of cancellous bone obtained from different bones from various cadavers. In the present study, a 22-year-old patient with a history of right humerus fracture due to bone cysts was diagnosed with recurrent cystic lesions based on X-ray results. The patient qualified for an experimental program, in which he was treated with the application of a bioresorbable polylactide hybrid sponge filled with autologous platelet-rich plasma. Computed tomography and magnetic resonance imaging performed 3, 6, and 36 months after surgery showed progressive ossification and bone formation inside the defect cavity in the humerus. Three years after treatment with the bone substitute, the patient is pain free, and the cystic lesions have not reoccurred. PMID:26704550

    Fetal ovarian cysts are the most frequent type of abdominal tumors in female fetuses with prenatal detection rate of more than 30%. The etiology of fetal ovarian cysts is unclear, but hormonal stimulation as well as presence of maternal diabetes, hypothyroidism, Rh iso-immune hemolytic disease and toxemia has been generally considered responsible for the disease. Complications of fetal ovarian cysts include compression of other viscera, cyst rupture, hemorrhage and, most frequently, ovarian torsion with consequent loss of the ovary. Management is controversial with several options described in the literature, including watchful expectancy, antenatal aspiration of simple cysts to prevent torsion and ovarian loss and finally, resection of all complex cysts in the neonatal period. To date, no case report has described recurrent complex cysts with rupture in the fetal period and recurrence of simple cyst in neonatal period. By presenting this case, we wanted to show that surgical intervention in case of prenatally diagnosed fetal ovarian cyst should be considered postnatally and only in symptomatic or complicated cases.

    The fibro osseous lesions of the jaws represent a diverse group of entities that are characterized by replacement of normal bone by a fibrous connective tissue matrix, with in which varying amounts of osteoid, immature and mature bone and in some instances, cementum like material are deposited. Fibro osseous lesions of the jaws include developmental (hamartomatous) lesions, reactive or dysplastic processes and neoplasms. Juvenile ossifying fibroma (JOF) is a unique fibro osseous neoplasm. It has 2 histopathological variants (1) Trabecular juvenile ossifying fibroma (TrJOF) and (2) Psammomatoid juvenile ossifying fibroma (PsJOF) with TrJOF affecting the jaws of children. Only 20% of the patients are over 15 years of age. JOF is more common in maxilla than mandible. Origin in extragnathic locations is extremely rare. It presents as an asymptomatic progressive, rapid expansion of jaws. Radiographically, tumour is well circumscribed, along with lack of continuity with adjacent bone, cortical expansion & perforation. Histopathologically it consists of a cell rich fibrous stroma with bundles of cellular osteoid and bone trabeculae without osteoblastic rimming, and aggregates of giant cells. It has a recurrence rate of 30-58%. Long standing lesions shows cystic changes. Aneurysmal bone cyst is the most common complication. Here we present a case report of 16 yr old female patient with clinical, radiographic & histopathological features of Trabecular JOF with Aneurysmal bone cyst. PMID:25478458

    Aneurysmal bone cysts (ABCs) rarely occur in the cranial bone. Surgical resection can lead to bone defects, deformities, functional abnormalities, and so on. This article describes a frontal ABC in a 73-year-old man who has a rapidly increasing swelling in the frontal bone preceded by an accidental trauma. In this case, we use percutaneous sclerotherapy with absolute alcohol under the guidance of fluoroscopy to treat the ABC instead of traditional surgical resection. When analyzed the follow-up imaging, bone reconstruction happened after using absolute alcohol. It is a feasible alternative treatment for ABC arising from the cranial bone. PMID:25668118

    The aneurysmal bone cyst (ABC) is a fast-growing tumor of undefined neoplastic nature. It is occasionally an aggressive benign lesion whose treatment of choice is a complete resection, even though the risk of profuse transoperative bleeding exists. We present a female patient with thoracic spine deformity, with progressive paresthesias and muscle weakness of lower extremities that evolved to paralysis of both lower extremities and sphincter incontinence. Based on radiographic films, lytic lesions were identified at T7 to T9 vertebrae as well as medullary space invasion. In electrophysiologic tests, a complete somatosensorial pathway block was reported. Prior to resection of the neoplastic lesion and thoracolumbar stabilization, an incisional biopsy was performed. There was no postoperative medullary functional improvement. Morphological findings corresponded to an aneurysmal bone cyst at T8. This lesion is mainly located in the long bones and less frequently of the spine, where instability and medullary compression may occur. It is possible to confuse this neoplasia with other lesions. Hence, definite diagnosis with biopsy is necessary for determining an adequate therapeutic plan to eradicate recurrence risk or associated neurologic sequelae, as well as to gain proper stability at the involved vertebral segments.

    Aneurysmal bone cysts are benign bone tumors that usually present in childhood and early adulthood. They usually manifest as expansile osteolytic lesions with a varying potential to be locally aggressive. Since their first description in 1942, a variety of treatment methods has been proposed. Traditionally, these tumors were treated with open surgery. Either intralesional surgical procedures or en bloc excisions have been described. Furthermore, a variety of chemical or physical adjuvants has been utilized in order to reduce the risk for local recurrence after excision. Currently, there is a shift to more minimally invasive procedures in order to avoid the complications of open surgical excision. Good results have been reported during percutaneous surgery, or the use of embolization. Recently, sclerotherapy has emerged as a promising treatment, showing effective consolidation of the lesions and functional results that appear to be superior to the ones of open surgery. Lastly, non-invasive treatment, such as pharmaceutical intervention with denosumab or bisphosphonates has been reported to be effective in the management of the disease. Radiotherapy has also been shown to confer good local control, either alone or in conjunction to other treatment modalities, but is associated with serious adverse effects. Here, we review the current literature on the methods of treatment of aneurysmal bone cysts. The indication for each type of treatment along reported outcome of the intervention, as well as potential complications are systematically presented. Our review aims to increase awareness of the different treatment modalities and facilitate decision-making regarding each individual patient. PMID:26793296

    Background The simple renal cyst is the most common benign kidney disease. It may cause pain and hypertension, especially if significantly enlarged. As in polycystic kidney disease, blood cell count disturbances are frequently observed in simple renal cysts. The aim of our study was to assess such disturbances, changes in blood pressure, and complication rate in our patients undergoing surgery due to simple renal cyst in the last 10 years. Material/Methods 210 patients with simple renal cysts were underwent surgery between 2002 and 2012. Two different kinds of operation were conducted: aspiration of cyst fluid with injection of sclerosing agent, and laparoscopic/retroperitoneoscopic decortications of the cyst wall. A control group comprised 134 patients with benign prostate hyperplasia. The following data were obtained: cyst burden, hematocrit, hemoglobin, red blood cells, thrombocytes, occurrence of pain, and blood pressure before and after the operation. Complications were collected and presented in Clavien score. Results Hematocrit, hemoglobin, and red blood cells were significantly increased in the experimental group. A positive correlation was observed between cyst burden and the parameters mentioned above. Of 91 patients with hypertension, 56 (61.7%) had blood pressure reduction after the operation. Treatment relieved the loin pain in 132 (88%) patients. Complications occurred in 15 (7.4%) patients. Conclusions Patients with simple renal cysts have high values of red blood cells, hematocrit, and hemoglobin. Treatment decreases blood pressure in patients with hypertension. Complications after treatment are rare and mild. PMID:23811552

    The aim of this study was to evaluate spontaneous bone regeneration after cysts enucleation of the jaws without the use of bone grafting materials. We included 18 patients at random (11 men and 7 women) with a mean age of 31.8 years, with jaw cysts treated by enucleation, without the use of grafting materials. A method of measurements to assess the percentage of reduction of the bone cavities was used to objectify the results. The patients were evaluated before and at least 6 months after surgery, with radiographic scans based on linear measures with a computerized method using Nemoceph program (Nemotec, NemoCeph Software, Madrid, España). The analysis of the sample shows an average of 85.59% decrease in horizontal measures, 89.53% in the vertical, and 88.98 and 89.81% in the diagonal left and right, respectively. The total average reduction was 88.47%. It showed a greater decrease in vertical and diagonal measurements with respect to horizontal. Regeneration in 12 patients was 100% and in 6 patients was higher at 50.4%. Bone density increased in the postoperative radiographs. The results suggest that in some cases, spontaneous bone regeneration can be achieved by cysts enucleation without bone grafting materials. PMID:25709749

    Objectives To examine the effect of 95% ethanol sclerotherapy (EST) administered over 5 minutes on cyst diameter and ovarian tissue in experimentally induced simple ovarian cysts in a rat model. Materials and methods In order to induce ovarian cysts, unilateral total salpingectomy was performed in regularly menstruating adult female Wistar albino rats (n=20) between 12 and 14 weeks of age and weighing between 200 and 220 g. One month after the procedure, the abdominal cavity was opened and 14 rats (70%) were found to have developed macroscopic cysts. Rats with macroscopic cysts (n=14) were assigned into two groups in a prospective and single-blinded manner: group 1 (G1) (n=7), control rats; and group 2 (G2) (n=7), 5-minute EST 95% group. Cyst diameter was measured and recorded for each rat. In G2, after whole cyst fluid was aspirated the cystic cavity was irrigated with 95% ethanol, approximately equal to half of the aspirated cyst volume, after which an interval of 5 minutes was allowed and same amount was re-aspirated and the abdominal cavity was closed. One month after this procedure, abdominal cavities were reopened and intra-abdominal adhesion scoring was performed in both groups. Cyst diameter was measured for each rat, and the right ovary was removed, fixed in 10% formaldehyde, and transported to the laboratory. A histologic assessment of the ovarian tissues was performed under light microscopy following staining with hematoxylin and eosin. Mann–Whitney U-test was used for statistical analysis. A P-level less than 0.05 was considered significant. Results In comparison with G1, there was a statistically significant reduction in the mean ovarian cyst dimensions in G2, while there were no significant differences between the two groups with respect to total number of follicles. Again, a significant increase in apoptotic activity and germinal epithelial degeneration was observed in G2 as compared to G1. The two groups were similar in terms of adhesion formation. Conclusion Although 95% EST results in a reduction in the size of simple ovarian cysts, this effect seems to be achieved at the expense of ovarian tissue injury. PMID:25834392

    Although bone involvement associated with cyst hydatid is rarely seen, it can cause unintended results such as high recurrence rate, infection, sepsis, or amputation of relevant extremity. Because of this reason, its treatment is difficult and disputed. In the case of bifocal bone cyst hydatid in right femur, along with albendazole treatment, result of resecting cyst surgically and its treatment with teicoplanin with added bone cement is given. In conclusion, since the offered treatment method both supports bone in terms of mechanical aspect and also can prevent secondary infection, the method is thought to be a good and safe treatment approach.

    Simple liver cysts are congenital with a prevalence of 2.5%-4.25%. Imaging, whether by US, CT or MRI, is accurate in distinguishing simple cysts from other etiologies, including parasitic, neoplastic, duct-related, and traumatic cysts. Symptomatic simple liver cysts are rare, and the true frequency of symptoms is not known. Symptomatic simple liver cysts are predominantly large (> 4 cm), right-sided, and more common in women and older patients. The vast majority of simple hepatic cysts require no treatment or follow-up, though large cysts (> 4 cm) may be followed initially with serial imaging to ensure stability. Attribution of symptoms to a large simple cyst should be undertaken with caution, after alternative diagnoses have been excluded. Aspiration may be performed to test whether symptoms are due to the cyst; however, cyst recurrence should be expected. Limited experience with both laparoscopic deroofing and aspiration, followed by instillation of a sclerosing agent has demonstrated promising results for the treatment of symptomatic cysts. Here, we describe a patient with a large, symptomatic, simple liver cyst who experienced complete resolution of symptoms following cyst drainage and alcohol ablation, and we present a comprehensive review of the literature.

    Aim. To evaluate the feasibility of percutaneous sclerotherapy of symptomatic simple abdominal cysts, using hypertonic saline and bleomycin, as an alternative to surgery. Materials and Methods. This study involved fourteen consecutive patients (ten women, four men, mean age: 59.2 y) with nineteen symptomatic simple cysts (liver n = 14, kidney n = 3, and adrenal n = 2) treated percutaneously using a modified method. Initially CT-guided drainage was performed; the next day the integrity of the cyst/exclusion of extravasation or communications was evaluated under fluoroscopy, followed by two injections/reabsorptions of the same quantity of hypertonic NaCl 15% solution and three-time repetition of the same procedure with the addition of bleomycin. The catheter was then removed; the patients were hospitalized for 12 hours and underwent follow-ups on 1st, 3rd, 6th, and 12th months. Cyst's volumes and the reduction rate (%) were calculated in each evaluation. Results. No pain or complications were noted. A significant cyst's volume reduction was documented over time (P < 0.001). On the 12th month 17 cysts disappeared and two displayed a 98.7% and 68.9% reduction, respectively. Conclusion. This percutaneous approach constitutes a very promising nonsurgical alternative for patients with symptomatic simple cyst, without complications under proper precautions, leading to eliminating the majority of cysts.

    ABSTRACT A 4-year-old Shih-Tzu, referred for an enlarged left carpus, was diagnosed with a unicameral bone cyst. A customized titanium device was inserted into cystic lesion and fixed by titanium screws. Sufficient strength of the affected bone with the device inserted to maintain limb function was established after resection of contents of cystic lesion. There was no deterioration of the lesion of bone cyst, and acceptable function of the affected limb with no clinical signs of lameness was maintained during 36 months follow-up. The results of this study demonstrated that bone cyst curettage and use of a customized titanium device could provide an effective alternative treatment of huge lesion of unicameral bone cysts with the intent of preventing pathologic fractures.

    Background Cystic lesions of the liver consist of a heterogeneous group of disorders that can present diagnostic and therapeutic challenges. Methods A retrospective review of all medical records of adult patients diagnosed with large (>7 cm) cystic lesions of the liver between January 2000 and December 2011, at Kurume University Hospital. Cases with polycystic disease were excluded. Results Twenty three patients were identified. The mean size was 13.9 cm (range, 7-22cm). The majority of simple cysts were found in women (females: males, 2: 21). In 19 patients, the cyst was removed surgically by wide deroofing (laparoscopically in 16 cases, combined with ethanol sclerotherapy in 13 cases). Infection of the liver cyst occurred in one patient, who later underwent central bi-segmentectomy. Conclusion Simple large cysts of the liver can be successfully treated by laparoscopic deroofing and alcohol sclerotherapy. Large hepatic cyst considered to need drainage should be removed surgically to avoid possible infection. PMID:24098524

    Aneurysmal bone cyst (ABC) is blood filled expansile cystic lesion that most commonly occurs in patients during the second decade of their lives. Traditionally it has been described as a benign lesion but can be locally aggressive and result in the destruction of the involved bone. Treatment methods include surgical excision and curettage with or without bone grafting. We report a proximal femur aneurysmal bone cyst, which resulted in the amputation of the lower extremity, even though all available classic methods of treatment were applied for it. PMID:25725186

    Introduction: Aneurysmal Bone cysts (ABC) are extremely rare in the head and neck region and even rarer in sinuses. ABC is a benign multicystic mass that is locally-destructive and rapidly expandable. Hemorrhagic fluid content (like in this case) and septated appearance are the characteristic feature of ABC. Established treatment options for ABCs include sclerotherapy, embolization, radiotherapy, simple curettage, surgical excision, or a combination of methods. Case Report: In this article, a 5 year-old boy with a recurrent nasal mass is presented. The patient was finally diagnosed with this rare entity: ABC of the paranasal sinuses. The patient was treated through complete surgical removal. Conclusion: ABC can be considered as a rare differential diagnosis of recurrent nasal hemorrhagic mass in a pediatric population.

    Purpose. To evaluate the efficacy and long-term results of single-session 50% acetic acid sclerotherapy for the treatment of simple renal cysts, and to compare the therapeutic results of 5 and 20 min sclerosant dwell techniques. Methods. During the past 9 years, 50% acetic acid sclerotherapy was performed on 67 cysts in 66 patients. An acetic acid volume corresponding to a mean of 23% of the aspirated cyst volume was injected into the cysts. A 20 min dwell time with position changes was performed in 32 cysts (31 patients; group I) and 8% of volume for a 5 min dwell time in 35 cysts (35 patients; group II). Three- and 6-month sonographic or CT follow-up was performed for a minimum of 1 year. Complete regression was defined as no remaining cyst measurable on sonography with or without a scar at the renal cortex. Partial regression was defined as a decreased cyst volume compared with that before sclerotherapy. The Mann-Whitney U-test was used to compare the therapeutic results between the two groups. Results. For 67 simple renal cysts, complete regression on follow-up was observed in 21 of 32 cysts (66%; group I) and 22 of 35 cysts (63%; group II); the remaining 24 cysts all showed partial regression. The partial reduction rate of the cyst's volume was 97.4% (91.3-99.4%) in group I and 96.9% (90.8-99.5 %) in group II. There were no procedure-related major complications, and no statistically significant differences in the complete regression and partial volume reduction rates between the two groups (p > 0.05). Conclusion. Fifty percent acetic acid is an effective and safe sclerosing agent for simple renal cysts. Fifty percent acetic acid sclerotherapy with a 5 min sclerosant dwell time, using a volume of about 10% of the aspirated volume, is sufficient for satisfactory results of simple renal cyst sclerotherapy.

    Background?Aneurysmal bone cysts (ABCs) are benign bony lesions that rarely affect the skull base. Very few cases of temporal bone ABCs have been reported. We describe the first case of a temporal bone ABC that was thought to be consistent with a meningioma based on preoperative magnetic resonance imaging (MRI) findings. Clinical Presentation?An otherwise healthy 23-year-old woman presented with a pulsatile noise in her left ear and a 4-week history of throbbing headache with nausea. There was no associated emesis, visual or auditory changes, or other neurologic features. Neurologic examination revealed a left lower motor neuron facial paresis. Computed tomography and MRI studies demonstrated a large lesion in the left middle cranial fossa skull base with erosion of the petrous temporal bone. Based on the presence of a “dural tail” on preoperative contrast-enhanced T1-weighted imaging, the lesion was interpreted to likely be consistent with a meningioma. An orbitozygomatic approach was utilized for surgical excision. Histopathologic evaluation was consistent with an ABC. Conclusion?Postoperatively the patient had improvement in the lower motor neuron facial paresis. It is important to consider ABC in the differential diagnosis of intracranial lesions accompanied by the dural tail sign on MRI. PMID:26251800

In adults, these cysts are related to intra-articular lesions, which may consist of meniscal lesions or arthrosis. In children, these cysts are usually found on physical examination or imaging studies, and they generally do not have any clinical relevance. Ultrasound examination is appropriate for identifying and measuring the popliteal cyst. The main treatment approach should focus on the joint lesions, and in most cases there is no need to address the cyst directly. Although almost all knee cysts are benign (Baker's cysts and parameniscal cysts), presence of some signs makes it necessary to suspect malignancy: symptoms disproportionate to the size of the cyst, absence of joint damage (e.g. meniscal tears) that might explain the existence of the cyst, unusual cyst topography, bone erosion, cyst size greater than 5 cm and tissue invasion (joint capsule).

    The aneurysmal bone cyst is a pseudotumoral lesion that can take several aspects. This is a rare lesion representing 1% of bone tumors. It appears usually during the first 30 years of life. The pathogenesis is that of a process of “dysplasia/hyperplasia”, favored by a circulatory deficiency and hemorrhage within the lesion and the phenomena of osteoclasis. The objective of this work is to illustrate with analysis, the specific forms and atypical aneurysmal bone cyst which often pose a diagnostic challenge requiring radiological investigation with histological confirmation. We report eight pediatric cases of aneurysmal cysts collected over a period of 3 years, 3 boys and 5 girls. All patients had standard radiographs. MRI was performed in three patients. The diagnosis was confirmed histologically. The atypia has been in the seat: fibula (1 case), metaphyseal (2 cases), diaphyseal (4 cases) and metatarsal (1 case). Aneurysmal bone cyst is a rare benign tumor with predilection to the metaphysis of long bones. Atypical forms even fewer are dominated by the atypical seat. PMID:24244797

    Osteochondrosis arises as a result of focal failure of the blood supply to growth cartilage. The current aim was to examine the pathogenesis of pseudocysts and true cysts in subchondral bone following failure of the blood supply to the articular-epiphyseal cartilage complex in horses. Cases were recruited based on identification of lesions (n = 17) that were considered likely to progress to or to represent pseudocysts or true cysts in epiphyseal bone in histological sections and included 10 horses ranging in age from 48 days to 5 years old. Cases comprised 3 warmbloods, 3 Standardbreds, 1 Quarter horse and 1 Arabian with spontaneous lesions and 2 Fjord ponies with experimentally induced lesions. Seven lesions consisted of areas of ischemic chondronecrosis and were compatible with pseudocysts. Two lesions were located at intermediate depth in epiphyseal growth cartilage, 2 lesions were located in the ossification front, 2 lesions were located in epiphyseal bone and 1 lesion was located in the metaphyseal growth plate (physis). Ten lesions contained dilated blood vessels and were compatible with true cysts. In 2 lesions the dilated blood vessels were located within the lumina of failed cartilage canals. In the 8 remaining lesions areas of ischemic chondronecrosis were associated with granulation tissue in the subjacent bone and dilated vessels were located within this granulation tissue. Failure of the blood supply and ischemic chondronecrosis can lead to formation of pseudocysts or dilatation of blood vessels and formation of true cysts in the epiphyseal bone of horses.

    We describe the spontaneous rupture of a simple hepatic cyst. A 62-year-old woman was admitted for right upper quadrant pain of sudden onset. The patient denied a history of abdominal trauma. Computed tomography of the abdomen showed a 13-cm-diameter solitary hepatic cyst in the right lobe. Part of the cyst surface was irregular, and the internal echo was heterogeneous. Retained fluid was detected under the liver capsule. Ten days after admission, computed tomography revealed that the volume of fluid retained under the liver capsule had decreased but that the hepatic cyst had enlarged again. The patient was referred to our hospital for further evaluation and treatment. Physical examination revealed mild right upper quadrant pain, but no signs or symptoms of peritonitis or abnormalities of the chest or heart. Percutaneous puncture was performed with a needle and an 8-French pigtail catheter under ultrasonographic guidance. Brown serous fluid was aspirated. After the removal of approximately 1,000 mL of fluid, contrast medium was injected to check for communications between the cyst and the biliary tree and to document the absence of leakage into the peritoneal cavity. After complete aspiration of the cyst fluid, 200 mg of minocycline hydrochloride dissolved in 10 mL of saline was injected into the cyst, and the catheter was flushed with 10 mL of saline (total volume of saline, 20 mL). The catheter was then clamped for 30 minutes. After percutaneous aspiration, the patient's symptoms resolved. Minocycline hydrochloride was injected daily for 7 days, and the catheter was removed. There has been no evidence of recurrence after 2 years. PMID:25959204

    Purpose Although angiogenesis has been implicated in the promotion of renal cyst growth in autosomal dominant polycystic kidney disease, no studies have investigated the role of angiogenesis in the growth of simple renal cysts. The aim of current study was to investigate the effect of chemotherapy with the antivascular endothelial growth factor antibody bevacizumab on renal cyst development and growth in cancer patients. Materials and Methods We retrospectively reviewed the medical records of 136 patients with a variety of cancers that were treated with bevacizumab-based chemotherapy for metastatic disease. The presence of and changes in renal cysts were evaluated by retrospective analysis of computed tomography scans performed for assessment of tumor response to bevacizumab-based therapy. Results The median age of the patients was 64 years. Renal cysts were identified in 66 patients, in whom 33 (50%) had a single cyst and the rest had 2 or more cysts. The average dose of bevacizumab was 2.68 mg/kg per week. Median duration of treatment was 33 weeks. Average cyst size was 1.9±2.4 cm at the beginning of the study and the majority of the cysts (54 patients, 84%) did not change in size or shape during bevacizumab treatment. No patients were identified with new cysts. Cyst size changed in 10 patients (16%): an increase of 15% to 40% from the baseline size in 5 patients and a decrease in size of 10% to 70% in another 5 patients. The duration of bevacizumab therapy was significantly longer in the subgroup of patients with diminished or increased cyst size than in the patients with stable cyst size: 62 weeks versus 29 weeks, respectively (p=0.0002). Conclusions Our data demonstrated that simple renal cysts were stable in size and number in the vast majority of cancer patients treated with bevacizumab. PMID:26682018

    Management of unicameral bone cysts (UBC) remain controversial. These cysts seldom heal spontaneously or even after pathological fracture. Sometimes these cysts can be very large and incredibly troublesome to the patient. Various treatments exist with variable success rates. We present our experience of treating these lesions by continuous drainage. Over a seven year period, six patients with unicameral bone cysts were treated by inserting a modified drain into the wall of the cyst. The aim of surgery was to place the drain in a dependent area of the cyst, through the cortex allowing for continuous drainage. This was achieved through a small incision under radiographic control. A cement restrictor (usually used for femoral canal plugging during total hip replacements) was modified and inserted to prevent closure of the drain site. A redivac drain was passed through the plug into the cyst. The drain was left in place for a week to establish an epithelialized pathway which hopefully would remain patent, into the subcutaneous tissues, after the drain had been removed. There were four males and two females in the group and the age range was 6 -12 years. Four of the lesions were in the upper humerus, one in the proximal femur and the other one in the proximal tibia. Healing was rated according to the modified Neer classification. Grade 1 (healed) and Grade 2 (healed with defect) was defined as excellent outcome. Persistent /Recurrent cysts (Grade 3 and 4) were noted as unsatisfactory. Five cases were completely healed. Only one had a further fracture and there were no recurrent fractures. All the patients reported complete comfort and they all were able to re-engage in recreational activities without restriction. We think that reducing the intra-medullary pressure in these lesions will lead to healing. We report a safe and minimally invasive technique for the management of UBC. PMID:26587064

    Bone defects can occur in various forms and present challenges to performing a standard micro-CT evaluation of bone quality because most measures are suited to homogeneous structures rather than ones with spatially focal abnormalities. Such defects are commonly associated with pain and fragility. Research involving bone defects requires quantitative approaches to be developed if micro-CT is to be employed. In this study, we demonstrate that measures of inter-microarchitectural bone spacing are sensitive to the presence of focal defects in the proximal tibia of two distinctly different mouse models: a burr-hole model for fracture healing research, and a model of osteolytic bone metastases. In these models, the cortical and trabecular bone compartments were both affected by the defect and were, therefore, evaluated as a single unit to avoid splitting the defects into multiple analysis regions. The burr-hole defect increased mean spacing (Sp) by 27.6%, spacing standard deviation (SpSD) by 113%, and maximum spacing (Spmax) by 72.8%. Regression modeling revealed SpSD (?=0.974, p<0.0001) to be a significant predictor of the defect volume (R(2)=0.949) and Spmax (?=0.712, p<0.0001) and SpSD (?=0.271, p=0.022) to be significant predictors of the defect diameter (R(2)=0.954). In the mice with osteolytic bone metastases, spacing parameters followed similar patterns of change as reflected by other imaging technologies, specifically bioluminescence data which is indicative of tumor burden. These data highlight the sensitivity of spacing measurements to bone architectural abnormalities from 3D micro-CT data and provide a tool for quantitative evaluation of defects within a bone.

  3. Clinical factors affecting pathological fracture and healing of unicameral bone cysts

    2014-01-01

    Background Unicameral bone cyst (UBC) is the most common benign lytic bone lesion seen in children. The aim of this study is to investigate clinical factors affecting pathological fracture and healing of UBC. Methods We retrospectively reviewed 155 UBC patients who consulted Nagoya musculoskeletal oncology group hospitals in Japan. Sixty of the 155 patients had pathological fracture at presentation. Of 141 patients with follow-up periods exceeding 6 months, 77 were followed conservatively and 64 treated by surgery. Results The fracture risk was significantly higher in the humerus than other bones. In multivariate analysis, ballooning of bone, cyst in long bone, male sex, thin cortical thickness and multilocular cyst were significant adverse prognostic factors for pathological fractures at presentation. The healing rates were 30% and 83% with observation and surgery, respectively. Multivariate analysis revealed that fracture at presentation and history of biopsy were good prognostic factors for healing of UBC in patients under observation. Conclusion The present results suggest that mechanical disruption of UBC such as fracture and biopsy promotes healing, and thus watchful waiting is indicated in these patients, whereas patients with poor prognostic factors for fractures should be considered for surgery.

  4. Secondary brain abscess following simple renal cyst infection: a case report

    PubMed Central

    2014-01-01

    Background Escherichia coli (E. coli) is the most common causative bacteria of neonatal meningitis, but hematogenous intracranial E. coli infection is rare in adults. Moreover, intracranial abscess formation owing to E. coli, including brain abscesses and subdural empyema formation, is extremely rare. We herein present a case involving a patient with a brain abscess owing to E. coli following a simple renal cyst infection. A review of the literature is also presented. Case presentation A 77-year-old Japanese woman with a history of polymyalgia rheumatica was admitted to our hospital because of persistent fever, right flank pain, and pyuria. Intravenous antibiotics were administered; however, her level of consciousness deteriorated 6 days after admission. Contrast-enhanced magnetic resonance imaging showed a brain abscess in the left occipital lobe and pyogenic ventriculitis. Enhanced abdominal computed tomography revealed a right renal cyst with heterogeneous content. Culture of urine, blood, and aspirated pus from the infected cyst revealed E. coli with identical antibiotic sensitivity in all sites, suggesting that the cyst infection and subsequent bacteremia might have caused the brain abscess. The patient recovered after a 6-week course of meropenem. Conclusion The prognosis of patients with E. coli-associated intracranial abscess is usually poor. Advanced age and immunosuppression may be potent risk factors for intracranial abscess formation owing to the hematogenous spread of E. coli. PMID:24934996

    OBJECTIVE To determine morphological characteristics of subchondral bone cysts (SBCs) in medial femoral condyles (MFCs) of adult horses with orthopedic disease. SAMPLE CT scans of 7 MFCs with SBCs from 6 adult horses. PROCEDURES CT was used to determine the volume, surface area, and centers of the articular cyst opening and SBC in each MFC. Cysts were ordered from smallest to largest on the basis of volume. Osseous pathological characteristics of the MFC were assessed in the frontal plane. Three-dimensional distance of displacement between the center of the articular cyst opening and center of the cyst was determined for each SBC. Cyst surface area-to-volume ratio was evaluated and compared with that of a true sphere. RESULTS All SBCs had a defect in the subchondral bone plate at the cranial 15% to 20% of the MFC. Cyst center was located in a caudal, proximal, and abaxial direction with respect to the center of the articular cyst opening for each horse. Small- and intermediate-volume SBCs were irregular and multilobulated, whereas large-volume SBCs were smooth and discrete with a surface area-to-volume ratio approaching that of a sphere. CONCLUSIONS AND CLINICAL RELEVANCE Consistency in morphological characteristics suggested a common etiopathogenesis for SBCs in MFCs of adult horses. Cyst enlargement may have been attributable to a biomechanical predisposition to decrease the surface area-to-volume ratio, resulting in a spherical cyst. PMID:26919597

    2015-01-01

    Introduction Aneurysmal bone cyst occurring in the setting of previously diagnosed fibrous dysplasia is rare. While both are benign processes, pain, compression of nearby structures and risk of fracture can require treatment. Presentation of case In this report, we describe a 56 year old male who developed an aggressive aneurysmal bone cyst secondary to fibrous dysplasia in the proximal tibia over a period of 8 months. He required an above knee amputation for disease and symptom control due to the aggressive nature of disease and medical comorbidities. Discussion The diagnosis of a secondary lesion can prove difficult. It is important to exclude a malignant disease process, particularly when imaging demonstrates an aggressive appearance. In this case, repeat imaging, CT guided biopsies and an open biopsy were performed to exclude malignancy prior to definitive surgical management. Conclusion In order to exclude secondary lesions, we suggest further investigation for new onset pain in the setting of a benign lesion. PMID:26011801

    Giant cell tumor is colonized by aneurismal bone cyst in only 15% of cases and cervical localisation accounts for less than 1% of giant cell tumors. We are reporting a rare case of a C2 hypervascularized giant cell tumor colonized by an aneurismal bone cyst treated with an effective preoperative Onyx embolization followed by a full tumor resection. The patient experienced a moderate cervical spine injury 2 months prior admission followed by a progressive stiff neck and cervicalgia. CT and MRI identified a lytic lesion of the body and lateral masses of the C2 with encasement of both vertebral arteries. The angiography showed a hypervascularization of the lesion from the vertebral and external carotid arteries as well as a thrombosis of the V3 segment of the right vertebral artery at the C1 level. A posterior occipito-C3/C4 fixation and a tumor biopsy were performed. Histopathological examination concluded to a giant cell tumor colonized by an aneurismal bone cyst. Three weeks later, the patient developed a right upper extremity deficit. The MRI showed an increased C1-C2 stenosis and an increase of the hypervascularization. Three sessions of embolization by the onyx were performed. During surgery a near total tumor devascularisation was observed and a complete resection of the tumor was achieved through an anterolateral approach. Reconstruction consisted of a cementoplasty of the C2 body and odontoïd process with an anterior C3-prosthesis plate. The postoperative course was uneventful. PMID:22695034

    We present a case report of a 33-year-old woman with back pain for several months which was resistant to medical treatment. Thoracolumbar MRI and multidetector CT showed an aneurysmal bone cyst intersecting the body and pedicles of L5. Minimally invasive treatment was performed with percutaneous injection of osteoconductive cement (Cerament) to induce sclerosis and bone remodeling of the bone cyst lesion with an analgesic effect. Before treatment, spinal angiography was performed to exclude arterial afferents. No bone biopsy was done. Under general anesthesia and fluoroscopic guidance, a first vertebroplasty was performed by a bilateral transpedicular approach using the osteoconductive cement followed 2?months later by a second treatment with CT-fluoro-guided direct injection of Cerament. No complications occurred during the procedure. At 4 and 6?months follow-up the MRI/CT showed sclerotic bone remodeling of the walls of the aneurysmal cyst with clinical improvement. PMID:24186854

    Endodermal cyst is a rare developmental cyst of the CNS, such as a Rathke cleft and colloid cyst lined by columnar epithelium of presumed endodermal origin. Intracranial endodermal cysts are rare, and most are found in the posterior fossa. The authors report a case of petroclival endodermal cyst with extensive bone destruction. A 12-year-old boy presented with transient facial weakness and headache. Imaging revealed a 3 × 3 × 4-cm, partial rim, enhanced cystic lesion in the petroclival area that was isointense on T1-weighted imaging and hyperintense in T2-weighted imaging. The cyst wall was partially removed and the cyst was obliterated using a lateral approach. Histological examination revealed ciliated, simple-to-pseudostratified cuboidal epithelium with a basement membrane that was consistent with an endodermal cyst, with the rare finding of xanthogranulomatous changes.

Radiograph demonstrated a lytic lesion in the medial cuneiform extending on to the middle cuneiform, the navicular bone and the base of the first metatarsal. En bloc resection of the lesion was performed using a dorsal longitudinal incision along the first ray. Tricortical iliac crest graft was harvested and shaped to fill the defect. Two drill holes were made and the tibialis anterior tendon was attached to the graft. Prepared, morcellised allograft was placed along the junction of autograft and host bone. At 1-year follow-up, the patient was pain free, the medial arch of the foot was maintained and the graft had united with the host bone. PMID:24563041

    Thyroglossal duct cyst presents most frequently in the midline of the neck, either at or just below the level of the hyoid bone. They generally manifest as painless neck swelling, and they move on protrusion of tongue and during swallowing. A case of thyroglossal cyst was reported in the left submandibular region in a 14-year-old girl, above the level of hyoid bone; ultrasound examination favored a cystic lesion which moved in a vertical fashion on swallowing whereas fine needle aspiration cytology report was suggestive of simple cystic lesion of thyroglossal cyst. No lymphoid or malignant cells were present. The cyst was excised completely by surgical procedure under general anesthesia. Histopathological analysis revealed thyroglossal cyst showing columnar and flattened epithelium of cyst with focal aggregate of chronic inflammatory cells supported by fibrocollagenous cyst wall. The clinical, ultrasound, and histopathological findings suggested that the lesion was an infected thyroglossal cyst. There was no evidence of recurrence 6 months after surgery. PMID:22567451

    We validated the association of simple renal cysts with abdominal aortic aneurysm and other cardiovascular factors and assessed simple renal cysts' impact on renal function before and after endovascular abdominal aortic aneurysm repair. A retrospective analysis of prospectively collected data was conducted. Computed tomography angiograms of 100 consecutive male patients with abdominal aortic aneurysm who underwent endovascular abdominal aortic aneurysm repair (Group 1) were reviewed and compared with 100 computed tomography angiogram of aged-matched male patients without abdominal aortic aneurysm (Group 2). Patients' demographic data, risk factors, abdominal aortic aneurysm diameter, the presence of simple renal cyst and laboratory tests were recorded. No difference was observed between the two groups in respect to other cardiovascular risk factors except hyperlipidemia with higher prevalence in Group 1 (p < 0.05). Presence of simple renal cysts was independently associated with age (p < 0.05) and abdominal aortic aneurysm (p = 0.0157). There was no correlation between simple renal cysts and abdominal aortic aneurysm size or pre-operative creatinine and urea levels. No difference was observed in post-operative creatinine and urea levels either immediately after endovascular abdominal aortic aneurysm repair or in 12-month follow-up. In male patients, the presence of simple renal cysts is associated with abdominal aortic aneurysm and is increasing with age. However, their presence is neither associated with impaired renal function pre-endovascular abdominal aortic aneurysm repair and post-endovascular abdominal aortic aneurysm repair nor after 12-month follow-up.

    2015-01-01

    Purpose This study evaluated the healing in cystic defect of the jaw to substantiate our understanding of spontaneous bone healing after enucleation of jaw cysts subjectively and with analysis of digital postoperative panoramic radiographs. Materials and Methods Fourty four consecutive patients reporting to the Department of Dental and Oral Surgery, during the period between 2008-2012 having maxillary and mandibular cysts treated by either surgical enucleation or by marsupialization followed by enucleation were evaluated for subsequent bone formation at the site of cystectomy defect by subjective clinical examination along with digital radiographic examination. Postoperative clinical and radiographic examinations were performed at 6,9,12, and 24 months. Bone regeneration was evaluated by reduction of the size of residual cavities at the cystectomy defect using digital orthopantomogram. Results Out of 44 patients 15 patients completed two years of follow-up with all the patients having 6 months follow-up. The maximum size of the cystic pathology was 150.40mm and minimum of 14.73mm at the time of presentation (average size of 58.16mm). Twenty patients were diagnosed with odontogenic keratocyst, with one patient having multiple OKC associated with Gorlin Goltz Syndrome, 17 patients had dentigerous cyst, 5 had Radicular cyst; solitary bone cyst and globulomaxillary cyst formed one each. Uneventful healing and spontaneous filling of the residual cavities were obtained in all cases. The digital analysis of the postoperative radiographs showed mean values of reduction in size of the residual cavity of 25.85% after 6 months, 57.13% after 9 months, 81.03% after one year and 100% after two year. Conclusion Spontaneous bone regeneration can occur after surgical removal of jaw cysts without the aid of any graft materials even in large cystic cavity sufficiently surrounded by enough bony walls. This simplifies the surgical procedure, decreases the overall cost of surgery, and reduces the risk of postoperative complications associated with grafting. PMID:26501020

    An aneurysmal bone cyst (ABC) is a type of reactive reparative bone neoplasm that rarely occurs in the head and neck. To date, only a small number of cases have been previously reported. The present study reports the case of a 58-year-old male who presented with a tumor in the laryngeal cricoid cartilage, a rare position for a tumor, who subsequently underwent treatment by surgical resection. Based on the observations of the present study and a literature review, it was concluded that an ABC of the larynx can be identified based on a combination of radiology and postoperative histopathology examinations. However, following a tracheotomy and excision, the difficulty of performing tracheal cannula removal is inevitable. The present study described in detail a rare disease, ABC, occurring in the larynx. More cases are required for follow-up studies. PMID:26622349

    The patella is an unusual location for primary and metastatic bone tumors to develop. The most frequently encountered primary osteolytic lesions at the patella include giant cell tumors of the bone (GCT), chondroblastoma and aneurysmal bone cysts (ABC). However, the presentation of an ABC originating secondary to a GCT at the patella is rare. The present study describes such a case in a 46-year-old female. The differential diagnosis of the condition was extensive. The patient underwent curettage and the addition of bone cement to fill the defect. Pathological analysis of the resected tissue demonstrated that the lesion was consistent with an ABC forming secondary to a GCT. A 3-month follow-up was completed subsequent to the surgery, with a computed tomography scan demonstrating no evidence of recurrence. However, frequent and continuous observations of the patient following diagnosis are planned in order to evaluate the long-term efficacy of the surgical treatment. To the best of our knowledge, the present study describes the third reported case in the literature of this rare, double synchronous, benign tumor located at the patella. PMID:26893764

    The authors describe the case of a 6.6-cm symptomatic spinal aneurysmal bone cyst (ABC) in a 17-year-old athlete treated percutaneously. Surgical treatment was not considered as the first option owing to its invasiveness and associated morbidity. CT-guided cryoablation of the expansile part of the ABC was performed for tumour shrinkage and nerve decompression. Thermal insulation, temperature monitoring and functional control/electrostimulation of the neural structures at risk were applied. Finally, the bony defect was cemented. No complications occurred during the procedure. Complete resolution of the ABC on imaging and clinical improvement were achieved. Percutaneous cryoablation should be considered as an alternative treatment option, especially when tumour size reduction is desired. PMID:25091121

    Aneurysmal bone cysts (ABCs) involving condyle are unusual clinical presentation affecting younger group of society with only 12 cases reported till today in English literature. In this case of ABC condyle following resection, reconstruction of temporomandibular joint was done by alloplastic condylar prosthesis as a primary choice. Monthly basis follow-up was done for 1-year with a successful result. Reviewing the reconstructive options used in ABC condyle cases we found that the condylar head add-on system has shown a satisfactory result in comparison to costochondral graft with no donor site morbidity. We recommend condylar head add-on system should be preferred as a primary reconstructive option, reserving the autograft for recurrence cases.

    With greater than 500,000 orthopaedic procedures performed in the United States each year requiring a bone graft, the development of novel graft materials is necessary. We report that some porous polymer/ceramic composite scaffolds possess intrinsic osteoinductivity as shown through their capacity to induce in vivo host osteoid mineralization and in vitro stem cell osteogenesis making them attractive synthetic bone graft substitutes. It was discovered that certain low crystallinity ceramics partially dissociate into simple signaling molecules (i.e., calcium and phosphate ions) that induce stem cells to endogenously produce their own osteoinductive proteins. Review of the literature has uncovered a variety of simple signaling molecules (i.e., gases, ions, and redox reagents) capable of inducing other desirable stem cell differentiation through endogenous growth factor production. Inductive simple signaling molecules, which we have termed inducerons, represent a paradigm shift in the field of regenerative engineering where they can be utilized in place of recombinant protein growth factors.

    Juvenile psammomatoid ossifying fibroma is a gradually progressive, aggressive extragnathic craniofacial tumor of bone. Due to its complex histogenesis, biological behavior, histology, and classification, its nomenclature has always been the focus of debate among pathologists. Based on the clinical behavior and histology, the term psammous desmo-osteoblastoma (PDO) is an apt expression for this lesion. Immunohistochemical investigation with anti-osteonectin shows positivity for spindle cells whereas psammoma bodies are negative. These results shore up the hypothesis of osteogenic differentiation of the undifferentiated mesenchymal cells of the periodontal ligament that may be responsible for the aggressive behavior of the lesion. Aneurysmal bone cysts (ABCs) are known to be secondarily associated with primary osseous neoplasms like ossifying fibroma, giant cell granuloma, etc. We report a rare case of PDO with concomitant ABC in the mandible of a 30-year-old male patient. The present lesion had recurred at the same site of an osteolytic lesion diagnosed 7 years ago as a benign fibro-osseous lesion and treated by conservative surgical curettage. The histological presentation substantiated by special stains and immunohistochemistry point to the diagnosis of psammous desmo-osteoblastoma with a concomitant ABC. Review of the literature revealed the presentation to be rare with very few cases reported till date. PMID:26389053

    An unmet need remains for a bone graft substitute material that is biocompatible, biodegradable and capable of promoting osteogenesis safely in vivo. The aim of this study was to investigate the use of a novel collagen-hydroxyapatite (CHA) bone graft substitute in the clinical treatment of a mandibular bone cyst in a young horse and to assess its potential to enhance repair of the affected bone. A 2 year-old thoroughbred filly, presenting with a multilobulated aneurysmal bone cyst, was treated using the CHA scaffold. Post-operative clinical follow-up was carried out at 2 weeks and 3, 6 and 14 months. Cortical thickening in the affected area was observed from computed tomography (CT) examination as early as 3 months post-surgery. At 14 months, reduced enlargement of the operated mandible was observed, with no fluid-filled area. The expansile cavity was occupied by moderately dense mineralized tissue and fat and the compact bone was remodelled, with a clearer definition between cortex and medulla observed. This report demonstrates the promotion of enhanced bone repair following application of the CHA scaffold material in this craniomaxillofacial indication, and thus the potential of this material for translation to human applications.

    Treatment of hepatic cysts should be considered only for those patients who are symptomatic. For simple cysts, percutaneous aspiration invariably leads to recurrence; laparoscopic deroofing is usually curative. Open deroofing (fenestration) should be reserved for cysts inaccessible by laparoscopy. Percutaneous instillation of sclerosing agents (ethanol, iophendylate, minocycline) into nonbiliary and nonparasitic cysts is an alternative therapeutic option in certain cases. Due to increased morbidity, hepatic resection should be reserved for polycystic liver disease, diffuse hepatic involvement, or recurrence after a deroofing procedure. Patients with congenital fibropolycystic disorders (eg, congenital hepatic fibrosis) with evidence of hepatic decompensation, should be considered for liver transplantation. For hepatic hydatid cysts, simple cystectomy or the PAIR (puncture, aspirate, inject, and reaspirate) technique with albendazole treatment have been shown to be equally successful. In the case of alveolar echinococcosis, hepatic resection and liver transplantation are the only effective modalities for localized and extensive hepatic disease, respectively. PMID:11096603

    Arginine vasopressin (AVP) has a key role in osmoregulation by facilitating water transport in the collecting duct. Recent evidence suggests that AVP may have additional effects on renal function and favor cyst growth in polycystic kidney disease. Whether AVP also affects kidney structure in the general population is unknown. We analyzed the association of copeptin, an established surrogate for AVP, with parameters of renal function and morphology in a multicentric population-based cohort. Participants from families of European ancestry were randomly selected in three Swiss cities. We used linear multilevel regression analysis to explore the association of copeptin with renal function parameters as well as kidney length and the presence of simple renal cysts assessed by ultrasound examination. Copeptin levels were log-transformed. The 529 women and 481 men had median copeptin levels of 3.0 and 5.2 pmol/L, respectively (P<0.001). In multivariable analyses, the copeptin level was associated inversely with eGFR (?=-2.1; 95% confidence interval [95% CI], -3.3 to -0.8; P=0.002) and kidney length (?=-1.2; 95% CI, -1.9 to -0.4; P=0.003) but positively with 24-hour urinary albumin excretion (?=0.11; 95% CI, 0.01 to 0.20; P=0.03) and urine osmolality (?=0.08; 95% CI, 0.05 to 0.10; P<0.001). A positive association was found between the copeptin level and the presence of renal cysts (odds ratio, 1.6; 95% CI, 1.1 to 2.4; P=0.02). These results suggest that AVP has a pleiotropic role in renal function and may favor the development of simple renal cysts. PMID:25270071

We did an en bloc excision of locally aggressive tumor through anterior plus posterior approach and stabilization by lateral mass screw fixation and anterior cervical instrumentation. Involvement of several adjacent cervical vertebrae by an aneurysmal bone cyst is rare, and conventional treatment with curettage and bone grafting is most likely to carry a high rate of recurrence and spinal instability. We recommend complete excision of the tumor and instrumentation in a single stage to avoid instability. PMID:26288549

    Aneurysmal bone cyst (ABC) is a vascular tumor of the spine. Management of spinal ABC still remains controversial because of its location, vascular nature and incidence of recurrence. In this manuscript, we hereby describe two cases of ABC spine treated by curettage, vertebral cement augmentation for control of bleeding and internal stabilization with two years followup. To the best of our knowledge, this is the first case report in the literature describing the role of cement augmentation in spinal ABC in controlling vascular bleeding in curettage of ABC of spine. Case 1: A 22 year old male patient presented with chronic back pain. On radiological investigation, there were multiple, osteolytic septite lesions at L3 vertebral body without neural compression or instability. Percutaneous transpedicular biopsy of L3 from involved pedicle was done. This was followed by cement augmentation through the uninvolved pedicle. Next, transpedicular complete curettage was done through involved pedicle. Case 2: A 15-year-old female presented with nonradiating back pain and progressive myelopathy. On radiological investigation, there was an osteolytic lesion at D9. At surgery, decompression, pedicle screw-rod fixation and posterolateral fusion from D7 to D11 was done. At D9 level, through normal pedicle cement augmentation was added to provide anterior column support and to control the expected bleeding following curettage. Transpedicular complete curettage was done through the involved pedicle with controlled bleeding at the surgical field. Cement augmentation was providing controlled bleeding at surgical field during curettage, internal stabilization and control of pain. On 2 years followup, pain was relieved and there was a stable spinal segment with well filled cement without any sign of recurrence in computed tomography scan. In selected cases of spinal ABC with single vertebral, single pedicle involvement; cement augmentation of vertebra through normal pedicle has an important role in surgery aimed for curettage of vertebra.

    Background: Functional ovarian cysts include follicular, corpus luteum, and theca lutein cysts are the most common adnexal masses (about 50%) in women of reproductive age. Treatment with the combined monophasic oral contraceptives reduces functional ovarian cysts. Yaz (drospirenone/ethinyl estradiol) is a low-dose combined oral contraceptive pill containing 20 μg ethinyl estradiol and 3 mg drospirenone. In addition to contraceptive effects, Yaz has anti-mineralocorticoid and anti-adrenergic effects. Ovocept- low-dose LD is also a low-dose combined oral contraceptive drug containing 30 μg ethinyl estradiol and 3 mg norgestrol. Ovocept-LD has some side-effects such as weight gain, spotting, breast tenderness, nausea, and headache. Materials and Methods: Being a clinical study, the present research was carried out on 42 patients with the simple ovarian cysts from 2010 to 2012. 84 Patients were assigned to A and B groups. Group A received Yaz once a day for a period of 28 days and group B received Ovocept-LD once a day for a period of 21 days. After treating by Yaz and Ovocept-LD, Cysts were evaluated by ultrasound. Results were analyzed by the SPSS software. A P < 0.05 was considered the significance threshold. Results: Obtained results indicated that both Yaz and Ovocept-LD had an effect on the simple ovarian cysts. Statistical tests, however, has shown that the effect of Yaz has been significantly more than that of Ovocept-LD. Conclusion: Given the faster and better recovery effect, and the lesser side effects of Yaz as compared to Ovocept-LD, it is recommended to use Yaz for the simple ovarian cysts. PMID:25337535

    The soybean cyst nematode (SCN) is a major cause of soybean yield reduction. The objective of this study was to evaluate the efficiency of marker-assisted selection to identify genotypes resistant to SCN race 3 infection, using Sat_168 and Sat-141 resistance quantitative trait loci. The experiment was carried out under greenhouse conditions, using soybean populations originated from crosses between susceptible and resistant parent stock: CD-201 (susceptible) and Foster IAC (resistant), Conquista (susceptible) and S83-30 (resistant), La-Suprema (susceptible) and S57-11 (resistant), and Parecis (susceptible) and S65-50 (resistant). Plants were inoculated with SCN and evaluated according to the female index (FI), those with FI < 10% were classified as resistant to nematode infection. Plants were genotyped for SCN resistance using microsatellite markers Sat-141 and Sat_168. Marker selection efficiency was analyzed by a contingency table, taking into account genotypic versus phenotypic evaluations for each line. These markers were shown to be useful tool for selection of SCN race 3. PMID:26985946

    Aneurysmal bone cyst (ABC) is an aggressive, pediatric bone tumor characterized by extensive destruction of the surrounding bone. Though first described over 60 years ago, its molecular etiology remains poorly understood. Recent work revealed that ABCs harbor translocation of TRE17/USP6, leading to its transcriptional upregulation. TRE17 encodes a ubiquitin-specific protease (USP), and a TBC domain that mediates binding to the Arf6 GTPase. However, the mechanisms by which TRE17 overexpression contributes to tumor pathogenesis, and the role of its USP and TBC domains are unknown. ABCs are characterized by osteolysis, inflammatory recruitment, and extensive vascularization, processes in which matrix proteases play a prominent role. This led us to explore whether TRE17 regulates the production of matrix metalloproteinases (MMPs). In the current study, we demonstrate that TRE17 is sufficient to induce expression of MMP-9 and MMP-10, in a manner requiring its USP activity, but not its ability to bind Arf6. TRE17 induces transcription of MMP-9 through activation of NF?B, mediated in part by the GTPase RhoA and its effector kinase, ROCK. Furthermore, xenograft studies demonstrate that TRE17 induces formation of tumors that reproduce multiple features of ABC, including a high degree of vascularization, with an essential role for the USP domain. In sum, these studies reveal that TRE17 is sufficient to initiate tumorigenesis, identify MMPs as novel TRE17 effectors that likely contribute to ABC pathogenesis, and define the underlying signaling mechanism of their induction.

    Objective: The aim of this study was to evaluate the efficacy and safety of ultrasound guided percutaneous sclerotherapy of symptomatic simple renal cysts with n-butyl cyanoacrylate (NBCA) and iodized oil mixture as an outpatient single session procedure. Materials and Methods: A total of ninety two patients with 100 symptomatic simple renal cysts (larger than 5 cm) were treated by ultrasound (US)-guided percutaneous aspiration and injection of NBCA and iodized oil mixture. The patients (68 men and 24 women, mean age, 42.4 ± 10.5 years) were treated with as out-patients. The volume of the treated cysts was calculated with periodic noncontrast enhanced CT examinations 3, 6 and 9, months after the procedure. The procedure was considered successful at follow-up CT when there was total ablation or greater than 80% reduction of size with resolution of symptoms, respectively. Failure was defined as less than 80% reduction and/or persistent symptoms. Results: The sclerotherapy was technically successful in all patients. The diameter of the cysts ranged between 5.5 and 13.5 cm (mean, 8.8 ± 1.4 cm), and 1.5 and 3.8 cm (mean, 2.1 ± 0.4 cm) before and after sclerotherapy, respectively (P < 0.001). Average diameter reduction was 83.7% during the follow-up period. The mean follow- up lasted 7.1 months (3–11 months). Flank pain resolved in 86 of 92 symptomatic patients (93.48%). In six patients, the symptoms decreased slightly. The procedure was successful in 98 of 100 cysts (98%), demonstrated by follow-up CT. The only two failed cyst was larger than 10 cm in diameter and don’t required any further treatment. We did not observe any procedure related complications. Conclusion: Ultrasound guided percutaneous sclerotherapy with NBCA and iodized oil mixture for management of symptomatic simple renal cysts was found to be a real time, effective, safe, well tolerated, alternative and simple technique that can be carried out by urologists as an outpatient procedure.

    Aneurysmal bone cyst (ABC) is a pediatric osseous tumor characterized by extensive destruction of the surrounding bone. The molecular mechanisms underlying its pathogenesis are completely unknown. Recent work showed that translocation of the TRE17/USP6 locus occurs in over 60% of ABC cases resulting in TRE17 overexpression. Immature osteoblasts are presumed to be the cell type harboring translocation of TRE17 in at least a subset of ABCs. However, the effects of TRE17 overexpression on transformation and osteoblast function are unknown. TRE17 encodes a ubiquitin-specific protease (USP) and a TBC (TRE2-Bub2-Cdc16) domain that promotes activation of the Arf6 GTPase. Here we report that TRE17 potently inhibits the maturation of MC3T3 pre-osteoblasts in a USP-dependent and Arf6-independent manner. Notably, we find that TRE17 function is mediated through an autocrine mechanism. Transcriptome analysis of TRE17-expressing cells reveals dysregulation of several pathways with established roles in osteoblast maturation. In particular, signaling through the bone morphogenetic protein (BMP) pathway, a key regulator of osteogenesis, is profoundly altered. TRE17 simultaneously inhibits the expression of BMP-4 while augmenting the BMP antagonist, Gremlin-1. Osteoblastic maturation is restored in TRE17-expressing cells by the addition of exogenous BMP-4, thus establishing a functional role for BMP-4 during TRE17-induced transformation. Because bone homeostasis involves a precise balance between the activities of osteoblasts and osteoclasts, our studies raise the possibility that attenuated osteoblast maturation caused by TRE17 overexpression may contribute to the bone loss/destruction observed in ABC.

    We report the case of an 84-year-old woman who came to our attention with right palpebral edema associated with pain in the omolateral fronto-orbital region. The patient underwent an MRI scan that revealed a rounded, extracerebral intradiploic cystic lesion with dyshomogeneous signal intensity. Computed tomography (CT) imaging was also performed with reformatted 3D reconstruction. Post-surgical histologic analysis confirmed the diagnosis of intradiploic dermoid cyst. We here report the case and discuss epidemiology, imaging features and work-up of this pathological entity. PMID:26915898

    We present the case of a 46-year-old woman with no significant past medical history who developed left mid-thigh pain and fullness. Imaging demonstrated a mineralized soft-tissue mass, which increased in size during a year of monitoring, but retained a circumscribed appearance. The mass was located in the medial soft tissues of the thigh, separate from the bone on imaging studies, and this finding was confirmed during excision. The mass showed gross and microscopic features of an aneurysmal bone cyst. This diagnosis was supported by cytogenetic analysis revealing a t(17;17)(p13;q21) translocation corresponding to the USP6 and COL1A1 loci. Soft-tissue aneurysmal bone cyst is a rare entity, with fewer than 25 reports in the literature. Limited cytogenetic information about these tumors is available. To our knowledge, the USP6 and COL1A1 rearrangement has only previously been described in a pediatric soft-tissue aneurysmal bone cyst. We also discuss the differential diagnosis of ossifying soft-tissue lesions. PMID:26142538

    The simultaneous occurrence of an aneurysmal bone cyst (ABC) on a zygomatic arch with bilateral inferior turbinate gasification is extremely rare, and no previous studies are available. Here we report the case of a 34-year-old Chinese Han female who presented with hyperplasia of the left maxillary bone for one and a half years. The patient was observed to have an ABC on the left zygomatic arch concomitant with bilateral inferior turbinate gasification, as indicated by X-ray computed tomography, contrast-enhanced computed tomography and three-dimensional maxillofacial reconstruction. The patient underwent surgical resection of the cyst, and no postoperative symptoms were observed during the 4 years of follow-up. The etiology of this case is considered to be associated with a gene abnormality.

    Uremic osteodystrophy is an expected complication in subjects with chronic renal insufficiency. It develops gradually and progressively already during the conservative treatment and then during the dialysis treatment. It can present a wide histopathological spectrum including typical alterations (from osteitis fibrosa to osteomalacia and/or mixed lesions) or, more rarely, isolated bone lesions indicative of a brown tumor of the bone. These conditions must be clearly identified in the pretransplant phase, especially if a bone lesion indicative of a pathological condition possibly evolving into a neoplasm is detected fortuitously. We report the case of a 19-yr-old boy with renal insufficiency and candidate for a pre-emptive renal transplantation from a living donor, in whom the diagnosis of ABC of the pubic symphysis - asymptomatic and fortuitously detected while performing instrumental investigations - was suspected through the imaging studies (CT scan, MRI) and was confirmed by the histological examination. This made it possible to perform the renal transplant. The immunosuppressive treatment, which was subsequently administered, was based on steroids, calcineurin inhibitors (tacrolimus), and mycophenolate and did not determine any modification in the radiological aspect of the bone lesion, even after more than one yr from the transplant.

    Fractures are a very important issue in a child’s orthopedic pathology. Neglected a good amount of time, being considered “not too serious”, or “rare”, having better and faster healing methods and not leaving sequels, like in the case of adults, a child’s fractures remain an important chapter of traumatology in general. Because of the raising prevalence of child osteoarticular traumas, as well as new less invasive treatment methods, this theme is always to date. The paper analyzes particular cases of bone fractures that appeared due to minor traumas, on bones with a high brittleness, localized especially on the long bones. Although these fractures on a pathological bone can be seen at all levels of the human skeleton, this paper focuses on fractures located in the proximal third part of the femur. A group of children admitted in the Pediatric Orthopedic Department of “M.S. Curie” Hospital-Bucharest with this diagnostic, were analyzed between 2009 and 2013. PMID:26664486

    PLO-SL (polycystic lipomembranous osteodysplasia with sclerosing leukoencephalopathy) is a recessively inherited disorder characterized by systemic bone cysts and progressive presenile frontal-lobe dementia, resulting in death at <50 years of age. Since the 1960s, approximately 160 cases have been reported, mainly in Japan and Finland. The pathogenesis of the disease is unknown. In this article, we report the assignment of the locus for PLO-SL, by random genome screening using a modification of the haplotype-sharing method, in patients from a genetically isolated population. By screening five patient samples from 2 Finnish families, followed by linkage analysis of 12 Finnish families, 3 Swedish families, and 1 Norwegian family, we were able to assign the PLO-SL locus to a 9-cM interval between markers D19S191 and D19S420 on chromosome 19q13. The critical region was further restricted, to approximately 1.8 Mb, by linkage-disequilibrium analysis of the Finnish families. According to the haplotype analysis, one Swedish and one Norwegian PLO-SL family are not linked to the chromosome 19 locus, suggesting that PLO-SL is a heterogeneous disease. In this chromosomal region, one potential candidate gene for PLO-SL, the gene encoding amyloid precursor-like protein 1, was analyzed, but no mutations were detected in the coding region.

    USP6 rearrangement is the most common genetic abnormality in primary aneurysmal bone cyst, and SS18 rearrangement has not been previously described in any type of tumor where synovial sarcoma was excluded from the differential diagnosis. We report a case of solid aneurysmal bone cyst in which fluorescence in situ hybridization (FISH) analysis indicated rearrangements of both USP6 and SS18, but histologic features were consistent with aneurysmal bone cyst throughout the lesion. Reverse-transcription polymerase chain reaction (RT-PCR) for the SS18-SSX1 and SS18-SSX2 translocations, identity testing, and SS18 FISH were performed on cytogenetic monolayer cultures and formalin-fixed paraffin-embedded (FFPE) tissue. Genomic microarray, FISH, and immunohistochemistry were performed on follow-up studies of the FFPE specimen. The karyotype was 45,X,add(X)(p11.2),add(4)(q13),add(8)(p21),-13,add(17)(p11.2),add(18)(q11.2) in all 20 cells analyzed from monolayer cultures. The karyotype showed no cytogenetically visible alterations of chromosomal regions harboring known partners for USP6. Metaphase FISH with a commercial SS18 break-apart probe showed translocation of the 5' portion of the SS18 probe to the short arm of the derivative X, as is observed in synovial sarcoma. RT-PCR showed no evidence of a SS18-SSX fusion, and immunohistochemistry was negative for TLE1, EMA, and cytokeratin AE1/3 expression. FISH on FFPE sections with a custom break-apart probe flanking USP6 showed evidence for a USP6 rearrangement throughout the tumor (25-50%). FISH on FFPE sections with a commercial SS18 break-apart FISH probe showed more variable results (0-50% split signals). There was no evidence of a SS18-USP6 fusion by FISH or RT-PCR. A molecular inversion probe array revealed a deletion encompassing the entire SS18 gene and its promoter, as well as portions of the region targeted by the commercial SS18 FISH probe. In conclusion, results obtained from commercially available FISH probes may occasionally yield misleading results. In this case, the SS18 rearrangement by FISH resulted from a complex rearrangement of 18q11.2 with a deletion of the SS18 gene. The translocation partner for USP6 remains unknown in this case.

    2014-01-01

    Rathke's cleft cysts are benign sellar and suprasellar lesions arising from epithelial remnants of Rathke's pouch with a peak incidence at 30-50 years of age. The majority are between 10 and 20mm in diameter and contain mucoid or gelatinous material encapsulated in a thin cyst wall of simple or pseudostratified cuboidal or columnar epithelium. Symptomatic cases are rare, but incidental lesions are found in 11% of unselected postmortem cases. The pathogenesis of these lesions is uncertain, but they may occasionally share histopathologic features with (papillary) craniopharyngiomas. The most common presenting symptoms include headaches, visual disturbance, and pituitary hormone abnormalities. MRI reveals well-demarcated homogenous lesions with variable intensity that is highly dependent on cyst contents, which can range from clear, CSF-like fluid to thick, mucoid material. Treatment is almost invariably surgical with the aim of draining the cyst contents and removing the surrounding capsule. The recurrence rate is uncertain due to a lack of studies with long follow-up periods, but risk factors associated with increased likelihood of recurrence include cyst size, presence of squamous metaplasia of the cyst wall, incomplete resection or intraoperative CSF leak, and the need for an abdominal fat graft or sellar packing.

    Nonodontogenic cysts within the jaws are not a common presentation in the pediatric population. Cysts within the pediatric population tend to be developmental and odontogenic in nature. Although nonodontogenic cysts of the jaws are relatively uncommon, it is imperative the clinician understand their clinical behavior and management because failure to do so can result in increased patient morbidity. The nonodontogenic cysts of the jaws that are most often encountered are the central giant cell granuloma, traumatic bone cavity, aneurysmal bone cyst, nasopalatine duct cyst, and nasolabial cyst. This article reviews common clinical findings, radiographic features, histopathologic features, and current treatments of nonodontogenic cysts. PMID:26614699

    2015-04-01

    The development of cell based advanced therapeutic medicinal products (ATMPs) for bone repair has been expected to revolutionize the health care system for the clinical treatment of bone defects. Despite this great promise, the clinical outcomes of the few cell based ATMPs that have been translated into clinical treatments have been far from impressive. In part, the clinical outcomes have been hampered because of the simplicity of the first wave of products. In response the field has set-out and amassed a plethora of complexities to alleviate the simplicity induced limitations. Many of these potential second wave products have remained "stuck" in the development pipeline. This is due to a number of reasons including the lack of a regulatory framework that has been evolving in the last years and the shortage of enabling technologies for industrial manufacturing to deal with these novel complexities. In this review, we reflect on the current ATMPs and give special attention to novel approaches that are able to provide complexity to ATMPs in a straightforward manner. Moreover, we discuss the potential tools able to produce or predict 'goldilocks' ATMPs, which are neither too simple nor too complex. PMID:25451134

    A dentigerous cyst is an odontogenic lesion caused by the expansion of the follicle surrounding the crown of impacted, embedded or unerupted teeth. These cysts may cause destruction of the bone, displacement of adjacent teeth, resorption of their roots and prevent the eruption of cyst-associated permanent teeth. This paper discusses successful use of marsupialization combined with orthodontic treatment to treat cyst-associated impacted permanent teeth and to correct a class II open bite malocclusion.

    Sacral bone remodeling with abnormal dilatation of intervertebral foramina is usually associated with Tarlov's perineurial cysts but can also be caused by slow-growth lesions. In this case report, an atypical inflammatory sacral cyst with bone scalloping was found and some possible causes are suggested. A 77-year-old woman complained of severe back pain and claudication with anal tone weakness. A plain roentgenogram and CT showed spinal canal expansion and characteristic border scalloping of the sacrum. MRI showed septated cystic content with peripheral enhancement. Laminectomy was performed. The cyst contained yellowish viscous material that was easily removed. The neurological symptoms improved after surgery. The cystic wall was composed of dense fibrous tissue without epithelial cell lining; the cystic content was, on histology, inflammatory cells including neutrophils and lymphocytes. Patients who have sacral intraspinal cysts should be identified before doing the treatment such as acupuncture and epidural steroid injection to avoid infection to those cysts. PMID:26662739

    Medical experts are still at issue over the most suitable management of simple neonatal ovarian cysts exceeding 40mm and complex cysts of any size. The authors present surgical treatment of these cysts by classical laparotomy and laparoscopy. The study included 13 newborn babies surgically treated for 6 simple and 7 complex ovarian cysts. The diameter of the cysts ranged from 29 to 102mm. The age of children was from 2 days to 10 months. The open classical laparotomic approach was performed in 8 babies. In the laparotomy group, cystectomy was done in 3 infants with simple cysts. The other 5, presented with ovarian torsion, required salpingo-oophorectomy. Video-assisted cystectomy was the procedure for 3 simplex and one complex cyst with torsion. Laparoscopic adnexectomy was applied in one case with auto-amputated cyst. Our small study demonstrates that laparoscopy is as safe and effective as classical laparotomy in managing neonatal ovarian cysts, but with better cosmetic results. PMID:21970071

    An apparent causal association between crizotinib treatment and renal cyst development emerged during clinical trials in anaplastic lymphoma kinase (ALK)-positive non–small cell lung cancer (NSCLC). Serious adverse event (SAE) reports of renal cysts from a safety database of 1375 patients from four clinical trials were reviewed. A blinded, retrospective, independent radiologic review (IRR) was performed using scans from patients on study for ?6 months in three clinical trials; risk factors for renal cyst development were assessed. Among 17 patients with renal cysts reported as SAEs, evidence of invasion into adjacent structures was noted in seven patients, with no evidence of malignancy found. These patients generally did not require dose reductions, none required permanent crizotinib discontinuation due to this AE, and most continued treatment with clinical benefit. In the blinded IRR, among 255 crizotinib-treated patients, 22%, 3%, and 2% had preexisting simple cysts, complex cysts, or both, respectively. At the 6-month tumor assessment, 9% of all patients had acquired new cysts, and 2% of patients with preexisting cysts had developed new cysts and enlargements (>50%) of preexisting simple cysts. Asians appeared to have an increased risk of developing new cysts on treatment; Koreans in particular had 5.18 times higher odds of developing cysts than non-Asians (95% confidence interval, 1.51–17.78; P = 0.05). Crizotinib treatment appears to be associated with an increased risk of development and progression of renal cysts in patients with ALK-positive NSCLC. While close monitoring is recommended, dosing modification was not generally necessary, allowing patients to remain on crizotinib treatment. PMID:25756473

    For over a century, the arched trabecular patterns of the human proximal femur have been considered to resemble tension and compression stress trajectories produced by stereotypical bending loads. This reflects conventional modeling of the human femoral neck-head region as a short cantilevered beam. Although this conception is the foundation of many biomechanical, clinical, paleontological, and comparative morphological studies of trabecular bone in various species, attempts have not been made to contrast these data to a bone that could be considered a 'control' for simple/stereotypical bending. We quantified trabecular architectural characteristics in sheep and deer calcanei as a first step in potentially establishing them as 'controls' in this context because they have arched trabecular patterns that resemble tension/compression stress trajectories, and have been shown by strain gauge measurements to be relatively simply loaded in bending. Using micro-computed tomography, calcanei from adult domesticated sheep and wild deer were analyzed where in the dorsal 'compression' and plantar 'tension' trabecular tracts they begin to separate and bending is less complex (mid-shaft), and where trabeculae extensively interconnect and loading is more complex (distal shaft). Of the eight trabecular architectural characteristics evaluated, only one (trabecular number, Tb.N) showed a probable mechanically relevant dorsal/plantar difference. However, this was paradoxically opposite in the sheep calcanei. Aside from Tb.N, the architectural characteristics showed little, if any, evidence of habitual bending. The non-uniformity of the stresses between the trabecular tracts in these bones might be reduced by load-sharing functions of their robust cortices and the nearby ligament and tendon, which might account for the similar morphologies between the tracts. These findings may help to explain why in many cases regional trabecular architectural variations seem to lack sufficient sensitivity and specificity for interpreting habitual bending in other bone regions. This cautions against simple interpretations of trabecular bone adaptation in the anthropoid femoral neck. PMID:23481347

    The authors report 10 cases of ante-natally diagnosed ovarian cysts. Ultrasonography greatly contributed to the diagnosis of this condition rarely described before. These cysts are usually follicular cysts. Physiopathological explanation still remain unclear: excessive fetal gonadotrope activity, enzymatic abnormality of the theca interna, abnormal stimulation by the mother's HCG are the main hypothesis. Ultrasonographic prenatal diagnosis is based on the discovery of an intra-abdominal round liquid area in a female fetus with normal kidneys and bladder. Obstetrical management is very simple: observation and vaginal delivery. After birth, diagnosis is assessed by clinical examination and ultrasonography which may be able to recognize a possible torsion (intracystic fluid septation). Treatment is conditioned by two facts: first these cysts are usually follicular benign lesions, second there is a high risk of complications, mainly torsion or rupture. Non-operative treatment and observation can be justified for very small cysts which have low risk of torsion. Laparotomy confirms the diagnosis: regarding non complicated cysts, surgery must be as conservative as possible: cystectomy is often feasible, leaving a laminated but functional ovary. Percutaneous puncture under ultrasonography could be considered. PMID:3533290

    Among all the possible complications of aesthetic rhinoplasty, a rare one is the development of cystic masses on the nasal dorsum: several theories suggest that cysts develop commonly by entrapment of nasal mucosa in the subcutaneous space, but they can also originate from foreign body reactions. This report deals with two cases of nasal dorsum cysts with different pathogenesis: both patients had undergone aesthetic rhinoplasty in the past (26 years ago and 14 years ago, resp.). Both cystic masses were removed via a direct open approach and nasal reconstruction was performed successfully with autologous vomer bone. The pathologic investigations showed a foreign body inclusion cyst associated with latex rubber in the first case and a sequestration of a mucosal-lined nasal bone was not removed at the time of primary rhinoplasty in the second case. A brief review of the literature focuses on the pathophysiology and treatment options for nasal dorsal cysts following aesthetic rhinoplasty. PMID:25276458

The incidental detection of adrenal cysts nowadays has become more frequent as a result of the increase usage of high quality imaging modalities. Adrenal cysts originate from the adrenal gland and can be classified into either true or pseudocyst. Presentation of Case. In this report, we described an adrenal cyst of endothelial type, in a 30-year-old lady who was mistakenly diagnosed to have a hydatid cyst both clinically and by imaging. Discussion. Although adrenal cysts are uncommon, the incidence rate is increasing with the frequent use of various high quality radiological technologies. Adrenal cyst should be considered in the differential diagnosis when dealing with upper abdominal cysts. The size of the adrenal cyst can vary from a few millimeters up to 50 cm in diameter. Most of the adrenal cysts are unilateral, while 8%–15% of those cysts do present bilaterally. The majority of cases are diagnosed between the 3rd and 5th decades. Conclusion. Although most of the adrenal cysts are benign in nature, surgical excision is advisable especially when the cysts are greater than 5 cm in diameter and in the case of suspecting malignancy.

    Introduction: Echinococcosis is a parasitic and zoonotic disease of animals and humans. The cause is Echinococcus granulosus and occasionally, Echinococcus multilocularis. Hydatid cysts are mostly seen in the liver and lungs, although almost all organs and systemscan be involvement. Hydatid cysts seen with bone involvement comprise approximately 3% of all hydatid cysts. Even if a long period of survey is possible, it is still difficult to eradicate the disease and effect a cure. Case Presentation: In this study, an evaluation was made of a patient referred at Yozgat State Hospital Orthopedics and Traumatology Polyclinic with complaints of pain in her left thigh close to the knee. After examinations of plain radiographs, computerized tomography, magnetic resonance images, and blood parameters, a diagnosis was made of left femoral intramedullary hydatid cyst from excised intraoperative material. Throughout a 6-month follow-up period, there was no recurrence and functional results were good. Conclusions: Based on this report (of a patient presented with an intramedullary cyst in the long bones), the primary bone hydatid cyst disease should be kept in mind and be investigated in the differential diagnosis.

    Much about the etiology, pathophysiology, natural course and optimal treatment of cystic disease of the biliary tree remains under debate. Gastroenterologists, surgeons and radiologists alike still strive to optimize their roles in the management of choledochal cysts. To that end, much has been written about this disease entity, and the purpose of this 3-part review is to organize the available literature and present the various theories currently argued by the experts. In part 2, we explore the details surrounding diagnosis, describing the presentation and imaging of the disease. PMID:20011188

    Rudimentary gallbladder is a rare congenital anomaly. We present a case of an 18-year-old boy who was referred to us for surgical management of choledochal cyst. Clinical assessment and correlation of various investigations raised the possibility of rudimentary gallbladder rather than choledochal cyst. Laparoscopy evaluation confirmed the same and simple removal of the hypoplastic gallbladder cured him of his symptoms. Awareness of rare anomalies of the gallbladder and correlation of various imaging modalities aids in accurate diagnosis, thus avoiding major exploration. PMID:26730099

    Bone marrow stromal cells (MSCs) can be differentiated into neuronal and glial-like cell types under appropriate experimental conditions. However, previously reported methods are complicated and involve the use of toxic reagents. Here, we present a simplified and nontoxic method for efficient conversion of rat MSCs into neurospheres that express the neuroectodermal marker nestin. These neurospheres can proliferate and differentiate into neuron, astrocyte, and oligodendrocyte phenotypes. We thus propose that MSCs are an emerging model cell for the treatment of a variety of neurological diseases.

    The soybean cyst nematode (SCN), Heterodera glycines, causes economically significant damage to soybeans (Glycine max) in many parts of the world. The cysts of this nematode can remain quiescent in soils for many years as a reservoir of infection for future crops. To investigate bacterial communities associated with SCN cysts, cysts were obtained from eight SCN-infested farms in southern Ontario, Canada, and analyzed by culture-dependent and -independent means. Confocal laser scanning microscopy observations of cyst contents revealed a microbial flora located on the cyst exterior, within a polymer plug region and within the cyst. Microscopic counts using 5-(4,6-dichlorotriazine-2-yl)aminofluorescein staining and in situ hybridization (EUB 338) indicated that the cysts contained (2.6 ± 0.5) × 105 bacteria (mean ± standard deviation) with various cellular morphologies. Filamentous fungi were also observed. Live-dead staining indicated that the majority of cyst bacteria were viable. The probe Nile red also bound to the interior polymer, indicating that it is lipid rich in nature. Bacterial community profiles determined by denaturing gradient gel electrophoresis analysis were simple in composition. Bands shared by all eight samples included the actinobacterium genera Actinomadura and Streptomyces. A collection of 290 bacteria were obtained by plating macerated surface-sterilized cysts onto nutrient broth yeast extract agar or on actinomycete medium. These were clustered into groups of siblings by repetitive extragenic palindromic PCR fingerprinting, and representative isolates were tentatively identified on the basis of 16S rRNA gene sequence. Thirty phylotypes were detected, with the collection dominated by Lysobacter and Variovorax spp. This study has revealed the cysts of this important plant pathogen to be rich in a variety of bacteria, some of which could presumably play a role in the ecology of SCN or have potential as biocontrol agents.

    Ganglion cysts are tumor-like lesions in the soft tissues, generated by mucoid degeneration of the joint capsule, tendon or tendon sheaths on the dorsum of hand, wrist and foot. However, an intratendinous origin for a ganglion cyst is extremely rare. During dissection of the popliteal fossa, a cyst of 2.5 cm×2 cm×0.5 cm was observed in the tendon of right semimembranosus, 3.5 cm above the insertion of the muscle. Contrast X-ray revealed the cyst as not communicating with the knee joint or any adjacent bursae. Histopathological examination confirmed the diagnosis of ganglion cyst. PMID:25276481

    Cystic echinococcosis, which is caused by the larval stages of Echinococcus granulosus, results from the presence of one or more massive cysts or hydatids, and can involve any organ, including the liver, lungs, heart, brain, kidneys, and long bones. Muscle hydatidosis is usually secondary in nature, resulting from spread of larval tissue from a primary site after spontaneous or trauma-induced cyst rupture or after release of viable parasite material during invasive treatment procedures. Primary muscle hydatidosis is extremely uncommon, because implantation at this site would require passage through the filters of the liver and lung. Intramuscular hydatid cyst can cause a variety of diagnostic problems, especially in the absence of typical radiologic findings. We present an unusual case of a primary hydatid cyst found in the popliteal fossa of the right knee of a 52-year-old woman, presenting as an enlarging soft-tissue tumor for 6 months associated with pain. The mass initially was diagnosed to be Backer?s cyst by ultrasonography, but later it was confirmed postoperatively through histopathological studies to be due to hydatid disease. In regions where hydatidosis is endemic, hydatid cyst should be included in the differential diagnosis of any unusual muscular mass. PMID:24027387

    Adult human mesenchymal stem cells (hMSCs) are able to differentiate into a range of specific cell types in vitro and in vivo, and thus hold tremendous potential for use in regenerative medicine. Despite this promise, deficient understanding of the mechanisms that regulate their differentiation has precluded their widespread use. Genetic manipulation of hMSCs by introduction of transgenes is an indispensable tool for gaining insight into these mechanisms. Like most primary cultures, hMSCs are difficult to transfect with conventional techniques, and although some viral transduction techniques are highly efficient, the protocols require extensive optimization and contain significant health risks. We were generally unable to achieve high transfection efficiencies with lipofection-based reagents that we found, in contrast to electroporation, adversely affected hMSC proliferation and differentiation. Here we report a simple and reliable electroporation protocol that results in transfection efficiencies up to 90% that are comparable to most viral methods while maintaining hMSC stemness. Most importantly, our protocol does not rely on a specific electroporator with preset programs and unique buffers, and is thus much simpler, cheaper, and easier to optimize. Furthermore, we show sustained transgene expression lasting several weeks that was useful for assessing the effects on hMSC function and in transient expression gene therapy. PMID:18752428

    Although splenic involvement alone in hydatid disease is very rare, spleen is the third most common organ involved in hydatid disease. The rarity of splenic hydatid disease poses a diagnostic challenge for clinicians, particularly in non-endemic areas. As the hydatid cyst can present as a simple cyst without having the classic serological and imaging features, and later can lead to life-threatening complications like anaphylaxis, hydatid disease of spleen should be considered in differential in every patient in endemic areas with cystic lesion of spleen until proved otherwise. The author used the keyword “splenic hydatid cyst” in PubMed and reviewed the scientific literatures published from January 1965 to June 2012. The present review is to accentuate the incidence, classification, clinical and pathophysiological features, differential diagnosis, diagnostic modalities, and treatment choices of hydatid cyst of spleen along with follow-up strategy and newer treatment approaches.

    Background There has been no consensus on the optimal treatment of symptomatic sacral perineural cysts. Most previous reports concerning the management methods were either sporadic case reports or a series of limited cases. This study is to further optimize the management for patients with symptomatic sacral perineural cysts by analyzing the outcomes of a cohort of patients who were treated with different strategies. Methods and Findings We reviewed the outcomes of 15 patients with symptomatic sacral perineural cysts who were managed by three different modalities from 1998 through 2010. Six patients underwent microsurgical cyst fenestration and cyst wall imbrication. Seven patients underwent a modified surgical procedure, during which the cerebrospinal fluid leak aperture was located and repaired. Two patients were treated with medication and physical therapy. Outcomes of the patients were assessed by following up (13 months to 10 years). All of the six patients treated with microsurgical cyst fenestration and cyst wall imbrication experienced complete or substantial relief of their preoperative symptoms. However, the symptoms of one patient reappeared eight months after the operation. Another patient experienced a postoperative cerebrospinal fluid leakage. Six of the seven patients treated with the modified surgical operation experienced complete or substantial resolution of their preoperative symptoms, with only one patient who experienced temporary worsening of his preoperative urine incontinence, which disappeared gradually one month later. No new postoperative neurological deficits, no cerebrospinal fluid leaks and no recurrence were observed in the seven patients. The symptoms of the two patients treated with conservative measures aggravated with time. Conclusions Microsurgical operation should be a treatment consideration in patients with symptomatic sacral perineural cysts. Furthermore, the surgical procedure with partial cyst removal and aperture repair for prevention of cerebrospinal fluid leakage seemed to be more simple and effective. PMID:22768183

    Intrasellar arachnoid cyst is very rare. We report a case of intrasellar arachnoid cyst. A 44-year-old male was admitted for evaluation of his headache and visual disturbance on August 6, 1993. Neurological examination revealed bilateral decreased visual acuity and visual field defect. Endocrinological examination showed panhypopituitarism. Other neurological findings were normal. X-ray film of the skull showed a ballooning dilation of the sella turcica with thinning of the sellar floor. CT scan showed a cystic lesion with CSF-density occupied the sella. After intravenous administration of contrast medium, the cyst showed no enhancement. MRI showed the intrasellar mass had the same characteristics as the surrounding subarachnoid space. Bilateral carotid angiographies demonstrated that the carotid siphons were stretched and displaced laterally, and the A1 portions of the anterior cerebral arteries were raised. We made a diagnosis of intrasellar cystic lesion. On August 18, the sella turcica was opened via the transsphenoidal rhinoseptal approach. The cyst contained CSF-like fluid, and a part of the cyst wall was resected. The cavity was filled with Gelfoam and the sellar floor was repaired with bone flap. Postoperatively, the patient's visual disturbance improved, but diabetis insipidus appeared and required hormonal replacement. The patient was discharged on September 27 with improvement of visual acuity and visual field. Histological examination demonstrated that the cyst wall consisted of thick arachnoidal cells with fibrous connective tissue. The arachnoidal cells with oval nuclei was stained with epithelial membrane antigen. Symptoms, signs and radiological findings of intrasellar arachnoid cyst are similar to those of various sellar lesions including pituitary adenoma, craniopharyngioma, empty sella, Rathke's cleft cyst, epidermoid et al.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:7566427

    There are few reports documenting the presence of melanin or melanocytes in epidermal cysts. One hundred and twenty five epidermal cysts from Indian patients were analyzed for the presence of melanin pigment and their sites were noted. A Masson's Fontana stain and immunohistochemistry for S-100 protein and HMB 45 was performed for localization of melanin and melanocytes within the epidermal cysts. Seventy-nine (63%) of the epidermal cysts showed presence of melanin pigment or melanocytes to a variable extent. Melanin was not present in epidermal cysts occurring along lines of fusion of skin folds during embryonogenesis (e.g., ventral midline, inner canthus, nose, upper lip and in the distal most parts like leg and foot and also scrotum). Ten of the 79 epidermal cysts showed extensive accumulation of melanin pigment and infiltration with melanophages in the cyst wall. Four of these patients gave history of trauma and the follow-up was uneventful in two of them. Pigmentation of epidermal cysts thus follows a definite anatomic pattern and is dependent on the natural skin color. Large amount of pigment accumulation within epidermal cysts occurs after cyst rupture and is not associated with hemochromatosis as was believed in the past. PMID:11801783

    A popliteal cyst, originally called Baker's cyst, is a synovial fluid-filled mass located in the popliteal fossa. The most common synovial popliteal cyst is considered to be a distension of the bursa located beneath the medial head of the gastrocnemius muscle. Usually, in an adult patient, an underlying intra-articular disorder is present. In children, the cyst can be isolated and the knee joint normal. The anatomy, etiopathogenesis, clinical presentation, differential diagnosis, imaging and treatment modalities of the popliteal cyst are presented. The authors try to answer some questions dealing with this condition. Is the cyst isolated, can it be treated as such, is its origin always well-defined and does surgical excision provide a permanent cure? PMID:16362357

    In the present study, we had introduced polyurethane (PU) nanofibers that contain hydroxyapatite (HAp) nanoparticles (NPs) as a result of an electrospinning process. A simple method that does not depend on additional foreign chemicals had been employed to synthesize HAp NPs through the calcination of bovine bones. Typically, a colloidal gel consisting of HAp/PU had been electrospun to form nanofibers. In this communication, physiochemical aspects of prepared nanofibers were characterized by FE-SEM, TEM and TEM-EDS, which confirmed that nanofibers were well-oriented and good dispersion of HAp NPs, over the prepared nanofibers. Parameters, affecting the utilization of the prepared nanofibers in various nano-biotechnological fields have been studied; for instance, the bioactivity of the produced nanofiber mats was investigated while incubating in simulated body fluid (SBF). The results from incubation of nanofibers, indicated that incorporation of HAp strongly activates the precipitation of the apatite-like particles, because of the HAp NPs act as seed, that accelerate crystallization of the biological HAp from the utilized SBF.

    The shape of tissues arises from a subtle interplay between biochemical driving forces, leading to cell growth, division and extracellular matrix formation, and the physical constraints of the surrounding environment, giving rise to mechanical signals for the cells. Despite the inherent complexity of such systems, much can still be learnt by treating tissues that constantly remodel as simple fluids. In this approach, remodelling relaxes all internal stresses except for the pressure which is counterbalanced by the surface stress. Our model is used to investigate how wettable substrates influence the stability of tissue nodules. It turns out for a growing tissue nodule in free space, the model predicts only two states: either the tissue shrinks and disappears, or it keeps growing indefinitely. However, as soon as the tissue wets a substrate, stable equilibrium configurations become possible. Furthermore, by investigating more complex substrate geometries, such as tissue growing at the end of a hollow cylinder, we see features reminiscent of healing processes in long bones, such as the existence of a critical gap size above which healing does not occur. Despite its simplicity, the model may be useful in describing various aspects related to tissue growth, including biofilm formation and cancer metastases. PMID:26018964

    OBJECTIVE: To describe the prevalence and characteristics of pineal cysts found on MRI in children. METHODS: This is a retrospective monocentric study of all brain magnetic resonance imaging (MRI) examinations performed under the same technical conditions for checking the idiopathic nature of short stature (ISS group, n = 116) and for the investigation of central precocious puberty (CPP) over a 3-year period (n = 56). Dimensions, wall and septal thickness, number of locules, signal intensity, and the presence of a solid component were analysed. Ten of 19 cysts were re-evaluated (follow-up interval 4-28 months). The prevalence of the pineal cysts was compared between the two groups using χ2 and Fisher's exact tests, and a significance threshold of p < 0.05. RESULTS: The prevalence of cysts was comparable in the two groups, CPP (10.7%) and ISS (11.2%). Cyst characteristics were similar in the two groups and 74% had thin septations. None of the cysts changed on follow-up. None of the children with pineal cysts exhibited neurological signs. CONCLUSION: Benign pineal cysts are a common finding in young children. High-resolution MRI demonstrates that these cysts are often septated. This pattern is a normal variant and does not require follow-up MR imaging or IV contrast media. PMID:22347985

    Spinal extradural arachnoid cyst (SEAC) is a rare disease and uncommon cause of compressive myelopathy. The etiology remains still unclear. We experienced 2 cases of SEACs and reviewed the cases and previous literatures. A 59-year-old man complained of both leg radiating pain and paresthesia for 4 years. His MRI showed an extradural cyst from T12 to L3 and we performed cyst fenestration and repaired the dural defect with tailored laminectomy. Another 51-year-old female patient visited our clinical with left buttock pain and paresthesia for 3 years. A large extradural cyst was found at T1-L2 level on MRI and a communication between the cyst and subarachnoid space was illustrated by CT-myelography. We performed cyst fenestration with primary repair of dural defect. Both patients' symptoms gradually subsided and follow up images taken 1-2 months postoperatively showed nearly disappeared cysts. There has been no documented recurrence in these two cases so far. Tailored laminotomy with cyst fenestration can be a safe and effective alternative choice in treating SEACs compared to traditional complete resection of cyst wall with multi-level laminectomy.

    Intramedullary dermoid cysts are rare tumors, especially those not associated with spinal dysraphism. Only six cases have been reported in the literature. Of these, only two cases have had magnetic resonance imaging studies. We report a case of an 18-year-old female patient, who presented with progressive weakness of both the lower limbs and wasting of both the upper limbs. Magnetic resonance imaging (MRI) showed an intramedullary lesion extending from C3 to D2 with peripheral enhancement on contrast. Decompression of the cystic contents with partial removal of cyst wall was done. Hair with oily cholesterol and keratin debris was encountered. Histopathology confirmed the diagnosis of dermoid cyst. This case adds to the previous reported cases of the rare and uncommon intramedullary space occupying lesions of the spinal cord. PMID:22870157

    Tailgut cysts are congenital lesions that arise from the primitive hindgut in the true embryonic tail but fail to regress during gestation. These lesions are rare and more frequently encountered later in life and more commonly in women, and are the most common primary retrorectal tumor. Tailgut cysts may be asymptomatic or cause rectal bleeding, pain, or symptoms related to mass effect on the rectum or bladder. Pathologically, tailgut cysts are typically multilocular, lined with a variety of epithelial cell types, and are most frequently benign. Imaging is the linchpin of diagnosis due risks associated with biopsy. The purpose of this pictorial review is to present the spectrum of imaging findings associated with tailgut cysts on CT and MRI with focus on the use of advanced MRI and diffusion-weighted imaging. We present case examples of tailgut cysts, their CT and MR imaging findings, and diagnostic and management considerations. PMID:26017036

    Hydatid disease is a parasitosis which is created by Echinococcus granulosus. Hydatid cysts most of ten settled in the liver and lungs. Hydatid cyst is rarely seen in retroperitoneal. Sixty-three year-old female patient was admitted to our hospital with complaints of abdominal distention and with back pain in the Abdominal ultrasonography and computed tomography images, on the posterior of the left kidney, in paravertebral area approximately 15 x 10 cm in size septal cystic lesion was observed retroperitoneally. At laparotomy, partial excision of the retroperitoneal cyst was performed and drainage of the cyst pouch was provided by suction drain. Suction drain was removed 5 days after surgery. Histopathological diagnosis is was reported as hydatid cyst. Hydatid disease is a endemic disease in our country and it should be known that has a typical placements. PMID:26470935

    Oculomotor cistern is normal anatomic structure that is like an arachnoid-lined cerebrospinal fluid-filled sleeve, containing oculomotor nerve. We report a case of arachnoid cyst in oculomotor cistern, manifesting as oculomotor nerve palsy. The oblique sagittal MRI, parallel to the oculomotor nerve, showed well-defined and enlarged subarachnoid spaces along the course of oculomotor nerve. Simple fenestration was done with immediate regression of symptom. When a disease develops in oculomotor cistern, precise evaluation with proper MRI sequence should be performed to rule out tumorous condition and prevent injury of the oculomotor nerve.

    Highlights: •We validate a simple and fast method of quantification of in vitro mineralization. •Fluorescently labeled agents can detect calcium deposits in the mineralized matrix of cell cultures. •Fluorescent signals of the probes correlated with Alizarin Red S staining. -- Abstract: Alizarin Red S staining is the standard method to indicate and quantify matrix mineralization during differentiation of osteoblast cultures. KS483 cells are multipotent mouse mesenchymal progenitor cells that can differentiate into chondrocytes, adipocytes and osteoblasts and are a well-characterized model for the study of bone formation. Matrix mineralization is the last step of differentiation of bone cells and is therefore a very important outcome measure in bone research. Fluorescently labelled calcium chelating agents, e.g. BoneTag and OsteoSense, are currently used for in vivo imaging of bone. The aim of the present study was to validate these probes for fast and simple detection and quantification of in vitro matrix mineralization by KS483 cells and thus enabling high-throughput screening experiments. KS483 cells were cultured under osteogenic conditions in the presence of compounds that either stimulate or inhibit osteoblast differentiation and thereby matrix mineralization. After 21 days of differentiation, fluorescence of stained cultures was quantified with a near-infrared imager and compared to Alizarin Red S quantification. Fluorescence of both probes closely correlated to Alizarin Red S staining in both inhibiting and stimulating conditions. In addition, both compounds displayed specificity for mineralized nodules. We therefore conclude that this method of quantification of bone mineralization using fluorescent compounds is a good alternative for the Alizarin Red S staining.

    We present the second case of an enterogenous cyst of the third ventricle. This is a 28-year-old woman who presented with a 2 year history of progressive headaches and memory loss. A cystic lesion of the anterior third ventricle was noted on MRI. The cyst was resected via a transcallosal approach and demonstrated simple cystic morphology lined by ciliated cuboidal epithelium with numerous goblet cells. The presentation was unusual with signs of memory loss presumably due to a mass effect on the fornices. Although uncommon, this entity should be considered in the differential diagnosis of a cystic lesion of the third ventricle. PMID:23602490

    Epidermoid cysts of the temporal bone are extremely rare and such lesions arising in isolation within the mastoid bone have never been reported in literature. We report and describe the first two unique cases of primary epidermoid cysts arising in the mastoid bone. Of the two cases, one presented with progressive headache and imbalance and the other with unilateral hearing loss and tinnitus. Both cases needed CT and MRI scans and needed surgical management. We review the clinical presentations, histology, pathogenesis, radiological findings and management of these challenging cases. The diagnosis of an epidermoid cyst is based on clinical presentation, physical examination and especially the radiological, histological and intraoperative findings. Total removal of the lesion along with its capsule is recommended to prevent recurrence and to allow for a good long-term prognosis. PMID:25958160

    A review of the English literature reveals a total of 1,337 patients with choledochal cysts. Improved diagnostic techniques to visualize the biliary system are demonstrating an increasing number of unsuspected choledochal cysts in adult patients. Either choledochal cysts remain clinically silent until adulthood or may develop in later life. Experience is reported with adult patients having type I, II, III, and IV choledochal cysts. Type I cysts are preferably managed by excision but cyst anatomy may necessitate choledochoenteric drainage. Type II cysts are treated by excision except for those located within the pancreatic portion of the common bile duct. These are best managed by transduodenal cystoduodenostomy. The type III cyst (choledochocele) should be excised carefully, identifying and preserving the common bile and pancreatic ducts. Type IV cysts include a combination of any one of the first three types of cyst plus the presence of intrahepatic cyst or cysts. Treatment of these cysts is dictated by the type and location of the extrahepatic cyst. Since choledochal cysts are being recognized with increased frequency in adults, surgeons need to be aware of the diagnostic and treatment modalities available for each type of biliary cyst.

    Background/Objective: Tarlov cysts or spinal perineurial cysts are uncommon lesions. These are mostly incidental findings on magnetic resonance imaging or myelograms. The objectives of this study were to describe Tarlov cysts of the sacral region as a potential cause for retrograde ejaculations and review available management options. Methods: Case report and literature review. Results: A 28-year-old man presented with back pain and retrograde ejaculations resulting in infertility. After microsurgical excision of large perineurial cysts, back pain resolved, but semen quality showed only marginal improvement. Later, the couple successfully conceived by intrauterine insemination. To the best of our knowledge, this is the first reported case of Tarlov cyst associated with retrograde ejaculation and infertility. Conclusions: Despite being mostly asymptomatic and an incidental finding, Tarlov cyst is an important clinical entity because of its tendency to increase in size with time. Tarlov cysts of the sacral and cauda equina region may be a rare underlying cause in otherwise unexplained retrograde ejaculations and infertility. Microsurgical excision may be a good option in a select group of patients. PMID:19569467

    The bilateral lateral periodontal cyst is a rare nasological entity, which despite clinical and radiological presentation is being diagnosed by histological characteristics. It is asymptomatic in nature and is observed in routine radiography. The aim and objective of this article is to present a rare case of bilateral lateral periodontal cyst in a 14-year-old child. The clinical and radiographical findings, along with its management have been discussed. Enucleation of bilateral cyst without extraction of the adjacent tooth was performed. Lesion samples were sent for histopathological analysis. The histopathological analysis revealed a thin, non keratinised stratified squamous epithelium resembling reduced enamel epithelium. Epithelial plaques were also seen. A clinicopathological correlation incorporating the surgical, radiographical and gold standard histopathological findings was obtained to suggest the final diagnosis of the bilateral lateral periodontal cyst.

    INTRODUCTION Splenic cyst during pregnancy is rare and may result in spontaneous rupture during the third trimester, which increases perinatal morality. PRESENTATION OF CASE We present a 27-year-old healthy Caucasian female who presented at 18 weeks gestation with left flank pain, early satiety and weight loss. Imaging studies demonstrated a large complex multiloculated splenic cyst. The patient underwent a successful laparoscopic splenectomy and delivered a healthy child at term without complication. DISCUSSION Spontaneous rupture of a splenic cyst during the third trimester incurs a perinatal mortality rate as high as 70%. Surgical management includes open or laparoscopic splenectomy or fenestration and preservation of the spleen. CONCLUSION Laparoscopic splenectomy during the second trimester appears to be safe and offers definitive management of a large symptomatic splenic cyst during pregnancy. PMID:24794024

  18. An unusual presentation of an intraosseous epidermoid cyst of the anterior maxilla: a case report

    2014-01-01

    Introduction Intraosseous epidermoid inclusion cysts are rare benign epithelial inclusion cysts in the bone. They are usually found in the cranium and hand phalanges. They are slow growing lesions, and it is difficult to differentiate them from other inflammatory and cystic lesions. Only a few cases of epidermoid inclusion cyst in the jaw have been reported in the literature. This is the fourth case reported as intraosseous epidermoid cyst of the maxilla in the English literature. Case presentation An asymptomatic 59-year-old Caucasian man was referred to our Oral and Maxillofacial Surgery clinic for a unilocular radiolucent area at his anterior maxilla shown on an orthopantomograph. He was scheduled for surgery and underwent cyst extraction surgery. A pathological examination revealed epidermoid cyst. The diagnostic dilemma in this case report in opposition to the presented intraosseous epidermoid cysts in the literature is that there was no trauma history to his upper jaw. Treatment for this cyst is conservative surgical excision and recurrence is uncommon. Conclusions This report presents an unusual case of an intraosseous epidermoid cyst that occurred with no trauma history to the upper jaw. Although only three cases of epidermoid inclusion cyst have been reported in the maxilla, epidermoid inclusion cyst should be considered in the differential diagnosis of radiolucent lesions of the jaws.

    2010-03-01

    Acromioclavicular joint (ACJ) cysts are an uncommon and unusual sequela associated with shoulder pathophysiology. The majority of literature on ACJ cysts consists of individual case reports with no definitive literature review currently available. In addition to a comprehensive literature review, four clinical cases are presented in this report. First described by Craig (1984), a total of 41 cases have been previously reported in the literature. Of these cases, five occurred with the rotator cuff musculature intact. The remaining 36 cases of ACJ cysts occurred in patients with a complete tear/avulsion of the rotator cuff. Previous attempts at compiling a complete record of all reported cases have combined several distinct conditions into a single category. This article presents two distinct etiologies for the pathogenesis of ACJ cyst formation. In the presence of an intact rotator cuff, a Type 1 cyst can form superficially and be limited to the ACJ. Following a massive or traumatic tear of the rotator cuff, mechanical instability of the humeral head can cause a deterioration of the inferior acromioclavicular capsule (cuff tear arthropathy) and an overproduction of synovial fluid. Overtime, a "geyser" of fluid can form between the glenohumeral and the ACJ, forming a Type 2 cyst. This differentiation and categorization is essential for appropriate classification and treatment.

    Study Design This was a retrospective study. Purpose To study the surgical outcome of synovial cysts of the lumbar spine through posterior laminectomy in combination with transpedicular screw fixation. Overview of Literature Synovial cysts of the lumbar spine contribute significantly to narrowing of the spinal canal and lateral thecal sac and nerve root compression. Cysts form as a result of arthrotic disruption of the facet joint, leading to degenerative spondylolisthesis in up to 40% of patients. Methods Retrospective data from 6 patients, treated during the period of March 2007 to February 2011, were analyzed. All preoperative and postoperative manifestations, extension/flexion radiographs, magnetic resonance imaging, and computed tomography records were reviewed. All underwent surgery for synovial cysts with excision and decompression combined with posterior fixation. The result of surgery was evaluated with Macnab's classification. An excellent or good outcome was considered as satisfactory. Japanese Orthopedic Association Scale was used for evaluation of back pain. Results All patients included in this study had excellent outcomes as regarding to improvement of all preoperative manifestations and returning to normal daily activities. Only 2 cases developed postoperative transient cerebro-spinal fluid leak and were treated conservatively and improved during the follow up period. Conclusions Although this study included a small number of cases and we could not have statistically significant results, the good outcome of decompression of synovial cysts combined with posterior fixation and fusion encouraged us to recommend this approach for patients with juxtafacet synovial cysts.

    Arachnoid cysts are congenital benign cysts accounting for approximately 1% of all intracranial mass lesions. Uncal herniation due to arachnoid cyst is a rare mode of presentation. It is hypothesized that only tension arachnoid cyst could cause the life-threatening condition that results from a progressive deterioration and worsening of a simple and usually congenital arachnoid cyst, associated with the formation of a "ball valve" at the point of an opening on the cyst wall. To-date only one case of an arachnoid cyst causing Uncal herniation has been reported to the best of our knowledge. We present a rare case of uncal herniation in a 60-year-old lady caused by a giant left temporal arachnoid cyst. She presented to us in emergency room after experiencing headaches since last one week followed by vomiting, seizures, and altered state of consciousness. She was operated immediately and marsupialization of the arachnoid cyst was performed. She showed good recovery. Although arachnoid cyst is a benign slowly growing pathology, it can lead to Uncal herniation as a "tension" arachnoid cyst, possible due to "ball-valve" mechanism. Elective treatment should be considered to prevent progressive significant enlargement of cyst. PMID:22483281

    In this paper we describe a new, rapid and sensitive method to determine plasma cell isotype and clonality in bone marrow using flowcytometry. With the use of a new fixation and permeabilization reagent (Permeafix), which preserves cell structure and morphology, and a monoclonal antibody (Mab) specific for plasma cells (B-B4), it has become possible to specifically select plasma cells and to determine the cytoplasmatic immunoglobulins by flowcytometry. Thirty successive bone marrow aspirates from multiple myeloma patients and patients with MGUS were studied as well as 10 bone marrow samples from patients with reactive plasmacytosis. Each sample was analysed both by immunofluorescence on cytospin smears and FACS analysis. There were no discrepancies between plasma cell isotype as determined by FACS and cytospin. Moreover, FACS analysis was shown to allow detection of very low numbers of plasma cells and to determine whether these plasma cells are mono- or polyclonal. Possible applications are discussed.

    Choroidal fissure cysts are often incidentally discovered. They are usually asymptomatic. The authors report a case of growing and hemorrhagic choroidal fissure cyst which was treated surgically. A 22-year-old female presented with headache. Cranial MRI showed a left-sided choroidal fissure cyst. Follow-up MRI showed that the size of the cyst had increased gradually. Twenty months later, the patient was admitted to our emergency department with severe headache. MRI and CT showed an intracystic hematoma. Although such cysts usually have a benign course without symptoms and progression, they may rarely present with intracystic hemorrhage, enlargement of the cyst and increasing symptomatology.

    Large symptomatic hepatic cysts may warrant surgical management. Traditional multiport laparoscopic technique is typically preferred over open laparotomy, but the use of the single-incision laparoscopic approach for this diagnosis is not well documented. Here, we describe the case of a 68-year-old woman who underwent complete anterior wall fenestration, excision and cauterization of a simple hepatic cyst via a single-incision laparoscopic technique through an incision at the umbilicus. The objective of this case report is to document single-incision laparoscopy as a safe, feasible and cosmetically appealing approach for the management of a large hepatic cyst. PMID:26224889

    As opposed to other odontogenic cysts, the radicular cyst is always produced by intraradicular infection, therefore it is important to eliminate the cause of the inflammation as well. During the healing of the radicular cyst, the infected tooth should be treated by extraction or root canal treatment completed by surgical intervention. The presented case is a 77 year-old male patient with Type II Diabetes, who required oral surgery and endodontic treatment. Despite of the age and diabetes of the patient, the bone regeneration was rapid and complete. Seven months after starting the treatment, the size of the cyst decresed significantly and by 12th month it was perfectly healed. PMID:26731964

We report here a case of multiloculated disseminated perineural or Tarlov cysts (TCs). The primary aim of our study was to (1) provide a comprehensive review of the clinical, imaging and histopathological features of TCs (2) to draw attention to the fact that multiple lumbo-sacral and dorsal TCs can produce nerve injuries and serious movement disturbances (3) to document the usefulness of the magnetic resonance imaging (MRI) and bone scan in noninvasive diagnosis and guiding management in such cases. These cysts are clearly identified by MR and computerized tomography imaging of the lumbosacral spine. However, there are no reports on the scintigraphic findings of TCs in literature. TCs are typically benign, asymptomatic lesions that can simply be monitored. Until date, no consensus exists about the best surgical strategy to be followed for their management. PMID:25191117

    Spontaneous and asymptomatic supraclavicular thoracic duct cysts (lymphoceles ) are rare. Only five cases have been reported so far. They are more common after surgery or trauma and have been reported in the abdomen, mediastinum, pelvis and neck. They must be differentiated from other neck cysts as failure to recognise their attachment may result in the disastrous consequence of chylothorax. A high index of suspicion is necessary, and diagnosis usually can be established by fine-needle aspiration and suitable imaging. This case is reported along with a review of the literature and management options, including that of inadvertent damage to the thoracic duct. PMID:12750920

    The median palatine cyst is a rare benign nonodontogenic lesion that attacks the median palatine suture. There is controversy about its pathogenesis; however, its origin is generally attributed to the enclavement of epithelial remnants within the palatine suture between the 2 lateral maxillary processes during their fusion in the origin of the hard palate. The purpose of this report was to relate a case of a median palatine cyst, discussing the rarity of the lesion, its pathogenesis, and the different modalities that could be used for the correct treatment of this pathologic entity.

We describe a case of osteolytic lesion of the proximal tibia presenting to us 20 years after ACL reconstruction using an autologous bone-tendon-bone graft. The original graft fixation technique was interference fixation with a metal screw in the tibial and femoral tunnels. A two-stage revision reconstruction of the ACL was undertaken with curettage and bone grafting of the tibial lesion in the first stage and reconstruction using a four-strand hamstring tendon in the second stage. The patient recovered satisfactorily with complete healing of the cyst and returned to pre-injury level of activities. We have reviewed case reports and case series that describe the aetiology of intra-osseous cyst formation following ACL reconstruction. PMID:26673117

    Purpose: The incidence of painful bone metastases increases with longer survival times. Although external beam radiation therapy (EBRT) is an effective palliative treatment, it often requires several days from the start of treatment to produce a measurable reduction in pain scores and a qualitative amelioration of patient pain levels. Meanwhile, the use of analgesics remains the best approach early on in the treatment course. We investigated the role of radiation therapists as key personnel for collecting daily pain scores to supplement assessments by physician and oncology nursing staff and manage pain more effectively during radiation treatment. Methods and Materials: Daily pain scores were obtained by the radiation therapists for 89 patients undertaking a total of 124 courses of EBRT for bone metastases and compared with pretreatment pain scores. The majority of patients (71%) were treated to 30 Gy (range, 20-37.5) in 10 fractions (range, 8-15 fractions). Results: One hundred nineteen treatment courses (96%) were completed. Pain scores declined rapidly to 37.5%, 50%, and 75% of the pretreatment levels by Days 2, 4, and 10, respectively. Pain was improved in 91% of patients with only 4% of worse pain at the end of treatment. Improved pain scores were maintained in 83% of patients at 1-month follow-up, but in 35% of them, the pain was worse than at the end of treatment. Conclusions: Collection of daily pain scores by radiation therapists was associated with an effective reduction in pain scores early on during EBRT of painful osseous metastases.

    Cyclophosphamide derivatives for in vitro use, such as mafosphamide L lysine (ASTA-Z 7654) are capable of removing residual leukaemic cells from the bone marrow used for autologous transplantation. ASTA-Z also removes committed stem cells detected in semi-solid cultures (CFU-GM). However, haemopoiesis is preserved by more immature progenitors, undetected in usual cultures but detectable in liquid culture of 21 days (MTC). After treating 15 normal bone marrow specimens with 100 microM ASTA-Z, CFU-GM cultures and medium-term cultures (MTC) are carried out. CFU-GM are cultured on the 21st day of incubation from the cell suspension of the MTC. The CFU-GM made the day of in vitro treatment (0.9 colonies/plate) reappear in the CFU-GM cultures performed on the 21st day of incubation of MTC (42 colonies/plate), although the figures attained in parallel controls without any treatment are not fully reached.

    Sacral perineurial (Tarlov) cysts are rare lesions. Over a seven year period 4000 patients underwent surgery for lumbar disk herniation. In three patients neurological symptoms were caused by large sacral perineurial cysts. Methods of choice for diagnosis of Tarlov cysts are lumbosacral magnetic resonance imaging and computerized tomography myelography. The majority of Tarlov cysts are asymptomatic. In case of large (> or = 1.5 cm) and symptomatic perineurial cyst, as in three patients reported in this article, microsurgical treatment was successful. Although rare, perineurial (Tarlov) cysts must be taken into consideration when approaching to patient with low back and radicular pain. Authors review the medical literature, pathological and pathophysiological features and treatment options of sacral perineurial cysts. PMID:20102100

    Laparoscopic surgery has both diagnostic and therapeutic advantages in the management of intra-abdominal cysts in children. Large cysts in small children pose technical challenges during laparoscopic surgery, requiring multiple incisions and advanced laparoscopic skills. This paper describes a novel laparoscopic technique using minimal manipulation for both aspiration and excision of the cyst. This simple, safe, and effective approach was used to achieve traction and facilitate excision of a large intra-abdominal cyst in a neonate and a young child. PMID:26798349

    Pigmented follicular cyst is a rare disorder which typically presents as a pigmented papule on the head or neck and which, histologically, exhibits terminally differentiated, pigmented hair shafts in an epidermoid cyst. We report a 22-year-old man with the multiple variant of this disorder. Clinically he had numerous brown-blue to flesh-coloured, domed-shaped papules, on the anterior chest and abdomen, of 10 years duration. Histologically, hybrid cysts exhibiting trichilemmal and epidermoid keratinization were seen. The cysts contained numerous pigmented, terminally differentiated hair shafts and, embedded in the wall of one cyst, was a sebaceous gland. The condition of multiple pigmented follicular cysts, is thought to represent a distinct subtype within the spectrum of multiple pilosebaceous cystic disorders. PMID:8733387

    A sodium dodecyl (lauryl) sulfate method was evaluated for the preparation of blood specimens and bone marrow aspirates for use in two amplification procedures (Gen-Probe Amplified Mycobacterium Tuberculosis Direct Test [AMTDT] and Roche Amplicor M. avium/M. intracellulare [MAI] Test) for the detection and identification of Mycobacterium tuberculosis and M. avium and M. intracellulare, respectively. The AMTDT is based on amplification of rRNA, whereas the Amplicor MAI Test amplifies a specific DNA region of the 16S rRNA gene. The results of amplification techniques were compared with those of standard culture and culture in BACTEC 13A and BACTEC 12B liquid media. A total of 121 blood specimens and 15 bone marrow aspirates were collected from 136 AIDS patients. Mycobacterial growth was recovered for 103 specimens; 35 yielded M. tuberculosis, 62 yielded M. avium, 5 yielded M. genavense, and 1 yielded M. kansasii. The values of sensitivity and specificity in pretreated specimens for detection of M. tuberculosis by the AMTDT were 94.3 and 100%, respectively, and those for detection of M. avium by the Amplicor MAI Test were 91.9 and 100%, respectively. The simple lysis method described in the present work allows the recovery of mycobacteria from blood specimens and bone marrow aspirates and may be used in combination with the AMTDT and the Amplicor MAI Test to detect and identify different members of the genus Mycobacterium. This method might also be applicable for the identification of mycobacteria from blood culture fluids with acridinium-ester-labeled DNA probes. PMID:9230395

    Summary Osteoporosis is a systemic disease in which the skeletal condition is characterized by a decreased mass of normally mineralized bone, due to an augmentation of bone resorption processes. Bone biomarkers serum are used for the diagnosis. On the other hand the main cause of the resorption in the bone jaws are periodontitis, inflammatory cysts, developmental cysts, odontogenic neoplasms. Periodontal diseases can be localized to a single site of the jaws or can affect all the teeth, with a massive bone resorption. The cysts are classified in developmental and inflammatory. They caused a local bone resorption in the jaws. Keratocystic odontogenic tumor produces a large bone resorption for its local aggressive nature. Their diagnosis is clinical and radiological. The aim of our review is to find a correlation between bone biomarkers serum and periodontitis, inflammatory cists, developmental cysts, odontogenetic neoplasms. The RANK/RANKL/OPG system is the most studied not only in osteoporosis but also in the periodontitis, inflammatory cysts, developmental cysts, odontogenic neoplasms. In the last years osteoimmunology was used to study the periodontal disease progression, because the immunity cells start the bone resorption processes. A lot of studies analyze the biomarkers present in the biofluids, as saliva and gingival crevicular fluid, but not the correlation with serum biomarkers. Future studies must be organized to deepen the correlation between bone biomarkers and bone jaws resorption and to allow diagnosis and prognosis of periodontitis, inflammatory cysts, developmental cysts, odontogenic neoplasms.

    Diffusion rates of numerous trace elements in bone at 20 °C were determined using laser-ablation inductively coupled plasma mass spectrometry analysis of experimentally induced diffusion profiles. Diffusivities are about 1 order of magnitude slower than current semiquantitative geochemical views and about 1.5 orders of magnitude faster than indirect radiotracer estimates. Intrabone volume diffusion is too slow and too similar among many elements to explain trace element profiles in young fossils and archeological materials. Diffusivity differences among elements do, however, explain disparate biokinetic washout of Sr vs. Ba and of light vs. heavy rare earth elements (REEs). These results improve the understanding of the physical principles underlying biokinetic models and rates and mechanisms of trace element alteration of phosphatic tissues in paleontological, archeological, and crystal-chemical contexts. Recrystallization and transport limitations in soils explain trace element profiles in young fossils better than intrabone volume diffusion alone and imply that diffusion of REE and other trivalent cations is likely controlled by a common charge–compensating species rather than ionic radii or partition coefficients.

    Background: The most common benign lesions of the kidney are simple cysts. They are acquired lesions and mostly affect the elderly population. Objectives: To describe the usage of choice-lock catheter and trocar technique in percutaneous renal cyst treatment and determining long-term outcomes. Patients and Methods: This retrospective study was carried out between February 2000 and July 2011. Eighty-eight cysts all of which were Bosniak type-1 cysts were selected in 75 patients. The treatment indications were flank pain, hydronephrosis and hypertension. The choice-lock catheter was used for 84 cysts with the trocar technique. Ninety-five percent ethanol was used as the sclerosing agent. Maximum volume of the injected ethanol was 175 ml. The mean follow-up time after the treatment procedure was 23 months. Sixty-four cysts were located in the cortical and 24 cysts were located at the parapelvic region. Results: Fifty-seven cysts had complete regression, while 31 cysts regressed partially. After the procedure, pain was relieved in 44 (82%) patients and the pain alleviated in four (8%). Normotension was obtained in five (62.5%) of the eight hypertensive patients and no hydronephrosis was detected in nine patients. There were no relationship between the localization and the regression rate. No major complications occurred. Conclusions: Percutaneous ethanol sclerotheraphy in simple cysts is a safe, cost-effective and minimally invasive method. We consider that this technique may be an alternative solution in the percutaneous cyst treatment. PMID:25035702

    The pathogenesis of juxtafacet cysts is closely related to degenerative instability of the lumbar spine and degenerative changes in the ligamentum flavum and the facet joint. A 56-year-old man presented with severe right thigh pain and numbness for 1 month after a laminar fracture of the L4 spine. Magnetic resonance imaging revealed a heterogenous cystic mass surrounding the facet joint between the fourth and fifth lumbar vertebrae on the right side. Conservative therapy was unsuccessful and the lesion was removed by surgical decompression alone without fusion. The histological examination showed a fragmented, cystic wall-like structure composed of myxoid degenerative tissue without lining epithelium. Here we present this case of a ganglion cyst that appeared to be associated with facet joint instability. PMID:23323226

    Intracranial neurenteric cysts are rare congenital lesions that may be mistaken for other cystic neoplastic and nonneoplastic lesions. A 35 years old right handed man presented with a one year history of progressive left hemiparesis, headache, personality changes and seizures. Clinical examination revealed a confused patient with left hemiparesis (power 4/5 in both left upper and lower limbs), upper motor neuron type signs in left half of the body (up going plantar reflex and exaggerated deep tendon reflexes at 3+), left facial weakness of upper motor neuron type. CT scan head with contrast revealed a non-enhancing spherical cystic lesion in the frontotemporoparietal region with minimal to moderate mass effect. The cyst was removed using a combination of hydrodissection and excision. Recovery was complete with no evidence of recurrence or residual disease at 3 months. PMID:25518778

  4. Precocious pseudopuberty due to an autonomous ovarian follicular cyst: case report with a review of literatures

    2013-01-01

    Background Small follicular cysts are commonly found in the ovaries of prepubertal girls, and in most cases, they are of no clinical importance. These cysts are usually self-limiting and resolve spontaneously. However, occasionally, these cysts may enlarge and continue to produce estrogen, resulting in signs of sexual precocity. Here, we report a case of precocious pseudopuberty associated with an autonomous ovarian follicular cyst. Case presentation A 5.9-year-old girl initially presented to a local clinic with vaginal bleeding and a large unilateral ovarian cyst. At 6 months after the initial acute episode, the patient visited our hospital as the ovarian cyst had persisted and increased in size. Endocrinological examination showed elevated estrogen levels and suppressed gonadotropin levels on GnRH stimulation test. Also, no skin pigmentation or bone anomaly was noted. Based on these observations, laparoscopic cystectomy was performed, and histologic analysis confirmed the diagnosis of a follicular cyst. After the laparoscopic cystectomy, the patient’s hormone levels returned to normal and no ovarian cyst was detected by ultrasound. Conclusions As autonomous ovarian cysts are usually self-limiting disorder, no treatment is necessary. Therefore, surgical management should be deferred as long as possible to avoid the risk of repeat surgery, as pseudoprecocious puberty due to autonomous ovarian cysts can resolve spontaneoulsy and frequently recurs. Precocious pseudopuberty with an ovarian cyst may be due to granulosa cell tumor or may be one symptom of the McCune-Albright Syndrome (MAS). A careful longer-term follow up of patients with autonomous ovarian cysts and/or molecular studies may be necessary in such cases. PMID:23937919

    There is still great controversy surrounding the origin of the arachnoid cyst. The most accepted theory in the case of congenital cysts explains how they are formed from an anomalous development of the arachnoid membrane, which is unfolded allowing the accumulation of cerebrospinal fluid inside and creating a cyst. This theory seems to explain the origin of convexity and sylvian cistern arachnoid cysts, whereas those in other locations might be due to other mechanisms. In the anatomopathological analysis, the arachnoid cyst wall can be seen as having few differences from normal, although thickened due to an increase quantity of collagenous material. A description of the embryological development of the arachnoid layer and cyst formation is presented, describing the main anatomopathological findings. PMID:25866380

    Although synovial cysts are most commonly associated with rheumatoid arthritis and osteoarthritis, they may occur in many other conditions. The clinical manifestations of these cysts are numerous and may result from pressure, dissection or acute rupture. Vascular phenomena occur when popliteal cysts compress vessels, and result in venous stasis with subsequent lower extremity edema or thrombophlebitis. Rarely, popliteal cysts may cause arterial compromise with intermittent claudication. Neurological sequelae include pain, paresthesia, sensory loss, and muscle weakness or atrophy. When synovial cysts occur as mass lesions they may mimic popliteal aneurysms or hematomas, adenopathy, tumors or even inguinal hernias. Cutaneous joint fistulas, septic arthritis or osteomyelitis, and spinal cord and bladder compression are examples of other infrequent complications. Awareness of the heterogeneous manifestations of synovial cysts may enable clinicians to avoid unnecessary diagnostic studies and delay in appropriate management. Arthrography remains the definitive diagnostic procedure of choice, although ultrasound testing may be useful. ImagesFig. 1.Fig. 2.Fig. 3. PMID:7233900

    Quantification of Alexandrium cyst fluxes through the Gulf of Maine water column is central to understanding the linkage between the source and fate of annual Alexandrium blooms in the offshore waters. These blooms often lead to paralytic shellfish poisoning (PSP) and extensive closures of shellfish beds. We report here on time-series sediment trap deployments completed at four offshore locations in the gulf between 2005 and 2010 as components of two ECOHAB–GOM field programs. Data presented documents the substantial spatial and temporal fluctuations in Alexandrium fundyense cyst fluxes in the gulf. Cyst delivery out of the euphotic zone peaked primarily between July and August following annual spring–summer Alexandrium blooms and was greatest in the western gulf. At all sites, cyst flux maxima to the subsurface waters were rarely coincident with seasonal peaks in the total mass export of particulate material indicating that cyst delivery was primarily via individually sinking cysts. Where persistent benthic nepheloid layers (BNLs) exist, significant sediment resuspension input of cysts to the near-bottom water column was evidenced by deep cyst fluxes that were up to several orders of magnitude greater than that measured above the BNL. The largest cyst fluxes in the BNL were observed in the eastern gulf, suggesting greater resuspension energy and BNL cyst inventories in this region. Temporal similarities between peak cyst export out of the upper ocean and peak cyst fluxes in the BNL were observed and document the contribution of seasonal, newly formed cysts to the BNL. The data however also suggest that many Alexandrium cells comprising the massive, short-lived blooms do not transition into cysts. Time-series flow measurements and a simple 1D model demonstrate that the BNL cyst fluxes reflect the combined effects of tidal energy-maintained resuspension, deposition, and input of cysts from the overlying water column.

    Background and aims. Pathological fractures are rare in the maxillofacial region and account for less than 2% of all fractures in this site. They are defined as fractures that take place when bone has been weakened by an underlying pathologic process. Among all pathoses, cysts (although so common in the maxillofacial region) constitute a very small part. Here we report a case of a dentigerous cyst in a 38-year-old man.The cyst was associated with a mandibular second premolar tooth and resulted in a pathologic fracture. Excision of the lesion was performed and bony union was observed after 6 months. In the literature review, only one case of dentigerous cyst causing pathologic fracture was found. In addition to the report of the present case, pathologic fractures associated with all types of odontogenic cysts (totally just 12 cases) are reviewed in this article to provide a comprehensive and detailed collection.

    Osteochondroma is a benign bone tumor composed of a bony protrusion with an overlying cartilage cap. Osteochondromas arise in the scapula in 3% to 5% of cases, making them the most common benign bone tumor in this location. Scapular osteochondromas cause various pathologies of the shoulder girdle, including snapping scapula syndrome, chest wall deformity, shoulder impingement, and bursa formation. Bronchogenic cyst is an exceedingly rare finding in the periscapular area. It is a congenital cystic mass lined by tracheobronchial structures and respiratory epithelium. To our knowledge, there are no reports of a contiguous osteochondroma and bronchogenic cyst. A 12-month-old boy presented with an incidentally noted mass on the spine of the scapula, which drained scant, clear fluid through an adjacent pinprick-sized hole. Imaging revealed an exostosis with an adjacent cystic mass. The mass and cyst were excised en bloc, and histopathologic examination confirmed the diagnosis of osteochondroma with contiguous bronchogenic cyst. In this case, we present the report of a novel dual lesion. PMID:26372765

    The classical presentation of choledocal cyst has been regarded as a triad of abdominal pain, jaundice and a palpable abdominal mass; unusual presentations include rupture of the choledocal cyst with bile peritonitis, pancreatitis and bleeding esophageal varices. We are reporting 3 children presenting clinically as recurrent acute pancreatitis with elevated serum amylase and found to have type I choledocal cyst. Despite elevated serum amylase there was no evidence of pancreatic inflammation at laparotomy. High amylase concentration was found in fluid contained within the cyst. This was probably responsible for the elevated serum amylase and also the inflammatory reaction seen in the wall of the choledocal cyst. These cases support the hypothesis that pancreatic reflux into the bile ducts is the etiological factor in the development of choledocal cyst. Our 3 cases were treated by cyst excision and have remained asymptomatic. The presence of hyperamylasemia should not delay appropriate surgical management. The treatment of choice is cyst excision, since it will eliminate factors contributing to the development of cholangitis and hyperamylasemia. PMID:6181241

    The edict to contain costs and meet goals imposed by DRG remuneration policies mandates the work-up of asymptomatic renal mass lesions on an outpatient basis. This proved feasible in 98 per cent of patients. The vast majority of such mass lesions (82 to 90 per cent) is diagnosed with acceptable confidence by computed tomography and sonography alone. For a shrinking group of such patients, yet still 16 to 18 per cent, guided percutaneous aspiration biopsy is necessary to affirm the diagnosis. However, this technique has been refined during recent years to incorporate the use of thin needle equipment and can now be performed on an outpatient basis without significant risk of morbidity. For diagnosing hyperdense inflammatory and infected renal cysts, guided percutaneous aspiration is recommended as the most effective method. This procedure should take precedence over surgical exploration because it can diagnose and provide pertinent bacteriologic information that may determine the course of therapy. In many instances inflammatory cysts or even silent renal abscesses are diagnosed by a percutaneous aspiration technique that is then expanded to serve therapeutic purposes such as percutaneous drainage. Even these procedures can be performed safely on an outpatient basis provided the patient is followed closely. Because complications of percutaneous aspiration procedures are extremely rare, the procedure can be used safely on an outpatient basis. The impact of magnetic resonance imaging on the diagnosis of asymptomatic space-occupying lesions of the kidney is as yet not fully determined; however, this method appears promising for diagnosing some of the refractory lesions such as hemorrhagic cysts, aneurysms, or arteriovenous malformations.

    The objectives of the present study were, first, to establish a methodology for evaluation of the permeability in vitro of hydatid cysts to different drugs and, second, to compare the permeability to albendazole sulfoxide of cysts from untreated animals, cysts from animals treated with 50 mg/kg netobimin for 5 days, and cysts from animals treated with 50 mg/kg netobimin plus 1.1 mg/kg fenbendazole for 5 days. The drug flow follows the Fick law, i.e., the uptake occurs by simple diffusion. We calculated the permeability constant of the cyst membrane by taking into account the disappearance velocity constant, the cyst area, and the incubation solution volume. The permeability value obtained for albendazole sulfoxide was 8.06+/-2.30 x 10(-6) cm s(-1) in cysts from untreated animals, 5.56+/-2.53 x l0(-6) cm s(-1) in cysts from animals treated with netobimin, and 7.05+/-3.04 x 10(-6) cm s(-1) in cysts from animals treated with netobimin +/- fenbendazole. These permeability values show significant differences (P < 0.05). PMID:9610641

    Objective. The aim of this paper is to present an uncommon clinical and radiographic aspect of odontogenic keratocyst (OKC) mimicking paradental cyst. Methods. A 32-year-old female patient showed a well-delimited radiolucent lesion connected with the root of the left third molar with close anatomical relationship with the mandibular canal. The clinical, radiographic, and anamnestic features lead us to diagnose a paradental cyst that was treated by enucleation after extraction of the partially impacted tooth. Results. Histological analysis showed typical histological features of PKC such as the presence of a lining of stratified squamous epithelium with a well-defined basal layer of palisading columnar of cuboidal cells. Conclusion. Initial X-ray analysis and the position of the lesion related to the third mandibular tooth caused us to mistakenly diagnose a paradental cyst. We were only able to identify the cyst as an PKC rather than a paradental cyst after histological analysis. PMID:25114809

    Arachnoid cysts are malformed lesions that contain a fluid similar to the cerebrospinal fluid, and are usually located within the arachnoidal membrane. They represent 1% of all intracranial lesions, and in recent years, with the development of radiological techniques, the clinical detectability of arachnoid cysts seems to have increased. Although the majority of diagnosed arachnoid cysts are located in the cranial cavity and especially in the Sylvian fissure, a small number are located at spinal level and they can occur extra- or intra-spinally. An analysis is carried out, detailing the various tests used for the diagnosis of both intracranial and spinal arachnoids cysts, analysing the indications of each one depending on the location of the cysts and patient age.

    Bone hydatid disease lacks a typical clinical appearance and image characteristics on x ray or CT are similar to those of tuberculosis, metastases and giant cell tumour or bone cysts. However, MRI does show distinctive diagnostic features of bone hydatid disease, especially in the spine. Until recently, treatment of osseous hydatid disease has been entirely surgical. Effective chemotherapy using benzimidazoles, particularly mebendazole, albendazole and combination treatments, has now been achieved in experimental studies and clinical practice. However, most of these drugs are still in the experimental stage or are in the early stages of clinical use. PMID:17675547

    The authors present a series of six patients with large symptomatic benign pineal cysts and review the 27 patients previously reported in the literature. Patients with symptomatic pineal cysts most often present with one of three syndromes: 1) paroxysmal headache with gaze paresis; 2) chronic headache, gaze paresis, papilledema, and hydrocephalus; or 3) pineal apoplexy with acute hydrocephalus. Surgical intervention with radical cyst removal is the treatment of choice for all symptomatic pineal cysts. Complete cyst removal is desirable; however, radical subtotal resection is appropriate if the cyst cannot be easily separated from the quadrigeminal plate. Ventricular shunting should be reserved for patients with persistent hydrocephalus after cyst resection. PMID:1432132

    In Western Siberia (Russia) there are about 100 Artemia lakes with total area over 1 600 km2. Geographically these lakes are located between 51°-56°N and 61°-82°E. In general these lakes are shallow (depth less than 1.5 m), small or medium size (0.1 to 10 km2); they are chloride; their total salinity is from 40 to 250 g/L. The harvesting of cysts per year is only in 20-40 lakes. In Russia 550 tons of dry Artemia cysts (14%-18% of the world production) were harvested annually. This includes about 350 tons in the Altai region and 200 tons in other regions. During our regular 20-year study period the cyst harvest was: 95 tons in Kurgan; 65 tons in Omsk, 20 tons in Novosibirsk, 20 tons in Tyumen. Ways of increasing cyst harvest in Russia are considered in this article. During the last 30 years the harvest of cysts in Russia has increased from 7-20 to 500-600 tons. A significant influence of dryness of the year was found on productivity in selected lakes, but taken for all the lakes together, the relationship was not significant. The optimal salinity for productivity of cysts in the lakes was determined. Analysis of productivity of the lakes and the harvesting results showed that the stocks of cysts are underutilized by approximately 1.7 times.

    Perineurial cysts may be responsible for clinical symptoms and a cure effected by their removal. They do not fill on initial myelography but may fill with Pantopaque some time, days or weeks, after Pantopaque has been instilled into the subarachnoid space. Perineurial cysts arise at the site of the posterior root ganglion. The cyst wall is composed of neural tissue. When initial myelography fails to reveal an adequate cause for the patient's symptoms and signs referable to the caudal nerve roots, then about a millilitre of Pantopaque should be left in the canal for delayed myelography which may later reveal a sacral perineurial cyst or, occasionally, a meningeal cyst. Meningeal diverticula occur proximal to the posterior root ganglia and usually fill on initial myelography. They are in free communication with the subarachnoid space and are rarely in my experience responsible for clinical symptoms. Meningeal diverticula and meningeal cysts appear to represent a continuum. Pantopaque left in the subarachnoid space may convert a meningeal diverticulum into an expanding symptomatic meningeal cyst, as in the case described. Many cases described as perineurial cysts represent abnormally long arachnoidal prolongations over nerve roots or meningeal diverticula. In general, neither of the latter is of pathological significance. Perineurial, like meningeal cysts and diverticula, may be asymptomatic. They should be operated upon only if they produce progressive or disabling symptoms or signs clearly attributable to them. When myelography must be done, and this should be done only as a preliminary to a probable necessary operation, then patient effort should be made to remove the Pantopaque. Images PMID:5531903

    Thoracic duct cysts in the upper portion of the diaphragm are mostly found in the neck and are rarely found in the mediastinum. Thoracic duct cysts should be differentiated from other mediastinal tumors or cysts, and surgical treatment is required to avoid the development of chylothorax if the cyst ruptures. Herein, we report the case of a patient with a thoracic cyst located just above the diaphragm that was treated with surgical resection. PMID:26078934

    The association of choroid plexus cysts with fetal aneuploidy, particularly trisomy 18, was first noted in 1986. Through the years there have been numerous reports on this subject, but no consensus has been reached with regard to chromosomal risk. In this review, we attempt to summarise published reports on second trimester choroid plexus cysts, with an emphasis on the strengths and weaknesses of each report. Based on these reports, additional malformations are a significant risk factor for aneuploidy and an indication for determination of fetal karyotype. The management of isolated choroid plexus cysts remains controversial. PMID:9678699

    Background: Although primary bone tumors are relatively uncommon, they constitute the most important tumors in patients less than 20 years. We aimed to determine the frequencies of primary bone tumors and tumor-like lesions of bone and the anatomical sites of their occurrence. Methods: A retrospective review of histopathology reports of all bone specimens received in a private pathology laboratory in Istanbul between 2009 and 2015. Results: A total of 57 patients (aged 5 to 18 years) with a mean of 13.12 years were studied. Thirty five patients (61.4%) were males and 22 (38.6%) were females. Fifty five (94.4%) of the tumors were benign. Osteochondroma was the commonest tumor accounting for 31 cases (54.3%) followed by osteoid osteoma, 9 cases (15.7%). Chondrosarcoma observed in two patients and Ewing sarcoma in one patient as malignant tumors. Of the 57 bone tumors 13 (22.8%) occurred in the upper extremities, while 44 (77.2%) were in the lower extremities. Proximal humerus was the most commonly involved site in upper extremity tumors, with osteochondromas representing the most frequent type of tumor (4 patients; 7%). In the lower extremities again osteochondromas were the most common type of tumor (8 cases, 14%), with the femur being the most common site of involvement (18 patients, 31.5%). Of the patients with tumor-like lesions; four patients had fibrous dysplasia, 4 patients had non-ossified fibromas, 4 patients had simple bone cysts and 3 had aneurismal bone cyst. Conclusion: This study showed that primary bone tumors were mainly benign, settled predominantly in the lower extremities mostly in the femur with a male preponderance. Osteochondroma was the most common benign bone tumor. We didn’t observed osteosarcoma, which is the most frequent malignant bone tumor. PMID:26617888

    Bile duct injury is one of the known serious complications of laparoscopic fenestration for nonparasitic liver cysts. Herein, we report the case of a huge liver cyst for which we performed laparoscopic fenestration using intraoperative fluorescent cholangiography with indocyanine green. A 71-year-old woman with abdominal distention was referred to our hospital. CT demonstrated a 17?×?11.5-cm simple cyst replacing the right lobe of the liver, so laparoscopic fenestration was performed. Although the biliary duct could not be detected because of compression by the huge cyst, fluorescent cholangiography with indocyanine green through endoscopic naso-biliary drainage tube clearly delineated the intrahepatic bile duct in the remaining cystic wall. The patient had no complications at 3 months after surgery. Fluorescent cholangiography using indocyanine green is a safe and effective procedure to avoid bile duct injury during laparoscopic fenestration, especially in patients with a huge liver cyst.

    We reviewed our experience of hepaticoduodenostomy done for choledochal cyst from 1982 to 2007 at our center. The aim of the study was to evaluate the efficacy of hepaticoduodenostomy as a mode of biliary reconstruction after surgical resection of choledochal cyst, to look for any complications associated with hepaticoduodenostomy, with review of the literature. A total of 56 patients underwent hepaticoduodenostomy after surgical resection of choledochal cyst, of which 54 patients underwent primary cyst excision with hepaticoduodenostomy and 2 patients underwent redo surgery (hepaticoduodenostomy). Most of the patients had an uneventful postoperative recovery. Early complications were biliary leak in three patients which subsided on conservative treatment. Long-term complication was seen in only one patient who developed anastomotic stricture 18 years after primary resection of choledochal cyst and hepaticoduodenostomy. Hepaticoduodenostomy is a relatively safe procedure with very low complication rates. It requires a single anastomosis and is simple to perform. PMID:26730001

    Thyroglossal duct cysts (TDCs) with ambiguous epithelial lining are the most common midline cervical anomaly encountered in children. To histopathologically study the epithelial lining of 32 thyroglossal duct cysts in relation to their locations. A total of 32 cases of thyroglossal duct cysts were collected for this study. The samples were classified into 3 groups as follows: (1) above the hyoid bone; (2) at the level of hyoid bone; (3) below the hyoid bone. All samples were H&E stained. Seventeen TDCs (53 %) were found above the hyoid bone, 6 (18.8 %) were found at the level of hyoid bone and 9 (28.1 %) were found below the hyoid bone. Of the 32 total cases, 6 (18.8 %) were lined with stratified squamous epithelium (SSE), 17 (53 %) were lined with pseudostratified ciliated epithelium (PSCE), 3 (9.4 %) were lined with stratified cuboidal epithelium (SCE), and 6 (18.8 %) exhibited both SSE and PSCE. Pseudostratified ciliated epithelium was dominant in the region superior to the hyoid bone, whereas SCE was detected only in TDCs at the level of hyoid bone. These differences were statistically significant (P = 0.0001). Different types of epithelial lining were detected in the study samples of TDCs. A statistically significant correlation was found between the type of epithelium detected and the location of the TDC at the time of diagnosis. PMID:22968435

    Cleidocranial dysostosis (CCD) is a rare congenital disorder characterized by the heredity, the disturbance of the ossification of the skull and clavicles, and dental anomaly. The entity of CCD was established by Marie and Sainton in 1898. In Japan about 150 cases have been reported since Haneda's first report in 1933. Recently we experienced a rare case of CCD associated with the temporal arachnoid cyst. The patient was a 61-year-old male who had suffered from mild spastic paresis of the left upper extremity since his childhood. One morning he suddenly noticed motor weakness of the left upper and lower extremities and was transferred to our hospital. On admission we observed the left hemiparesis (MMT 3/5), the left central type facial palsy, and the left long tract signs. Physical examination disclosed frontal bossing, depression of the forehead, sloped shoulders, cone-shaped thorax, and thoracic scoliosis. Plain skull radiograph showed persistent metopic suture and frontal fontanelle, many wormian bones around coronal and lambdoid sutures. Plain radiographs of the systemic bones also showed typical features of CCD such as dysplasia of the lateral third of the bilateral clavicles, deformities of the cervical vertebral bodies, thoracic scoliosis, and wide symphysis. CT scan disclosed the right putaminal hemorrhage, the right temporal arachnoid cyst, enlargement of the right middle fossa, thinning of the temporal bone adjacent to the arachnoid cyst. It also showed the atrophy of the right cerebral peduncle and midbrain. Surgical treatment was performed to remove the hematoma and release the cyst. Several neurological disorders associated with CCD have been reported such as epilepsy, mental retardation, spastic paresis etc.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:3437933

    We report the case of a patient with a palpable mass and abdominal pain in the left upper quadrant. A physical examination revealed tenderness in this region. An ultrasound performed initially showed a large cystic structure. A CT examination revealed a large cyst originating in the spleen with loculations in its upper part and focal calcification in the wall. On MRI, the cystic mass showed high signal on T1-weighted and T2-weighted images. The carbohydrate antigen 19-9 (CA 19-9) was measured at 88?U/ml (standard <37.1?mUI/l). According to the imaging examinations and laboratory tests performed, it was impossible to determine if the splenic cyst was parasitic or non-parasitic. Given the most important risks of complications encountered in parasitic cysts, it was decided to treat this splenic cyst as a parasitic cyst. For this reason, an elective laparoscopic splenectomy with preoperative embolisation of the splenic artery was performed. The histological diagnosis was a primary epidermoid splenic cyst with inner lining epithelial cells. PMID:23667225

    We present a cervical thymic cyst in an otherwise healthy 11 year old boy. Ultrasonography revealed a smooth, medium echogenic cystic mass of 62 x 28 x 12 mm with weak acoustic enhancement lying between the carotid artery and the internal jugular vein. The mass extended from the hyoid bone to the inferior pole of the thyroid gland. CT scans also revealed the displacement of the carotid artery and the internal jugular vein by an atypically dense cystic mass. At operation the vagus nerve had to be dissected from the posterior wall of the cyst. A solid band of fibrous tissue extended to the inferior pole of the thyroid gland; there was no connection to the pharyngeal wall. On histological examination Hassal's bodies, cholesterol crystals and a mild round-cell infiltration were observed. The postoperative course was normal. There were no immune defects or signs of lymphogranulomatous disease. Cervical thymic cysts may be recognised before operation and differentiated from second arch cysts by their atypically low infrahyoid position, their intimate relation to the vessels of the neck and their extension into the upper mediastinum. Surgery can be difficult due to the intimate relation to the vessels of the neck and the vagus nerve, and to extension into the upper mediastinum. PMID:1568889

    Cystic lesions of the pancreas can be divided into true cysts, pseudocysts, and cystic neoplasms. Lymphoepithelial cysts (LECs) are a type of true cyst that can mimic pseudocysts and cystic neoplasms. LECs are rare lesions; fewer than 90 cases have been reported in the English language literature. The case of a 60-year-old man with an LEC of the pancreas is reported. He was admitted with upper abdominal discomfort. Computed tomography showed a 64 × 39 mm cystic mass in the retroperitoneum behind the duodenum and inferior caval vein. Magnetic resonance imaging revealed a right-sided mass on T1-weighted imaging, with a clear boundary between the mass and its surroundings, except for the pancreas. The mass had an inhomogeneous intensity on T2-weighted imaging. Within the mass, small floating nodules with low intensity were seen. Endoscopic ultrasound showed many high-echoic nodules and smaller grains scattered everywhere in the mass. Fine needle aspiration and cytologic examination were performed. Characteristic chylaceous fluid was obtained in which anucleate squamous cells were found. There were also a few atypical large cells with irregularly shaped marked nucleoli and degenerative cytoplasm. Cytologic diagnosis was suspicious for malignancy. The lesion was diagnosed as a retroperitoneal cyst, probably of pancreatic origin. Since a neoplastic lesion could not be ruled out, surgery was performed. The lesion was palpable on the dorsal side of the second portion of the duodenum. The mass was completely resected. Macroscopically, the lesion was a multilocular cyst with a thin septal wall. The cyst was filled with cottage cheese-like substance. Microscopically, the cyst wall was composed of stratified squamous epithelium and dense subepithelial lymphatic tissue with developed lymph follicles. The epithelial cells had no atypia. The histopathologic diagnosis was LEC of the pancreas. The patient's postoperative course was good. PMID:23139650

    Laparoscopy in hydatid liver disease, is not addressing only to simple but to complicated cases, although the rate of complications registered a significant decrease because of the modem means (ultrasonography, TC) and the precocity of the diagnostic. We made a retrospective study on 76 patients with liver hydatid cysts admitted and operated in two Surgery Clinics of Sibiu and Braila, between January 2002 and January 2007. On 52 cases we performed laparoscopic interventions and 24 where operated in open surgery, decided by the option and the experience of the surgeon. Our laparoscopic technique is based on specific and original instruments, two patented inventions which increase the security of the primary approach of the liver hydatid cyst. This specific set of instruments, uses extraperitoneal work tunnels for treatment and exploration inside the cyst. The limits of laparoscopy are represented by the cases which presume difficulties and require the conversion. We had one patient who needed conversion to open surgery with a "mercedes" incision, because of the huges dimensions of the liver cyst (25 cm), which did not allowed the induction of a suitable work camera, and because of it's central position (IV-V-VI segments) and numerous adherences to adjacent organs. At three or our cases, the cyst position and the peri-cystic adherences, required the cysto-phrenic dissection, ended with diaphragm perforation, solved by laparoscopic suture without thoracic drainage, but with intra-operatory aspiration of the pneumothorax. The advantages of the laparoscopy are numerous, from the excellent visibility inside abdomen and inside the hydatid cyst cavity, the protection of the abdominal wall and peritoneal cavity, to a relevant shortening of hospitalisation period and convalescence.

The primary aim of this case study was to (1) provide a comprehensive review of the clinical, imaging, and histopathological features of TCs (2) to draw attention to the fact that multiple lumbosacral and dorsal TCs can produce nerve injuries and serious movement disturbances, and (3) to document the usefulness of the magnetic resonance imaging and bone scan in non-invasive diagnosis and guiding management in such cases. These cysts are clearly identified by magnetic resonance imaging (MRI) and computerized tomography imaging of the lumbosacral spine. However, there are no reports on the scintigraphic findings of multilocular disseminated TC in literature. TCs are typically benign, asymptomatic lesions that can simply be monitored. To date, no consensus exists about the best surgical strategy to use when indicated. PMID:23723584

    Hydatid cyst disease is a zoonotic disease caused by Echinococcus granulosus, E.multilocularis or E.Vogli.

    Most of Tarlov or perineurial cysts remain asymptomatic throughout the patient's life. The pathogenesis is still unclear. Hemorrhage has been suggested as one of the possible causes and trauma with resultant hemorrhage into subarachnoid space has been suggested as an origin of these cysts. However, Tarlov cysts related to spontaneous subarachnoid hemorrhage has not been reported. The authors report a case of Tarlov cyst which was symptomatic following spontaneous subarachnoid hemorrhage. PMID:22053232

    Pericardial cysts are most commonly located at the cardiophrenic angle or, rarely, in the posterior or anterior superior mediastinum. The majority of pericardial cysts are asymptomatic and are found incidentally. Symptomatic pericardial cysts present with dyspnoea, chest pain, or persistent cough. We describe four patients with symptomatic pericardial cysts who were treated with either echocardiographically guided percutaneous aspiration or video-assisted thoracoscopic surgery, or both; thoracotomy; or conservative therapy.

    Retrorectal cysts are rare benign lesions in the presacral space which are frequently diagnosed in middle-aged females. We report here our experience with two symptomatic female patients who were diagnosed as having a retrorectal cyst and managed using a laparoscopic approach. The two patients were misdiagnosed as having an ovarian cystic lesion after abdominal ultrasonography. Computer tomography (CT) scan was mandatory to establish the diagnosis. The trocar port site was the same in both patients. An additional left oophorectomy was done for a coexisting ovarian cystic lesion in one patient in the same setting. There was no postoperative morbidity or mortality and the two patients were discharged on the 5th and 6th post operative days, respectively. Our cases show that laparoscopic management of retrorectal cysts is a safe approach. It reduces surgical trauma and offers an excellent tool for perfect visualization of the deep structures in the presacral space. PMID:19030218

    Primary splenic epithelial cyst is an unusual event in everyday surgical practice with about 800 cases reported until date in the English literature. Splenic cysts may be parasitic or non-parasitic in origin. Nonparasitic cysts are either primary or secondary. Primary cysts are also called true, congenital, epidermoid or epithelial cysts. Primary splenic cysts account for 10% of all benign non-parasitic splenic cysts and are the most frequent type of splenic cysts in children. Usually, splenic cysts are asymptomatic and can be found incidentally during imaging techniques or on laprotomy. The symptoms are related to the size of cysts. When they assume large sizes, they may present with fullness in the left abdomen, local or referred pain, symptoms due to compression of adjacent structures (like nausea, vomiting, flatulence, diarrhoea) or rarely thrombocytopenia, and occasionally complications such as infection, rupture and/or haemorrhage. The preoperative diagnosis of primary splenic cysts can be ascertained by ultrasonography (USG), computed tomography or magnetic resonance imaging, although the wide use of USG today has led to an increase in the incidence of splenic cysts by 1%. However, careful histopathological evaluation along with immunostaining for presence of epithelial lining is mandatory to arrive at the diagnosis. The treatment has changed drastically from total splenectomy in the past to splenic preservation methods recently. PMID:25320525

    Although the availability of thyroid cyst fluid is easy by fine-needle aspiration, less is known about the biochemical composition of thyroid cyst fluid. The authors have, therefore, determined the biochemical composition of 18 benign thyroid cyst fluid specimens. They found that the activities of aspartate aminotransferase (AST), lactate dehydrogenase (LDH), and the concentrations of total protein, total bilirubin, and uric acid were highly increased in thyroid cyst fluid specimens when compared with normal human serum specimens. The concentrations of glucose, cholesterol, and triglycerides in cyst fluid were within normal serum limits. Selenium (Se) concentrations in most cyst fluids were low. Moreover, there was no correlation between Se and other biochemical parameters. Protein electrophoresis of cyst fluid specimens yielded high concentrations of alpha 1 and especially alpha 2 globulin fractions indicating an inflammation. The concentrations or activities of biochemical analytes were not significantly different in pure and mixed cysts. Those parameters were also not significantly different between cyst fluids of different colors. The gross appearance of the fluid and the presence of certain biochemical analytes were consistent with a hemorrhagic origin of most of the cyst fluid specimens. However, some biochemical markers indicate that autolysis or necrosis of thyroid tissue may also contribute the composition of thyroid cyst fluid. The reason for lower Se concentration in the thyroid cyst fluid may be the lower Se concentration in the Turkish population. These results also suggest that the fluid color or nature of cyst, e.g., pure or mixed cyst, is not a main determinant of biochemical composition of benign thyroid cyst fluid. PMID:9258464

Symptomatic sacral perineural cysts are uncommon but sometimes require surgical treatment. A 69-year-old male presented with pain in the buttock. He was diagnosed as having a sacral cyst with magnetic resonance imaging. For the nonoperative diagnosis and treatment, caudal peridurography and block were performed. After the treatment, the patient's symptom was relieved. We suggest a caudal peridural block is effective in relieving pain from a sacral cyst. PMID:22787551

    Hydatid cyst is a parasitic infestation caused by Echinococcus granulosus. Lungs are the second most common site of involvement after liver. The diagnosis of complicated pulmonary hydatid cysts may not be easy because hydatid cyst disease mimics tuberculosis, lung cancer, empyema, or abscess. Fiberoptic bronchoscopy can be a valuable tool in the diagnosis of the infestation by visualization of hydatid cyst membrane. Here, we report the case of a 33-year-old woman who presented with hemoptysis and chest discomfort and was diagnosed with a hydatid cyst by fiberoptic bronchoscopy. PMID:26492607

    Epithelial-lined or true cysts of the adrenal gland are exceedingly rare accounting for only 9% of all adrenal cysts. A 55-year-old woman with a medical history for cholecystectomy and liver hydatidosis presented with an 8-month history of abdominal pain in the upper left quadrant. Physical examination was unremarkable and laboratory tests were within normal range. Computed tomography displayed a homogeneous and finely calcified cystic mass of the left adrenal gland measuring 12 x 10 cm. A hydatid cyst of the adrenal gland was suspected preoperatively and the patient underwent uneventful excision of the cyst. Histological examination of the surgical specimen revealed that the cyst wall was lined by cuboidal to flattened cells with bland cytologic features. Immuohistochemically, the cyst lining expressed intensely cytokeratin but was negative for CD 34 and calretinin. The final pathological diagnosis was epithelial adrenal cyst. PMID:22953505

    Esophageal duplication is the second most common site of gastrointestinal duplication and most cases present with complications. These complications include bleeding, infection, dysphagia, and dyspnea. We report an incidental case of a true intramural esophageal duplication cyst in a new military recruit. The patient was diagnosed in Armed Forces Hospital, Oman. The patient came for a pre-recruitment routine check-up, he was found to have a suspicious soft tissue lesion on chest X-ray. He was referred to the thoracic surgeon for further investigations. The investigations included computed tomography and magnetic resonance imaging chest scans, barium swallow, endoscopy and, finally, an endoscopic ultrasound. All workup pointed to a diagnosis of esophageal duplication cyst; therefore, the decision was made to excise the lesion after discussion with the patient about the possible diagnosis and nature of the treatment. The cyst was completely excised thoracoscopically with uneventful recovery. The patient was discharged a few days later and was doing well in subsequent visits to the outpatient department. The histopathological exam confirmed the diagnosis of a true congenital duplication cyst, which was lined by pseudostrati?ed ciliated columnar epithelium overlying double layers of thick bundles of smooth muscle ?bers.

    The aim of this study was to assess the effect of simple renal cysts on extracorporeal shockwave lithotripsy (SWL) in patients with calyceal renal calculi. Patients with simple renal cysts >35?mm and ipsilateral renal calculi <20?mm that were treated with SWL constituted group 1 (cyst + calculi). The control group included patients aged >40 years that had renal calculi <20?mm and no cysts that were treated with SWL. The 2 groups were compared according to age, gender, body mass index, calculi size, localization, and density, the calculi fragmentation rate, and the percentage of stone-free patients. Mean cyst size in group 1 was 44.04 ± 9.08?mm. Mean age in group 1 was 61.4 ± 10.2 years versus 56.9 ± 8.2 years in the control group; the difference was significant (P = 0.045). There were not any other significant differences between the 2 groups, except for the stone-free rate (P > 0.05), which was 33.3% in group 1 and 68.2% in the control group (P = 0.017). The presence of renal cysts in a patient with calculi requires that an individualized treatment plan be devised, so as to provide the patient with the most effective treatment. PMID:23840202

    More precise methods are needed to recover Giardia and Cryptosporidium (oo)cysts from wastewater in order to advance research related to their inactivation, removal, quantification, and species differentiation. This study applied different methods to recover the maximum number of (oo)cysts from wastewater samples using ColorSeed®. Immunomagnetic separation assisted in capturing oocysts mainly in samples with medium and low turbidity. A triple centrifugation method reached recovery rates of 85% and 20%, for Giardia cysts and Cryptosporidium oocysts, respectively, in raw wastewater, and 62.5 and 17.5% in secondary-treated effluent. For low turbidity-treated effluent, membrane filtration reached 67.5% recovery for Giardia cysts and 22.5% for Cryptosporidium oocysts. Simple, quick and low-cost methods do not involve much handling of the samples and could be useful, particularly in developing countries. PMID:26322766

    Purpose Laparoscopy is considered the treatment of choice for hepatic cysts, especially those located in anterolateral segments (AL; segments II, III, IVb, V, and VI) because of the ease of laparoscopic access. Here, we evaluated the feasibility and safety of laparoscopic treatment of hepatic cysts in posterosuperior segments (PS; segments I, IVa, VII, and VIII). Methods We retrospectively analyzed clinical data for 34 patients who underwent laparoscopic treatment of hepatic cysts between September 2004 and December 2012. Patients were divided into two groups depending on whether the main largest cyst was located in AL (n = 20) or PS (n = 14). Laparoscopic cyst unroofing was performed in 29 patients with symptomatic simple cysts. Laparoscopic resection was performed in 5 patients with suspected cystic neoplasms. Results There were no deaths or major complications. The mean operation time was 110 minutes and the mean hospital stay was 4.4 days. The mean cyst size was not significantly different (P = 0.511) but the frequency of multiple cysts was significantly greater in group PS (P = 0.003). The predominant type of resection was unroofing in both groups (P = 0.251). The mean blood loss (P = 0.747), mean hospital stay (P = 0.812), mean operation time (P = 0.669), morbidity rate (P = 0.488), and relapse rate (P = 0.448) were not significantly different. Relapse occurred in one patient who underwent reunroofing 17 months later. The median follow-up is 62 months. Conclusion Laparoscopy is a safe procedure for hepatic cysts located in posterosuperior segments. PMID:24851223

    This case describes a 46-year-old woman with local pelvic and perineal pain, persisting for 2 years at presentation. The pain worsened during the night and morning and was alleviated during daily activities. Low back pain was associated with morning stiffness lasting longer than 2 h. Sometimes, she felt pain and numbness along her left S1 dermatome, without overt bladder or bowel incontinence. Lasegue's sign was negative. Erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) were elevated (35 mm/h and 9.4, respectively) and Mennel's sign was present on both sides, indicating possible inflammation of the sacroiliac joints. However, radiographs of the lumbosacral spine and sacroiliac joints were normal. Magnetic resonance imaging (MRI) revealed a large spinal meningeal cyst in the sacrum (60?×?37?×?22 mm) consisting of multiple perineural cysts. The cyst eroded the surrounding sacral bone structures, narrowed several sacral foramina, and compressed neighboring nerve fibers. MRI findings on sacroiliac and hip joints were normal.

    The identification and quantification of Heterosigma akashiwo cysts in sediments by light microscopy can be difficult due to the small size and morphology of the cysts, which are often indistinguishable from those of other types of algae. Quantitative real-time PCR (qPCR) based assays represent a potentially efficient method for quantifying the abundance of H. akashiwo cysts, although standard curves must be based on cyst DNA rather than on vegetative cell DNA due to differences in gene copy number and DNA extraction yield between these two cell types. Furthermore, qPCR on sediment samples can be complicated by the presence of extracellular DNA debris. To solve these problems, we constructed a cyst-based standard curve and developed a simple method for removing DNA debris from sediment samples. This cyst-based standard curve was compared with a standard curve based on vegetative cells, as vegetative cells may have twice the gene copy number of cysts. To remove DNA debris from the sediment, we developed a simple method involving dilution with distilled water and heating at 75°C. A total of 18 sediment samples were used to evaluate this method. Cyst abundance determined using the qPCR assay without DNA debris removal yielded results up to 51-fold greater than with direct counting. By contrast, a highly significant correlation was observed between cyst abundance determined by direct counting and the qPCR assay in conjunction with DNA debris removal (r2 = 0.72, slope = 1.07, p < 0.001). Therefore, this improved qPCR method should be a powerful tool for the accurate quantification of H. akashiwo cysts in sediment samples. PMID:26741648

    Mesenteric cysts are heterogeneous groups of lesions. Most of them are developmental cysts of lymphatic and enteric origin or cystic neoplasm such as mesothelioma or cystic teratoma. Urogenital cysts are a subcategory of developmental cysts of the mesentery. They are thought to arise from vestigial remnants of urogenital apparatus. These cysts may show evidence of mesonephric or metanephric differentiation. An 11 -year -old boy was presented with undescended testis. During preoperative work- up, an incidental cystic lesion was discovered which was attached to the ileum. Aspiration cytology of the cyst content revealed cuboidal to columnar cells; some of them were ciliated. Histologic examination showed a cyst with fibromuscular wall, lined by Mullerian type ciliated epithelium; so the diagnosis of urogenital mesenteric cyst of Mullerian type was made. Urogenital cysts are rare lesions, but they should be considered in differential diagnosis of any cystic lesion of the mesentery. Cytology could be a useful method for evaluation and revealing the nature of these cysts. PMID:23808784

    Introduction Thyroglossal duct cysts are the most common congenital midline neck swelling in children. Aim To evaluate the clinical features, treatment, incidence of complications and outcomes in children with congenital midline neck lesions and more specifically with thyroglossal duct cyst, treated in our department the last ten years. It is a retrospective study. Materials and Methods The aggregated data revealed 59 patients with congenital midline neck lesions, of which 33 patients were with thyroglossal duct cyst (TDC). The diagnosis of TDC was made by physical examination, ultrasound (US) in all cases, and for complicated cases a magnetic resonance imaging (MRI) was performed. In all cases followed histopathological conformation of thyroglossal duct cyst. Results Fifty nine patients were admitted with midline cystic neck mass and the histopathological evaluation revealed, 33 cases (55.9%) of thyroglossal duct cyst, 14 cases (23.7%) of dermoid cysts, 3 cases (5.1%) of second branchial anomalies, 4 cases (6.7%) of inflammation of unknown cause, 4 cases (6.7%) of lymph nodes and 1 case (1.7%) of capillary skin haemangioma. More specifically, 38 patients were admitted with preoperative diagnosis of thyroglossal duct cyst, but in 5 patients pathological investigation demonstrated the presence of dermoid cyst. The mean age of the 33 patients with TDC at the time of surgery was 6.125 years, ranging between 9 months and 13 years with 10 patients younger than 3 years. Of the 38 patients with initial diagnosis of thyroglossal duct cyst, only four patients (10.5%) had a simple cyst excision and complication rate was 25% (1 case with recurrence). In these patients, the histopathological examination showed that three of them had a dermoid cyst and one had thyroglossal duct cyst. The other 34 patients (89.4%) were treated by Sistrunk’s procedure, with two cases (5.9%) were proven on histology to be non TDC. In this group the complication rate was 3.03% (1 case with wound infection). Conclusion The inappropriate surgical approach due to misdiagnosis or the incomplete surgical procedure remains the impact factor for recurrence. The modification of Sistrunk’s procedure remains the main surgical technique that can provides good results with low rate of complication (3.03%) and recurrence (0%) as shown of our collecting data.

    An epidermoid cyst of the cecum is extremely rare; only eight cases have been reported in the literature. A 63-year-old woman was admitted to Kyung Hee University Medical Center with a colonic mass that had been discovered incidentally during a regular health check-up. The radiographic impression was that this mass was a gastrointestinal stromal tumor. During surgery, an exophytic mass in the cecal wall was resected by using an ileocecectomy. Based on the macroscopic and the microscopic findings, this case was identified as an epidermoid cyst of the cecal wall. We report this case to discuss the origin of this entity and the unusual nature of our case. PMID:25745626

    Sebaceous cyst is an epidermal cyst often found on the hairy areas of the body such as scalp, trunk and face. Though commonly encountered in surgical practice, its presentation as multiple giant sebaceous cysts over scalp is rare. However, in long standing cases malignant transformation has also been sparingly reported. We report a case of a 52-year-old male presenting with multiple large sized swellings on the scalp, seven in number. These were present since childhood and gradually progressed to the enormous size of largest measuring 10cm x 8cm. Excision of these cysts was undertaken and specimens were sent for histopathological examination which confirmed the nature of these cysts to be sebaceous cysts. No malignant changes were reported in any of the specimens. The patient was followed up and was doing well. PMID:26673123

    Radicular cysts are inflammatory odontogenic cysts of tooth bearing areas of the jaws. Most of these lesions involve the apex of offending tooth and appear as well-defined radiolucencies. Owing to its clinical characteristics similar to other more commonly occurring lesions in the oral cavity, differential diagnosis should include dentigerous cyst, ameloblastoma, odontogenic keratocyst, periapical cementoma and Pindborg tumour. The present case report documents a massive radicular cyst crossing the midline of the palate. Based on clinical, radiographical and histopathological findings, the present case was diagnosed as an infected radicular cyst. The clinical characteristics of this cyst could be considered as an interesting and unusual due to its giant nature. The lesion was surgically enucleated along with the extraction of the associated tooth; preservation of all other teeth and vital structures, without any postoperative complications and satisfactory healing, was achieved.

    2014-01-01

    Glandular odontogenic cyst (GOC) is an uncommon developmental odontogenic cyst of jaws with a relative frequency between 0.012 and 1.3%. GOC is very rare and only 111 cases have been documented in the English literature so far. Generally, this cyst is encountered in the anterior areas of the mandible and is more common with a wide age range, the mean age being 49.5 years and has a tendency to recur. GOC is often misdiagnosed because of its overlapping histopathological features with that of other odontogenic cysts such as lateral periodontal cyst (LPC) or botryoid cyst and central low-grade Mucoepidermoid carcinoma. Histopathological diagnosis and differential diagnosis of GOC is challenging for pathologist. Here, we present a case of GOC in a 40 year old male patient in left mandibular region that crossed the midline. PMID:24959044

    Dentigerous cyst is a type of odontogenic cysts and generally occurs in the ages of twenties or thirties. Dentigerous cyst always includes a tooth which cannot complete the eruption process and occurs around the crown by the fluid accumulation between the layers of enamel organ. In rare cases, dentigerous cyst occurs in the first decade of life and develops in an immature permanent tooth as a result of a chronic inflammation of overlying nonvital primary tooth. In this report, a case of dentigerous cyst in primary dentition in a 5-year-old child patient and its treatment were presented. The dentigerous cyst was totally enucleated, and the unerupted permanent first premolar tooth was removed from the primary mandibular right premolar region. There was no recurrence observed after 18 months follow-up.

    Lymphoepithelial cysts are benign, slowly growing unilocular or multilocular lesions that appear in the head and neck. They are also called Branchial cyst. The head and neck sites are the salivary glands(more commonly parotid and rarely submandibular gland) and the oral cavity (usually the floor of the mouth). there are various methods of investigation available today, of which Fine needle aspiration cytology (FNAC) can be used to provide an immediate diagnosis of a lymphoepithelial cyst. The other investigations include, Ultrasonogram,and Computed tomography. It usually occurs due to the process of lymphocyte-induced cystic ductular dilatation and the confirmatory diagnosis is always made postoperatively by histopathological examination. The mainstay in the treatment of a lymphoepithelial cyst remains the surgical approach, which includes complete enucleation of the cyst along with total excision of the involved salivary gland. This is a report of a lymphoepithelial cyst involving the submandibular salivary gland and its management. PMID:25210369

    Biliary cystic disease is uncommon in Asia and very rare in Europe and the Americas. Patients with biliary cysts may present as infants, children, or adults. When patients present as adults, they are more likely to have stones in the gallbladder, common duct, or intrahepatic ducts and to present with biliary colic, acute cholecystitis, cholangitis, or gallstone pancreatitis. With increasing age at presentation, the risks of intrahepatic strictures and stones, segmented hepatic atrophy/hypertrophy, secondary biliary cirrhosis, portal hypertension, and biliary malignancy all increase significantly. Factors to be considered when performing surgery on patients with biliary cystic disease include: (1) age, (2) presenting symptoms, (3) cyst type, (4) associated biliary stones, (5) prior biliary surgery, (6) intrahepatic strictures, (7) hepatic atrophy/hypertrophy, (8) biliary cirrhosis, (9) portal hypertension, and (10) associated biliary malignancy. In general, regardless of age, presenting symptoms, biliary stones, prior surgery or other secondary problems, surgery should include cholecystectomy and excision of extrahepatic cyst(s). With respect to the distal bile duct, the surgical principle should be excision of a portion of the intrapancreatic bile duct with care to not injure the pancreatic duct or a long common channel. Resection of the pancreatic head should be reserved for patients with an established malignancy. With respect to the intrahepatic ducts, surgery should be individualized depending on whether (1) both lobes are involved, (2) strictures and stones are present, (3) cirrhosis has developed, or (4) an associated malignancy is localized or metastatic. When the liver is not cirrhotic, hepatic parenchyma should be preserved even when strictures and stones are present. If cirrhosis is advanced, hepatic transplantation may be indicated, but this sequence of events is unusual. If a malignancy has developed, oncologic principles should be followed. Whenever possible, resection of a localized tumor including adjacent hepatic parenchyma and regional lymph nodes should be performed. PMID:14598135

    One of the consequences of traumatic injuries is the chance of aseptic pulp necrosis to occur which in time may became infected and give origin to periapical pathosis. Although the apical granulomas and cysts are a common condition, there appearance as an extremely large radiolucent image is a rare finding. Differential diagnosis with other radiographic-like pathologies, such as keratocystic odontogenic tumour or unicystic ameloblastoma, is mandatory. The purpose of this paper is to report a very large radicular cyst caused by a single mandibular incisor traumatized long back, in a 60-year-old male. Medical and clinical histories were obtained, radiographic and cone beam CT examinations performed and an initial incisional biopsy was done. The final decision was to perform a surgical enucleation of a lesion, 51.4 mm in length. The enucleated tissue biopsy analysis was able to render the diagnosis as an inflammatory odontogenic cyst. A 2 year follow-up showed complete bone recovery. PMID:26393219

    A 67-year-old man presented with persistent penis and scrotum pain due to S-2 and S-3 radiculopathy caused by a sacral perineural cyst. The cyst was treated with microsurgical partial cyst removal and cyst wall imbrication, together with closure of the point through which cerebrospinal fluid (CSF) flowed from the subarachnoid space into the cyst cavity. His pain resolved without recurrence of the cyst or complications. Symptomatic perineural cysts are quite rare. Surgical closure of the point through which CSF flows from the subarachnoid space into the cyst cavity is the most important intervention for symptomatic perineural cysts. If the source of CSF leakage cannot be detected, placement of a cyst-subarachnoid shunt should be considered in addition to partial cyst removal and cyst wall imbrication. PMID:22198114

    1. Cyst walls of the potato cyst-nematode (Heterodera rostochiensis Woll.) were isolated by sieving a suspension of crushed cysts. About 12mg. of dried cyst walls was obtained from 1000 cysts. 2. The cyst walls contained mainly protein (72%, calculated from nitrogen content). On acid hydrolysis about 77% of the cyst wall went into solution. Of 19 amino acids present, proline, glycine, and alanine were the most abundant, and made up about 50% by weight of the total amino acids. The amino acid composition suggested that collagen-like proteins predominated in the cyst wall and larval cuticle. 3. A small amount of glucosamine (1·5%) was present in the hydrolysates, but chitin was not detected in the cyst walls. 4. Other components of the cyst walls were lipid (2%), carbohydrate (0·5%) and a small amount of inorganic matter (ash, 5%). Polyphenols (2% by wt. of the cyst walls) occurred in the acid hydrolysates. The dark pigments of the cyst wall were not indole-containing melanins. PMID:5665885

    Proper disposal of carcasses and offal after home slaughter is difficult in poor and remote communities and therefore dogs readily have access to hydatid cysts containing offal from livestock, thus completing the parasite cycle of Echinococcus granulosus and putting communities at risk of cystic echinococcosis. Boiling livers and lungs which contain hydatid cysts could be a simple, efficient and energy- and time-saving way to kill the infectious protoscoleces. The aim of this study was to provide precise practical recommendations to livestock owners. Our results show that boiling the whole sheep liver and/or lung, with single or multiple hydatid cysts, for 30 min is necessary and sufficient to kill E. granulosus protoscoleces in hydatid cysts. Advertising on this simple rule in at-risk communities would be an efficient and cheap complement to other veterinary public health operations to control cystic echinococcosis. PMID:25456565

We report the first known case of multiple müllerian cysts in the thorax in a 35-year-old woman with cough and an abnormal chest roentgenogram. Multiple bilateral cysts were resected thoracoscopically. Histologic examination showed benign ciliated tubal epithelium that stained positive with immunohistochemical stains for estrogen receptor (ER), cancer antigen 125 (CA-125), Wilms' tumor protein 1 (WT-1), and paired box gene 8 (PAX8), confirming müllerian origin. We also review the embryogenesis and pathologic characteristics of müllerian cysts and the rare occurrence of their migration to the thorax. PMID:26522538

    A nasoalveolar cyst is a rare, non-odontogenic soft tissue cyst encountered in the anterior maxillary labial sulcus as an asymptomatic soft tissue swelling. Often, patients with these cysts report them to the dental clinic where they are mistaken for odontogenic lesions by the dental surgeon, especially if concomitant dental problems are present. They cannot be detected by routine conventional dental radiography as they are peripheral, lying within the mucosa thereby posing a diagnostic challenge.

    Introduction: Renal involvement by hydatid disease is uncommon. The patients may be asymptomatic or present with flank pain, hematuria, and hypertension. Surgery is the mainstay of treatment, and options include cyst deroofing, partial nephrectomy, and total nephrectomy. We share our experience of laparoscopic management of 3 patients with large hydatid cysts of the kidney and review the literature. Case Description: Three patients with hydatid cysts of the kidney were treated at our institution between 2008 and 2010. In all 3 patients, hydatid disease involved the left kidney. One of the three cases also had concomitant liver involvement. Abdominal pain was the predominant symptom. A flank mass was palpable in 2 patients. The diagnosis was confirmed on abdominal ultrasonography and computed tomography in all 3 patients. Laparoscopic management was successfully completed in 2 patients. A large intrahepatic cyst in 1 patient prompted conversion to an open procedure. A special hydatid trocar-cannula system helps in eliminating the possibility of spillage from the cyst while puncturing and aspirating the cyst. Discussion: There are few reports on laparoscopic management of this uncommon disease of the kidney. In our series the laparoscopic management was attempted in all 3 cases. The procedures included laparoscopic aspiration of the cyst contents along with subtotal excision of the ectocyst in 2 patients and nephrectomy in 1 patient. The latter case had to be converted to an open procedure because of inaccessibility of the intrahepatic liver hydatid cyst. Laparoscopic management of renal hydatid cysts is feasible and safe.

    A rapid high performance liquid chromatographic method was developed including an internal standard for the measurement of mature and senescent crosslinks concentration in non-demineralized bone hydrolysates. To avoid the demineralization which is a tedious step, we developed a method based on the use of a solid-phase extraction procedure to clean-up the samples. It resulted in sensitive and accurate measurements: the detection limits as low as 0.2 pmol for the pyridimium crosslinks and 0.02 pmol for the pentosidine. The inter- and intra-assay coefficients of variation were as low as 5% and 2%, respectively, for all crosslinks. PMID:19027371

    Summary Parathyroid cysts are rare (0.8–3.41% of all parathyroid lesions) and usually arise secondary to cystic degeneration of parathyroid adenomas. Intrathyroidal parathyroid cysts are extremely rare with only three cases reported till date. We present a 24-year-old female with clinical and biochemical features of primary hyperparathyroidism (PHPT; Ca2 +: 12.1?mg/dl; intact parathyroid hormone (iPTH): 1283?pg/ml) and poor radiotracer uptake with minimal residual uptake in the left thyroid lobe at 2 and 4?h on Tc99m sestamibi imaging. Neck ultrasonography (USG) revealed 0.6×1?cm parathyroid posterior left lobe of thyroid along with 22×18?mm simple thyroid cyst. USG-guided fine-needle aspiration (FNA) and needle tip iPTH estimation (FNA-iPTH) from parathyroid lesion was inconclusive (114?pg/ml), necessitating FNA of thyroid cyst, which revealed high iPTH (3480?pg/ml) from the aspirate. The patient underwent a left hemithyroidectomy. A >50% drop in serum iPTH 20?min after left hemithyroidectomy (29.4?pg/ml) along with histopathology suggestive of intrathyroidal cystic parathyroid adenoma (cystic lesion lined by chief cell variant parathyroid cells without any nuclear atypia, capsular or vascular invasion surrounded by normal thyroid follicles) confirmed that the parathyroid cyst was responsible for PHPT. This report highlights the importance of FNA-iPTH in localizing and differentiating a functional parathyroid lesion from nonfunctional tissue in PHPT. Learning points Fine-needle aspiration from suspected parathyroid lesion and needle tip iPTH (FNA-iPTH) estimation from the saline washing has an important role in localizing primary hyperparathyroidism (PHPT).FNA-iPTH estimation may help in differentiating functional from nonfunctional parathyroid lesion responsible for PHPT.iPTH estimation from aspirate of an intrathyroid cyst is helpful in differentiating intrathyroidal parathyroid cyst from thyroid cyst.

Both of them were operated and postoperatively their symptoms were disappeared immediately. We experienced the excellent treatment outcome with the surgical management of symptomatic perineural cysts in the sacral region. We assume that the theory of congenital origin including a familial tendency is the most plausible of the hypotheses that have been proposed. PMID:19096672

    Mullerian cyst of the uterus, also known as endosalpingiosis, is rare and often can be misdiagnosed as adnexal cyst on pelvic sonography. A 47-year-old woman was referred for an incidental finding of a right adnexal mass on pelvic sonography, suspected to be an ovarian cyst. During laparoscopy, a pedunculated cystic mass arising from the right anterior uterine wall was seen. The mass was resected laparoscopically and histologic examination showed a benign Mullerian cyst of the uterus. Diagnosis of Mullerian cyst of the uterus can be challenging. However, with increased awareness, preoperative diagnosis of this condition should be possible sonographically. PMID:23949900

    A 34-year-old man was admitted in our department with a 3 months history of epigastric pain, abdominal distension and tenderness. Helical computed tomography scan and magnetic resonance imaging showed a 10 cm low-density fluid-filled polilobate cystic lesion with internal septations and calcifications located between the left lobe of the liver, shorter gastric curvature, pancreas and mesocolon. Laparoscopic exploration was performed. Macroscopically the lesion was a unilocular serous cyst with a thick fibrous wall. Histopathology revealed a thin fibrous wall with a single layer of flattened to cuboidal mesothelial cell lining lacking any cellular atypia. The patient is currently alive without evidence of recurrence at 6 months. Cysts of mesothelial origin are rare lesions seen more frequently in young and middle-aged women, mostly benign and located in the mesenteries or omentum. Diagnosis is usually based on clinical examination and radiographic imaging. Immunohistochemistry is used to differentiate histologic type, with simple mesothelial cysts being positive for cytokeratins and calretinin and negative for CD31. The laparoscopic approach appears safe, feasible and less-invasive without compromising surgical principles and today should be considered the gold standard in most cases. PMID:26917928

    A 25-year-old man presented with left lumboischialgia refractory to medical treatment. Neurological examination revealed L5 and S1 radiculopathy which rapidly worsened over a short period. Magnetic resonance imaging demonstrated disk bulging with a discal cyst at the L4-5 intervertebral space and disk herniation at the L5-S1 intervertebral space. Computed tomography showed osteolytic change of the L5 vertebral body adjacent to the cyst. Resection of the cyst and removal of the herniated disk were performed following fenestration of the L4-5 and L5-S1 interlaminar spaces. Bloody serous fluid followed by clear serous fluid was recognized during the aspiration and partial resection of the cyst at the L4-5 level. Histological examination demonstrated a cyst wall consisting of fibrous connective tissue without a single-layer lining of cells, and fibrin deposits. The patient's symptoms disappeared immediately after the operation. This osteolytic lumbar discal cyst possibly occurred subsequent to hemorrhage from the epidural venous plexus following intervertebral disk injury, hematoma encapsulation by connective fibrous tissue, and cyst wall formation in reaction to the disk injury and hemorrhage. The cyst may have enlarged due to the inflow of the serous fluid from the water-containing degenerated disk. PMID:18719328

    Background: Different research groups reported a negative correlation between cancers and parasitical infections. As an example, the prevalence of a hydatid cyst among patients with cancer was significantly lower than its prevalence among normal population. Tn antigens exist both in cancer and hydatid cyst. This common antigen may be involved in the effect of parasite on cancer growth. So in this work, common antigens between hydatid cyst and cancers have been investigated. Materials and Methods: Different hydatid cyst antigens including hydatid fluid, laminated and germinal layer antigens, and excretory secretory antigens of protoscolices were run in SDS PAGE and transferred to NCP paper. In western immunoblotting, those antigens were probed with sera of patients with different cancer and also sera of non-cancer patients. Also, cross reaction among excretory secretory products of cancer cells and antisera raised against different hydatid cyst antigen was investigated. Results: In western immunoblotting, antisera raised against laminated and germinal layers of hydatid cyst reacted with excretory secretory products of cancer cells. Also, a reaction was detected between hydatid cyst antigens and sera of patients with some cancers. Conclusion: Results of this work emphasize existence of common antigens between hydatid cyst and cancers. More investigation about these common antigens is recommended. PMID:26962511

    Background and Aim The aim of this study was to elucidate the risk of subsequent biliary malignancy in patients undergoing cyst excision for congenital choledochal cysts. Methods A retrospective analysis of 94 patients who had undergone cyst excision for congenital choledochal cysts was conducted. The median age at the time of cyst excision and median follow-up time after cyst excision were 7 years and 181 months, respectively. Results Biliary tract cancer developed in four patients at 13, 15, 23, and 32 years after cyst excision. The cumulative incidences of biliary tract cancer at 15, 20, and 25 years after cyst excision were 1.6%, 3.9%, and 11.3%, respectively. The sites of biliary tract cancer were the intrahepatic (n = 2), hilar (n = 1), and intrapancreatic (n = 1) bile ducts. Of the four patients with biliary tract cancer after cyst excision, three patients underwent surgical resection and one patient received chemo-radiotherapy. The overall cumulative survival rates after treatment in the four patients with biliary tract cancer were 50% at 2 years and 25% at 3 years, with a median survival time of 15 months. Conclusions The risk of subsequent biliary malignancy in patients undergoing cyst excision for congenital choledochal cysts seems to be relatively high in the long-term. The risk of biliary malignancy in the remnant bile duct increases more than 15 years after cyst excision. Despite an aggressive treatment approach for this condition, subsequent biliary malignancy following cyst excision for congenital choledochal cysts shows an unfavorable outcome. PMID:22989043

    A 50-year-old male presented with acutely progressed paraplegia. His magnetic resonance imaging demonstrated two well-demarcated components with opposite signals in one cystic lesion between the T1- and T2-weighted images at the T1 spine level. The patient showed immediately improved neurological symptoms after surgical intervention and the histopathological exam was compatible with a neurenteric cyst. On operation, two different viscous drainages from the cyst were confirmed. A unique similarity of image findings was found from a review of the pertinent literature. The common findings of spinal neurenteric cyst include an isointense or mildly hyperintense signal relative to cerebrospinal fluid for both T1- and T2-weighted images. However, albeit rarer, the signals of some part of the cyst could change into brightly hyperintensity on T1-weighted images and hypointensity on T2-weighted images due to the differing sedimentation of the more viscous contents in the cyst.

    Although most of sacral perineural cysts are asymptomatic, some may produce symptoms. Specific radicular pain may be due to distortion, compression, or stretching of nerve root by a space occupying cyst. We report a rare case of S1 radiculopathy caused by sacral perineural cyst accompanying disc herniation. The patient underwent a microscopic discectomy at L5-S1 level. However, the patient's symptoms did not improved. The hypesthesia persisted, as did the right leg pain. Cyst-subarachnoid shunt was set to decompress nerve root and to equalize the cerebrospinal fluid pressure between the cephalad thecal sac and cyst. Immediately after surgery, the patient had no leg pain. After 6 months, the patient still remained free of leg pain. PMID:19352483

    Choledochal cysts are cystic dilation of extrahepatic duct, intrahepatic duct, or both that may result in significant morbidity and mortality, unless identified early and managed appropriately. The incidence is common in Asian population compared with western counterpart with more than two third of the cases in Asia being reported from Japan. The traditional anatomic classification system is under debate with more focus on etiopathogenesis and other aspects of choledochal cysts. Even though categorized under the same roof, choledochal cysts vary with respect to their natural course, complications, and management. In this review, with the available literature on choledochal cysts, we discuss different views about the etiopathogenesis along with the natural course, complications, diagnosis, and surgical approach for choledochal cysts, which also explains why the traditional classification is questioned by some authors.

    2003-12-01

    The mandibular buccal bifurcation cyst (MBBC) is a cystic lesion, which occurs on the buccal surface of the permanent mandibular first molar in children around 6-8 years old. Treatment of the cyst has been controversial: extraction of the involved tooth and enucleation of the cyst, or only enucleation, without extraction. The aim of this article is to familiarize oral and maxillofacial surgeons with this entity and the appropriate treatment approach. The diagnostic features of MBBC are described and the treatment approach in five patients with a total of seven cysts is presented. Two cases were identified in identical twins. Enucleation of the cyst without extraction of the involved tooth is the treatment of choice when the available data and experience in treating MBBC are considered. PMID:14636611

  20. EXCISION OF GIANT CELL TUMOR OF TENDON SHEATH WITH BONE INVOLVEMENT BY MEANS OF DOUBLE ACCESS APPROACH: CASE REPORT

    2015-01-01

    Giant cell tumors of the tendon sheath are common lesions and are the second most frequent tumors in the hand, after synovial cysts. They are diagnosed by means of clinical examination and complementary examinations (simple radiography and magnetic resonance). Erosion and invasion of the phalangeal bone affected may be seen on radiological examination. Magnetic resonance may show a “fluorescent or radiant effect” may be observed, caused by the high quantity of hemosiderin inside the tumor. Surgical treatment is the commonest practice, and complete excision is important for avoiding recurrence of the tumor, especially when bone invasion is observed on imaging examinations, which is generally related to greater tumor recurrence. In this paper, a case of a giant cell tumor of the tendon sheath in the middle phalanx of the third finger of a 45-year-old female patient is presented. This was successfully treated by means of surgery using a double access approach (dorsal and volar).

    A simple spectrophotometric method is developed here for the determination of phosphate present in the samples of soil, detergents, water, bone and food based on the formation of phosphomolybdate complex with the added molybdate followed by the reduction of the complex with thiourea in aqueous sulfuric acid medium. The system obeys Beer's law at 840 nm in the phosphate concentration range, 0.5-10.0 ?g/ml. Molar absorptivity, correlation coefficient and Sandell's sensitivity values are found to be 1.712 mol -1 cm -1, 0.9769 and 0.0555 ?g cm -2 respectively. For a comparison of the results determined from the developed method, phosphate present in the same set of samples is determined separately following an official method. The results of the developed method are agreeing well with those of the official phosphomolybdate method.

    Cutaneous ciliated cyst was described as a painless cyst occurring on the lower limbs of women between the ages of 15 and 30 years. The cysts are typically lined by ciliated cuboidal to columnar epithelium with pseudostratified areas and focal squamous metaplasia is occasionally present. Immunohistochemical studies have demonstrated that the cysts are PR and ER positive, similar to the epithelia of the fallopian tubes. However, outliers of cutaneous ciliated cysts, including those in male patients and in unexpected locations such as the scalp, finger, and scapular area, have been reported. Thus, some hypotheses have been proposed including the Mullerian heterotopias, ciliated metaplasia of eccrine sweat glands, and embryonic remnants of the cloacal membrane. We report a rare case of cutaneous ciliated cyst on the left shoulder of a 7-year-old boy and this is the eighth case of cutaneous ciliated cyst in male patients. Moreover, through reviewing the articles, we try to propose the classification of the cutaneous ciliated cysts into the cutaneous Mullerian cysts and the ciliated cutaneous eccrine cysts.

    A rare case of a leptomeningeal cyst is reported in a twin male neonate delivered using a vacuum extractor, who presented a huge, non-pulsating, oedematous mass overlying the frontal fontanelle after birth. The mass was initially diagnosed as a cephalo haematoma. Ultrasonography indicated intracranial bleeding and a subsequent CT scan revealed an intraparenchymal bleeding above the left frontal horn, combined with a thin, left-sided, subdural haematoma and subarachnoid haemorrhage in the left Sylvian fissure. Apart from a bulging soft and round formation (2 x 2 x 3 cm) next to the anterior fontanel growing since birth, the neurological development of the infant was normal. MRI examination at the age of 7 months revealed that it consisted of a cystic mass (leptomeningeal cyst) connected to the left frontal horn, stretching right through the brain and also penetrating the dura mater. No signs of the perinatal haematomas were observed at this time. Surgical treatment, with fenestration of the cyst into the frontal horn and a watertight duraplasty with a periosteal flap and thrombin glue covered by small bone chips, was performed at 9 months of age. Due to a residual skull bone defect a second cranioplasty with autologous skull bone was performed three and half years later. During a follow-up period of 12 years the neurological and psychological development of the boy has been indistinguishable to that of his twin brother, indicating the satisfactory outcome of the treatment.

    This study aimed to improve the surgical removal procedure for nasal vestibular cysts. Twenty-three patients with nasal vestibular cysts underwent surgical removal of the cyst via a transoral sublabial approach and another 30 patients via a modified intranasal endoscopic excision method. The 30 patients were treated with local anesthesia and the roof of the cyst, which was firmly attached to the mucous membrane of the anterior floor of the nasal cavity, was removed transnasally with microdebrider. Bleeding of the opening was stopped by electric coagulation without nasal packing. Among the 30 consecutive patients who underwent the modified surgical procedure, all patients were successfully treated. The mean duration of surgery was 5.7 ± 2.6 min. The mean estimated blood loss was 3.5 ± 2.1 ml. All patients were outpatients. The mean hospital stay was 1 h. The mean total cost was 140. The visual analog scale scores of postoperative pain, pressure and nasal obstruction were 1, 0 and 1, respectively. The incidence rate of postoperative lip swelling or numbness was 0 %. Postoperative endoscopic findings revealed that the cyst was replaced by an air-containing sinus with a persistent opening at the anterolateral nasal floor. There was no recurrence during a mean follow-up of 18 months. The modified intranasal endoscopic excision is a simple, less invasive, low-cost and effective surgical procedure for the treatment of nasal vestibular cysts. It might change the pattern of treatment for nasal vestibular cysts in China. PMID:24906844

  6. Strategies To Discover the Structural Components of Cyst and Oocyst Walls

    PubMed Central

    Bushkin, G. Guy; Chatterjee, Aparajita; Robbins, Phillips W.

    2013-01-01

    Cysts of Giardia lamblia and Entamoeba histolytica and oocysts of Toxoplasma gondii and Cryptosporidium parvum are the infectious and sometimes diagnostic forms of these parasites. To discover the structural components of cyst and oocyst walls, we have developed strategies based upon a few simple assumptions. Briefly, the most abundant wall proteins are identified by monoclonal antibodies or mass spectrometry. Structural components include a sugar polysaccharide (chitin for Entamoeba, β-1,3-linked glucose for Toxoplasma, and β-1,3-linked GalNAc for Giardia) and/or acid-fast lipids (Toxoplasma and Cryptosporidium). Because Entamoeba cysts and Toxoplasma oocysts are difficult to obtain, studies of walls of nonhuman pathogens (E. invadens and Eimeria, respectively) accelerate discovery. Biochemical methods to dissect fungal walls work well for cyst and oocyst walls, although the results are often unexpected. For example, echinocandins, which inhibit glucan synthases and kill fungi, arrest the development of oocyst walls and block their release into the intestinal lumen. Candida walls are coated with mannans, while Entamoeba cysts are coated in a dextran-like glucose polymer. Models for cyst and oocyst walls derive from their structural components and organization within the wall. Cyst walls are composed of chitin fibrils and lectins that bind chitin (Entamoeba) or fibrils of the β-1,3-GalNAc polymer and lectins that bind the polymer (Giardia). Oocyst walls of Toxoplasma have two distinct layers that resemble those of fungi (β-1,3-glucan in the inner layer) or mycobacteria (acid-fast lipids in the outer layer). Oocyst walls of Cryptosporidium have a rigid bilayer of acid-fast lipids and inner layer of oocyst wall proteins. PMID:24096907

    The authors report the case of a giant medial meniscal cyst in an osteoarthritic knee of an 82-year-old woman that was successfully treated with only arthroscopic cyst decompression. The patient noticed a painful mass on the medial side of the right knee that had been gradually growing for 5 years. Magnetic resonance imaging showed an encapsulated large medial cystic mass measuring 80×65×40 mm that was adjacent to the medial meniscus. An accompanying horizontal tear was also detected in the middle and posterior segments of the meniscus. The medial meniscus was resected up to the capsular attachment to create bidirectional flow between the joint and the cyst with arthroscopic surgery. Magnetic resonance imaging performed 14 months postoperatively showed that the cyst had completely disappeared, and no recurrence was observed during a 2-year follow-up period. An excellent result could be obtained by performing limited meniscectomy to create a channel leading to the meniscal cyst, even though the cyst was large. Among previously reported cases of meniscal cysts, this case is the largest to be treated arthroscopically without open excision. [Orthopedics. 2016; 39(1):e166-e168.]. PMID:26726987

    Purpose and Introduction Dentigerous cysts are epithelial in origin and are the most commonly found cyst in children. The majority of these lesions are usually a radiological finding and are capable of quite large before being diagnosed. The standard treatment for these cysts is the enucleation and the extraction of the affected tooth. However, if the patient is a child and the affected tooth is not developed, a more conservative attitude should be considered. Material and Methods (Clinical case): A 7-year-old patient is presented with an eruptive backlog of the lower permanent first molars. Radiological examination reveals two radiolucid lesions in relation to them, which are compatible with a dentigerous cyst, and in relation to the inferior aveolar nerve and various germs. A partial enucleation is carried out, maintaining all the dental germs related to the cyst in mouth and monitoring the patient until the case study is over. Results and Discussion Diagnosis and early treatment of these lesions in children is of great importance, especially in cases where the lesions enclose permanent teeth. Conclusions Whenever possible, a conservative attitude should be taken, one that allows for the maintenance of the dentition and treatment of the associated cyst in order to not compromise either the occlusion or the mental state of these patients. Key words:Dentigerous cyst, conservative treatment, dental impaction, child. PMID:26644847

  9. Choledochal cyst associated with portal hypertension.

    2003-12-01

    Portal hypertension is a known complication of delayed presentation of choledochal cyst. In the literature, choledochal cyst presenting with portal hypertension has not been addressed adequately. The aetiology of portal hypertension in these cases has not been well studied, but it may be related to compression of the cyst over the portal vein, secondary biliary cirrhosis, or even extrahepatic portal venous thrombosis. We present our experience with four cases of choledochal cysts with associated portal hypertension over a 10-year period (1991-2001). Gastrointestinal bleeding, splenomegaly or incidental discovery of oesophageal varices led to the diagnosis of associated portal hypertension. Excision of choledochal cyst and bilioenteric bypass may not be feasible in those patients with massive collaterals in the region of porta with secondary portal hypertension. An initial approach of internal drainage (endoscopic/operative) of the cyst may allow regression of collaterals and subsequent safe excision of the cyst in this difficult group of patients. The liver function and histopathology dictated the final outcome. PMID:14704806

    The authors have studied the evolution of chronic synovitis and of cysts in hemophilic patients, through measurement of the articular circumference or of the cyst. To obtain this, they have used a folding rule and liquid cristal strips, that have the characteristic, that they change colours from braunish to orange, from greenish to bluish according to the thermic gradient revealed. The authors have studied 21 hemophilic patients, affected from chronic synovitis for a total of 23 articulations and 5 patients with cyst. All patients have undergone several controls reporting dates revealed at 2,6 and 12 months from beginning of disease. The authors conclude, underlining the usefulness of this simple methodic that permits: - a reliable valutation of the therapeutic (profilatic) scheme applied to every single patient and gives a prognostic precision; - distinguishing, in fact, the recovery from the clinical recovery of the synovitis in order to avoid the appearance of unpleasant relapses.

    A 9-month-old p53-null female mouse was found dead in its cage. At necropsy, a large thymic mass encompassed the heart. Microscopically, the mass was composed of numerous varying-sized cysts lined with simple squamous epithelial cells to columnar ciliated cells. Also present within this mass was a large aggregate of loosely arranged fusiform-shaped cells. These cells also were found in smaller numbers in the connective tissue surrounding the cysts. The larger aggregate of fusiform cells was positive for desmin and S-100 and negative for smooth muscle actin. Electron microscopy revealed well-formed Z lines and I bands of skeletal muscle phenotype. A diagnosis of rhabdomyoma within a congenital multilocular thymic cyst was made. The thymus contains a small population of myoid cells, which should be taken in consideration when evaluating thymic tumors. PMID:20080493

    Juxtafacet cysts are implicated in neural compression. Thus far, it is known that surgical removal is the definitive treatment for symptomatic juxtafacet cyst because spontaneous regression is rare, and the failure rate of conservative treatment is high. We have reported a rare case of right-sided juxtafacet cyst development after the spontaneous resolution of contralateral left-sided facet cyst. The left-sided facet cyst resolved spontaneously without surgical treatment, but a juxtacyst developed on the contralateral facet on the right side, as illustrated on 4-year follow-up magnetic resonance images. To the best of our knowledge, this is the first report of newly developed contralateral juxtafacet cyst after spontaneous regression. Herein, we have discussed the natural history and the management of this rare case. PMID:26819695

    The surgical ciliated cyst, also known as the "postoperative maxillary cyst" or "implantation cyst," occurs as a result of iatrogenic implantation of respiratory epithelium into a noncontiguous surgical site after sinus surgery. It typically presents as a well-defined radiolucency in the maxilla in young adults. Histopathologically, the cyst is lined by ciliated columnar, cuboidal, or pseudostratified squamous epithelium with mucous cells. We report two rare cases of a surgical ciliated cyst located in the mandible. PMID:25109584

    Trichilemmal cyst or pilar cyst is defined as a cyst containing keratin and its breakdown products. It is usually situated on the scalp with a wall resembling external hair root sheath. In this case report we present a 55-year-old man with multiple giant pilar cysts that were distributed over the whole body since childhood. One of the cyst on the chest was transformed to squamous cell carcinoma (SCC).

    Arachnoid cysts are cerebrospinal fluid collections in the spine that can present with neurological symptoms or be discovered accidentally. Intradural location of such cysts especially in the lumbosacral region is relatively rare. The association of such cysts with other congenital anomalies such as tethered cord lends evidence to the developmental origin of arachnoid cysts. We report a case of lumbosacral arachnoid cyst with tethered cord in a 6-year-old male child and discuss the etiopathogenesis and management options. PMID:24082689

    Follicular cysts are non-neoplastic skin lesions lined by follicular epithelium. The pathogenesis of these lesions is unclear. Multiple follicular cysts occur sporadically in dogs, horses and humans and are common in sheep. Here we report multiple follicular cysts in four aged alpacas (Vicugna pacos). Based on their histological features, they are most consistent with hybrid cysts. This is the first report of multiple follicular cysts in alpacas. PMID:21129052

    The thymic cysts are benign tumours of the thymo-pharyngeal canal, usually located in the cervico-mediastinal region. The authors report the case of a large thymic cyst with an ectopic right paracardiac location compressing the right heart chambers. It was a chance finding on chest X-ray of an asymptomatic 21 year old man. Though suggestive of a pericardial cyst in view of its position, curative surgical ablation allowed confirmation of the diagnosis at anatomo-pathological examination. PMID:10975041

    Supratentorial neurenteric cyst is a rare congenital lesion. We report here a case of a 33-year-old female who presented with seizures. A multicystic lesion in the left premotor cortex with moderate contrast enhancement was demonstrated with MRI. Microscopically, the lesion showed small cystic structures filled with a proteinaceous fluid. The wall of the cysts was lined with a single layer of ciliated columnar or cuboidal epithelium on a basement membrane. Glandular structures resembling gastrointestinal glands were also present. The cells of the cyst lining and glandular structures revealed strongly positive immunoreactions for epithelial markers (cytokeratin and epithelial membrane antigen). PMID:24981188

    Odontogenic cysts represent a common form of pathology of the jaws, and the natural history, clinicopathologic findings, and appropriate management strategies are important to the oral and maxillofacial surgeon. Odontogenic cysts in the pediatric populations are important pathologic entities given their potential impact on the growth and development of the maxillofacial complex. Inappropriate management strategies can severely affect the form and function of the growing child. Categorizing pediatric odontogenic cysts into inflammatory or developmental causes provides a convenient way of conceptualizing these various entities and helps facilitate the appropriate diagnosis and the subsequent management.

    A 27 year old woman who presented with upper abdominal pain was found on ultrasonography to have multiple liver cysts consistent with hydatid disease. Three years previously she had undergone evacuation of multiple infected liver cysts thought to be due to hydatid disease. Computed tomographic scanning supported the diagnosis of hydatid disease affecting the right lobe of the liver. At laparotomy the right lobe contained multiple cysts which were removed by right lobectomy. Histology revealed congenital dilatation of the intrahepatic bile ducts with fibrosis (Caroli's disease) but no evidence of hydatid disease. Images Figure 1 Figure 2 PMID:2057431

    Cysts represent a phase in the life cycle of biphasic parasitic protozoa that allow them to survive under adverse environmental conditions. Two events are required for the morphological differentiation from trophozoite to cyst and from cyst to trophozoite: the encystation and excystation processes. In this paper, we present a review of the ultrastructure of the encystation and excystation processes in Entamoeba invadens, Acanthamoeba castellanii, and Giardia lamblia. The comparative electron microscopical observations of these events here reported provide a morphological background to better understand recent advances in the biochemistry and molecular biology of the differentiation phenomena in these microorganisms.

The dramatic increasing of the cyst was followed by cranial ultrasonography for ten months. The progression of clinical symptoms couldn't be explained because after drainage of the cyst, no improvement took place. MRT with Spectroscopy lead to the tentative diagnosis, Morbus Alexander. This couldn't be proved because no biopsy of the brain was performed against the decision of the child's mother, nor postmortal (the child died at 20 months). PMID:7623429

    2002-03-01

    Odontogenic cysts that can be problematic because of recurrence and/or aggressive growth include odontogenic keratocyst (OKC), calcifying odontogenic cyst, and the recently described glandular odontogenic cyst. The OKC has significant growth capacity and recurrence potential and is occasionally indicative of the nevoid basal cell carcinoma syndrome. There is also an orthokeratinized variant, the orthokeratinized odontogenic cyst, which is less aggressive and is not syndrome associated. Ghost cell keratinization, which typifies the calcifying odontogenic cyst, can be seen in solid lesions that have now been designated odontogenic ghost cell tumor. The glandular odontogenic cyst contains mucous cells and ductlike structures that may mimic central mucoepidermoid carcinoma. Several odontogenic tumors may provide diagnostic challenges, particularly the cystic ameloblastoma. Identification of this frequently underdiagnosed cystic tumor often comes after one or more recurrences and a destructive course. Other difficult lesions include malignant ameloblastomas, calcifying epithelial odontogenic tumor, squamous odontogenic tumor, and clear-cell odontogenic tumor. Histologic identification of myxofibrous lesions of the jaws (odontogenic myxoma, odontogenic fibroma, desmoplastic fibroma) is necessary to avoid the diagnostic pitfall of overdiagnosis of similar-appearing follicular sacs and dental pulps. Fibroosseous lesions of the jaws show considerable microscopic overlap and include fibrous dysplasia, ossifying fibroma, periapical cementoosseous dysplasia, and low-grade chronic osteomyelitis. The term fibrous dysplasia is probably overused in general practice and should be reserved for the rare lesion that presents as a large, expansile, diffuse opacity of children and young adults. The need to use clinicopathologic correlation in assessing these lesions is of particular importance. Central giant cell granuloma is a relatively common jaw lesion of young adults that has an unpredictable behavior. Microscopic diagnosis is relatively straightforward; however, this lesion continues to be somewhat controversial because of its disputed classification (reactive versus neoplastic) and because of its management (surgical versus. medical). Its relationship to giant cell tumor of long bone remains undetermined. PMID:11904346

    Pulmonary multi-vesicular hydatid disease (HD) with Echinococcus granulosus is rare. A 28-year-old woman presented to our center with cough and respiratory distress. Chest x-ray and computerized tomography scan revealed bilateral giant cysts with water-lily sign (ruptured hydatid cysts). The left cyst was in vicinity of heart. With thoracotomy cysts of both lungs were removed. Thousands of translucent, homogenized small daughter cysts were discovered from the left side cyst. Pathologic examinations revealed the ruptured hydatid cysts of both lungs with daughter cysts on the left lung cyst. To best of our knowledge probably this is the first report of multi-vesicular HD in lung. We suppose that the heart pulsation was effective in the formation of daughter cysts. PMID:26180389

    1984-12-01

    A series of development stages (I-XI) have been devised to describe the development of the cyst wall of the metacestode of Hymenolepis diminuta. The cyst wall possesses tegumentary, muscular, fibrous and inner cyst tissues, the developmental rates and differentiation patterns of which are not identical. The tegumentary tissue differentiates posteriorly. Its microvillus-bearing distal cytoplasm remains simple until scolex retraction, after which rapid increase in depth followed by vacuolation occurs and basal membrane infoldings surround Phase 3 fibrogenesis fibrils. Senescence, which also affects the tegumentary cytons, then ensues. The muscle system development is posteriad and maturation, completed before scolex retraction, is followed by myocyton senescence. Posteriorly differentiated fibroblasts commence Phase 1 fibrogenesis after scolex retraction and the primary fibrous zone is fully established within approximately 6 days. Phase 2 and 3 fibrogenesis develop centrifugally, the fibrils of Phase 2 surrounding the tegumentary cytons and myocytons prior to their senescence, and those of Phase 3 lying more peripherally. The inner cyst tissue, established posteriorly, differentiates anteriorly, centripetally and early, the penultimate stage commencing just before scolex retraction, about 6 days after which the final maturation junctional complexes start development. Neither in vitro excystment nor infectivity of the definitive host can be satisfactorily achieved before the initial development of the primary fibrous zone. This may play a skeletal role during excystment, and is shown to be unaffected by the digestive enzymes which cause loss of cytoplasmic integrity in the outer regions of the cyst. PMID:6514381

    INTRODUCTION Triple assessment of a suspicious breast lesion may not always provide a definite diagnosis. We report a case of epidermoid cyst of breast, which caused diagnostic dilemma in spite of a thorough triple assessment and entailed mastectomy. PRESENTATION OF CASE A 69-year-old woman presented with a large painful retroareolar left breast mass. Clinical examination, ultrasound and mammography were highly suspicious of malignancy. However, core biopsy suggested a benign lesion. Due to size of the lesion and diagnostic uncertainty, various options were discussed with the patient. She opted for a simple mastectomy. The histology confirmed a large epidermoid cyst. DISCUSSION It is rare for an epidermoid cyst to present as such an advanced lesion, mimicking carcinoma. Excision of such a large retroareolar ‘benign’ lesion, however, may sometime entail mastectomy. This is the first reported case of an epidermoid cyst of breast necessitating mastectomy. CONCLUSION Diagnostic dilemma while dealing with a suspected breast cancer is not rare. Involvement of multidisciplinary team as well as patient is important in the decision-making. The report illustrates a rare presentation of a deep seated large epidermoid cyst of breast, which mimicked carcinoma, caused diagnostic confusion and entailed mastectomy. We strongly advocate the option of breast reconstruction in such cases. PMID:22705938

On computed tomography scan, a cystic lesion noted which is isodense in the middle cranial fossa with erosion of the underlying bone. On magnetic resonance imaging lesion was iso to hyperintense on T1-Weighted and hyperintense on T2-Weighted, brilliantly enhancing on contrast administration. Provisional diagnosis was trigeminal schwannoma, left temporal craniotomy and total excision of the cyst done. Histopathological examination showed cyst wall lined with collagen.

    Echinococcosis is a parasitic infection also called as hydatid disease or hydatidosis. Hydatidosis is a cyclo-zoonotic infection of the larvae form of Echinococcus granulosus (canine tapeworm). The majority of hydatid cysts are seen in the liver (65%) as most of the embryos are trapped within it. Infratemporal region is an unusual site for hydatidosis and has been sparsely reported in the literature. To the best of our knowledge, this is the fourth and perhaps the largest case report of hydatidosis involving the mandible in the literature in right infratemporal region involving the ramus condyle unit in a 35-year-old female with chief complaint of pain on right side of temporomandibular joint area on mastication, and opening and closing of mouth.

    Benign tumours of the bone are not cancerous and would not metastasise to other regions of the body. However, they can occur in any part of the skeleton, and can still be dangerous as they may grow and compress healthy bone tissue. There are several types of benign tumours that can be classified by the type of matrix that the tumour cells produce; such as bone, cartilage, fibrous tissue, fat or blood vessel. Overall, 8 different types can be distinguished: osteochondroma, osteoma, osteoid osteoma, osteoblastoma, giant cell tumour, aneurysmal bone cyst, fibrous dysplasia and enchondroma. The incidence of benign bone tumours varies depending on the type. However, they most commonly arise in people less than 30 years old, often triggered by the hormones that stimulate normal growth. The most common type is osteochondroma. This review discusses the different types of common benign tumours of the bone based on information accumulated from published literature. PMID:26579486

    Stafne bone defects are asymptomatic lingual bone depressions of the lower jaw. In 1942, Stafne described for the first time 35 asymptomatic, radiolucent cavities, unilaterally located in the posterior region of the mandible, between the mandibular angle and the third molar, below the inferior dental canal and slightly above the basis mandibulae. In this study, the clinical and radiological characteristics of 2 cases of Stafne bone defects were described. Orthopantomograph and CBCT were used for diagnosing the defects. The bone defects of two patients in this study were asymptomatic and any other bone lesions, such as cysts and tumors, were excluded because no signs of inflammatory or tumoral changes were evident Therefore, surgery was not considered and the patients were followed for 1 year. Stafne bone defect was an incidental finding, presenting no evolutionary changes, and as such conservatory therapy based on periodic controls was indicated. Currently, complementary techniques such as CT are sufficient to establish a certain diagnosis. PMID:23050171

    Hydatid disease, caused by the cystic stage of Echinococcus granulosus, most commonly involves the liver (59-75%) and lung (27%), and rarely involves the kidney (3%), bone (1-4%) and brain (1-2%). Even rarer sites include the heart and spleen, and skeletal muscle, with virtually no site being immune. The pancreas is an exceedingly rare site for primary disease (without concomitant involvement of the liver or peritoneum), with less than 20 reported cases in the literature. This case report describes a 48-year-old woman presenting with a solitary cystic lesion arising from the neck of the pancreas, which was ultimately determined to be a hydatid cyst on histopathological examination. It also discusses the difficulties in preoperative and postoperative management and includes a review of the literature. PMID:26336187

    The nasolabial cyst or Klestadt cyst is a relatively uncommon nonodontogenic cyst that develops in the nasal alar region; it has uncertain pathogenesis. This lesion has slow growth and variable dimensions and is characterized clinically by a floating tumefaction in the nasolabial fold area around the bridge of the nose, causing an elevation of the upper lip and relative facial asymmetry. Diagnosis is primarily made clinically; if necessary, this is complemented by imaging. This paper reports the case of a 39-year-old male patient who complained of pain in the right upper premolar region and poor aesthetics due to a firm tumor in the right wing of the nose. Initially, this was thought to be due to an odontogenic abscess; however, the differential diagnosis was that a nasolabial cyst was communicating with the apex of teeth 14 and 15. Surgical treatment was carried out, followed by histopathological examination and concomitant endodontic treatment of the teeth involved. PMID:26904312

    In all animals, germline cells differentiate in intimate contact with somatic cells and interactions between germline and soma are particularly important for germline development and function. In the male gonad of Drosophila melanogaster, the developing germline cells are enclosed by somatic cyst cells. The cyst cells are derived from cyst stem cells (CySCs) of somatic origin and codifferentiate with the germline cells. The fast generation cycle and the genetic tractability of Drosophila has made the Drosophila testis an excellent model for studying both the roles of somatic cells in guiding germline development and the interdependence of two separate stem cell lineages. This review focuses on our current understanding of CySC specification, CySC self-renewing divisions, cyst cell differentiation, and soma-germline interactions. Many of the mechanisms guiding these processes in Drosophila testes are similarly essential for the development and function of tissues in other organisms, most importantly for gametogenesis in mammals.

    Adrenal cysts represent a rare condition (approximately 250 cases have been reported). We report two additional cases: the first involved a huge lesion removed surgically and thoroughly studied preoperatively; the second was an incidental autopsy finding. Detailed ultrastructural studies have been made of both cases. We think that the basic cell of origin of the cyst is an endothelial cell lining lymphatic channels. We speculate that the pseudocysts, which have been described as having a fibrous lining, probably were at one time also lymphendothelial but, perhaps due to trauma or repeated bleeding, the major portion of the endothelial lining became replaced by collagen. The primary and secondary cystic malignancies and cases of cysts due to parasites should be classified separately from the adrenal cysts of lymphendothelial origin which probably represent a benign tumor-like overgrowth.

    Cardiac hydatidosis is rare presentation of body hydatidosis. Incidence of cardiac involvements range from 5% to 5% of patients with hydatid disease. Most common site of hydatid cyst in heart is interventricular septum and left ventricular free wall. Right ventricular free wall involvement by cyst that ruptured to pericardial cavity is very rare presentation of hydatid cyst. Cardiac involvement may have serious consequences such as rupture to blood steam or pericardial cavity. Both the disease and its surgical treatment carry a high complication rate, including rupture leading to cardiac tamponade, anaphylaxis and also death.

    A rare case is presented of a synovial cyst located at the level of C3-C4 that caused cervical myelopathy and that was preoperatively diagnosed by facet arthrography. A woman in her late seventies experienced muscle weakness and numbness in her right upper extremity and gait disturbance. MRI revealed an extradural lesion located dorsolaterally on the right side of the spinal cord at the level of C3-C4. CT facet arthrography revealed continuity of the extradural lesion with the right C3-C4 facet joint and infiltration of contrast medium into the lesion. Postoperatively, histological examination of the cyst showed fibrous tissue with calcium deposits and the presence of synovial lining. Preoperatively, cervical synovial cysts are often difficult to distinguish from other extradural lesions. In this case, facet arthrography allowed the preoperative determination of communication between the extradural lesion and the facet joint, leading to the diagnosis of a synovial cyst. PMID:21990488

    Bursae around the knee reduce friction between moving structures. When involution of suprapatellar septum fails to occur ("complete septum"), then suprapatellar bursa may stay completely separated from the knee joint cavity to form a cystic cavity. In the case of the increased volume, suprapatellar bursitis can cause painful suprapatellar swelling. The aim is to point to the possibility of arthroscopic decompression of suprapatellar cyst. In the case presented, the indication for knee arthroscopy was based on clinical examination, ultrasonography and magnetic resonance studies. The preoperative diagnosis was verified intra-operatively, and intra-articular cyst decompression was performed by arthroscopy. At the final examination 8 months postoperatively, the patient still had no pain, swelling and had full range of motion. This minimally invasive operative procedure resulted in a satisfactory anatomic and functional outcome. In this case report, we present a patient with suprapatellar cyst submitted to arthroscopic cyst decompression. PMID:22258651

    Bronchogenic cysts are rare congenital anomalies result of abnormal development of the tracheobronchial tree. They develop in the lung parenchyma or in the mediastinum. For a period of 17 years (1975-1991) a total of 46 children with bronchogenic cysts have been treated; in 6 the cysts were localized in the mediastinum. Two patients were one-year-old, 3 were in the age group 1 to 3 years and 1 was older than 3 years. Four patients were boys and 2 girls. Two children had hacking cough and attacks of dyspnea; one had swallowing difficulties. In 3 children the disease produced no symptoms and was detected on examination for pneumonia (1 child) and acute upper respiratory tract infection (2 children). All children had conventional X-ray; 5 had esophagography as well, 4--computer axial tomography, 3--echography. All children were operated (total extirpation of the cyst) and left the hospital cured.

    A conjunctival cyst is a thin-walled sac or vesicle that contains fluid. This vesicle may develop either on or under the conjunctiva. It develops due to variety of causes such as infection, inflammation, retention cyst and rarely drug induced. The authors aimed to report a case of conjuctival cyst in a 34-year-old male following instillation of anti-allergic topical drugs for over period of one year. Conjuctival cyst developing due to chronic use of anti-allergic topical drugs containing preservatives is one of the complications associated with it. Presence of a preservative in an ocular medication has often been considered in damaging the epithelium. Inclusion of a preservative is equally necessary, especially in multiple-drug therapy in order to protect against dangerous organisms accidentally gaining access during instillation.

Clinical examination and investigations confirmed an idiopathic benign retroperitoneal cyst. He underwent surgery and was discharged after making good recovery. Conclusion Retroperitoneal cysts are very rare, and most of the time they are discovered incidentally. Patients may be asymptomatic or present with abdominal pain, referred pain to the legs or weight loss. Imaging may help diagnose these lesions, but surgery is the keystone in confirming the diagnosis. This case is very rare and very educational as it highlights an unusual presentation of a benign retroperitoneal cyst. In our patient, the course of the disease was unique as the patient presented with jaundice. PMID:18261209

    Perineural cysts are believed to be asymptomatic; however, they rarely cause symptoms related to nerve root compression. Cervical symptomatic perineural cysts are in fact exceedingly rare. There are no reported cervical perineural cysts in the literature that present like cubital tunnel syndrome. A patient with motor weakness of the abductor and adductor muscles of the fingers of the left hand and hypoesthesia in the hypothenar region of the left hand presented at our clinic. A neurological examination, and neuroradiological and electrophysiological evaluations supported the finding that the patient's clinical condition was caused by a perineural cyst located around the C8 neural root. The neurological symptoms of the patient markedly improved after medical treatment. We reported the first cervical perineural cyst as presenting like cubital tunnel syndrome patient in the literature. The visualization of perineural cyst may need extra magnetic resonance imaging (MRI) sections in order to view the nerve root through the neural foramen or extraforaminal area. These lesions are benign, and the appropriate treatment is curative. PMID:21574015

    Hydatid cysts are not endemic in Malaysia and are rarely seen. We hereby report a case of hydatid cyst of the liver in a 55-year-old Chinese-Australian lady who presented with a calcified liver cyst and negative hydatid serology. A liver segmentectomy was performed and revealed a well-circumscribed, calcified liver cyst containing only creamy whitish material without the typical daughter cyst. A histological examination revealed different layers of the cyst wall and the presence of loose, calcified scolices without a daughter cyst. The case highlights the importance of considering hydatid cyst in the differential diagnosis of liver cyst even in non-endemic areas, as the ease of travelling and migration allows the condition to be seen outside the endemic region.

    Background The aim of this study was to assess the results of using the Ilizarov apparatus to transport bones in the treatment of benign bone tumors. Methods Seven patients (six males and one female) with benign bone tumors were treated by bone transport with an Ilizarov apparatus at our institution. Their mean age at surgery was 14.4 years (range, 4.8 to 36.9 years). The histological diagnoses were osteofibrous dysplasia (4), giant-cell tumor (1), intraosseous cavernous hemangioma (1), and aneurysmal bone cyst (1). Three radiological indices were used for evaluating the results: an external fixation index, a distraction index, and a maturation index. The bone and functional results were evaluated according to the Association for the Study and Application of the Method of Ilizarov classification. Results Five patients had bone union at the reconstructed site, one patient had a local recurrence, and the other had a nonunion at the docking site. The mean length of distraction was 7.3 cm (range, 5.1 to 12.1 cm). The mean external fixation index was 26.0 day/cm (range, 19.8 to 32.5 day/cm), the distraction index was 9.6 day/cm (range, 6.8 to 12.0 day/cm), and the maturation index was 14.9 day/cm (range, 8.0 to 22.5 day/cm). Ultimately, the bone and the functional results were rated excellent in six cases and good in one case. Conclusions Bone transport using the Ilizarov apparatus is a good treatment option in patients with bone defects after the resection of an active or aggressive benign bone tumor. PMID:26217473

    Chrysophytes, also known as the golden-brown algae (classes Chrysophyceae and Synurophyceae), often form an essential component of phytoplankton in oligotrophic northern waters. All chrysophytes are believed to produce siliceous resting stages which are often well preserved and abundant in the sediments of most lakes. These resting stages also known as stomatocysts or simply cysts have recently been used in a variety of palaeoenvironmental studies linking cyst assemblages to certain environmental variables such as temperature, pH, salinity and ice cover times. For most of the cysts the cyst producing chrysophyte species is still unknown. Cyst identification is based on the size, shape, ornamentation and the pore morphology of the cyst. The problem however is the minuscule surface structure of the cyst which can often be detected only using a Scanning Electron Microscope (SEM). The use of a SEM is usually expensive and time-consuming but leaves an image of each cyst counted for future reference. The problem with using a SEM is the fact that, unlike with a light microscope, you cannot see through the cyst if the pore is not visible and therefore you are left with a large number of cysts which in some cases have several different identity options. The use of a light microscope is faster but cysts often have to be put into collective categories which can lead into problems in palaeoreconstructions if cysts in the same group have different environmental preferences. More problems in identification arise when cysts are corroded in the sediment or not fully developed. Since no larger scale chrysophyte cyst studies have previously been carried out in Finland (or Fennoscandia), the sediment material also contains many previously undescribed cyst morphotypes. Here we discuss the challenges of cyst identification and the use of chrysophyte cysts in paleoclimatic reconstructions based on circa 15000 SEM images of cysts in Finnish lakes.

    Although Sistrunk operation is the standard method to treat thyroglossal duct cyst, the reported recurrence rates after a "classic" or "modified" Sistrunk procedure still varied from 0 to 15.8 %, indicating the existence of some technical uncertainties. While simple cystectomy has been recognized as the most important prognostic factor predicting thyroglossal duct cyst recurrence, whether other clinico-pathological parameters also affect disease recurrence has not been well studied. We retrospectively reviewed the medical records of all patients who underwent thyroglossal duct cyst surgery between June 1998 and June 2014 at our institution. Among the 180 primary patients, 160 patients received a "conservative" Sistrunk operation, while the remaining 20 patients received simple cystectomy only. Five patients (2.8 %, 5/180) had recurrence. Four of them received simple cystectomy while 1 had "conservative" Sistrunk operation. In univariable analysis, age (p = 0.02), history of previous infection (p = 0.004) and the type of resection (p = 0.001) were significantly correlated with disease recurrence. In multivariable analysis, the type of resection turned out to be the most important factor (p = 0.03) related to recurrence. In the most parsimonious model selected by backward elimination, both history of infection (p = 0.048) and the type of resection (p = 0.02) were important predictors of postoperative recurrence. Our results demonstrated that a "conservative" Sistrunk approach could provide a comparably low recurrence rate (0.6 %, 1/160) in dealing with primary thyroglossal dust cysts. Routine dissection of suprahyoid tissue may not be imperative. Overall, the type of resection and history of infection are the most important predictors of recurrence for thyroglossal duct cyst.

    A 10-year-old, neutered male Labrador retriever presented with progressive left hind lameness. Ultrasonography revealed large, subcutaneous, ovoid cysts around the stifle joint. Radiographic and computed tomographic images revealed periosteal reaction of the distal femur. Magnetic resonance (MR) imaging showed a large cyst that was hypointense in T1-weighted images, hyperintense in T2-weighted images and had a thin lining that was enhanced by intravenous gadonium injection. The cyst communicated with the joint cavity and other small cysts around the joint. Histopathology of an excisional biopsy specimen led to diagnosis of ganglion cyst. This report provides MR images of a ganglion cyst in a canine stifle. PMID:24257194

    Synovial cysts at the atlantoaxial level are found uncommonly. Lumbar symptomatic cases are treated by percutaneous cyst aspiration with or without corticoid injection or by surgical resection, but synovial cysts at the C1-C2 level are usually treated by surgery. We report here a 92-year-old woman with a retro-odontoid synovial cyst producing spinal cord compression that was treated by percutaneous aspiration of the cyst under CT guidance. To our knowledge, this is the first reported case of an atlantoaxial synovial cyst successfully treated with a minimally invasive procedure.

    The management of certain ovarian cysts has evolved from the traditional and often quite radical surgical approach to a more conservative approach. Much of this change can be attributed to the improvement in laparoscopic surgical technique. After a brief discussion of the differential diagnosis and clinical presentation of ovarian cysts, ultrasonographic features of certain ovarian cysts will be reviewed. Certainly the ability to characterize cysts ultrasonographically has facilitated gynecologists' ability to predict the neoplastic potential of a cyst and therefore to justify the more conservative approach. The various techniques of laparoscopic ovarian cyst aspiration, fenestration, and cystectomy will then be described. PMID:1839754

    The benefits and risks of surgery for splenic hydatid cyst (SHC) remain controversial. We aimed to share our experience about a surgical approach for SHC. Sixteen consecutive patients with SHC disease who underwent open splenectomy at our hospital between January 2006 and July 2012 were retrospectively evaluated. Data on the patients' demographic features, clinical findings, radiological and serological diagnostic methods, and surgical and medicinal treatment options were collected and used to generate descriptive profiles of diagnosis, treatment course, and outcome. The patient population was composed of 6 females and 10 males, with an age range of 18 to 79 years (mean age: 47.0 ± 18.0). Radiological examinations detected hydatid cysts in spleen alone (n = 7) or both spleen and liver (n = 9). Preoperative serological testing identified 13 of the patients as IHA positive. All except 1 patient received a 10- to 21-day preoperative course of albendazole therapy and all patients received vaccination 1 week prior to surgery. Seven patients underwent splenectomy. The remaining patients underwent splenectomy with partial cystectomy and omentopexy (n = 6), partial cystectomy and unroofing (n = 1), pericystectomy (n = 1), or pericystectomy with partial nephrectomy (n = 1). All except one patient received a 10- to 45-day postoperative course of albendazole. No patients developed serious complications or signs of recurrence during the follow-up. The clinical profile of SHC disease at our hospital includes diagnosis by radiological methods, splenectomy treatment by simple or concomitant procedures according to the patient's symptoms, cyst size, number and localization, and compression of adjacent organs, and adjunct vaccination to decrease risk of postoperative septic complications. This profile is associated with low risk of complications and high therapeutic efficacy. PMID:24229022

    The purpose of this paper is to point out the value of CBCT exam in pre and postoperative diagnosis assessment of inflammatory radicular cysts together with full appreciation of local integration of alloplastic graft materials used to repair the osseous defects. There were statistically retrospective evaluated the pre and postoperative results of CBCT and x-ray examinations of 34 patients with inflammatory radicular cysts clinically, biologically and histopathologically assessed at Oral and Maxilo-Facial Surgery Clinic from Timisoara. In all cases we proceeded to surgical radicular cysts removement, extraction of the associated non-vital tooth together with alloplastic graft materials repairement of the osseous defects. The CBCT preoperative scans clearly showed the extent, the morphological characteristics and the topoanatomic reports, in all 34 cases of inflammatory radicular cysts together with regional endodontic status. The CBCT postoperative scans revealed the very local integration of alloplastic graft materials used to repair the osseous defects and, in some cases, the dental rehabilitation by metallic implants. CBCT scan is the imaging method of choice in pre and postoperative diagnosis assessment of inflammatory radicular cysts together with alloplastic graft materials repairement of the osseous defects and dental rehabilitation by metallic implants, due to high specific abilities in bone tissue 3D evaluation.

    Objective To determine whether intra- and periarticular cyst-like lesions of the knee are associated with incident knee pain and incident radiographic knee osteoarthritis (OA). Design The Multicenter Osteoarthritis (MOST) Study is a cohort of individuals who have or are at high risk for knee OA. Using a nested case-control study design, we investigated the associations of cyst-like lesions (Baker’s, meniscal and proximal tibiofibular joint (PTFJ) cysts, and prepatellar and anserine bursitides) with (a) incident pain at 15- or 30-month follow-up and (b) incident radiographic OA at 30-month follow-up. Baseline cyst-like lesions were scored semiquantitatively using the Whole Organ Magnetic Resonance Imaging Score (WORMS). Conditional logistic regression models were used to assess the relation between these lesions and the outcomes, adjusting for potential confounding factors (i.e. cartilage loss, meniscal damage, bone marrow lesions, synovitis and joint effusion, which were also scored using WORMS). Results Incident knee pain study included 157 cases and 336 controls. Prevalence of meniscal and PTFJ cysts in the case group was twice that in the control group (9 (6%) vs. 9 (3%) and 9 (6%) vs. 10 (3%), respectively). Incident radiographic OA study included 149 cases and 298 controls. Prevalence of grade 2 Baker’s cysts and PTFJ cysts in the case group was approximately 4 times that in the control group (16 [11%] vs. 9 [3%] and 6 [4%] vs. 3 [1%], respectively). However, none of the cyst-like lesions was associated with incident pain or radiographic OA after fully adjusted logistic regression analyses and correction of p-values for multiple comparisons. Conclusion None of the analyzed lesions was an independent predictor of incident knee pain or radiographic OA. Intra- and periarticular cyst-like lesions are likely to be a secondary phenomenon seen in painful or OA-affected knees, rather than a primary trigger for incident knee pain or radiographic OA.

    Neurenteric cysts are CNS lesions most frequently occurring in the spinal cord. Intracranial neurenteric cysts are rarer, typically presenting with headache, mass effect, or location-specific symptoms. The area postrema is known as the emetic center of the brain; lesions can cause nausea and vomiting. Our case, featuring a neurenteric cyst of the area postrema, illustrates the importance of considering a neurological etiology for nonspecific symptoms that otherwise elude explanation. Our patient presented with acute decompensated hydrocephalus upon exploratory abdominal laparoscopy for unresolving abdominal pain. The patient had an eight-month history of unexplained intermittent nausea, vomiting, and abdominal pain. These bouts increased in frequency during the weeks before acute presentation, prompting exploratory abdominal laparoscopy. The acute decompensation was managed by ventriculostomy, and cranial MRI revealed a cystic mass by the floor of the fourth ventricle. After the patient stabilized and returned to neurological baseline, suboccipital craniectomy and resection were performed. The mass was histologically identified as a neurenteric cyst. The patient was free from neurological complaints at one-year follow-up, indicating that the successful resection of the area postrema-associated neurenteric cyst resolved her previous symptoms. Thus, some intracranial lesions can masquerade as nonspecific symptoms, presenting a challenge to accurate diagnosis. PMID:25317345

    The pathogenesis of cysts that arise in the jaws is still not certain, and the underlying mechanisms of epithelial proliferation are not fully understood. Cysts of the jaw may involve a reactive, inflammatory, or neoplastic process. Cytogenetics, the study of the number and structure of chromosomes, has provided valuable information about the diagnosis, prognosis, and targeted treatment in many cancers, including oral squamous cell carcinoma. Cytogenetics can also provide information about the possible aetiology or neoplastic potential of a lesion, though to our knowledge no studies of this technique have been used for cysts in the jaws. In this pilot study we used cytogenetics in a series of 10 cysts (3 radicular, 4 dentigerous, 2 of the nasopalatine duct, and 1 dermoid). In all cases we found normal karyotypes. Further work and larger numbers are needed for a definitive study, but we can hypothesise from this pilot study that these cysts do not have cytogenetic aberrations and so have no neoplastic potential.

    The approach to incidentally noted pancreatic cysts is constantly evolving. While surgical resection is indicated for malignant or higher risk cysts, correctly identifying these highest risk pancreatic cystic lesions remains difficult. Using parameters including cyst size, presence of solid components, and pancreatic duct involvement, the 2012 International Association of Pancreatology (IAP) and the 2015 American Gastroenterological Association (AGA) guidelines have sought to identify the higher risk patients who would benefit from further evaluation using endoscopic ultrasound (EUS). Not only can EUS help further assess the presence of solid component and nodules, but also fine needle aspiration of cyst fluid aids in diagnosis by obtaining cellular, molecular, and genetic data. The impact of new endoscopic innovations with novel methods of direct visualization including confocal endomicroscopy require further validation. This review also highlights the differences between the 2012 IAP and 2015 AGA guidelines, which include the thresholds for sending patients for EUS and surgery and methods, interval, and duration of surveillance for unresected cysts.

    2014-01-01

    A 68-year-old female had a three-week history of severe low back pain radiating down the posterior left buttocks and left leg exacerbated by standing and walking. Lumbar spine MRI revealed cystic mass with similar intensity to cerebrospinal fluid located on dorsolateral left side of the sacral spinal canal inferior to the S1 pedicle. There was compression of left exiting S1 and traversing S2 nerve roots. Neurosurgery consult was requested to evaluate the cystic mass in the sacral spinal canal. After clinical evaluation, an unusually located synovial cyst was thought possible. Cyst contents were heterogeneous, suggestive of small hemorrhage and acute clinical history seemed reasonable. Left S1 and partial left S2 hemilaminectomy was performed and an epidural, partially hemorrhagic cyst was removed. There was no obvious connection to the ipsilateral L5-S1 facet joint. Pathology revealed synovial cyst, and the patient's leg pain was improved postoperatively. This synovial cyst was unusual as it had no connection with the facet joint intraoperatively and its location in the sacral canal was uncommon. PMID:24716025

    2002-03-01

    Between 1991 and 2000, seven patients presented with symptomatic pineal cysts at our hospital (6 females, 1 male). Average age was 22 years (range 4-33 years). Headache was present in 6 patients, who were subsequently operated on. A scotoma and a transient inferior visual field deficit were minor signs in two patients respectively. A Parinaud syndrome with vertical gaze paralysis was found in none. In one child, paroxysmal pupillary dilatations and contractions ('springing pupils') constituted the only signs and a conservative policy was adopted. Four patients presented with hydrocephalus and were treated by an endoscopic resection of their pineal cysts (one stereotactically, three free-hand). Two other patients presented with a prolonged history of symptoms and signs: headache alone in one, headache with discrete neurological deficits in the other. Ventricles in these two patients were not dilated and therefore an open cyst resection by infratentorial supracerebellar approach was performed. Average follow-up in the six "operated" patients was 29 months (range 12-108 months). All four patients treated by endoscopy, are symptom-free at follow-up, whereas the two who were approached by open surgery, are not. Clinical presentation, radiological evaluation and treatment modalities of pineal cysts are discussed and compared with experiences reported in the literature. It is concluded that pineal cysts in the presence of obstructive hydrocephalus are a clear indication for endoscopy with a rigid endoscope. PMID:11956936

    Introduction: The hydatid cyst is a real public health problem in Tunisia. The retrovesical localization is rare. It is considered an aberrant or ectopic location defined by the development of the parasite in the subvesical and retrovesical fat. Methods: From 2004 to 2013, 4 patients with retrovesical hydatid cyst were hospitalized and operated in the Department of Urology at the Charles Nicolle hospital of Tunis in Tunisia. The average patient age was 40.75 years (range: 23–76). Signs of bladder irritation were the most frequent presenting complaint. No cases of hydaturia were noted. The diagnosis was made on the ultrasound and the computed tomographic urography. Hydatid serology was positive for 3 patients. In 3 cases, a hydatid cyst of the liver was associated. A total cysto-pericystectomy was performed for 1 patient, for others it was partial. Results: The postoperative course was uneventful. No urinary fistula or infection of the residual cavity was observed. One patient had a retroperitoneal cyst recurrence requiring reoperation. Conclusion: Retrovesical location of hydatid cyst is rare and treatment is primarily surgical. PMID:26225181

    ABSTRACT Dentigerous Cyst/developmental cyst of benign odontogenic origin are ones that surround the crown of impacted, embedded, unerupted or developing teeth. Dentigerous cyst is second most common cyst of the oral cavity after radicular cyst. They are usually solitary in occurrence and mostly associated with the mandibular third molars. Dentigerous cysts involving impacted second premolars are rarely reported in the literatures. We present a rare case of dentigerous cyst in a 12-year-old female patient associated with an impacted mandibular second premolar. How to cite this article: Mishra R, Tripathi AM, Rathore M.

    We describe a case of sacral perineural cyst presenting with complaints of low back pain with neurological claudication. The patient was treated by laminectomy and excision of the cyst. Tarlov cysts (sacral perineural cysts) are nerve root cysts found most commonly in the sacral roots, arising between the covering layer of the perineurium and the endoneurium near the dorsal root ganglion. The incidence of Tarlov cysts is 5% and most of them are asymptomatic, usually detected as incidental findings on MRI. Symptomatic Tarlov cysts are extremely rare, commonly presenting as sacral or lumbar pain syndromes, sciatica or rarely as cauda equina syndrome. Tarlov cysts should be considered in the differential diagnosis of patients presenting with these complaints. PMID:21139800

    Epidermal cysts represent the most common cutaneous cysts. They arise following a localized inflammation of the hair follicle and occasionally after the implantation of the epithelium, following a trauma or surgery. Conventional epidermal cysts are about 5 cm in diameter; however, rare reports of cysts more than 5 cm are reported in the literature and are referred as “Giant epidermal cysts.” Epidermal cysts although common, can mimic other common benign lesions in the head and neck area. A thorough clinico-pathologic investigation is needed to diagnose these cutaneous lesions as they differ in their biologic behavior, treatment, and prognosis. We report a case of a giant epidermoid cyst in the scalp area of a young female patient which mimicked lipoma on clinical, as well as cyotological examination. We also present a brief review of epidermal cysts, their histopathological differential diagnosis, and their malignant transformation. PMID:26677303

    Background Symptomatic sacral perineural cysts are a common cause of chronic pain. Surgery is one choice for symptom relief but has a high risk of cyst recurrence and complications. As a simple and safe method to manage symptomatic sacral perineural cysts, C-arm fluoroscopy-guided fibrin gel injection may represent a new minimally invasive alternative. To evaluate the efficacy of this new method, we conducted a retrospective study of 42 patients. Methods and Findings From June 2009 to August 2012, a total of 42 patients with symptomatic sacral perineural cysts underwent C-arm fluoroscopy-guided percutaneous fibrin gel injection therapy. Patient outcomes in terms of improvements in pain and neurologic function were evaluated during a follow-up period of 13–39 months. The preoperative and postoperative pain severity were assessed according to a 10-cm visual analog pain scale, and imaging changes were evaluated by magnetic resonance imaging. We also assessed postoperative complications. Most patients experienced benefit from the procedure: twenty-five patients (59.5%) reported excellent recovery, eleven (26.2%) reported good recovery, three (7.1%) reported fair recovery, and three (7.1%) reported poor recovery. The overall effectiveness rate (excellent and good recoveries) was 85.7%. No serious postoperative complications were observed. Conclusion Percutaneous fibrin gel injection under C-arm fluoroscopy guidance could be a simple, safe and effective treatment option for symptomatic sacral perineural cysts. PMID:25706639

    The aim of this case study is to present effectiveness of percutaneous drainage as a treatment option of ruptured lung and liver hydatid cysts. A 65-year-old male patient was admitted with complicated liver and lung hydatid cysts. A liver hydatid cyst had ruptured transdiaphragmatically, and a lung hydatid cyst had ruptured both into bronchi and pleural space. The patient could not undergo surgery because of decreased respiratory function. Both cysts were drained percutaneously using oral albendazole. Povidone-iodine was used to treat the liver cyst after closure of the diaphragmatic rupture. The drainage was considered successful, and the patient had no recurrence of signs and symptoms. Clinical, laboratory, and radiologic recovery was observed during 2.5 months of catheterization. The patient was asymptomatic after catheter drainage. No recurrence was detected during 86 months of follow-up. For inoperable patients with ruptured liver and lung hydatid cysts, percutaneous drainage with oral albendazole is an alternative treatment option to surgery. The percutaneous approach can be life-saving in such cases.

    A 44-year-old male patient who had undergone augmentation penoplasty 20 years previously presented with a slowly growing penoscrotal mass. The penile mass was excised totally and the pathologic diagnosis was an epidermal cyst. Epidermal cysts are benign disorders that can occur in any part of the body. However, an epidermal cyst as a late complication of augmentation penoplasty is extremely rare. We report this case of a penile epidermal cyst that developed after augmentation penoplasty.

    Giardia cyst-like objects detected by immunofluorescence in chlorinated water samples often cannot be positively identified by their morphological appearance. To determine the effect of chlorine on cyst immunofluorescence and morphology, Giardia lamblia cysts were exposed to chlorine for 48 h. The majority of cysts exposed to chlorine concentrations of 1 to 11 mg/liter at 5 and 15 degrees C lost their internal morphological characteristics necessary for identification, but most of them were still detectable by immunofluorescence.

    Results of treatment of 31 hepatic hydatid cysts in 28 patients were analyzed. The size of the s ranged from 3 to 25 cm. In 26 cases the cysts contained flive es, in 2 cases they were suppurated after US-assisted intraoperative puncture. Simple hydatid cysts (type I by M. Milcevic) were diagnosed in 24 patients (solitary--in 22, multiple--in 2), solitary cysts of type II--in 2 patients. In 23 cases aspiration-catheter treatment with complete removal of chitin membrane by one-stage (4) or two-stage (19) methods was performed. After removal of chitin membrane in 3 patients lateral fistula between spurious cysts cavities and peripheral branches of intrahepatic bile ducts were revealed which spontaneously. Glue composition "Rabrom" was used in 2 cases for closure of the residual cavity. In 4 patients who had cysts less 6 cm in size puncture irrigation of chitin cavity with 30% NaCl (PAIR technique) without it removal was performed. In one patient transcutaneous catheter (PAIR-PD technique) was used for irrigation of the cyst larger than 6 cm. The duration of two-stage aspiration-catheter treatment with removal of chitin membrane was 25.6 +/- 9.6 days. In moderate calcinosis of the fibrous membrane and bile fistulas period of hospitalization was 34 +/- 8.1 days. Treatment with PAIR and PAIR-PD took 1 and 3 days respectively. Complications of percutaneous methods were regarded as mild: hyperthermia (12), right-sided hydrothorax (6), subcapsular hematoma (1), urticaria (1). All the complications were treated conservatively and with US-assisted punctures. Long-term (from 6 months to 9 years) results of treatment were followed up in 26 patients: there were no recurrences. Suppuration of the residual cavity 6 months after the glue occlusion was eradicated by transcutaneous catheter drainage. One lethal outcome was not associated with complications of aspiration-catheter treatment. Both methods of transcutaneous treatment of hepatic hydatid cysts are effective and safe. A hypertonic solution of NaCl I produces a reliable antiscolecidal and sclerosis effect. PMID:12389500

    The neurenteric cyst is a rare developmental lesion arising as a result of persistence of the neurenteric canal. It usually presents in the second and third decade. Lesions occurring in children are rare. Majority of the cases presented with signs of spinal cord involvement. This is a rare case of neurenteric cyst in an infant who presented with a presacral mass. A nine-month-old female had an antenatally diagnosed sacrococcygeal lesion. Radiology suggested a diagnosis of sacrococcygeal teratoma. Histology was typical of a neurenteric cyst. We report this case to create awareness about this rare cystic lesion and inclusion of this entity in the differential diagnosis of cystic masses in children at this location. PMID:26500914

    Rathke cleft cysts (RCCs) are benign cystic lesions of the sellar and suprasellar region that are asymptomatic in most cases. Occasionally, compression of the optic pathway and hypothalamo-pituitary structures may cause clinical symptoms, such as headaches, visual deficits and endocrinopathies. Acute presentation caused by hemorrhage into an RCC have been described in the literature, and the term "Rathke cleft cyst apoplexy" has been coined. We present the case of a 32-year-old man with acute onset of meningitis-type symptoms and imaging findings resembling hemorrhagic pituitary tumor apoplexy. In retrospect, clinical symptoms, intraoperative appearance, and histologic examination were compatible with the diagnosis of nonhemorrhagic rupture of an RCC. Thus, the clinical presentation of "Rathke cleft cyst apoplexy" is not necessarily caused by hemorrhage. PMID:23696292

    We report the case of a 15-month-old boy who presented with a mass lesion of the right upper eyelid that had been present since birth and had slowly enlarged over the last 3 months. The lesion had minimal surrounding erythema simulating the appearance of a chalazion. Intraoperatively the lesion was noted to be firmly adherent to the underlying tarsus. The lesion was excised completely through an eyelid crease approach leaving the tarsus intact. The histopathology was consistent with dermoid cyst. To our knowledge, this is the third case of a tarsal dermoid cyst reported in the literature. Dermoid cyst should be included in the differential diagnosis of eyelid mass lesions, and particulary differentiated from a chalazion to avoid mismanagement that may lead to scarring, recurrence and inflammation. The excision of these lesions sparing the underlying tarsus can be possible. PMID:26586987

    An intracranial epidermoid cyst was diagnosed in a Haflinger gelding aged 12 years suffering from episodes of neurological disturbance, apathy and fever. The extracerebral cyst was located in the region of the tentorium cerebelli and measured 9 x 8 x 5 cm. It displaced the cerebral hemispheres anteriorly and compressed the cerebellum and brainstem underneath. Histologically, the cyst was lined by keratinizing, stratified squamous epithelium and contained keratin scales, debris, focal haemorrhages, and degenerating inflammatory cells. The epithelium was supported by a vascularized fibrous capsule that firmly adhered to the dura mater. Multifocal haemorrhages and moderate lymphohistiocytic infiltrations were present in the capsule. The basement membrane was disrupted focally, and single or clustered cytokeratin-positive epithelial cells were detected in the fibrous capsule, suggesting a possible transition to malignancy.

    Adrenal cysts are rare, and their clinical management remains controversial. We report a case involving an adrenal cyst with a complicated appearance on radiological studies. Unenhanced computed tomography revealed a unilocular, noncalcified, hypoattenuating mass with a thin wall in the left adrenal gland. The lesion gradually increased in size from 10 to 50?mm at two-year follow-up. On contrast-enhanced magnetic resonance imaging, a mural nodule with contrast enhancement was observed. The entire adrenal gland was excised en bloc via a lateral transperitoneal laparoscopic approach without violating the principles of surgical oncology. The pathological diagnosis was an adrenal pseudocyst. Laparoscopic adrenalectomy is a safe option for the treatment of complex adrenal cysts, while maintaining the benefits of minimal invasiveness.

    A life threatening complication in the course of routine sedation in a 5 year old child is reported in a case study. A retention cyst of the epiglottis was found to be responsible for obstruction of the larynx leading to acute apnea. The patient history revealed recurrent episodes of stridor previously diagnosed and treated as acute laryngotracheobronchitis as well as border line psychomotoric retardation. Cerebral magnetic resonance imaging was performed for neuroradiological evaluation. After administration of sedation the child presented with stridor and acute apnea. Emergency orotracheal intubation could prevent tracheotomy but was complicated by the unexpected presence of a tumor at the base of the tongue. Further evaluation revealed a large epiglottic cyst. After endoscopic removal of the cyst no further episodes of apnea or stridor were noted. PMID:9466231

    OBJECT High-resolution magnetic resonance imaging (MRI) can distinguish between intraneural ganglion cysts and paralabral (extraneural) cysts at the glenohumeral joint. Suprascapular intraneural ganglion cysts share the same pathomechanism as their paralabral counterparts, emanating from a tear in the glenoid labrum. The authors present 2 cases to demonstrate that the identification and arthroscopic repair of labral tears form the cornerstone of treatment for intraneural ganglion cysts of the suprascapular nerve. METHODS Two patients with suprascapular intraneural ganglion cysts were identified: 1 was recognized and treated prospectively, and the other, previously reported as a paralabral cyst, was identified retrospectively through the reinter-pretation of high-resolution MR images. RESULTS Both patients achieved full functional recovery and had complete radiological involution of the intraneural ganglion cysts at the 3-month and 12-month follow-ups, respectively. CONCLUSIONS Previous reports of suprascapular intraneural ganglion cysts described treatment by an open approach to decompress the cysts and resect the articular nerve branch to the glenohumeral joint. The 2 cases in this report demonstrate that intraneural ganglion cysts, similar to paralabral cysts, can be treated with arthroscopic repair of the glenoid labrum without resection of the articular branch. This approach minimizes surgical morbidity and directly addresses the primary etiology of intraneural and extraneural ganglion cysts. PMID:26323813

    AIM: To determine the immunocytochemical pattern of expression of transforming growth factor (TGF) alpha, epidermal growth factor (EGF), and TGF beta in the three most common types of odontogenic jaw cyst. METHODS: Growth factor expression was detected in paraffin wax sections of odontogenic cysts (27 odontogenic keratocysts, 10 dentigerous cysts, and 10 radicular cysts) using a streptavidin-biotin peroxidase technique with monoclonal antibodies directed against TGF alpha (clone 213-4.4) and TGF beta (clone TB21) and a polyclonal antibody directed against EGF (Z-12). RESULTS: The epithelial linings of all cysts showed reactivity for TGF alpha which was mainly localised to basal and suprabasal layers. Odontogenic keratocyst linings expressed higher levels of TGF alpha than those of dentigerous and radicular cysts, with 89% (24/27) of odontogenic keratocysts exhibiting a strong positive reaction compared with 50% (five of 10) of dentigerous and radicular cysts, respectively. EGF reactivity was similar in all cyst groups, weaker than that for TGF alpha and predominantly suprabasal. TGF alpha and EGF were also detected in endothelial cells, fibroblasts and inflammatory cells within the cyst walls. The most intense TGF beta staining in odontogenic cysts was extracellular within the fibrous tissue capsules, irrespective of cyst type. CONCLUSIONS: These results, together with previous studies of EGF receptor, indicate differential expression of TGF alpha, EGF and their common receptor between the different types of odontogenic cyst, suggesting that these growth factors (via autocrine or paracrine, or both, pathways) may be involved in their pathogenesis.

  2. Histologic and immunohistochemical characteristics of cutaneous cysts in Goltz-Gorlin syndrome: clues for differentiation of nonsyndromic cysts.

    PubMed

    2014-11-01

    Goltz-Gorlin syndrome presents with multiple basal cell carcinomas, odontogenic keratocysts, and cutaneous cysts, among other manifestations. The cutaneous cysts have been described as both epidermoid cysts and keratocysts but were not further characterized. Light microscopic examinations were made on 23 cutaneous cysts in 4 patients associated with Goltz-Gorlin syndrome located on extremities, face, trunk, palms, and soles and compared with nonsyndromic vellus hair cysts, steatocystomas, and hybrid cysts. Twenty-one of the syndromic cysts revealed alternating infundibular-like and steatocystoma-like squamous epitheliums in varying proportions. The cysts were lined by both smooth and corrugated squamous epithelium. The horny layer was composed by alternating areas of thin, lamellate, and compact eosinophilic keratin. Only 2 cases showed an exclusive steatocystoma-like type of epithelium very similar to odontogenic keratocysts. Sebaceous glands and follicular structures were absent. There were no differences between palmar and plantar cysts and other anatomic locations. The ultrastructural findings in syndromatic cysts confirmed variable expression of keratohyalin granules. Only 3 of 6 cases of nonsyndromic hybrid cysts showed overlapping features with syndromic cysts. Immunohistochemical profiling of keratin, involucrin, filaggrin, loricrin, and BCL-2 expression in syndromatic cysts showed exclusive positivity of K19 and continuous staining for BCL-2. In summary, 2 types of cutaneous cysts are characteristic of Goltz-Gorlin, irrelevant of their anatomic location, namely steatocystoma-like and more frequently hybrid-like. The diagnosis of syndromic hybrid-like cysts should be considered whenever infundibular and steatocystoma differentiation alternate and overlap. Altogether, these findings in epithelial cysts may raise the suspicion of Goltz-Gorlin as an underlying cause. PMID:24698937

    Vermian epidermoid cyst developing in the fourth ventricle is very rare. We report a case observed in a 24-year-old man, who presented severe headache, dizziness and a blurred vision following head injury. Examination revealed a discrete gait disturbance. Cerebral CT-scan showed a large hypodense lesion of the posterior fossa without contrast enhancement. MRI demonstrated the vermian location of this lesion which displaced the roof of the fourth ventricle upward and the brainstem forward. A suboccipital approach allowed total removal of a well-encapsulated epidermoid cyst, non adherent to the floor of the fourth ventricle. The postoperative course was uneventful. PMID:16609662

We report a case of a 38 year old male patient who presented to our department with neck and left superior limb pain associated with palmar muscle atrophy and Horner's syndrome. Radiological investigations suggested the diagnosis of hydatid cyst of the left lung apex which was confirmed by surgical excision and pathological examination of the lesion. This case highlights an uncommon etiology of Pancoast syndrome which might mislead physicians in their practice. PMID:23717731

    We report the case of a 50-year-old woman who presented with eight digital myxoid cysts (DMCs) involving the fingers of both hands. They developed within 12 months of the patient starting a job that involved pushing a garment into an embroidery mould, thus exerting a downward force on the fingertips. The pressure exerted from this force could have potentially damaged the joint synovial capsule, leading to rupture and loss of synovial gel, thus inducing myxoid cysts. This case suggests that DMCs may be related to occupation, and to our knowledge, this is only the second reported case of occupationally induced DMCs. PMID:16681589

    The combinations of genetic alterations that cooperate with von Hippel–Lindau (VHL) mutation to cause clear cell renal cell carcinoma (ccRCC) remain poorly understood. We show that the TP53 tumour suppressor gene is mutated in approximately 9% of human ccRCCs. Combined deletion of Vhl and Trp53 in primary mouse embryo fibroblasts causes proliferative dysregulation and high rates of aneuploidy. Deletion of these genes in the epithelium of the kidney induces the formation of simple cysts, atypical cysts and neoplasms, and deletion in the epithelia of the genital urinary tract leads to dysplasia and tumour formation. Kidney cysts display a reduced frequency of primary cilia and atypical cysts and neoplasms exhibit a pro-proliferative signature including activation of mTORC1 and high expression of Myc, mimicking several cellular and molecular alterations seen in human ccRCC and its precursor lesions. As the majority of ccRCC is associated with functional inactivation of VHL, our findings suggest that for a subset of ccRCC, loss of p53 function represents a critical event in tumour development.

    Background The category B agent of bioterrorism, Entamoeba histolytica has a two-stage life cycle: an infective cyst stage, and an invasive trophozoite stage. Due to our inability to effectively induce encystation in vitro, our knowledge about the cyst form remains limited. This also hampers our ability to develop cyst-specific diagnostic tools. Aims Three main aims were (i) to identify E. histolytica proteins in cyst samples, (ii) to enrich our knowledge about the cyst stage, and (iii) to identify candidate proteins to develop cyst-specific diagnostic tools. Methods Cysts were purified from the stool of infected individuals using Percoll (gradient) purification. A highly sensitive LC-MS/MS mass spectrometer (Orbitrap) was used to identify cyst proteins. Results A total of 417 non-redundant E. histolytica proteins were identified including 195 proteins that were never detected in trophozoite-derived proteomes or expressed sequence tag (EST) datasets, consistent with cyst specificity. Cyst-wall specific glycoproteins Jacob, Jessie and chitinase were positively identified. Antibodies produced against Jacob identified cysts in fecal specimens and have potential utility as a diagnostic reagent. Several protein kinases, small GTPase signaling molecules, DNA repair proteins, epigenetic regulators, and surface associated proteins were also identified. Proteins we identified are likely to be among the most abundant in excreted cysts, and therefore show promise as diagnostic targets. Major Conclusions The proteome data generated here are a first for naturally-occurring E. histolytica cysts, and they provide important insights into the infectious cyst form. Additionally, numerous unique candidate proteins were identified which will aid the development of new diagnostic tools for identification of E. histolytica cysts. PMID:22590659

    The life cycle of dinoflagellates of the genus Alexandrium includes sexual reproduction followed by the formation of a dormant hypnozygote cyst, which serves as a resting stage. Negatively buoyant cysts purportedly fall to the benthos where they undergo a mandatory period of quiescence. Previous reports of cysts in the surficial sediments of the Gulf of Maine, where Alexandrium blooms are well documented, show a broad distribution of cysts, with highest concentrations generally in sediments below 100 m depth. We report here an exploration of cysts suspended in the water column, where they would be better positioned to inoculate springtime Alexandrium populations. During cruises in February, April, and June of 2000, water samples were collected at depths just off the bottom (within 5 m), at the top of the bottom nepheloid layer, and near the surface (1 m) and examined for cyst concentrations. Suspended cysts were found throughout the Gulf of Maine and westernmost Bay of Fundy. Planktonic cyst densities were generally greater in near-bottom and top of the bottom nepheloid layer samples than in near-surface water samples; densities were of the order of 10 2 cysts m -3 in surface waters, and 10 2-10 3 cysts m -3 at near-bottom depths. Temporally, they were most abundant in February and least abundant in April. Reports by earlier workers of cysts in the underlying sediments were on the order of 10 3 cysts cm -3. We present calculations that demonstrate the likelihood of cyst resuspension from bottom sediments forced by swell and tidal currents, and propose that such resuspended cysts are important in inoculating the seasonal bloom. We estimate that suspended cysts may contribute significantly to the annual vegetative cell population in the Gulf of Maine.

    Hydatid cysts commonly affect liver and lung but it can also affect the brain in rare cases. We report a case of 22 year female with history of headache for one and half years. Intracranial hydatid cyst was diagnosed on computed tomography scan and magnetic resonance imaging. The cyst was delivered without rupture using hydrostatic dissection followed by post-operative anthelminthic medication. Surgery remains to be the standard management. Amongst the surgical techniques described, Dowling's technique is the most acceptable. However, care must be taken in to avoid rupture of the cyst peroperatively which can result in subsequent complications and recurrence. Albendazole and corticosteroids can be used as adjunct to surgical treatment in selective cases. PMID:24174780

    Gastric duplication cysts are rare variety of gastrointestinal duplications. Sometimes they may present with complications like hemorrhage, infection, perforation, volvulus, intussusception and rarely neoplastic changes in the gastric duplication cyst. We present one and half year old male child who developed sudden abdominal distension with pain and fever for two days. Ultrasound revealed a cystic mass in the hypochondrium and epigastric regions. On exploration an infected and perforated gastric duplication cyst was found. Surgical excision of most part of cyst wall with mucosal stripping of the rest was performed. Histopathology confirmed the diagnosis of gastric duplication cyst. Early surgical intervention can result in good outcome. PMID:22953249

    Lumbosacral perineural cysts are formed by the arachnoid membrane of the nerve root at the lumbosacral level. Most of these cysts are asymptomatic and are found incidentally during computed tomography (CT) or magnetic resonance imaging (MRI) for other causes of chronic lower back pain. This type of cyst requires a differential diagnosis to distinguish it from other causes of radiating pain and neurological symptoms. In the present case, a symptomatic lumbosacral perineural cyst was found, and pain relief was achieved by non-surgical treatment. A lumbosacral perineural cyst was identified from a differential diagnosis of a lumbar disc disorder that presented as radiating pain and neurological symptoms. PMID:22679550

    Baker's cyst is a distension of the gastrocnemius-semimembranosus bursa of the knee, which communicates with the posterior portion of the joint capsule. Baker's cyst is commonly located in the inferomedial or superficial layers of the knee joint and rarely extends laterally or proximally. Complications of Baker's cysts are dissection, rupture, pseudothrombophlebitis, leg ischemia, nerve entrapment, and compartment syndrome. However, hematomas in the Baker's cyst have not been reported in Korea. We report a rare case of hematoma in the Baker's cyst with subfascial extension into the calf. The hematoma was demonstrated by magnetic resonance imaging and removed by mass excision. PMID:25505709

    Epidermoid cysts are benign slow growing extra-axial tumours that insinuate between brain structures, while their occurrences in intra-axial or intradiploic locations are exceptionally rare. We present the clinical, imaging, and pathological findings in two patients with atypical epidermoid cysts. CT and MRI findings for the first case revealed an intraparenchymal epidermoid cyst that demonstrated no restricted diffusion. The second case demonstrated an aggressive epidermoid cyst that invaded into the intradiploic spaces, transverse sinus, and the calvarium. The timing of ectodermal tissue sequestration during fetal development may account for the occurrence of atypical epidermoid cysts. PMID:25667778

    Pilar cysts are common squamous-lined cysts that typically occur on the scalp. They are believed to arise from the isthmus of anagen hairs or from the sac surrounding catagen and telogen hairs. The authors describe a rare case of a pilar cyst with prominent ductal differentiation, presumably of eccrine derivation. Sweat duct differentiation has been described in a myriad of cutaneous neoplasms and rarely within epidermoid cysts. The authors could only find one other case in the literature describing a pilar cyst with sebaceous and apocrine differentiation. The clinicopathologic findings are described here. PMID:26588334

    2016-02-01

    We report a patient with a giant, calcified colloid cyst in the left lateral ventricle. Colloid cysts are slow growing, benign lesions, commonly originating in the roof of the anterior third ventricle near the foramen of Monro. Many colloid cysts are small lesions which are either discovered incidentally or cause headache, visual changes, memory deficits, and/or syncope. Giant colloid cysts are rare. A 40-year-old man presented with a month long history of worsening headaches and was found to have a multiloculated 5cm intraventricular mass with an anterior hyperdensity, suggestive of calcification, arising within the lateral ventricles. He underwent an interhemispheric transcallosal approach for resection of the mass. The pathology was consistent with a giant colloid cyst with calcification in the anterior cyst wall. Giant, calcified mass is a rare presentation of colloid cyst. Although rare, this diagnosis remains an important consideration in the differential diagnosis of any calcified, cystic intraventricular mass. PMID:26358201

    Acetabular labral tears are a known cause of hip pain in the young, active patient. Labral tears can be due to trauma, femoroacetabular impingement, capsular laxity, dysplasia, and degenerative pathology. Paralabral cysts are relatively common in association with labral tears of the hip, with cysts seen on magnetic resonance imaging studies in as many as 50% to 70% of patients with labral tears. In some cases the cysts can become sizeable and cause neurovascular compression. Nonoperative interventions for the management of paralabral cysts in the shoulder and knee have shown high recurrence rates. In the shoulder and knee, arthroscopic debridement of paralabral cysts has shown good results with lower recurrence rates and resolution of neurovascular function. In the hip there is limited literature regarding surgical management of paralabral cysts. We present a surgical technique for arthroscopic decompression of acetabular paralabral cysts combined with labral repair. PMID:25973371

    INTRODUCTION The differential diagnosis of hepatic cystic lesions is a challenging process especially in case of hepatic rhabdomyosarcoma (HRMS) presenting as hepatic cyst. PRESENTATION OF CASE We introduce our experience with a case of HRMS in a 3-year-old female patient who was misdiagnosed to have type IV-A choledochal cyst and definitive correct diagnosis was reached after the pathological and immunohistochemical examination of the surgically resected lesion. This case presentation is followed by important practical messages to hepatobiliary surgeons regarding HRMS. DISCUSSION HRMS is a rare pediatric tumor. Jaundice is the most common presentation of HRMS followed by abdominal pain and vomiting. Great effort is needed to differentiate the tumor from choledochal cyst and infectious hepatitis. Through evaluation using available imaging studies together with clinical anticipation is mandatory for establishing the correct diagnosis. CONCLUSION Differentiation of HRMs from choledochal cyst mandates through evaluation and clinical anticipation. HRMS should be suspected in any child with obstructive jaundice. Once diagnosis is established, multidisciplinary treatment is the best management strategy and it has proved better surgical outcome and long term survival. PMID:24636980

    Symptomatic Tarlov cysts typically cause chronic pelvic and lower extremity pain and sacral nerve root radiculopathy. Historically, open surgical treatment involved significant patient morbidity, particularly postoperative cerebrospinal fluid (CSF) leaks and infection. These CSF leaks often required multiple surgical procedures to seal. Over the past 20 years, there have been two or three isolated case reports of computed tomography (CT)-guided needle aspirations that offered limited evidence of treatment efficacy and safety. Some have reported high rates of postprocedure aseptic meningitis that were not well explained. These poor results dissuaded physicians from caring for these patients. As a group these patients are usually treated dismissively and told their cysts are asymptomatic and their pain must be coming from somewhere else. Many of them have had an unnecessary discectomy or a spinal fusion, and when these procedures did not relieve their pain they were told they are a "failed back patient." We have treated more than a hundred patients with symptomatic Tarlov cysts by CT fluoroscopic-guided needle aspiration and fibrin injection and have had excellent results with no meaningful complications and never a case of aseptic meningitis. We believe this is a safe, highly effective first-line treatment for symptomatic Tarlov cysts. PMID:21500136

    Pseudoachondroplasia (PSACH) is a spondylo-epi-metaphyseal dysplasia characterised by disproportionate short stature, generalised ligamentous laxity and precocious osteoarthritis. Autosomal dominant inheritance has been demonstrated in many families. The present case was normal at birth. By 3 years of age his height has fallen below the 5th percentile. At 6 1/2 years of age he was 99 cm tall (-3.5 SD), and he had bowing of the lower extremities and some limitations of movements at the elbows and knees. Radiographs showed features of PSACH. Kypho-scoliosis appeared later on with anterior beaking of the vertebrae. Cerebral CT scan showed a very large frontal cyst communicating with the IIIrd ventricle. RMI confirmed the frontal cyst and showed dilatation of the IIIrd ventricle and of the occipital horns of the lateral ventricles, and a right frontal parietal hemispheric atrophy. At 26 years of age he complained of pain in the knees, swallowing difficulties, and vertigo. Renal ultrasonographic examination showed a large cortical cyst of the right kidney and smaller cysts in both kidney. PMID:12150213

    Localization of epidermoid cysts to the pineal region is rare. The 7-year-old boy now reported presented with an 18-month history of progressive ataxia. CT and MRI scans demonstrated a 2.5x2.5 cm cyst at the pineal region with obstructive hydrocephalus. At surgery via an occipital transtentorial approach, a characteristic "pearly tumour" was encountered, and complete resection was achieved. We present the management of this child with pineal region epidermoid cyst and review 11 cases reported in the literature since 1968. In all, 8 of the 12 patients were males. The age at the time of diagnosis ranged from 7 years to 69 years. Parinaud's syndrome and hydrocephalus are the most common presenting findings. All but 1 patient underwent direct surgical resection; 1 had stereotactic decompression. Surgical treatment brought about complete resolution of the presenting symptoms and signs in 10 of the 12 cases. One patient had persistent upgaze palsy. One patient died from progression of the pineal region mass. This patient presented with hemiparesis, which is a marker of clinical aggressiveness. The authors advocate direct surgical attack as opposed to stereotactic diagnosis and aspiration to: (1) obtain maximal resection and thereby limit the potential for recurrence and delayed complications of the cyst; (2) possibly avoid shunt placement in patients who present with hydrocephalus; and (3) decrease the likelihood of sampling error.

    During the 20th century, allograft implantation waned in popularity as a clinical activity. Reports appeared in the literature describing several small series of patients in whom bone was obtained from amputation specimens or recently deceased individuals. The concept of bone banking became a reality during and after World War II when the National Naval Tissue Bank was established in Bethesda and a number of small banks sprang up in hospitals throughout the world. Small fragments, either of cortical or medullary bone, from these banks were used heterotopically to augment spinal fusions, to implant into cyst cavities, or to serve as a scaffolding for repair of non- or delayed union of fractures of the long bones.

    Giardia lamblia is a waterborne parasite that causes an intestinal infection, known as giardiasis, and it is found not only in countries with inadequate sanitation and unsafe water but also streams and lakes of developed countries. Simple, sensitive, and rapid detection of this pathogen is important for monitoring of drinking water. Here we present a cost-effective and field portable mobile-phone based fluorescence microscopy platform designed for automated detection of Giardia lamblia cysts in large volume water samples (i.e., 10 ml) to be used in low-resource field settings. This fluorescence microscope is integrated with a disposable water-sampling cassette, which is based on a flow-through porous polycarbonate membrane and provides a wide surface area for fluorescence imaging and enumeration of the captured Giardia cysts on the membrane. Water sample of interest, containing fluorescently labeled Giardia cysts, is introduced into the absorbent pads that are in contact with the membrane in the cassette by capillary action, which eliminates the need for electrically driven flow for sample processing. Our fluorescence microscope weighs ~170 grams in total and has all the components of a regular microscope, capable of detecting individual fluorescently labeled cysts under light-emitting-diode (LED) based excitation. Including all the sample preparation, labeling and imaging steps, the entire measurement takes less than one hour for a sample volume of 10 ml. This mobile phone based compact and cost-effective fluorescent imaging platform together with its machine learning based cyst counting interface is easy to use and can even work in resource limited and field settings for spatio-temporal monitoring of water quality.

    Although laparoscopic fenestration has become an established treatment in symptomatic liver cyst patients in the recent years, the success of surgical treatment cannot only be evaluated by post-operative morbidity and mortality. Therefore, the aim of this study was to analyze the safety of laparoscopic fenestration of non-parasitic liver cysts and to assess the impact of this therapy on patients' quality of life. A total of 43 patients who underwent laparoscopic fenestration of non-parasitic liver cysts at our center were included in this study. Post-operative course was assessed and patients' quality of life was evaluated before surgery and at present time using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core-30 (QLQ C-30). The results were that, post-operative morbidity and mortality rates were 0%. After a median follow-up of 49 months (19-97 months) the recurrence rate was 11.1% for simple liver cysts (SLC) and 42.9% for polycystic liver disease (PCLD). Thirty-one out of 43 patients (72.1%) completed the EORTC C-30 questionnaire. There was highly significant post-operative improvement in global health status (p < 0.001) as well as in physical (p = 0.002), role (p = 0.004), emotional (p = 0.003) and social (p = 0.001) functioning. Furthermore, a significant reduction of symptoms could be shown for pain (p < 0.001), nausea and vomiting (p = 0.001), appetite loss (p = 0.006), insomnia (p = 0.04) and fatigue (p = 0.025). To conclude, laparoscopic fenestration of symptomatic non-parasitic liver cysts is a safe procedure with good long-term results and the patients' benefit of this intervention is excellent as shown by highly significant improvement in patients' quality of life.

    Background and aims. Odontogenic cysts and tumors have a wide spectrum of clinical characteristics that lead to the different management strategies. Since definite diagnosis is difficult in some cases, it has been suggested that CD56 may be a candidate marker for definitive diagnosis of some odontogenic tumors. The present study was designed to examine CD56 expression in lesions with histopathological similarities. Materials and methods. In this cross-sectional, analytical study the subjects were 22 ameloblastomas, 13 dentigerous cysts, 10 keratocystic odontogenic tumors (KCOT), 4 adenomatoid odontogenic tumors (AOT), 3 orthokeratinized odonto-genic cysts, 3 calcifying odontogenic cysts (COC) and one glandular odontogenic cyst (GOC). All the samples were examined for CD56 immunoreactivity. Data were analyzed using chi-square test. Results. Twenty cases (91%) of ameloblastomas, 3 (75%) AOT, 4 (40%) KCOT and one case of GOC were positive for CD56. None of the dentigerous cysts, COC and orthokeratinized odontogenic cysts was CD56-positive. There was a significant difference in the CD56 expression between ameloblastoma and dentigerous cyst, as well as COC. Also, KCOT showed significantly higher expression than orthokeratinized odontogenic cyst. Conclusion. In this study CD56 expression was limited to the odontogenic tumors and more aggressive cystic lesions. This marker can be a useful aid for distinguishing cysts and tumors from similar lesions.

    Contents A total of 73 bitches with ovarian cysts were ovariohysterectomized. Cysts were characterized by gross pathology and endocrine parameters. Therefore, oestradiol-17ß and progesterone concentrations were assessed in cyst-fluid and corresponding blood plasma in each bitch. Our data demonstrated that multiple cysts were often present in a single individual (82%) and that cysts were commonly found on both ovaries (77%). The number of cysts per individual varied from 1 to 35. Most cysts were small in size (range 0.2–4.0 cm in diameter). No cyst was found to produce solely oestradiol-17ß or progesterone. Plasma levels of oestradiol-17ß and progesterone for a given individual were positively correlated with levels of these same hormones in their cyst-fluid (r = 0.334 and p = 0.001 for oestradiol-17ß; r = 0.419 and p < 0.001 for progesterone). Our study is the first to provide a comprehensive evaluation of the gross pathology and endocrinology of ovarian cysts in a larger number of bitches. PMID:24698026

  17. Alexandrium minutum resting cyst distribution dynamics in a confined site

    The life cycle of the toxic dinoflagellate Alexandrium minutum consists of an asexual stage, characterized by motile vegetative cells, and a sexual stage, a resting cyst that once formed remains dormant in the sediment. Insight into the factors that determine the distribution and abundance of resting cysts is essential to understanding the dynamics of the vegetative phase. In investigations carried out between January 2005 and January 2008 in Arenys de Mar harbor (northwestern Mediterranean Sea), the spatial and temporal distribution patterns of A. minutum resting cysts and of the sediments were studied during different bloom stages of the vegetative population. Maximum cyst abundance was recorded mainly in the innermost part of the harbor while the lowest abundance always occurred near the harbor entrance, consistent with the distribution of silt-clay sediment fractions. The tendency of cysts in sediments to increase after bloom periods was clearly associated with new cyst formation, while cyst abundance decreased during non-bloom periods. Exceptions to this trend were observed in stations dominated by the deposition of coarse sediments. High correlation between the presence of cysts and clays during non-bloom periods indicates that cysts behave as passive sediment particles and are influenced by the same hydrodynamic processes as clays. In Arenys de Mar, the main physical forcing affecting sediment resuspension is the seiche, which was studied using in situ measurements and numerical models to interpret the observed distribution patterns. During non-bloom periods, cyst losses were smaller when the seiche was more active and at the station where the seiche-induced current was larger. Thus, seiche-forced resuspension appears to reduce cyst losses by reallocating cysts back to the sediment surface such that their burial in the sediment is avoided. The observed vertical profiles of the cysts were consistent with this process.

    Inactivation of Giardia lamblia and Giardia muris cysts was compared by using an ozone demand-free 0.05 M phosphate buffer in bench-scale batch reactors at 22 degrees C. Ozone was added to each trial from a concentrated stock solution for contact times of 2 and 5 min. The viability of the control and treated cysts was evaluated by using the C3H/HeN mouse and Mongolian gerbil models for G. muris and G. lamblia, respectively. The resistance of G. lamblia to ozone was not significantly different from that of G. muris under the study conditions, contrary to previously reported data that suggested G. lamblia was significantly more sensitive to ozone than G. muris was. The simple Ct value for 2 log unit inactivation of G. lamblia was 2.4 times higher than the Ct value recommended by the Surface Water Treatment Rule. PMID:8285675

    Toxoplasma gondii infects up to one third of the world’s population. A key to the success of T.gondii is its ability to persist for the life of its host as bradyzoites within tissue cysts. The glycosylated cyst wall is the key structural feature that facilitates persistence and oral transmission of this parasite. We have identified CST1 (TGME49_064660) as a 250 kDa SRS (SAG1 related sequence) domain protein with a large mucin-like domain. CST1 is responsible for the Dolichos biflorus Agglutinin (DBA) lectin binding characteristic of T. gondii cysts. Deletion of CST1 results in a fragile brain cyst phenotype revealed by a thinning and disruption of the underlying region of the cyst wall. These defects are reversed by complementation of CST1. Additional complementation experiments demonstrate that the CST1-mucin domain is necessary for the formation of a normal cyst wall structure, the ability of the cyst to resist mechanical stress and binding of DBA to the cyst wall. RNA-seq transcriptome analysis demonstrated dysregulation of bradyzoite genes within the various cst1 mutants. These results indicate that CST1 functions as a key structural component that reinforces the cyst wall structure and confers essential sturdiness to the T. gondii tissue cyst.

  1. Non-communicating supratentorial subarachnoid cysts

    The clinical and radiological features and operative treatment of six patients with supratentorial subarachnoid cysts are reviewed. Five were adults aged 37 to 57 years and the other a male infant, aged 8 months. Three patients presented with epilepsy and hemiparesis, one with epilepsy without signs, another as Parkinsonian syndrome, and the infant with hydrocephalus. Diagnosis was revealed at operation in four cases, in one case by ventriculography, and in one case the lesion was strongly suspected on angiographic appearances. Surgical treatment is highly effective, since the cystic lesion is benign in nature, but recurrence of symptoms is not unusual and repeated evacuation of the cyst may be required. It is, therefore, considered essential to conduct a prolonged and careful follow-up. Images PMID:4539639

    A rare cause of intra-abdominal obstruction, mesenteric cysts derive from lymphatic tissue. The differential diagnosis should include mesenteric cyst when the patient presents with a history of multiple episodes of partial small-bowel obstruction or with an asymptomatic abdominal mass. A year-old girl was brought to the Family Practice Center with episodic, sharp, nonradiating, left-sided, mid-upper-abdominal pain. Examination indicated a possible diagnosis of mesenteric adenitis. Due to variation in the signs and symptoms of the condition, it appears that the use of ultrasonography is the most effective, nonoperative method of evaluation. Ultrasonography appears to be the most effective, nonoperative method of evaluation. Surgery is the only definitive diagnostic and therapeutic modality. PMID:2708094

    Botryoid Odontogenic cyst (BOC) originally described by Weathers and Waldron (1973) is a variant of a lateral periodontal cyst characterized by macroscopic and microscopic multilocular growth pattern. We report a case of BOC in a 21-year-old male patient. Orthopantamogram revealed a multilocular radiolucency extending from 43 to 47. The histological examination of incisional biopsy revealed a thin 2-4 layered non keratinised epithelium without rete ridges resembling a reduced enamel epithelium with few localised plaque like thickenings and occasional mural bulges. These features were suggestive of BOC. The excisional biopsy revealed histological features similar to those of incisional biopsy except for the presence of 5-6 epithelial follicles with outer columnar cells and inner stellate reticulum like cells. CD56 and calretinin immunohistochemical staining (IHC) was done. This paper highlights the unusual appearance of follicles in BOC with differential diagnosis and IHC staining characteristics.

    Pulmonary echinococcosis (hydatid disease) is not rare in endemic regions. In Poland it is rare, seen mainly in subjects returning from endemic areas. The intermediate host includes a variety of mammals-sheep, cows, and also humans. The definite host is the dog and is the main source of ova. A case of a 52 year old male is presented who lived in Argentina for a few years. Radiological examination disclosed two pulmonary cysts. Additionally one was also present in the spleen. The diagnosis was made basing of findings form radiological examinations. CT-scan, and serological studies. It was further confirmed during the surgical removal of the affected lung parenchyma. Leaving the spleen cysts is a risk factor it may be the source for further seeding of ova. Mebendazol therapy was instituted, which will be continued in the future. The patient will remain under observation. PMID:8614666

    Congenital pathologies are those existing at or dating from birth. Occurrence of congenital cystic lesions in the oral cavity is uncommon in neonates. Eruption cyst (EC) is listed among these unusual lesions. It occurs within the mucosa overlying teeth that are about to erupt and, according to the current World Health Organization (WHO) classification of epithelial cysts of the jaws, EC is a separate entity. This paper presents a case of congenital EC successfully managed by close monitoring of the lesion, without any surgical procedure or tooth extraction. Eruption of the teeth involved, primary central incisors, occurred at the fourth month of age. During this time neither the child nor mother had any complication such as pain on sucking, refusal to feed, airway obstruction, or aspiration of fluids or teeth. PMID:21203711

    An eight-year-old, male Siberian husky cross was referred with a history of an acute onset of pelvic-limb ataxia and paraparesis. Radiography and subsequent myelography of the spine revealed an extradural compression of the spinal cord at the level of the 13th thoracic (T13) to first lumbar (L1) vertebrae. Hemilaminectomy resulted in the successful removal of an extradural cystic lesion. The morphological diagnosis based on histopathology was a synovial cyst with chondromatosis. There were no postoperative complications, and the dog's condition improved markedly. At two years postoperatively, the animal remains normal on both physical and neurological examination. To the authors' knowledge, this article is the first report of an intraspinal synovial cyst in a dog. PMID:10825095

    18 patients with 18 hydatid cyst of kidney, underwent surgical intervention from 1982 to 1994. There were 6 men in the series and 12 women who ranged in age from 7 to 65 years (mean 38 years). Flank pain was the chief complaint (55%). Abdominal mass was detected on physical examination in 38% of cases. Ultrasonographic examination, performed in all cases, made a correct diagnosis in 13 patients (72%). Excretory urogram (IVP), performed in 9 patients, showed signs of benign tumor process. All patients were operated on: the procedures performed included 12 resection of "protruding dome", 1 total nephrectomy, 3 partial pericystectomy, 2 total pericystectomy, 1 total nephrectomy. In postoperative course, there was one death (5.5%) and morbidity was 11%. We conclude that hydatid cyst of kidney still rare but possible in endemic areas; its treatment, usually surgical, still difficult because it should avoid recurrence of hydatic disease without sacrifice of the kidney.

    Congenital cysts of the gallbladder are extremely rare, hence only a few ciliated foregut cysts of gallbladder have been reported. We report a case of a 20-year-old woman presenting with mild right upper quadrant abdominal discomfort, with normal levels of serum bilirubin and liver function tests. Abdominal ultrasonography revealed a well-defined cystic mass measured about 2 cm attached to the neck of gallbladder, with internal echogenic debris suggesting a complicated cyst, such as a hemorrhagic cyst. Abdominal computed tomography and magnetic resonance cholangiopancreatography revealed similar findings. Laparoscopic cholecystectomy showed a slightly distended gallbladder. The size of cyst on the neck was 1.6×1.2 cm, and it contained mucosa lined by ciliated pseudostratified columnar epithelium and underlying smooth muscle layers. Histopathology identified a ciliated foregut cyst of gallbladder. PMID:26809633

    We report a rare case of bronchogenic cyst associated with congenital complete absence of the pericardium. A 17-year-old male was admitted to the hospital for surgical resection of a growing cystic lesion located in the middle mediastinum. The patient was asymptomatic and no significant findings were found on physical examination. Resection of the mediastinal cyst was performed by video-assisted thoracoscopic surgery. The complete absence of the pericardium was immediately observed along with a cystic tumor arising from the mediastinum. After the resection of the cyst, no additional procedure to reconstruct the absence of the left pericardium was performed. Pathological diagnosis was a bronchogenic cyst. Congenital absence of the pericardium may be associated with the bronchogenic cyst and complete absence of the pericardium requires no additional surgical reconstruction, if remaining space in the pleural cavity is small enough to avoid cardiac disposition after surgical resection of the cyst.

    The mechanism driving accumulation of large numbers of apoptotic and necrotic neutrophils in inflamed lateral neck cysts (LNC), in the absence of infection, remains obscure. The cellular content of cysts obtained from 17 patients was co-cultured with human macrophages. Phagocytosis levels of cyst-derived neutrophils were determined and compared to the uptake of spontaneously apoptotic neutrophils. Simultaneously, the expression of cytokines in macrophages exposed to cyst contents was measured. In comparison to spontaneously apoptotic neutrophils, the phagocytosis of LNC-derived neutrophils by macrophages was inefficient. An inverse correlation between neutrophil content in LNC and their uptake was observed. Macrophages co-cultured with cyst contents responded with variable expression of IL-6, TNF-? and IL-10. The hindered clearance of apoptotic neutrophils in LNC may lead to secondary necrosis of these cells and stimulation of the inflammatory reaction. Together with local production of anti-inflammatory cytokines, this may fuel chronic inflammation in the cysts. PMID:21755330

    Primary splenic cyst is a relatively rare disease, and the majority of cases are classified as epithelial cysts. Three cases with nonparasitic splenic cysts are presented: two epithelial and one pseudocyst. All cases had an atypical symptomatology, consisted mainly of fullness in the left upper abdomen and a palpable mass. Preoperative diagnosis was established with ultrasonography and computerized tomography. Two cases with large cysts located in the splenic hilum were treated with open complete splenectomy. The most recent case, a pseudocyst, was managed laparoscopically with partial cystectomy. All cases did not have any problems or recurrence during follow-up. Laparoscopic partial cystectomy is an acceptable procedure for the treatment of splenic cysts, because it cures the disease preserving the splenic tissue. Complete splenectomy is reserved for cases in which cyst excision cannot be done otherwise. PMID:16425403

    Gastrointestinal duplication cysts are rare congenital anomalies that can be seen in anywhere of the gastrointestinal system from the mouth to the anus. These are prenatally diagnosed through antenatal ultrasonography. However, attention must be paid since these formations might be confused with ovarian or mesenteric cysts. Our patient, who had been diagnosed with ovarian cyst on the ultrasonography performed in another center and with mesenteric cyst based on the abdominal MRI carried out at fifth month of life, presented to our clinic with the only complaint of constipation at 9th month of life. The diagnosis was set through double wall appearance of duplication cyst on the abdominal ultrasonography. The patient's cyst was resected. PMID:24302931

    Arachnoid cysts are benign developmental collections of cerebrospinal fluid (CSF). They constitute approximately 1% of intracranial masses. The cerebellopontine angle (CPA) arachnoid cysts are rare and often asymptomatic. The onset of symptoms and signs is usually due to the compression of the brain, cranial nerves and obstruction of CSF circulation. The major clinical symptoms for CPA arachnoid cysts were reported as headache, ataxia and 8th cranial nerve palsy. We report a patient with a CPA arachnoid cyst. He presented with cranial nerve palsies and mirror movements found in upper extremities. We postulated that CPA arachnoid cyst compressing the brain stem and the pyramidal decussation may lead to mirror movements. We conclude that mirror movements can be associated with CPA arachnoid cyst.

    Purpose: This paper presents a modification of the known method for percutaneous treatment of hydatid cyst, the PAIR technique. It aimed to achieve safe aspiration of large symptomatic cysts and cysts with a danger of impending rupture. Methods: We designed a coaxial catheter system to achieve concomitant evacuation of cyst contents while infusing scolicidal agent. Hypertonic saline is used to wash out cyst contents and to kill protoscolices. This was followed by injection of a sclerosant (ethyl alcohol 95%) into the residual cyst cavity to prevent formation of a cyst collection after the procedure. Seventeen cysts in 14 patients were successfully aspirated. Follow-up plain radiographs, ultrasonography and CT were performed weekly in the first 4 weeks and then at 3, 6 and 12 months for all patients. Seven patients (9 drained cysts) were followed up for 2 years and 1 patient for 3 years. Results: All cysts were successfully aspirated. The following morphologic changes were noticed: a gradual decrease in cyst size (17 cysts, 100%), thickening and irregularity of the cyst wall due to separation of endocyst from pericyst (7 cysts, 41%), development of a heterogeneous appearance of the cyst components (8 cysts, 47%) and development of pseudotumor (2 cysts, 12%). None of the treated cysts disappeared completely. No significant procedure-related complications were encountered. Conclusion: This modified PAIR technique is a reliable method for percutaneous treatment of risky and symptomatic hydatid cysts.

    Objectives: The purpose of this study was to determine the clinical and demographic characteristics of oral non-odontogenic cysts (ONOC) in a Brazilian population over a 53-year period and to compare this data with the literature. Study Design: A total of 20.391 biopsies records were evaluated, from April/1959 to August/2012. Cases of oral developmental cysts were selected. Data regarding age, gender, time of evolution, and anatomic site of all cases were collected. The data were analyzed by descriptive statistics. Results: Among 20.391 oral biopsies, 71 (0.35%) met the criteria of ONOC. Females accounted for 50.70% of all cases. The mean age observed was 38.14 years (range: 5-88 years). Nasopalatine duct cysts, oral lymphoepithelial cysts and epidermoid cysts were the most common ONOC, accounting for 63 cases (88.73%). Nasopalatine duct cysts occurred in 31 cases (43.66%), followed by 22 patients with oral lymphoepithelial cysts (30.99%) and 10 cases of epidermoid cysts (14.08%). Nasopalatine duct cysts revealed predominance among males (58.06). Oral lymphoepithelial cysts were more commonly observed in tongue (50%). Epidermoid cysts were most frequently found in the buccal mucosa (40.00%). Conclusions: The differential diagnosis of ONOC is based on the clinical, radiological, and histological findings. It is difficult to establish an epidemiological profile of ONOCs, considering the low frequency of these lesions and the divergences in the demographic and clinical presentation data among different populations. Key words:Diagnosis, epidemiology, jaw cysts, mouth. PMID:24316702

    Pediatric neck masses represent a variety of differential diagnoses. A common pathology in pediatric cystic neck tumors include ranulas, mucus retention cysts due to salivary gland obstruction. Epidermoid cysts are lesions infrequently encountered in the pediatric population and may appear similarly to ranulas on computed tomography imaging. MRI more easily differentiates these masses, and should therefore be the preferred imaging modality. Due to their distinct intraoperative management, ranulas and epidermoid cysts should be distinguished preoperatively through proper workup. PMID:26810284

    Endodontic diagnosis is challenging and depends on the organisation of information from the patient history, clinical examination and analysis of the pulp, radiographic and histopathological assessment. A 35-year-old man was endodontically treated for radiolucency in relation to the roots of maxillary central incisors as it was a provisionally diagnosed case of radicular cyst. Since the palatal swelling persisted, the lesion was re-evaluated using relevant diagnostic aids and a diagnosis of nasopalatine duct cyst (NPDC) was made, which was missed during the initial assessment. An erroneous interpretation of cystic radiolucency in relation to maxillary central incisors can often lead to inappropriate treatment planning. This case highlights the relevant aspects in the diagnosis of NPDC when it is mistaken for a radicular cyst and emphasises the need for thorough clinical examination and relevant investigations for periapical radiolucencies of questionable origin before initiating endodontic therapy.

    Atrophic maxilla rehabilitation has been the subject of several studies for decades; despite this, there are still many different therapeutic choices for the best way to treat maxillary resorption in order to enable implant placement and integration. These possibilities include the optimal use of remaining bone structures, such as the pterygoid processes or zygomatic arch, which involves using zygomaticus and pterygoid implants in combination with standard implants placed in the residual bone; alternatively, regenerative techniques, alveolar bone expansion/distraction or bone grafting techniques may be used. Severe maxillary atrophy has a multifactorial aetiology; the most important factors being long evolution edentulism, hyperpneumatization of the maxillary sinus, post-traumatic deficit, bone loss after surgery (tumours, cysts) and periodontal problems or infection. In this report, we present a clinical case of onlay block reconstruction in an atrophic maxilla with harvested cranial calvarium bone grafts for successful future implant-supported oral rehabilitation.

    A 45-year-old woman was hospitalized with complaint of upper right abdominal pain. By serial examination, it was difficult to distinguish renal cyst from renal cancer. But, because of the frequency of the attacks of upper abdominal pain, nephrectomy was undertaken. The tumor measured 5 X 5 X 3 cm, was distinct from normal renal tissue, and consisted of a small cyst. Histologically, we diagnosed a multilocular renal cyst, and its lining cells showed small atypia and adenomatous proliferation. We concluded that this multilocular renal cyst showed neoplastic features. PMID:4032766

    Parathyroid cysts constitute 0.08–3.41% of all parathyroid masses. Intrathyroidal parathyroid cysts, however, are rare conditions with only a few cases being reported. Most of the parathyroid cysts are found to be nonfunctional and functional cysts are generally thought to be due to cystic degeneration of parathyroid adenomas. A cystic, smooth contoured lesion of 24 × 19 × 16?mm was observed in left thyroid lobe of a 76-year-old woman during ultrasonography which was performed as routine workup for primary hyperparathyroidism. It was defined as a cystic thyroid nodule at first. Tc99m sestamibi scintigraphy was performed to see any parathyroid lesions, but no radioactive uptake was observed. Intact parathormone (iPTH) level was found to be >600?pg/mL in cyst aspiration fluid. Left lobectomy was performed, with a diagnosis of primary hyperparathyroidism due to functional parathyroid cyst. Serum iPTH level was decreased >50% postoperatively and histopathological evaluation was consistent with an encapsulated parathyroid adenoma with a cystic center. Parathyroid cysts are among rare causes of primary hyperparathyroidism. Diagnosis is made by markedly increased iPTH level in cyst fluid and observation of parathyroid epithelium lining the cyst wall. PMID:25610671

    Surgery of hydatid cysts is often complicated with intrabiliary rupture (IBR), which if not recognized may lead to biliary fistula with rather high rates of morbidity and mortality. We report our experience with the application of radiofrequency (RF) ablation for the treatment of an operated hepatic echinococcal cyst which was complicated with biliocystic communication and cysteocutaneous fistula with bile leakage. RF ablation was performed under CT guidance into the remaining cyst through the cutaneous fistula. Since ablation of the cyst and the fistula the patient has been asymptomatic.

    An oral foregut cyst is a rare congenital choristoma lined by the respiratory and/or gastrointestinal epithelium. The exact etiology has not been fully identified, but it is thought to arise from misplaced primitive foregut. This lesion develops asymptomatically but sometimes causes difficulty in swallowing and pronunciation depending on its size. Thus, the first choice of treatment is surgical excision. Surgeons associated with head and neck pathology should include the oral foregut cyst in the differential diagnosis for ranula, dermoid cyst, thyroglossal duct cyst and lymphangioma in cases of pediatric head and neck lesions.

    Hydatid cyst is a parasitic cyst caused by the tapeworm Echinococcus that occurs primarily in sheep grazing areas worldwide. It is a chronic disease, and the cysts can be localized in unusual anatomical and geographic locations. It is known to affect the head and neck region. Patients must undergo a thorough systemic investigation as 20-30% show multiorgan involvement. We report a case of hydatid cyst occurring in the buccal mucosa of a 45- year -old male presenting as a small asymptomatic lump and emphasize on its rarity and diagnostic issues. PMID:26392735

    Cystic abdominal lesions are extremely common in adolescent girls and are now diagnosed more frequently due to the availability of better imaging modalities. Presentations as huge cysts have become rare as most of them are diagnosed and treated early. Adolescent girls presenting with huge benign abdominal cysts is not uncommon, most of them due to serious cystadenomas of the ovary, but large follicular cysts are rare. We present a 13-year-old girl who presented with a large abdominal mass which was subsequently diagnosed as juvenile follicular cyst of the ovary. PMID:25177606

    Tardigrades are microscopic metazoans that withstand environmental extremes by entering dormant states, such as cryptobiosis (latent life). In addition, they may also form cysts. Here, we present the first report of cyst formation in a marine heterotardigrade, i.e., Echiniscoides sigismundi, which constitutes a cryptic species complex present worldwide in tidal zones. The cysts were initially discovered during experimental series constructed to investigate osmotic stress tolerance. The animals, which eventually formed cysts, showed signs of an imminent molt at the beginning of experimentation. We use the term "cyst" for stages, where a total of three or more cuticles have been synthesized. Our observations show that encystment in E. sigismundi involves synthesizing of at least two new cuticle layers. Legs with discharged claws are present in connection with the first outer cuticle, as well as the second cuticular layer. In the most developed cyst, a third cuticle lacking claws seems to surround the animal, which is delineated by a fourth cuticle. Many features are shared with the well-studied cysts of eutardigrades. The cysts of E. sigismundi, however, lack pigmentation and have an extra set of claws, and the animal inside retains buccopharyngeal sclerified parts, until discharging the third cuticle. The finding of cysts in a marine heterotardigrade is novel and confirms that encystment also occurs within this major evolutionary lineage.

    This paper is a retrospective study of the first 51 cases of liver hydatid cysts, which underwent a conservative treatment between April 1996-December 2000. There were 28 females and 23 males with a mean age of 40.1 years (7-65), which had 63 liver hydatid cysts. In the right liver lobe were located 46 cysts, in the left liver lobe were located 7 cysts and in 10 cases cysts were located in both liver lobes. In 4 cases a pulmonary hydatidosis was associated. Abdominal ultrasound and CT scan were routinely performed and the cysts were classified in type I and II after Gharbi's classification. All of these 63 cysts were treated by ultrasound guided fine-needle percutaneous puncture with aspiration and instillation of sterile alcohol 95 degrees. Pre and postoperative the patients were treated with mebendazol or albendazol. They were followed-up by ultrasound and CT scan examination in the second day postoperative and monthly. No new cysts were noted during an average follow-up of 14.7 months and maximal cyst diameter decreased with minimum 72%. Two episodes of reversible anaphylaxis were encountered. The mean hospital stay was 3.3 days. In this paper the indications for conservative treatment and preliminary results of this method are discussed. PMID:12731228

    PURPOSE Pineal cysts are common incidental findings during magnetic resonance imaging (MRI) examinations. The etiology of pineal cyst development is still unclear. We aimed to determine whether there is an association between periventricular leukomalacia and pineal cyst prevalence. METHODS Clinical and MRI data of 201 patients with periventricular leukomalacia (110 female, 91 male; mean age, 6 years; range, 2–18 years) and 687 control patients (355 female, 332 male; mean age, 6 years¸ range, 2–18 years) who did not have any evidence of periventricular leukomalacia were independently evaluated by two radiologists for presence or absence of pineal cyst. RESULTS Pineal cysts were detected in 32.3% of the study group (65/201) and 8.4% of the control group (58/687) (P < 0.001). Patients with periventricular leukomalacia were more likely to have a pineal cyst. In terms of pineal cyst detection on MRI, interobserver reliability was high between the two radiologists. CONCLUSION The prevalence of pineal cysts is higher in patients with periventricular leukomalacia. We suggest that an ischemic process may have a role in the etiopathogenesis of pineal cyst development. PMID:25858521
