    Introduction: Simple bone cyst or unicameral bone cyst (UBC) are benign cystic lesions commonly found in femur and humerus. However hand is a very rare site of occurrence. Treatment described for UBC of hand commonly involves curettage and bone grafting. Case Report: A 7 year old right hand dominant girl presented to us with chief complaints of pain and swelling in right 4th metacarpal since 2 month. On imaging, plain radiographs of right hand showed expansile lytic lesion on Metaphyseal-diaphyseal region of 4th metacarpal with pathological fracture. MRI showed cystic lesions with internal loculations and fluid-fluid levels (Fig 2). There was minimal soft tissue extension. We performed aspiration which showed serosanguinous fluid with haemorrhagic tinge. With the diagnosis of unicameral bone cyst in mind we performed and closed intramedullary nail with k wire. The cyst healed up completely within 2 months. There was no recurrence at 18 month follow up. Conclusion: In conclusion simple bone cyst is very rare in metacarpal bone. However it should be considered as important differential since it warrants simple treatment and extensive procedures should be avoided. PMID:27298987

    This study was performed between 2007-2012 and encompasses 94 patients. The patients were divided in two groups. The first group included the patients who have benefited from surgical treatment (42 cases) and the second one included patients who benefited from conservative treatment. Out of the total number of cases, 63 cases showed an intact simple bone cyst that was most of the time an accidental discovery. 31 patients presented with fracture sustained on a simple bone cyst. There were 63 boys and 31 girls. Their mean age was 9.9 +/- 2.34 years. Single injection was performed for 49 patients; the rest had double or triple injections. The mean follow-up was 34.5 +/- 6.6 months. The procedure succeeded in obtaining healing in 77 cysts (82%). Cyst index of more than five and cortical index of less than 1 mm were significantly prone to pathological fractures and had significant poor results after treatment. Our results suggested that an autogenous bone marrow injection is a safe and effective treatment method for simple bone cysts, when compared with the surgical management, but sometimes-repeated injections are necessary. Cyst index and cortical width are good indicators for treatment outcome. PMID:23346253

    Simple and aneurysmal bone cysts are benign lytic bone lesions, usually encountered in children and adolescents. Simple bone cyst is a cystic, fluid-filled lesion, which may be unicameral (UBC) or partially separated. UBC can involve all bones, but usually the long bone metaphysis and otherwise primarily the proximal humerus and proximal femur. The classic aneurysmal bone cyst (ABC) is an expansive and hemorrhagic tumor, usually showing characteristic translocation. About 30% of ABCs are secondary, without translocation; they occur in reaction to another, usually benign, bone lesion. ABCs are metaphyseal, excentric, bulging, fluid-filled and multicameral, and may develop in all bones of the skeleton. On MRI, the fluid level is evocative. It is mandatory to distinguish ABC from UBC, as prognosis and treatment are different. UBCs resolve spontaneously between adolescence and adulthood; the main concern is the risk of pathologic fracture. Treatment in non-threatening forms consists in intracystic injection of methylprednisolone. When there is a risk of fracture, especially of the femoral neck, surgery with curettage, filling with bone substitute or graft and osteosynthesis may be required. ABCs are potentially more aggressive, with a risk of bone destruction. Diagnosis must systematically be confirmed by biopsy, identifying soft-tissue parts, as telangiectatic sarcoma can mimic ABC. Intra-lesional sclerotherapy with alcohol is an effective treatment. In spinal ABC and in aggressive lesions with a risk of fracture, surgical treatment should be preferred, possibly after preoperative embolization. The risk of malignant transformation is very low, except in case of radiation therapy.

    Aneurysmal bone cysts associated with tubular bones of the hand occur rarely and require particular diagnostic and therapeutic management techniques. While optimal treatment has not been established, accepted treatments range from aggressive radical treatment, including en bloc resection and excision diaphysectomy with strut bone grafting, to relatively simple techniques, such as thorough curettage followed by bone graft. Aggressive treatment approaches may be optimal for the cases with articular surface involvement, full-bone invasion of the phalanx or metacarpal, or more than 1 recurrence. We report a monocentric case of aneurysmal bone cysts involving metacarpal bone in a child who achieved favorable outcome with curettage and morselized cancellous bone grafts. PMID:25750953

    Simple cysts are rare in the urinary bladder and can pose a diagnostic dilemma to both the urologist and the histopathologist. No case study was found in the database of Elsevier Science Direct, Spring-Link, or PubMed. We present two cases of subserous cyst in the bladder and discuss the diagnosis and treatment of the condition. The cystic lesion at bladder dome was detected by radiologic examination and confirmed by cystoscopy. In case 1, transurethral resection was first performed which was followed by partial cystectomy; In case 2, the cyst was removed with the urachus using laparoscopic surgery. The patients recovered uneventfully and the histopathology showed cysts in subserous layer of urinary bladder. The bladder cyst should be distinguished from urachal tumor, and laparoscopic partial cystectomy is the preferred operative procedure.

    A 90-year-old woman presented with headache and diplopia, and a mass in the nasal cavity and paranasal sinuses was found on CT scan. The patient underwent examination under anaesthesia showing a mass arising from the ethmoid, apparently from the nasal septum. Biopsies taken showed an aneurysmal bone cyst. The patient opted against surgery and has been managed conservatively. A second CT scan 4 years later showed significant increase in size. PMID:24706701

    Objective Various organs are known to be affected by the comorbidities of acromegaly. However, the involvement of renal structural comorbidities, such as cysts, has so far remained largely unknown. In this single-center study, we aimed to determine the prevalence and factors associated with simple renal cysts in Japanese patients with acromegaly. Methods A total of 71 consecutive patients with acromegaly were analyzed, who all underwent abdominal ultrasonography at diagnosis between 1986 and 2012 at Kobe University Hospital. Results Of these 71 patients, 23 (32.4%) exhibited simple renal cysts. Acromegalic patients with renal cysts tended to be significantly older, had a higher prevalence of smoking- and higher nadir growth hormone (GH) levels during the oral glucose tolerance test (OGTT) than did those without renal cysts. A multivariate logistic regression analysis showed age, smoking, and nadir GH to be independent factors associated with renal cysts. Interestingly, the number of renal cysts positively correlated with both the basal GH levels and nadir GH levels during OGTT (r=0.66, p<0.05 and r=0.70, p<0.05, respectively). In addition, the mean diameter of renal cysts positively correlated with the systolic blood pressure (r=0.84, p<0.005). Conclusion This is the first report to show the prevalence of simple renal cysts in patients with acromegaly. Elevated nadir GH levels during OGTT were found to be associated with an increased risk of simple renal cysts. Therefore, an excessive secretion of GH may be related to the development of renal cysts. PMID:27374666

    This article documents the outcome of treatment of intraosseous ganglia and simple bone cysts of the carpal bones by curettage and injectable calcium phosphate bone cement (CPC) grafting. The patients consisted of five men and three women. One had a cystic lesion in the scaphoid, one in the hamate, and five in the lunate. Curettage of the lesions was performed, and CPC was injected into the cavity. Five patients were diagnosed with a ganglion and three with a simple bone cyst. Among the five patients with wrist pain, the pain disappeared completely in four. Radiographs showed apparent partial absorption of CPC in four patients and no absorption in other four. There were no recurrence of tumours and no other complications were encountered. We conclude that calcium phosphate bone cement is a useful material for repairing bone defect after curettage of an intraosseous ganglion or bone cyst of a carpal bone.

    Aneurysmal bone cysts (ABC) are rare, benign, expansile lesions of bone often found in the metaphyses of long bones in pediatric and young adult population. Multiple fluid levels are typically seen on imaging with magnetic resonance imaging (MRI) or computed tomography (CT). We describe a case of a primary ABC in the fibula of a 34-year-old man diagnosed on ultrasound with a mobile fluid level demonstrated sonographically. PMID:24587935

    Aneurysmal bone cyst is a rare, rapidly growing, and destructive benign bone tumor that even more rarely involves the bones of the hand. Various treatment options for aneurysmal bone cyst have been reported in the literature, but controversy exists regarding optimal treatment. Due to its rarity in the hand, no evidence-based treatment regimen has been established. A 21-year-old man presented with a history of pain and local swelling over his fifth metacarpal of 5 months' duration. Physical and radiographic examination of the hand was consistent with aneurysmal bone cyst. After biopsy, pathologic examination confirmed the diagnosis of aneurysmal bone cyst. En-block resection of the tumor and autologous bicortical strut graft fixation with Kirschner wires was performed. The hand was immobilized in a short arm cast for 3 weeks after the patient received 3 weeks of physiotherapy. Kirschner wires were removed 6 weeks postoperatively. Excellent clinical and functional results were obtained with no recurrence after 3 years of follow-up with en-block resection and reconstruction with iliac crest graft. Radiographic examination demonstrated the osseous integration of the graft with no signs of recurrence. Although treatment should be planned individually according to lesion site and size and to patient age, we suggest en-block resection to prevent recurrence and secondary surgical interventions particularly in cases with no articular involvement.

    Pericardial cysts are rare and generally benign intrathoracic lesions, most frequently located in the cardiophrenic angles, but other locations have been described. We present a case of a pericardial cyst in a previously undescribed site. Our patient presented with a cyst in the interventricular septum which was discovered as an incidental finding. After surgical excision of the cyst, it was described pathologically as a simple mesothelial pericardial cyst. The explanation of this rare condition is uncertain, but some hypotheses can be outlined.

    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.

    Chondroblastoma is an uncommon benign bone tumour, involvement of epiphysis of long bones is typical. Chondroblastoma of the calcaneum is uncommon and its association with secondary aneurysmal bone cyst is even rarer. Only two cases of calcaneal chondroblastoma associated with secondary aneurysmal bone cyst have been reported till date. A 22-year-old male presented to the department of orthopaedics with complains of pain and swelling in the left heel since the last 10 months. On clinico-radiological grounds differentials considered were giant cell tumour of bone and aneurysmal bone cyst. In view of the histopathological findings of bone curettage and results of special stain and immunohistochemical marker, final diagnosis of chondroblastoma with secondary aneurysmal bone cyst, left calcaneum was rendered. Although rare, chondroblastoma should always be considered in osteolytic lesions of calcaneum. The identification of secondary aneurysmal bone cyst component is important as it has higher chances of recurrence than usual chondroblastoma.

    Cystic spinal lesions with characteristic patterns, such as the presence of haematic fluid-fluid levels (H-FFL), have been associated with many tumoral lineages, more frequently with aneurysmal bone cyst (ABC) and exceptionally with metastasis. We present the case of a 60-year-old man with the finding of a sacral cystic bone lesion with H-FFL, with initial suspicion of ABC and confirmed diagnosis of metastasis. The case presented is, to our knowledge, the second case published of spinal cystic bone metastasis with H-FFL pattern with unknown primary tumour at the time of diagnosis and the only one that received resective surgical treatment, achieving pulmonary and metastatic disease control with good quality of life after 1 year of follow up.

    Chondroblastoma of the patella is rare. Aneurysmal bone cysts, which develop from a prior lesion such as a chondroblastoma, are seldom seen in the patella. The authors report a case of a 36-year-old man who presented with 2 years of right knee pain without calor, erythema, pain on palpation, or abnormal range of motion. Radiological studies suggested aneurysmal bone cyst. The lesion was excised with curettage and the residual cavity filled with autogenous bone graft. Histopathology revealed chondroblastoma associated with a secondary aneurysmal bone cyst. In the follow-up period, the patient demonstrated normal joint activities with no pain. Normal configuration of the patella and bone union were shown on plain radiographs. The authors present a review of the literature of all cases of patellar chondroblastoma with aneurysmal bone cyst. This case is the 14th report of aneurysmal bone cyst arising in a chondroblastoma of the patella. According to the literature, computed tomography and magnetic resonance imaging are useful in the study of these lesions. The pathologic diagnosis is based on the presence of chondroblastoma and aneurysmal bone cyst. Treatment of this lesion includes patellectomy, curettage alone, and curettage with bone grafting. Despite the risk of recurrence of this lesion in the patella, the authors first recommend curettage followed by filling the cavity with bone graft. To protect the anterior tension of the patella intraoperatively, the bone window should be made at the medial edge of the patella to perform the curettage and bone grafting.

    Splenic cysts are rare clinic entities. Non-parasitic cysts are the most frequent cystic lesions of the spleen. In the last decade acknowledgment of the importance of the spleen function, along with development of imaging methods and surgery technics, allowed a conservative approach to be increasingly considered as the best approach in splenic cysts treatment. We present the case of a 34-year-old woman with an asymptomatic simple splenic cyst in the upper pole incidentally diagnosed in a thoracic CT. A laparoscopic upper pole splenectomy was performed on the patient, with no complications. Despite the rareness of this procedure and the fact that it was used in a simple splenic cyst, this article emphasises the idea that this approach is safe, reproducible and advantageous for the patient.

    Simple cysts of the testis are an uncommon lesion found in adults as well as infants. Only a few histological and immunohistochemical studies for this lesion have been reported because the lesion have rarely undergone surgical excision or histological confirmation. Herein is reported an autopsy case of simple cysts of the right testis found incidentally in an 84-year-old man who died of hepatocellular carcinoma. The cysts were multilocular, 12 x 8 mm in size, separated from the tunica albuginea and filled with transparent and colorless serous fluid. Histology and immunohistochemistry showed that the cystic lesion had flattened or cuboidal single-layered lining cells that were positive for cytokeratin AE1/AE3, calretinin, D2-40, HBME-1, mesothelin and thrombomodulin, indicating its mesothelial origin. To the authors' knowledge this is the first English-language report describing the origin of simple cysts of the testis. Although the exact pathogenesis of simple cysts of the testis is as yet unknown and there seems to be more than one etiology, at least in the present case the cysts were confirmed to correspond to mesothelial inclusions.

    2000-12-01

    Laparoscopic excision and marsupialization of symptomatic of recurrent simple renal cysts is an alternative to open or percutaneous surgery. Such surgery may also be useful for pain relief in patients with autosomal dominant polycystic kidney disease (ADPKD). An occlusion balloon catheter is placed in the renal pelvis at the start of the procedure. Cysts are punctured, and the outer wall of the larger cysts is excised with care not to incise the renal parenchyma. In patients with ADPKD, it is important to mobilize the kidney completely, particularly the upper pole, to treat every visible cyst. A laparoscopic ultrasound probe is used to guide the unroofing of any large cysts within 5 to 10 mm of the renal surface. At the end of the procedure, the integrity of the collecting system is confirmed. Strict criteria must be used in selecting patients with simple cysts for laparoscopic marsupialization to minimize the incidence of unsuspected malignancy, and the cyst wall should be examined by frozen and permanent section. Long-term follow-up is needed to evaluate the effect of laparoscopic decompression in ADPKD.

    Laparoscopic dissection of common renal cysts was made in 27 patients who complained of low back pains and hypertension. The diagnosis and indications for operation rested on ultrasonic investigation and dynamic nephroscintigraphy. All the surgical interventions were performed under endotracheal anesthesia after creation of pneumoperitoneum with the use of three trochars. The procedure comprised maximal dissection of the free cystic wall, electrocoagulation of the residual part's margins and retroperitoneal drainage. Postoperative period was uneventful in 92.6% of the cases. Control examination 3 and 6 months after the operation indicated good results: pain relief, stabilization of arterial pressure and improvement of renal function.

    Aneurismal bone cyst is a rare tumour. The authors report an exceptional case in its clavicle localization. They review the diagnosis circumstances and treatment modalities of this pathology. The occurrence of the cyst is linked to vascular homodynamic disturbance and its discovery in a post-traumatic context has been assessed by the histology exam. Although numerous therapeutic trials, radical removal versus conservatory methods avoid relapse. Finally, resection of the clavicle leading to few functional consequences should be recommended for the cure of evoluted aneurismal bone cyst.

    Aneurysmal bone cyst (ABC) is an expanding osteolytic lesion. ABC represents 1% of all primary benign bone tumors, whereby 4-12% occur in the pelvis. The etiology of this disease remains vague. Aneurysmal bone cyst can exist either as primary bone lesion (70%) or as secondary lesion arising from another bone disorder (30%). Moreover, pelvic ABCs are characterized by their large size and high vascularity. We present a rare pediatric case with ABC involving the ischial region. A 5-year-old girl presented with left pelvic pain and limping for the past 6 months. Initial imaging showed an expansile lesion in the left ischium, and computed tomography guided biopsy showed giant cells in histopathology study with no evidence of metastasis. The patient underwent intraoperative frozen section followed by extensive intra-lesional bone excision. Bone curettage was pursued along with bone grafting. The case was successfully managed without postoperative complications after the 6-month follow-up period. PMID:27381543

    Aneurysmal bone cyst are commonly seen in long bone and vertebrae. There are rare in skull bones especially in the temporal bone and zygomatic arch. We report one case in a young male of 15 years old. The main symptom was swelling of the temporo mandibular region. Clinical, radiological and therapeutic aspects of the disease are discussed with regards to the literature. The diagnosis is based on good imaging and histopathological analysis. Surgical removal is the main treatment.

    Aneurysmal bone cysts (ABCs) are benign, non-neoplastic, expansile, vascular, locally destructive lesions. The lesion may arise de novo (65%) or secondarily (35%) in pre-existing benign or malignant lesions (giant cell tumor, osteoblastoma, chondroblastoma, angioma, and others). The calcaneus is a rare localization for ABC, comprising only 1.6% of the cases. In this paper, we present a case of a female patient with a 3-month history of heel pain that got worse and was accompanied by swelling and difficulty in walking. The magnetic resonance images of the postero-lateral calcaneus showed a contrast-enhanced cystic lesion located in the medullary cavity; exophytic portion of the tumor extended into the soft tissue causing distinctive cortical thinning. Heterogeneous hyperintense septae formations and blood level components were also detected. After correlation with pathology results, the lesion was diagnosed as an ABC. Since an ABC of the calcaneus is a rarely seen phenomenon, we present the radiologic findings in this case and a review of the literature. PMID:25396076

    1997-03-01

    A rare, large pediatric aneurysmal bone cyst with pathologic fracture of the distal tibia of a 4-year-old female was presented. Classic radiographic and magnetic resonance imaging findings have been discussed. In a comprehensive review of the literature, aneurysmal bone cysts are an infrequently reported neoplasm of the foot and ankle bones. Lesions are characteristically seen in patients younger than 20 years of age, but rarely younger than 5 years. The benign cyst has a 2:1 female-to male predilection. In long bones, the lesion is typically metaphyseal in nature. Although the pathogenesis is still unknown, there exists the possibility of two types of aneurysmal bone cysts: a primary type without preexisting lesion and a secondary form associated with some other lesion. The diagnosis of aneurysmal bone cyst can be strongly suspected by correlating the radiographic and magnetic resonance imaging findings. For definitive diagnosis, accurate histologic evaluation is imperative to rule out any confusion or possibility with a malignant tumor. PMID:9086721

    A simple and easy cryosurgical method to treat intraoral mucous cysts is described. Twelve female and six male patients, with mucous cysts on the lower lip and the tip of the tongue, were treated by direct application of liquid nitrogen with a cotton swab. Each lesion was exposed to four or five cycles composed of freezings of 10-30 s and thawings of double the freezing times. No anesthesia was required. All lesions had disappeared completely 2-4 weeks after one or two treatment courses of cryosurgery. In all cases, neither scarring nor recurrence was noted during the 6 months to 5 years of follow-up. PMID:8106810

    Gastric duplications are rare anomalies and usually occur along the greater curvature of the stomach. The authors herein describe an uncommon case of a retroperitoneal gastric duplication, which was not found during previous emergency laparotomy for suspected peritonitis at another institution. On subsequent computed tomography scan, the lesion was misinterpreted as a simple exophytic renal cyst. Laparoscopy was undertaken because of unresolved symptoms, and a retroperitoneal duplication cyst was successfully excised. It was lined with gastric mucosa and islands of pancreatic tissue on pathologic examination.

    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.

    2015-01-01

    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.

    Chondroblastoma is a benign tumor that typically arises in the epiphysis of a long bone. There have been only 2 reported cases of chondroblastoma involving the capitate. This is the first report of chondroblastoma with secondary aneurysmal bone cyst involving the capitate. A 33-year-old man presented with a 3-year history of pain and swelling of the right wrist. Radiography as well as computed tomography showed a radiolucent area and no matrix calcification within the capitate. Magnetic resonance imaging revealed a homogeneous signal that was low on T1-weighted images and high on T2-weighted images and showed only slight enhancement. On the basis of imaging findings, the authors chose excisional biopsy. The bone tumor in the capitate was explored through a dorsal approach by dividing the extensor tendons. After repeated curettages, bone graft substitute using allograft bone was packed into the capitate. Histologically, the authors diagnosed this tumor as a chondroblastoma with a secondary aneurysmal bone cyst. At the final 2-year follow-up, there was evidence of bone union, full range of motion, and recovery and no evidence of recurrence. Although the recurrence of chondroblastoma is occasionally reported, the principal treatment is intralesional curettage and bone graft. High-speed burring, phenol, bone cement, and cryosurgery have been reported to reduce local recurrence. Complete excision of the carpal bone seems to be overtreatment.

    Introduction: Aneurysmal Bone Cyst (ABC) is a benign expansile cystic blood filled reactive lesion of the bone, most common in the first 2 decades of life. Though it can involve any bone in the body but tibia, humerus, femur and posterior elements of spine are most commonly affected. They most commonly involve metaphysis or metaphysio-diaphyseal part of the bone. Primary involvement of epiphysis is rarely reported. Here we present a case of 6 year old male child with an epiphyseal ABC of distal ulna. Its diagnosis, surgical management, clinical outcome with review of literature is discussed. PMID:27299110

    What's known on the subject? and What does the study add? Simple renal cysts are a common entity, which may need observation and follow-up or treatment. The study, for the first time, systematically reviews the indications for follow-up or radiological treatment of simple renal cysts. To review the conservative and radiological management of simple renal cysts a systematic literature review was performed. Simple renal cysts are commonly found in the adult population. Increasing age is highly associated with its incidence. When they remain asymptomatic they require neither treatment nor follow-up. When the shape of the cyst is slightly irregular follow-up is mandatory to exclude malignant progression. Symptomatic cysts require intervention. Ultrasound or computed tomography guidance have been effectively used for cyst puncture. However, simple fluid aspiration is ineffective leading to cyst recurrence. Aspiration should be accompanied with the injection of a sclerosing agent to destroy renal cyst epithelium. Several issues such as the ultimate technique and agent remain to be clarified. High rates of cyst disappearance and long-lasting cyst volume reduction have been reported with the use of various sclerosants. Ethanol in high concentrations and multiple injections is more commonly used with new agents showing similar efficacy and better complication profile. Studies comparing radiological intervention to surgical excision are lacking. Simple renal cysts may not require treatment when asymptomatic. Radiological intervention with the use of sclerosants needs further evaluation and comparison with other treatment methods.

    A case is presented of minimum renal trauma, leading to a retroperitoneal hematoma as a consequence of a simple renal cyst rupture as well as an artery contained therein. The etiopathogenicity of this phenomenon is commented. The different clinical manifestations of renal trauma are highlighted, as well as the suspicion of previous renal pathology when a large renal lesion is found secondary to minimum renal trauma. The approach of the renal pediculum must be the first step in the surgical treatment of renal trauma.

    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.

  13. A simple fibril and lectin model for cyst walls of Entamoeba and perhaps Giardia.

    PubMed

    2011-01-01

    Cyst walls of Entamoeba and Giardia protect them from environmental insults, stomach acids, and intestinal proteases. Each cyst wall contains a sugar homopolymer: chitin in Entamoeba and a unique N-acetylgalactosamine (GalNAc) homopolymer in Giardia. Entamoeba cyst wall proteins include Jacob lectins (carbohydrate-binding proteins) that crosslink chitin, chitinases that degrade chitin, and Jessie lectins that make walls impermeable. Giardia cyst wall proteins are also lectins that bind fibrils of the GalNAc homopolymer. Although many of the details remain to be determined for the cyst wall of Giardia, current data suggest a relatively simple fibril and lectin model for the Entamoeba cyst wall.

    Objective To measure the occurrence and natural history of simple ovarian cysts in a cohort of older women. Study Design Simple cysts were ascertained among a cohort of 15,735 women from the intervention arm of the Prostate, Lung, Colorectal and Ovarian (PLCO) Cancer Screening Trial, through 4 years of transvaginal ultrasound screening. Results Simple cysts were seen in 14% of women the first time their ovaries were visualized. The one-year incidence of new simple cysts was 8%. Among ovaries with one simple cyst at the first screen, 54% retained one simple cyst, and 32% had no cyst one year later. Simple cysts did not increase risk of subsequent invasive ovarian cancer. Conclusions Simple ovarian cysts are fairly common among post-menopausal women, and most appear stable or resolve by the next annual exam. These findings support recent recommendations to follow unilocular simple cysts in post-menopausal women without intervention. PMID:20096820

Although laparoscopic unroofing of a renal cyst is a safe and effective alternative to open surgical techniques, the transperitoneal approach should only be used for simple renal cysts. The retroperitoneal approach for complicated renal cysts may be indicated if preoperative examinations exclude the possibility of malignancy.

    A 12-year-old boy had been known to have a small swelling in the left high vertex for several years. After a trivial head hit to the site of the swelling, the swelling enlarged gradually. A bone window CT scan showed a lesion having bubble-like lytic change in the left parietal bone. Similar changes, but small, were able to be pointed out in a CT scan taken seven years previously. In the following 13 months CT scans eventually revealed sequential increases to 3.5 cm in diameter. Surgical exploratory resection of the mass was performed. Intraoperatively, partial destruction of the outer skull table and a simple cyst with serous yellowish brown colored fluid were identified. There was no finding adherent to the diploic structure. The bone defect after excision was reconstructed by using a titanium plate. The patient was followed up for 2 years after the surgery. Bone window CT showed bony development of normal appearance. Histological examination showed the cyst wall consisted of fibrous connective tissue but there were neither epithelial nor endothelial cells. The histopathological diagnosis of SBC was most likely. SBC is relatively common in long bones, but rarely in flat bones. Only several cases of the SBC of cranial bone have been reported. Although a craniectomy for total excision followed by cranioplasty by resin was common, in cases of children, cyst removal with titanium plate application would be an alterative. SBC increasing in size after head injury is extremely rare, but clinicians may need to be aware of cystic skull bone tumors increasing in size after head injury. PMID:22728540

    Objective Our goal was to document the presentation, location, diagnostic modalities, preoperative embolization status, treatment, histology, complications, and recurrence rates for aneurysmal bone cysts of the mobile spine. Methods We reviewed our institution's database to identify patients diagnosed with aneurysmal bone cysts of the mobile spine (excluding the sacrum) from 1995 through 2006. Of those 17 patients, three were treated elsewhere and 14 underwent surgical treatment at our institution. Of those 14 patients, the nine (mean age at presentation, 17.2 years; range, 5‥32 years) with at least 2 years of follow-up (average, 49.6 months; range, 24‥88 months) formed our study group. For those nine patients, we tabulated the presentation, location, diagnostic modalities, preoperative embolization status, treatment, histology, complications, and recurrence rates. Results Pain was the presenting symptom in all nine patients. The lesion most commonly occurred in the cervical spine (five); two occurred in the lumbar spine, and two occurred in the thoracic spine. Patients underwent resection and combined anterior and posterior spinal arthrodesis (six) or resection and posterior spinal arthrodesis (three). There were four complications: one iliac crest donor site infection, one incidental durotomy, and two neurologic defcits. We noted two recurrences (both within 3 months). Conclusions Aneurysmal bone cysts of the spine can be successfully treated with surgical resection and instrumentation. PMID:23576920

    Abstract Because hydatidosis of the bone (echinococcus infection) is a rare parasitic infection, its diagnosis and treatment poses great difficulties. Radiologic imaging findings are generally helpful to make the diagnosis. But occurrence of disease in atypical places and lack of specific radiological findings may complicate differential diagnosis. Nevertheless, familiarity with imaging findings in patients living at endemic areas provides advantages for diagnosis and treatment. We present a cyst hydatic case in scaphoid bone which has been reported in the literature only once previously. PMID:27124019

    Unicameral bone cysts (UBCs) are benign tumor-like lesions that commonly occur in the diaphyseal or metaphyseal region of the long bones within the first 2 decades of life. Until today, the pathogenesis of UBC has been unclear, but mechanisms such as vascular occlusion or a response to trauma have been supposed. During the past decade, in particular, the genetic aspects of the development of this rare lesion have been discussed. We present the first case of mirror image monozygotic twins with a mirror image UBC of the calcaneus. Our findings reinforce the importance of additional studies to understand the significance of cytogenetic factors in the etiology of UBC.

    Unicameral bone cyst is a common benign bone tumor and most frequent cause of the pathological fracture in children. We have started a prospective study for that treatment of unicameral bone cyst by using freeze dried radiation sterilized bone allograft impregnated with autogenous bone marrow in the department of Orthopaedics, Bangabandhu Sheikh Mujib Medical University (BSMMU) during May 1999 to April 2012. Aim of this study was to see Freeze dried radiation sterilized bone allograft impregnate with autogenous bone marrow a satisfactory graft material in the treatment of unicameral bone cyst as well as factors such as patients age, sex, cyst size and site of lesion influence on cyst healing. A total 35 patients of unicameral bone cyst were operated. In this study out of 35 patients, male were 22(62.86%) and female were 13(37.14).

Common bones sites involvements are proximal end of Humerus 20(57.14%), proximal end of Femur 7(20 %), proximal end of Tibia 3(8.57%), Calcanium 2(5.71%), proximal end of Ulna 1(2.86%), shaft of Radius 1(2.86%) and Phalanx 1(2.86%). Final clinical outcome of unicameral bone cyst treated by thorough curettage of cavity and tightly filled with freeze dried radiation sterilized bone allograft impregnate with autogenous bone marrow in which healed (success rate) 88.57% (31) and recurrence rate is 11.43% (4). P value is <0.001. Follow up period was 6 month to 11 years. From our study it was realized that freeze dried radiation sterilized bone allograft impregnated with autogenous bone marrow is useful graft material for healing of the lesional area as well as restoring structural integrity for the treatment of unicameral bone cyst.

    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 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

    Chondroblastoma is a rare, benign tumor of bone, accounting for about 1% of all bone tumor cases. It tends to affect the epiphyseal ends of long bones, most often in males during the first and second decades of life. It has well-characterized radiographic and histologic features but despite its histologically benign appearance a few cases of metastases have been reported. Local recurrences after curettage and bone grafting occur in 11% to 25% of cases. The features of a patellar chondroblastoma are the same as for other locations. In reviewing the literature we found an unusually high male-to-female ratio. It is interesting that the usual treatment of the patellar chondroblastoma has been patellectomy, whereas curettage and bone grafting has predominated in the other locations. We present a computer tomography and magnetic resonance imaging study of a case of chondroblastoma of the patella associated with an aneurysmal bone cyst. To our knowledge, it is the seventh case reported and the second with computer tomography and magnetic resonance imaging studies. We also review and discuss in detail all the cases of patellar chondroblastoma that we found in the literature.

  6. Lower Limb Reconstruction with Tibia Allograft after Resection of Giant Aneurysmal Bone Cyst

    PubMed Central

    2016-01-01

    Aneurysmal bone cysts (ABCs) are benign, expansible, nonneoplastic lesions of the bone, characterized by channels of blood and spaces separated by fibrous septa, which occur in young patients and, occasionally, with aggressive behavior. Giant ABC is an uncommon pathological lesion and can be challenging because of the destructive effect of the cyst on the bones and the pressure on the nearby structures, especially on weight-bearing bones. In this scenario, en bloc resection is the mainstay treatment and often demands complex reconstructions. This paper reports a difficult case of an unusual giant aneurysmal bone cyst, which required extensive resection and a knee fusion like reconstruction with tibia allograft. PMID:27413565

    Clear cell chondrosarcoma is a rare cartilaginous tumour of low-grade malignancy. Although it has a characteristic histological appearance, its radiological features and clinical presentation often mimic a benign lesion. Herein, we describe the case of a patient with a clear cell chondrosarcoma of the right proximal femur that had an atypical appearance of chronic avascular necrosis on initial plain radiographs, which made preoperative diagnosis a challenge. In addition, the tumour also had extensive areas of aneurysmal bone cyst-like changes, which is not only a rare histologic phenomenon in clear cell chondrosarcoma, but also a confounding factor in the interpretation of the radiologic findings.

    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

    Traumatic bone cyst is an uncommon non-epithelium lined cavity and is seen frequently in young individuals. The lesion occurs more commonly in the mandible, involving the posterior region. It is generally asymptomatic and is diagnosed on routine radiographic examination. The cystic cavity is usually empty and there is scanty material for histological examination. Surgical curettage is usually done and recurrence is rare. A case of traumatic bone cyst occurring in the anterior region of mandible in a young boy is presented. Following surgical intervention, plasma-rich-protein was placed in the cystic cavity. The lesion showed progressive resolution and bone regeneration of the cystic cavity within a short period of time. PMID:24926221

    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.

    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.

    PURPOSE Intraosseous cysts of carpal bones are frequently observed on routine imaging examinations of the wrist. There is controversy regarding the underlying pathogenesis of these cysts. In this study, we aimed to investigate the magnetic resonance imaging (MRI) appearance of intracarpal bone cysts in correlation with histologic analysis, using cadaveric wrists. METHODS Five freshly frozen cadaveric wrist specimens (from three women and two men; mean age at death, 80 years) were studied. Imaging was performed with T1-weighted fast spin-echo, and proton density-weighted fast spin-echo with and without fat-suppression. The existence of cysts was confirmed by comparing MRI and histology findings. Hematoxylin and eosin stain was performed on tissue slices of 3 mm thickness to analyze the structure of cysts and their communication with the joint cavity. RESULTS Ten cysts were observed. In all cases, cysts were eccentrically located either in the subchondral bone or beneath the cortex. On histologic examination, there were regions of fat necrosis without inflammation or increased vascularity, surrounded by fibrous walls. There were no giant cells, cholesterol granules, or a true synovial lining. Mucoid change was rare. Fibrous component of cysts varied from small fibrous septa to well-formed walls. Some cysts communicated with the joint cavity. Two cysts were adjacent to ligamentous attachments. Those cysts with fibrous tissue demonstrated variable hypointensity on T2. CONCLUSION In contrast to previous reports that described a mucoid composition of intracarpal bone cysts with occasional foamy macrophages, our observations support the concept that these lesions reflect a spectrum of fat necrosis and fibrous changes, without inflammation or hypervascularity. These cysts are typically surrounded by fibrous walls without a true synovial lining. PMID:25205027

    Simple liver cysts are common, rarely causing significant morbidity or mortality. Budd-Chiari syndrome (BCS) is caused by obstruction of hepatic venous outflow and is the leading cause of postsinusoidal liver failure. We present a rare case of BCS caused by a simple hepatic cyst. A 16 cm × 16 cm liver cyst was found on computed tomography of a 66-year-old woman presenting with abdominal pain. The cyst had become infected, thus enlarged, exerting mass effect with almost complete compression of the inferior vena cava. Shortly after admission, the patient developed acute liver failure, with deranged clotting and hepatic encephalopathy requiring full organ support on the intensive care unit. Cardiac output studies showed a low cardiac index of 1.4 l/min/m(2). An emergency laparotomy with fenestration of the cyst and drainage of 2l of purulent material led to a full recovery. Intraoperative cystic fluid aspirates later confirmed no evidence of Echinococcus. Histology confirmed a simple cyst. Liver biopsies showed severe, confluent, bridging necrosis, without background parenchymal liver disease. Acute BCS due to rapid compression of all major hepatic veins leading to fulminant hepatic failure is rare. Our case highlights a clinically significant complication of a simple liver cyst of which clinicians should be aware when managing these 'innocent' lesions.

    An aneurysmal bone cyst (ABC) is a rare, non-neoplastic, destructive, hemorrhagic and expansile lesion accounting for 1% of all bone tumors. This type of lesion predominantly affects long bones and vertebrae. ABC of the metatarsal is rare and only a few cases have been reported in the literature to date. The present study reports a rare case of ABC of the third metatarsal occurring in a 27-year-old male patient, who presented with repeated foot swelling that had lasted for ~1 year. Other clinical manifestations included limping, multiple lumps (defined as masses on or below the skin, as detected by imageological diagnosis) and progressively increasing local pain in his right foot. Magnetic resonance imaging of the right metatarsal revealed a segmented, expansile, multiseptated lesion with fluid-fluid levels. An en bloc resection was performed and the defect was replaced with a tricortical iliac autograft. Pathological analysis of the resected tissue suggested ABC. The present study aims to describe a case of ABC of the metatarsal, a condition that often poses a diagnostic challenge, and to underline the importance of radiological and histological examinations for the accuracy of that diagnosis.

    Juvenile bone cysts usually are asymptomatic and may manifest as pathological fractures. Since the new method of flexible intramedullary nailing (" Elastic Stable Intramedullary Nailing" - ESIN or " Embrochage Centro- Médullaire Elastique Stable" - ECMES) has demonstrated superb results in the treatment of non-pathologic fractures of the long bones in childhood, this method is rapidly gaining popularity for the treatment of spontaneous or pathological fractures. Given the self-limiting natural history of juvenile bone cysts with eventual spontaneous healing, our goal is to stabilise the pathological fracture and the biomechanically weakened humerus. We treated 15 patients with 16 pathological fractures (one re-fracture) due to juvenile bone cysts of the proximal humerus. All fractures healed completely without pseudarthrosis. Complications were a secondary fracture in otherwise correctly positioned nails. Five of the 15 implants remain in situ, in 6 cases a repeat osteosynthesis was necessary, in one case the nails had to be changed because of the re-fracture. Ten of the 15 juvenile bone cysts healed over a period of 3 years, the nails were removed and so far there have been no further fractures in this group. In the other 5 cases, the juvenile bone cysts have progressively filled with sclerotic bone, and the nails remain in situ. PMID:12664415

    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.

    Chondroblastoma is a relatively rare benign bone tumor. Approximately 7% of chondroblastomas occur in the calcaneus, and 17% of chondroblastoma associated with cystic lesions. We report a case of a chondroblastoma in the calcaneus with a secondary aneurysmal bone cyst treated successfully by endoscopic curettage without bone grafting. New bone formation is facilitated by minimal damage to the bone and soft tissue. The cosmetic results of this procedure are good. Two years later, the patient is asymptomatic with no radiographic evidence of recurrence. Endoscopic curettage without bone grafting is a promising new treatment for chondroblastoma.

    The treatment of cystic lesions and the extraction of impacted third molars are 2 of the most common procedures in oral and maxillofacial surgery. The surgical treatment of cysts of the jaws can consist of a cystectomy, a cystotomy, or a staged combination of the 2 procedures. The surgical techniques developed for the extraction of impacted third molars are: coronectomy, orthodontic extraction, and surgery using intraoral or extraoral methods. There are various complications related to both surgical treatments. With regards to these complications, authors' department has developed a new surgical technique based on a previously described technique, which provides better support to the mucoperiosteal flap and improves bone regeneration after healing. Additionally, authors' goal was to reduce the risk of nerve injury, which has been achieved thanks to a direct visualization of the inferior alveolar nerve as well as cystic lesion or the dental element. The surgical procedure described produces major advantages over the traditional alternatives, despite needing a longer operation. This technique is particularly useful in the treatment of cystic lesions that have caused considerable bone loss. It can also be utilized for cysts or impacted dental elements strictly linked to the inferior alveolar nerve. PMID:27171951

  6. Mid- and long-term clinical results of surgical therapy in unicameral bone cysts

    2011-01-01

    Background Unicameral (or simple) bone cysts (UBC) are benign tumours most often located in long bones of children and adolescents. Pathological fractures are common, and due to high recurrence rates, these lesions remain a challenge to treat. Numerous surgical procedures have been proposed, but there is no general consensus of the ideal treatment. The aim of this investigation therefore was to study the long-term outcome after surgical treatment in UBC. Methods A retrospective analysis of 46 patients surgically treated for UBC was performed for short and mid-term outcome. Clinical and radiological outcome parameters were studied according to a modified Neer classification system. Long-term clinical information was retrieved via a questionnaire at a minimum follow-up of 10 years after surgery. Results Forty-six patients (17 female, 29 male) with a mean age of 10.0 ± 4.8 years and with histopathologically confirmed diagnosis of UBC were included. Pathological fractures were observed in 21 cases (46%). All patients underwent surgery for UBC (35 patients underwent curettage and bone grafting as a primary therapy, 4 curettage alone, 3 received corticoid instillation and 4 decompression by cannulated screws). Overall recurrence rate after the first surgical treatment was 39% (18/46), second (17.4% of all patients) and third recurrence (4.3%) were frequently observed and were addressed by revision surgery. Recurrence was significantly higher in young and in male patients as well as in active cysts. After a mean of 52 months, 40 out of 46 cysts were considered healed. Prognosis was significantly better when recurrence was observed later than 30 months after therapy. After a mean follow-up of 15.5 ± 6.2 years, 40 patients acknowledged clinically excellent results, while five reported mild and casual pain. Only one patient reported a mild limitation of range of motion. Conclusions Our results suggest satisfactory overall long-term outcome for the surgical treatment of UBC

    Chondroblastomas are rare tumors that characteristically arise from the epiphyseal cartilage of long bones of the immature skeleton. Intracranial involvement is uncommon, though the squamous portion of the temporal bone is preferentially affected due to its cartilaginous origin. Patients with temporal bone chondroblastomas classically present with otologic symptoms, while primary neurological complaints are rare. In this report, we describe a 33 year-old man with a chondroblastoma of the temporal bone and an associated aneurysmal bone cyst constituting a large intracranial mass lesion who presented with new-onset seizure activity. We review issues relevant to the pathology and treatment of these lesions.

    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

    The buccal bifurcation cyst (BBC) is a rare inflammatory odontogenic cyst of unknown etiology. It typically develops on the buccal aspect of the permanent mandibular first molar and occasionally on the permanent mandibular second molar in children 4 to 14 years old. Distinct clinical findings of the BBC include involvement of a vital partially or fully erupted mandibular first or second molar, swelling in the affected mandibular molar region, delayed or altered eruption pattern of the involved tooth, and an increase in periodontal pocket depth when the affected tooth is partially erupted. Specific radiographic features include a radiolucent lesion on the buccal aspect of the tooth involving the roots to a variable extent, tilting of the involved molar so that the root apices are toward the lingual cortical plate, an intact periodontal ligament space and lamina dura, a periosteal reaction on the buccal surface, and an intact inferior border of the mandible. The histopathology of the lesion has been described as similar to a radicular or inflammatory odontogenic cyst. Most of the current literature supports simple enucleation and curettage of the cyst without extraction of the involved tooth as the treatment of choice. This report presents 3 cases of BBCs that were treated with enucleation and curettage without extraction of the involved tooth, in addition to a bone graft placed primarily or secondarily as an adjunctive treatment approach to the current therapies.

    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

    Aneurysmal bone cysts are rare benign lesions of bone tissue. They are composed of vascular spaces blood-filled and surrounded by fibrous tissue septa. They are considered as pseudo cysts because of lack of epithelial lining. Here, we describe a giant case of ABC in 12-year-old female child having a massive swelling over the right side of the mandible treated with segmental resection and reconstruction with a reconstruction plate. Case is also discussed with the review of literature. PMID:24163565

    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.

    The calcaneus is the most common tarsal affected by unicameral bone cysts (UBCs); however, the treatment of calcaneal UBCs remains controversial. The purpose of the present systematic review was to evaluate the treatment modalities for calcaneal UBCs. A systematic review was performed using clinical studies of calcaneal UBCs with a minimum of 1 year of follow-up and level I to IV evidence. Ten studies with 171 patients (181 cysts) were selected. Heel pain and radiographic cyst consolidation were the primary outcomes. A series of Z tests were used to compare the outcomes in the nonoperative and operative groups, cannulated screw and bone augmentation groups, and autografting and allografting groups. All patients treated with open curettage and bone augmentation had significant improvements in heel pain (p < .001). Only 1.1% ± 1.0% of the cysts treated conservatively had healed on radiographs compared with 93.0% ± 13.0% of the cysts after surgery (p < .001). A greater percentage of patients treated with bone augmentation had preoperative heel pain and resolution of that pain than did patients treated with cannulated screws (p < .001). Autografting had a significantly greater percentage of radiographic cyst consolidation than did allografting (97.4% ± 11.1% versus 85.1% ± 15.8%, p < .001, Z = 3.5). Objective outcomes data on calcaneal UBCs are relatively sparse. The results of the present review suggest that open curettage with autograft bone augmentation is the most effective procedure. We would encourage future comparative clinical studies to elucidate differences in UBC treatment modalities. PMID:25638776

    Baker's cysts are located in the posteromedial region of the knee between the medial belly of the gastrocnemius muscle and semimembranosus tendon. 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).

    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

    The efficacy of osteochondral allografts (OCAs) may be affected by osseous support of the articular cartilage, and thus affected by bone healing and remodeling in the OCA and surrounding host. Bone cysts, and their communication pathways, may be present in various locations after OCA insertion and reflect distinct pathogenic mechanisms. Previously, we analyzed the effect of OCA storage (FRESH, 4°C/14d, 4°C/28d, FROZEN) on cartilage quality in fifteen adult goats after 12months in vivo. The objectives of this study were to further analyze OCAs and contralateral non-operated (Non-Op) CONTROLS from the medial femoral condyle to (1) determine the effect of OCA storage on local subchondral bone (ScB) and trabecular bone (TB) structure, (2) characterize the location and structure of bone cysts and channels, and (3) assess the relationship between cartilage and bone properties. (1) Overall bone structure after OCAs was altered compared to Non-Op, with OCA samples displaying bone cysts, ScB channels, and ScB roughening. ScB BV/TV in FROZEN OCAs was lower than Non-Op and other OCAs. TB BV/TV in FRESH, 4°C/14d, and 4°C/28d OCAs did not vary compared to Non-Op, but BS/TV was lower. (2) OCAs contained "basal" cysts, localized to deeper regions, some "subchondral" cysts, localized near the bone-cartilage interface, and some ScB channels. TB surrounding basal cysts exhibited higher BV/TV than Non-Op. (3) Basal cysts occurred (a) in isolation, (b) with subchondral cysts and ScB channels, (c) with ScB channels, or (d) with subchondral cysts, ScB channels, and ScB erosion. Deterioration of cartilage gross morphology was strongly associated with abnormal μCT bone structure. Evidence of cartilage-bone communication following OCA repair may favor fluid intrusion as a mechanism for subchondral cyst formation, while bone resorption at the graft-host interface without affecting overall bone and cartilage structure may favor bony contusion mechanism for basal cyst formation.

    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.

    Background The recurrence rate after aneurysmal bone cyst (ABC) treatment is quite high despite its benign nature. In ABC therapy, curettage is the treatment of choice; en bloc excision results in a lower recurrence rate, but more extensive reconstructive surgery is needed with associated morbidity. The aim of the present study was to compare the outcomes of the two treatment options. Methods A retrospective analysis was performed on 26 patients treated for ABCs: 16 by curettage and 10 by en bloc excision. Each lesion was classified according to Enneking and patients were followed up for a mean time of 9.2 years. On follow-up, radiological examination and functional assessment (range of motion, muscle strength) were performed. Recurrence was defined as the presence of an osteolytic lesion, especially one with a tendency to grow. Results On follow-up, the following symptoms were more prevalent in the en bloc excision group compared to the curettage group: pain (en bloc 20% versus curettage 6.25%), limb length differences (en bloc 20% versus curettage 12.5%), reduced range of motion (en bloc 20% versus curettage 6.25%) and muscle strength impairment (en bloc 50% versus curettage 31.2%); however, the differences were not statistically significant (P >0.05). In the curettage group, two cases of postoperative complications and two cases of recurrence were seen, while in the en bloc excision group one case of complications was noted. Conclusions Curettage is a standard procedure in ABC management. En bloc excision is another option, albeit more technically demanding, that may be considered in recurrent lesions with extensive bone destruction or for cysts in an expendable location.

    A 29-year-old woman complained of a 3-month history of left knee pain without trauma history. X-ray showed a well-defined osteolytic lesion with a sclerotic margin in the patella and magnetic resonance imaging showed T1-low and T2-high signal intensity with different fluid level. Our impression was an aneurysmal bone cyst. At surgery, the lesion was a blood-filled cystic cavity, surrounded by a gray or brownish tissue. Hemorrhagic soft tissues with recognizable bone fragments were observed. Curettage and autogenous bone graft was done. Microscopically, sheets of tumor cells were intermingled with some areas of eosinophilic chondroid matrix. The tumor cells showed oval-shaped nuclei with moderate eosinophilic cytoplasm. Several multinucleated giant cells and blood filled cystic cavities were observed. The final diagnosis was a chondroblastoma with a secondary aneurysmal bone cyst. At the post-operative 1.5-year follow-up, grafted bones were well incorporated radiographically and there were no recurrent evidence or any other abnormal symptoms.

    Schwannoma is a benign soft tissue tumor of neural origin arising from the Schwann cells of the neural sheath. It has rarely been reported in renal or perirenal region. The preoperative diagnosis has mostly been confused with renal cell carcinoma in this location in most previous reports. We report a case that presented with a large "simple cystic" mass at the renal hilum. The preoperative differential diagnosis included hilar renal cortical cyst, renal sinus cyst, ureteropelvic junction obstruction (UPJO), or even a hydatid cyst. The final diagnosis was clinched only on histopathological examination.

    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

    Aneurysmal bone cyst (ABC) is a benign expansile bone tumor, most commonly involving the medulla of long bones. ABC rarely arises within the cortex or in the subperiosteal region, radiographically mimicking other conditions, in particular surface osteosarcomathat is low-grade in nature and may go secondary ABC changes, and telangiectatic osteosarcoma. Both of these are sometimes mistaken microscopically for primary ABC. We review the characteristics of ABC cases in our center and report four unusualsurface ABCs arising in the subperiosteal or cortical region of long bones, identified among 38 histologically proven ABCs during a four-year period in our center. The surface ABCs occurred at an older agewith a predilection for diaphysis of femur, tibia, and humerus. PMID:27200397

    A 32-year-old Japanese man presented with a 3-year history of purple reddish, and painful swelling of his fingers along with indurated erythema on his nose and ears. He was diagnosed as having sarcoidosis 8 years prior because of uveitis and bilateral hilar lymphadenopathy. X-rays of the hands revealed multiple cystic lesions in the phalanges. Histological examination of the ear revealed epithelioid cell granulomas in the dermis. Oral prednisolone 20 mg/day improved his finger swelling and pain; however, his finger deformities and erythema remain unchanged. Bone involvement is sometimes seen in sarcoidosis and the hands are the most frequently affected areas. The frequency of bone involvement is higher in lupus pernio in comparison with other types of skin sarcoidosis. Systemic corticosteroids could be the first choice of treatment to relieve the symptoms.

  17. Solid variant of aneurysmal bone cyst of the thoracic spine: a case report

    PubMed Central

    2011-01-01

    Introduction The solid variant of aneurysmal bone cyst is rare, and only 13 cases involving the spine have been reported to date, including seven in the thoracic vertebrae. The diagnosis is difficult to secure radiographically before biopsy or surgery. Case report An 18-year-old Hispanic man presented to our facility with a one-year history of left chest pain without any significant neurological deficits. An MRI scan demonstrated a 6 cm diameter enhancing multi-cystic mass centered at the T6 vertebral body with involvement of the left proximal sixth rib and extension into the pleural cavity; the spinal cord was severely compressed with evidence of abnormal T2 signal changes. Our patient was taken to the operating room for a total spondylectomy of T6 with resection of the left sixth rib from a single-stage posterior-only approach. The vertebral column was reconstructed in a 360° manner with an expandable titanium cage and pedicle screw fixation. Histologically, the resected specimen showed predominant solid fibroblastic proliferation, with minor foci of reactive osteoid formation, an area of osteoclastic-like giant cells, and cyst-like areas filled with erythrocytes and focal hemorrhage, consistent with a predominantly solid variant of aneurysmal bone cyst. At 16 months after surgery, our patient remains neurologically intact with resolution of his chest and back pain. Conclusions Because of its rarity, location, and radical treatment approach, we considered this case worthy of reporting. The solid variant of aneurysmal bone cyst is difficult to diagnose radiologically before biopsy or surgery, and we hope to remind other physicians that it should be included in the differential diagnosis of any lytic expansile destructive lesion of the spine.

    Aim: In this study, we compared and valued efficacy and safety of percutaneous echoguided sclerotherapy (PES) using 3% polidocanol with that using 99% ethanol in the treatment of patients with simple renal cysts. Materials and Methods: PES was performed for 65 simple renal cysts. Under ultrasonographic guidance the cyst was punctured using an 18 gauge needle. Sclerotherapy was performed with ethanol in 55% (36/65) of cases and with polidocanol in the remaining 45% (29/65). Patients were followed up with an ultrasound examination at 4 months, 8 months, and then at yearly intervals. A reduction of 50% or greater in cyst diameter was considered successful. Results: The median followup period for the ethanol and polidocanol groups was 24.6 and 22.8 months, respectively. The successful outcome ratio of the polidocanol group was significantly higher (90% vs. 61%, respectively) than the one of the ethanol group (P = 0.003). The partial regression of the ethanol and polidocanol groups were 6% versus 7%, respectively. The failure ratio of the polidocanol group was significantly lower (3% vs. 33%, respectively) than that of the ethanol group (P = 0.004). Neither infectious complications nor hyperthermia occurred in all treated cases. However, these methods are not completely free from symptoms. All these symptoms disappeared few hours after the procedure. Conclusions: Polidocanol is a safe and effective sclerosing agent for renal cysts, with superior clinical results than ethanol. Therefore, polidocanol can be an alternative to ethanol in sclerotherapy of renal cysts. PMID:26229316

    Extremely favorable results are obtained with the use of microcrystals of methylprednisolone acetate for treatment of bone cysts. These results have led to a complete suspension of surgical treatment of bone cysts since 1974. On the basis of these results with corticosteroids, a surgical procedure that involves an incision at the fracture location and bone graft inserted is not indicated. Results following surgery indicate a recurrence rate of approximately 25% to 30%. Since we are as yet unable to explain the mechanism by which the local injection of MPA promotes bone replacement of the cyst, the present observations only reaffirm the hypothesis (presented in our early publications) that the corticosteroid exerts a destructive action on the pathological tissue of the lesion, thus favoring a progressive process of repair. We consider this explanation valid even for lesions, e.g., eosinophilic granulomas and nonossifying fibromas, in which this method of treatment has had varying degrees of success. PMID:6804147

    Objective The purpose of this report is to describe a case of an aneurysmal bone cyst presenting as a pathologic fracture in a young athlete. Case report A 12-year-old patient presented to a chiropractic teaching clinic with a 1-week history of posterior neck pain and stiffness following a helmet-to-helmet collision in football practice. Cervical spine radiographs were taken. Lateral view radiograph demonstrated a pathologic fracture through a lytic, expansive lesion in the posterior arch of C7 with mild subluxation of the C7/T1 apophyseal joints and angulation of the C7/T1 disk space. Based upon these findings, additional diagnostic imaging was ordered. Findings on advanced imaging studies included the following: On computed tomography, the C7 lesion showed medullary destruction, cortical thinning and expansion, and a horizontally oriented fracture through the spinous and lamina. Magnetic resonance imaging studies for sagittal T2 and contrast-enhanced T1-weighted magnetic resonance images revealed fluid/fluid levels in the C7 spinous and peripheral enhancement with contrast. Outcome The patient was referred to a local hospital for treatment. The lesion was treated with resection of the posterior arch, and an aneurysmal bone cyst was confirmed histologically. The patient developed a kyphotic deformity at the site of resection and cervical instability. A subsequent fusion was performed. Conclusion Aneurysmal bone cysts are rare lesions. In this case, the initial traumatic history masked the underlying pathology. Although rare, pathologic fracture should be considered in cases of vertebral fracture in young patients. PMID:24711787

    Forty-four patient who underwent enucleation of jaw cysts were administered amoxicillin preoperatively. Specimens of venous blood (44), walls and fluids from periodontal (31) and dentigerous (13) cysts, and jawbone (26) were obtained during the operation and assayed for amoxicillin content. Measurable concentrations were found in all specimens. The levels were higher in periodontal cysts than in dentigerous cysts, and higher in maxillary bone than in mandibular bone. Since amoxicillin can easily and rapidly pass through the epithelial lining according to the change in concentration, the penetration by amoxicillin of blood/cyst wall/cyst fluid probably depends on simple diffusion.

    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

    OBJECTIVES To evaluate, in a pilot prospective randomized trial, the safety, effectiveness and radiological recurrence of retroperitoneal renal cyst decortication compared with retroperitoneal decortication with wadding using perirenal pedicled fat tissue. PATIENTS AND METHODS From March 2004 to December 2007, 40 patients with simple renal cysts were enrolled and randomized; 22 (group A) had a simple retroperitoneal decortication (SRD) and 18 (group B) a decortication with wadding of the cyst using perirenal fat tissue (RDCW). The following variables were recorded: age, gender, side, size on ultrasonography/computed tomography (CT), location, operative duration, blood loss, complications, pathology, presence or absence of flank pain, hypertension, urinary tract compression or urinary infection. The primary endpoint of this trial was to evaluate and compare the efficacy of both treatments. Secondary endpoints were safety and pain, hypertension and the resolution of urinary tract obstruction. RESULTS In all, 40 cysts were treated; there were no bilateral cysts. The mean (sd) size on CT was 11.9 (1.84) cm in group A and 12.8 (1.25) cm in group B (P = 0.1). All the procedures were completed laparoscopically and no conversion was necessary. There were no intraoperative complications. The mean (range) hospital stay was 3.4 (3-6) days. There was no statistically significant difference between the groups for all variables assessed. There was a radiological recurrence in three patients (14%) in group A, but none in group B (all successful). CONCLUSION To be completely successful, with maximum safety and to prevent recurrences in the treatment of renal cysts, RCDW is recommended when a retroperitoneal approach is chosen, especially if the cyst is located anteriorly. When symptom relief is considered, RCDW duplicates the results obtained with SRD.

    Aneurysmal bone cyst (ABC) is a locally recurrent bone lesion that has been regarded as a reactive process. Recently, a neoplastic basis in primary ABC was evidenced by demonstration of clonal chromosome band 17p13 translocations that place the USP6 (TRE2 or TRE17) oncogene under the regulatory influence of the highly active CDH11 promoter. Herein, we report CDH11 and/or USP6 rearrangements in 36 of 52 primary ABCs (69%), of which 10 had CDH11-USP6 fusion, 23 had variant USP6 rearrangements without CDH11 rearrangement, and three had variant CDH11 rearrangements without USP6 rearrangement. USP6 and CDH11 rearrangements were restricted to spindle cells in the ABC and were not found in multinucleated giant cells, inflammatory cells, endothelial cells, or osteoblasts. CDH11 and USP6 rearrangements did not correlate with recurrence-free survival, or with other clinicopathological features. CDH11 and USP6 rearrangements were not found in any of 17 secondary ABC associated with giant cell tumor, chondroblastoma, osteoblastoma, and fibrous dysplasia. These findings demonstrate that primary ABC are mesenchymal neoplasms exhibiting USP6 and/or CDH11 oncogenic rearrangements. By contrast, secondary ABC lack CDH11 and USP6 rearrangements, and although morphological mimics of primary ABC, appear to represent a non-specific morphological pattern of a diverse group of non-ABC neoplasms.

    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

    Simple cysts (SCs) of the liver are not associated with the biliary malformations in intrahepatic bile duct biliary. Seen in 0.1% to 7% of adult population, biliary malformations are more common in women. The levels of glycoprotein-like tumor markers (carbohydrate antigen (CA) 19-9) in the cysts and serum could be high. Although studies regarding CA 19-9 exist, sufficient data on cancer antigen (CA) 15-3 are not available. This case is about a 76-year-old woman who complained of painless intra-abdominal mass. The patient with a giant simple cyst extending from the gallbladder to the pelvis had preoparative CA 19-9 and CA 15-3 serum levels of 87.3 IU/L and 37 IU/L respectively. It was observed that CA 19-9 levels had decreased to 36 IU/L and CA 15-3 to 28.1 IU/L in blood samples taken in the third month after the surgery. There is a need for comprehensive studies to investigate the relationship between the size of the cyst and biomarkers (including markers such as CA 15-3) in the assesment of liver SC.

    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.

    Solitary bone cysts (SBCs) are benign, intraosseus, cystic lesions, which generally involve metaphysis of long bones during the period of skeletal immaturity. Histologic features are nonspecific, but identification of amorphous cementum-like material provides a significant diagnostic clue. This material is unique to SBC with reported frequency of 10% to 70% and has been described as an immature form of bone. We retrieved and reviewed 41 cases of SBC reported in the last 10 years. The ages of patients ranged from 4 to 64 years (mean, 16 years), with a male-to-female ratio of 3:1. Humerus and femur were the most common sites. Cementum-like matrix was observed in 26 cases (63.4%). This material was seen in different phases of deposition and progression, ultimately transforming into mature bone as seen in 4 cases. Cyst wall lining was observed in 70.7% of cases along with several other nonspecific histologic features including reactive bone formation, hemosiderin macrophages, hemorrhage, multinucleated giant cells, foamy macrophages, fibrin, cholesterol clefts, and granulation tissue. Cementum-like material in the wall of SBCs is a specific and fairly consistent finding of diagnostic significance in cases where cyst wall lining is deficient. We also histologically demonstrate, for the first time, transformation of cementum-like material into reactive and mature bone, which further validates the immature osteoid nature and finding of other authors.

    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. PMID:26668469

    Aneurysmal bone cysts (ABCs) are benign, nonneoplastic, hemorrhagic, and expansile osseous lesions that present most frequently at age younger than 20 years. Aneurysmal bone cysts typically involve long bones of extremities, thorax, pelvis, or spinal column. Skull base involvement is very rare. The authors report the case of a 23-year-old woman with ABC of the skull base and total removal of lesion with pure endoscopic endonasal approach. The patient had presented with nasal obstruction for 6 months. Physical and neurological examination findings were normal except for bilateral anosmia. Cranial magnetic resonance imaging (MRI) revealed a tumor occupying ethmoid sinuses anterior skull base that extended into bilateral frontal lobes. The patient underwent pure endoscopic endonasal surgery, and the tumor was resected gross-totally. Histologic examination revealed ABC. Consequently, ABC should be considered in differential diagnosis of skull base pathologies. Endoscopic endonasal surgical approach is a safe, minimally invasive, and effective way in the treatment of these tumors.

  15. Response of an aggressive periosteal aneurysmal bone cyst (ABC) of the radius to denosumab therapy

    Aneurysmal bone cyst (ABC), once considered a reactive lesion, has been proven to be a neoplasia characterized by rearrangements of the USP6-gene. Aggressive local growth and recurrences are common and therapeutic options may be limited due to the vicinity of crucial structures. We describe a case of a locally aggressive, multinucleated giant cell-containing lesion of the forearm of a 21-year old woman, treated with denosumab for recurrent, surgically uncontrollable disease. Under the influence of this RANKL inhibitor, the tumor showed a marked reduction of the content of the osteoclastic giant cells and an extensive metaplastic osteoid production leading to the bony containment, mostly located intracortically in the proximal radius. The diagnosis of a periosteal ABC was confirmed by FISH demonstrating USP6 gene rearrangement on the initial biopsy. Function conserving surgery could be performed, enabling reconstruction of the affected bone. Inhibition of RANKL with denosumab may offer therapeutic option for patients not only with giant cell tumors but also with ABCs. PMID:24438319

    The substance of the patella is an uncommon location for tumor occurrence and development. The present study reports a case of giant cell tumor (GCT) of the patella, combined with an aneurysmal bone cyst (ABC). To the best of our knowledge, this is the second report of GCT with ABC published in English. GCT is the most common type of benign tumor. Secondary ABC is frequently associated with GCT, but this symbiotic tumor rarely occurs in the patella. A 27-year-old male patient was examined at the outpatient clinic, and clinicopathological characteristics of the tumor were observed. X-ray and computed tomography (CT) scans revealed a lytic lesion located in the center of the right patella. Curettage, followed by autogenic and allograft bone grafting, was performed. Histopathologically, the lesion was diagnosed as a GCT with secondary ABC. No recurrence or metastasis was identified during the 1-year follow-up period. The present study reports a case of GCT with secondary ABC, and discusses the rare location and histopathological type of this tumor, in order to improve diagnosis and treatment of patellar tumors in general.

    Aneurysmal bone cyst (ABC) is an uncommon, non-neoplastic, expansive and erosive bone lesion. Considered as a pseudocyst due the lack of epithelial lining, the presence of giant cells and similarity to other lesions can make preoperative diagnosis difficult; biopsy findings must be co-related to complete clinical and radiological assessment. ABC's controversial etiopathogenesis and variable clinicopathological presentations have been widely described, but to date, there are just a few reports in literature describing the development of fibrous dysplasia (FD) from an ABC, and even less cases occurring in the jaws. We describe the case of an ABC in an 8 year-old male patient, affecting the body of the mandible, which showed accelerated growth associated to thinning of the buccal, lingual and lower cortical plates. The treatment consisted of repetitive surgical resection, curettage of the lesion and mandibular reinforcement with osteosynthesis reconstruction plates. A 16-month follow-up showed self-limitation of the overgrowth. The final histopathological and radiological analysis confirmed the FD diagnosis. PMID:27408470

    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 (β=−2.1; 95% confidence interval [95% CI], −3.3 to −0.8; P=0.002) and kidney length (β=−1.2; 95% CI, −1.9 to −0.4; P=0.003) but positively with 24-hour urinary albumin excretion (β=0.11; 95% CI, 0.01 to 0.20; P=0.03) and urine osmolality (β=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

    Introduction: We report an osteoarthritic patient with huge sub-chondral cyst-like lesions in the Anterior part of distal femur. Deep and large bone defects and severe lateral laxity due to Advanced osteoarthritis was successfully treated with semi-constrained type total knee arthroplasty with long stem. Case Report: A 70yrs old Female was admitted in our institution diagnosed with severe bilateral Osteoarthritis. The x-rays showed bone on bone Tricompartment OA Knee with Varus Malalignment. She was posted for Single Stage Bilateral Total Knee Replacement and as planned the Left Knee Was Operated first. After exposure, Proximal Tibial, Distal Femoral Cuts and measurement of extension gaps the synovium from the anterior Femur was removed and sizing was done. The AP cut was then proceeded with. We spotted a small Osteochondral Cyst in the Anterior Femur which was curretted to remove the cystic material, which is when we realised that the cyst was large and communicating with the medulary canal. The remaining Femoral preparations was done keeping in mind the risk of iatrogenic fracture and extension Stem was used in the femur. The defect was then packed cancellous bone graft. Conclusion: If suspected a Preoperative MRI should be done to exclude any sub-chondral cysts osteochondral defects and any surprise during surgery. Usually one should keep extension stems ready for difficult cases. Operating surgeon should know his implants very well, as in many standard implants extension stems can only be used when distal femur cuts are taken accordingly as 5° Valgus. Mini incision should be avoided because it may fail to reveal such surprises and may land into periprosthetic fractures. PMID:27298967

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.

    Background: Aneurysmal bone cysts are rare occurrences in the cervical spine. Surgical treatment in pediatric patients is a challenge. Complete tumor resection offers the best chance for cure. Description: Diagnosis and surgical management of an expansile aneurysmal bone cyst of the cervical spine involving all three spinal columns in a 10-year-old boy. Results: Surgical treatment included tumor excision and circumferential fusion, and produced no neurological or vascular sequelae. This approach minimizes the risk of recurrence and the possibility of postoperative spinal instability. Conclusion: Spinal instability is preferably addressed with reconstruction and stabilization. Cervical aneurismal bone cyst lesions are ideally treated with complete resection to minimize the chance of recurrence. In pediatric cases, defects created by resection should be corrected by fusion to minimize the risk of postoperative instability and growth abnormality. PMID:23526912

    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.

    Background: Typical aneurysmal bone cysts (ABCs) are osteolytic, multicystic lesions with parietal sclerosis and blood-filled cysts. In rare instances, the cystic components may be completely absent. Such solid variants in ABC (s-ABC) exhibit a solid architecture; making the clinical, radiological, and histological differentiation from other solid bone tumors like osteosarcoma (especially giant cell rich osteosarcoma) and giant cell tumor, a difficult task. Case Report: We report the case of a 45–year-old male presenting with a giant solid cervical spine lesion. Histopathology revealed solid variant of ABC, even though the radiological and fine needle aspiration cytology studies pointed toward a giant cell tumor. Conclusion: We aim to discuss the clinical, radiological, and histological findings of solid ABC (a rare benign entity) vis-à-vis the common neoplastic entities of osteosarcoma and giant cell tumor. The histopathological nuisances in making the diagnosis of s-ABC are put forth, along with its impact on management of such giant bony spinal lesions. PMID:26005581

    The authors report their experience on one patient with osteoblatoma of the odontoid process of the axis with secondary aneurysmal bone cyst. According to their knowledge, this is the first case, reported in the literature, of this kind of lesion in that particular anatomical region. Because of the rarity of this lesion, it was difficult to have a certain preoperative diagnosis. Therefore, the patient underwent a biopsy via a transoral route. The biopsy was performed over the noncalcified component of the lesion. The intraoperative histological examination showed the benign nature of the lesion. Thereafter, the lesion was totally removed, succeeding in preserving the remaining part of the odontoid process and the anterior arch of C1. In the follow-up, there was no evidence of cranio-vertebral instability. The histological examination revealed an osteoblastoma of the odontoid process of the axis with a secondary aneurysmal bone cyst. To the best of our knowledge, this is the first case reported in the literature.

    Traumatic bone cyst (TBC) occurs preferentially on the mandibular symphysis and body, but rarely on the mandibular condyle. When TBC occurs in the condylar area, it can usually be related with or misdiagnosed as a temporomandibular joint disorder. A 15-year-old female patient visited the Temporomandibular Joint Clinic with a 5-year history of pain and noise localized in the left temporomandibular joint. On imaging, a well demarked oval-shaped radiolucent lesion was observed on the left condyle head. The patient underwent cyst enucleation and repositioning of the bony window on the lateral cortex of the affected condyle head under the impression of subchondral cyst or TBC; however, no cystic membrane was found. The bone defect resolved and showed no recurrence on the serial radiographic postoperative follow-up for 43 months after surgery.

    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 is a non-neoplastic expansile lesion characterized by replacement with fibro-osseous tissue and blood-filled cavernous spaces. Involvement of the condyle is rare, and only 11 cases have been reported in English-language literature to date. Its common treatment modalities are lesion excision or condylar resection, but recurrence is high in patients treated with the former. The authors reported a 19-year-old female patient with swelling of the right preauricular region, who had a surgical curettage history in another hospital. The lesion was completely resected and the jaw was immediately reconstructed with costochondral graft with the help of SurgiCase software. The patient has been symptom-free for 6 months postoperatively.

    The aim of this study was to examine the occurrence, localization, size, ways of diagnosing and treatment of a foIlicular jaw cyst. Assessment of the patients' motives and their earlier health status was recorded, as well as their postoperative clinical course. Most of the patients were admitted because of pain, swelling, trismus, or other difficulties associated with cyst formation. Follicular cysts with persisting primary predecessor had an asymptomatic development, and were discovered after orthodontic examination or by chance. In most cases pathohistological finding and description of the formation have coincided with each other (p < 0.05). Cysts of different sizes were treated by different surgical approaches, most commonly alveolotomy and cystectomy in small cysts, while alveolotomy and cystectomy with suction or iodine tampon in large cysts. Cooperation of a dentist, an oral surgeon, a pathologist, and other specialists can lead to early diagnose and prevention of further growth of a follicular jaw cyst, thus preventing substantial bone damage.

    The reconstructive options for large expansive cystic lesion affecting the jaws are many. The first stage of treatment may involve enucleation or marsupialization of the cyst. Attempted reconstruction of large osseous defects arising from the destruction of local tissue can present formidable challenges. The literature reports the use of bone grafts, free tissue transfer, bone morphogenic protein and reconstruction plates to assist in the healing and rehabilitation process. The management of huge mandibular cysts needs to take into account the preservation of existing intact structures, removal of the pathology and the reconstructive objectives which focus both on aesthetic and functional rehabilitation. The planning and execution of such treatment requires not only the compliance of the patient and family but also their assent as customers with a voice in determining their surgical destiny. The authors would like to report a unique case of a huge solitary bone cyst that had reduced the ramus, angle and part of the body of one side of the mandible to a pencil-thin-like strut of bone. A combination of decompression through marsupialization, serial packing, and the fabrication of a custom made obturator facilitated the regeneration of the myo-osseous components of the masticatory unit of this patient. Serial CT scans showed evidence of concurrent periosteal and endosteal bone formation and, quite elegantly, the regeneration of the first branchial arch components of the right myo-osseous masticatory complex.

    The reconstructive options for large expansive cystic lesion affecting the jaws are many. The first stage of treatment may involve enucleation or marsupialization of the cyst. Attempted reconstruction of large osseous defects arising from the destruction of local tissue can present formidable challenges. The literature reports the use of bone grafts, free tissue transfer, bone morphogenic protein and reconstruction plates to assist in the healing and rehabilitation process. The management of huge mandibular cysts needs to take into account the preservation of existing intact structures, removal of the pathology and the reconstructive objectives which focus both on aesthetic and functional rehabilitation. The planning and execution of such treatment requires not only the compliance of the patient and family but also their assent as customers with a voice in determining their surgical destiny. The authors would like to report a unique case of a huge solitary bone cyst that had reduced the ramus, angle and part of the body of one side of the mandible to a pencil-thin-like strut of bone. A combination of decompression through marsupialization, serial packing, and the fabrication of a custom made obturator facilitated the regeneration of the myo-osseous components of the masticatory unit of this patient. Serial CT scans showed evidence of concurrent periosteal and endosteal bone formation and, quite elegantly, the regeneration of the first branchial arch components of the right myo-osseous masticatory complex. The microenvironmental factors that may have favored regeneration of these complex structures are discussed.

    Beginning the study of benign tumors of the bone in children and adolescents, a group of diseases that have in common the clinical aspects, evolution, and surgical treatment, genetic theory in the etiology of the solitary bone cyst, can be sustained by some cases of siblings with the same disease. This paper presents the particular case of two brothers, treated in our clinic for the same condition: solitary bone cyst of the proximal humerus. The two brothers were admitted with the same symptoms, the localization was the same. Because of the genetic studies regarding this condition, we think that it is an interesting aspect of this pathology. This study also tried to find the most appropriate approach in the treatment of these tumors. PMID:26664480

    This report presents a 13-year-old girl with an aggressive skeletal lesion involving the posterior elements of the cervicothoracic junction. The lesion was determined to be a Musculoskeletal Tumor Society grade 3 aneurysmal bone cyst based on imaging and pathologic findings. The cyst was treated with endovascular n-butyl cyanoacrylate embolization and percutaneous cryoablation with sensory and motor-evoked potential monitoring. Follow-up imaging at 16 months demonstrated significant reduction in the size of the lesion, with no evidence of recurrence.

    Objective: The aim of the study was to compare the efficacy and cost-effectiveness of single-session aspiration and ethanol sclerotherapy with laparoscopic de-roofing in the management of symptomatic simple renal cysts. Material and methods: Between March 2010 and December 2012, patients with simple renal cysts presenting with pressure and pain symptoms were divided into two groups. In Group 1 following local anesthetic administration, single session percutaneous aspiration with 95% ethanol sclerotherapy (n=38) and in Group 2 transperitoneal laparoscopic de-roofing under general anesthesia (n=42) were performed. The data were evaluated retrospectively and demographic characteristics, duration of operation and hospitalization, complication rates, cost effectiveness, radiological and symptomatic success rates at six month- follow-up were compared between the two groups. Results: The mean age and gender of the patients, cyst diamater, side and localization of the cyst and indications for intervention were similar in two groups. The median course of treatment and hospitalization were signifcantly decreased in Group 1 (respectively 33 min versus 59 min and 6 hours versus 24 hours, p<0.001). As complications in Group 1 fever in two patients (5.3%) and in Group 2 bleeding requiring transfusion in one patient (2.4%) were observed (p=0.495). Total cost was calculated as $ 131.7 in Group 1 and $ 729.8 in Group 2. After the sixth month follow-up control radiological success rates were found to be signifcantly higher in Group 2, while symptomatic success rate is similar in both groups (63.2% versus 95.2%, p<0.001; 94.7% versus 97.6%, p=0.498, respectively). Conclusion: Single-session percutaneous aspiration with alcohol sclerotherapy and laparoscopic de-roofing are safe and effective methods in the treatment of symptomatic simple renal cysts. While radiological recurrence rate was higher in single session percutaneous aspiration with alcohol sclerotherapy, however similar

    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.

    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. PMID:26893709

  9. Carpal bone kinematics in combined wrist joint motions may differ from the bone kinematics during simple wrist motions.

    PubMed

    2003-01-01

    Present in-vivo carpal kinematic studies have been limited to flexion-extension and radio-ulnar deviation. However these simple motions do not represent the full range of wrist motion employed during activities of daily living. In this study, we investigated combined carpal bone motions for one normal subject. A healthy left wrist from a 48 year old female was CT scanned in three positions: the clinical neutral position of the forearm, the pronated and maximum extended wrist posture, and the supinated and maximum flexed wrist posture. The scans were obtained using a GE8800 scanner at 120 kV and 40 mA. The voxel size was 0.234 mm X0.234 mm X1.0 mm. Principal axes registration methods were used to quantify the carpal bone kinematics. The movement of the carpal bones were described by the means of helical axis parameters. Our subject's carpal bone kinematics in the complex motions differed from the previously studied simple motions. For example, published studies have found that the primary motion of the capitate follows the global motion of the wrist during simple wrist flexion-extension. However, for the complex pronation and extension motion, the capitate rotated ulnarly out of the plane of motion. The only previous study of pisiform motion has shown that during flexion-extension the pisiform moves in the plane of motion. However during pronation and extension, the pisiform rotated ulnarly; while in flexion, the rotation was a combination of flexion and supination.

    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.

    Background and Purpose Aneurysmal bone cysts (ABCs) rarely involve the cranium and have seldom been reported in pregnancy. Clinical Presentation We describe a case of a 28-year-old woman who presented at 37 weeks of gestation with 3 months of gradually worsening vision, 10 months of proptosis, and restricted ocular motility on the left. Brain imaging revealed a multicystic enhancing mass measuring 5.9 × 5.3 × 3.7 cm, centered on the cribriform plate on the left, extending into the anterior cranial fossa superiorly as well as the left nasal cavity, maxillary, sphenoid, and frontal sinuses. Her clinical course is described in detail; 3-month postoperative imaging demonstrated no residual mass. Conclusion A literature review revealed five previous cases of ABCs associated with pregnancy. We report a rare case of a giant ABC of fibrous dysplasia involving the paranasal sinuses and anterior cranial fossa. We postulate on the possible influence of pregnancy on the clinical course.

    Soft tissue perineurioma besides its pure form may coexist with schwannoma as hybrid nerve sheath tumor (HNST) which occurs in the limbs, head and neck, trunk and occasionally colon but origination in other organ sites has not been reported. We report the first case of primary intraosseous HNST. An 18-year-old man suffered from pathological fracture of his right femur after an impact which was preceded by a similar episode two weeks previously. Plain radiograph revealed a displaced fracture in the superior diaphysis of the right femur where an expansile osteolytic lesion with relatively well defined borders was seen. Histologic examination of the curetted lesion showed a well circumscribed spindle cell neoplasm displaying predominantly storiform but focally whorled patterns. In areas, the cells possessed thin wavy spindle nuclei and delicate elongated bipolar cytoplasmic processes supported in a fibromyxoid stroma. They stained positively for EMA, claudin, CD34, collagen 4 and focally for S100 but negatively for MUC4 and BCL-2, indicative of perineurial differentiation. Situated in the periphery of some of these perineurial whorls are spindle cells bearing plump tapering wavy nuclei and palely eosinophilic cytoplasm with indistinct cell borders. They stained intensely for S100 but negatively for EMA, claudin, CD34, collagen 4, MUC4 and BCL-2, consistent with schwannian differentiation. Focally, these two varieties of cells intimately intermingled with each other. Features of aneurysmal bone cyst (ABC) formation were present but no mitotic figures, establishing the final diagnosis of primary intraosseous HNST with secondary ABC formation. The patient remained well 7 months after curettage and internal fixation of his fracture.

    Aneurysmal bone cysts (ABCs) are defined as benign cystic lesions of bone composed of blood-filled spaces. ABCs may be a secondary pathology superimposed on fibrous dysplasia (FD). Concomitant FD and ABC in relation with McCune-Albright syndrome is an extremely rare condition. Here, we report concomitant, double ABCs in bilateral occipital regions and FD from the skull base to the C2 vertebra with Chiari type 1 malformation. A 14-year-old female with a diagnosis of McCune-Albright syndrome presented with swellings at the back of her head. The lesions were consistent with ABCs and were totally resected with reconstruction of the calvarial defects. The coexistence of FD, bilateral occipital ABCs, and Chiari malformation type 1 in a McCune-Albright patient is an extremely rare condition and, to our knowledge, has not been reported to date. Exact diagnosis and appropriate surgical treatment usually lead to a good outcome.

    Epidermoid cysts are histologically benign, slow-growing congenital neoplasms of the central nervous system that may arise from retained ectodermal implants. The epidermoid lesions are generally caused during the 3rd to 5th week of gestation by an incomplete cleavage of the neural tissue from the cutaneous ectoderm, though it can also happen later in life due to introduction of skin elements by skin puncture, trauma or surgery. We present this unique case of a petromastoid epidermoid cyst associated with ipsilateral cerebellar abscesses, presenting 20 years after a penetrating trauma to the external auditory canal. Radical excision of both lesions and revision of the previous fistulous tract was performed. We present the diagnostic challenge and the operative treatment of this unique case, which to our knowledge is the first where an epidermoid cyst and an adjacent brain abscess occurred as a result of a single traumatic event.

    Background and Objectives: Renal cysts have a high prevalence in the general population, and their estimated incidence increases with age. Renal cyst aspiration (usually with sclerotherapy) or open/laparoscopic decortication is a generally effective and safe method in the treatment of symptomatic simple renal cysts. The success rates of laparoscopic decortication and percutaneous aspiration-sclerotherapy were compared to assist in the decision making for the procedure. Methods: A total of 184 patients with symptomatic simple renal cysts were treated with either laparoscopic decortication in 149 cases or percutaneous aspiration-sclerotherapy in 35 cases. The follow-up period was approximately 35 months, and the symptomatic and radiologic success rates of the 2 techniques were compared retrospectively. Results: Laparoscopic decortication was found to have high success rates, a low recurrence rate, and minimal morbidity. Percutaneous aspiration-sclerotherapy is an outpatient procedure with a minimally higher recurrence rate. Conclusion: When a symptomatic cyst is encountered and treatment of the cyst is indicated, laparoscopic decortication is a more efficient method that offers better results than percutaneous aspiration-sclerotherapy.

    2012-10-01

    Bronchogenic cysts are benign congenital malformations usually. A retroperitoneal location is extremely uncommon. We reported a case of bronchogenic cyst occurred in the retroperitoneum in a 60-year-old patient. An abdominal CT for a prostatic adenocarcinoma staging has reported this incidental lesion. Biological, radiological and histological assessment confirmed the bronchogenic cyst diagnosis. The treatment of choice for most authors is surgical excision. However, because of a low malignant transformation risk, we have chosen a follow-up with abdominal computerized tomography every 6 months. During 3 years, biological and radiological assessments have shown a stable lesion. Therefore, it seems reasonable to propose a simple radiological monitoring for bronchogenic cysts in selected patients.

    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.

  4. The Photodynamic Bone Stabilization System: a minimally invasive, percutaneous intramedullary polymeric osteosynthesis for simple and complex long bone fractures

    PubMed Central

    Vegt, Paul; Muir, Jeffrey M; Block, Jon E

    2014-01-01

    The treatment of osteoporotic long bone fractures is difficult due to diminished bone density and compromised biomechanical integrity. The majority of osteoporotic long bone fractures occur in the metaphyseal region, which poses additional problems for surgical repair due to increased intramedullary volume. Treatment with internal fixation using intramedullary nails or plating is associated with poor clinical outcomes in this patient population. Subsequent fractures and complications such as screw pull-out necessitate additional interventions, prolonging recovery and increasing health care costs. The Photodynamic Bone Stabilization System (PBSS) is a minimally invasive surgical technique that allows clinicians to repair bone fractures using a light-curable polymer contained within an inflatable balloon catheter, offering a new treatment option for osteoporotic long bone fractures. The unique polymer compound and catheter application provides a customizable solution for long bone fractures that produces internal stability while maintaining bone length, rotational alignment, and postsurgical mobility. The PBSS has been utilized in a case series of 41 fractures in 33 patients suffering osteoporotic long bone fractures. The initial results indicate that the use of the light-cured polymeric rod for this patient population provides excellent fixation and stability in compromised bone, with a superior complication profile. This paper describes the clinical uses, procedural details, indications for use, and the initial clinical findings of the PBSS. PMID:25540600

    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.

    Introduction: An epidermoid cyst is a benign cyst usually found on the skin. Bone cysts are very rare and if they appear in bone they usually appear in the distal phalanges of the fingers. Epidermoid cysts of the jaws are uncommon. Case presentation: We present a case, of a 41 year-old female patient admitted to our department because of pain and swelling in the parotid and masseteric region–left side. There was no trismus, pathological findings in skin, high body temperature level, infra-alveolar nerves anesthesia or lymphadenopathy present. The orthopantomography revealed a cystic lesion and a unilocular lesion that included mandibular ramus on the left side with 3 cm in diameter. Under total anesthesia, a cyst had been reached and was enucleated. Histopathologic findings showed that the pathologic lesion was an epidermoid cyst. Discussion: Epidermoid and dermoid cysts are rare, benign lesions found throughout the body. Only a few cases in literature describe an intraossesus epidermoid cyst. Conclusion: Our case is an epidermoid cyst with a rare location in the region of the mandibular ramus. It is not associated with any trauma in this region except medical history reveals there was an operative removal of a wisdom tooth 12 years ago in the same side. These cysts are interesting from the etiological point of view. They should be considered in the differential diagnosis of other radiolucent lesions of the jaws. Surgically they have a very good prognosis, and are non-aggressive lesions. PMID:27594757

The scoring system can guide physicians to a better selection of appropriate treatment regimens. Materials and Methods The medical records of 125 patients with bone metastases treated with RT between January 2007 and September 2010 were reviewed retrospectively. Fifteen potential prognostic factors were investigated: sex, age, Karnofsky performance score (KPS), type of primary tumor, resection of tumor before bone metastases, interval between primary tumor diagnosis and diagnosis of bone metastases, Carcinoembryonic Antigen(CEA), lung metastases before bone metastases, liver metastases before bone metastases, brain metastases before bone metastases, stage, T, N, M, and degree of cellular differentiation. Results In an univariate analysis, 10 factors were significantly associated with survival time after bone metastasis: sex, KPS, breast cancer, esophageal cancer, colorectal cancer, interval between tumor diagnosis and diagnosis of bone metastases, CEA, lung metastases before bone metastases, T-staging, and differentiation. In a multivariate analysis, 7 factors were found to be significant: sex, KPS, esophageal cancer, colorectal cancer, interval between tumor diagnosis and diagnosis of bone metastases, T-staging, and differentiation. The median survival of all patients with bone metastases after RT was 14.1 months. There were significant differences in the median survival of patients with bone metastases after RT of 4.9 months, 10.5 months, and 29.7 months in groups 1, 2, and 3, respectively (P<0.001). Conclusion According to this scoring system, the survival time of patients after bone metastasis can be estimated. PMID:27438606

    Arthroscopic reconstruction of the anterior cruciate ligament has been modernized through new surgical techniques and new materials. When tibial fixation is performed using an absorbable screw, complications may occur, such as formation of a pre-tibial cyst. The case described here is about a patient who presented an anteromedial synovial cyst in his right knee, three years after having undergone ACL reconstruction. The patient did not present any pain nor any complaints other than a mass that progressively increased in size, worsened after physical activities. Imaging examinations were requested: simple radiography of the knee and magnetic resonance. Anteromedial imaging of the knee showed a mass with well-delimited borders and internal fluid content, suggestive of a synovial cyst, with communication with the joint cavity through the tibial tunnel, without presenting enlargement or absorption of the bone tunnel. The cyst was surgically resected and the tibial tunnel occlusion was performed using a bone plug. The diagnosis of a synovial cyst was subsequently confirmed through the results from the anatomopathological examination. The patient presented good clinical evolution, with disappearance of the symptoms and a return to physical activities. PMID:26229880

    The author report a case of enteroid retroperitoneal cyst treated by enucleation. Such a lesion raises mainly the problem of histological recognition and embryological interpretation for which there are two possible theories: (1) Uptake, before sealing off of the embryo, of a cell group of endoblastic origin which develops some distance from the digestive tract. (2) Retroperitoneal course of a simple teratoma of enteroid type. Such a possibility of teratoma leaves open the possibility of malignant transformation.

    The calcifying odontogenic cyst (COC) is reported to be associated with odontoma in 24% of cases. Separation of the cases of calcifying odontogenic cyst associated with odontoma (COCaO) may lead to a better understanding of the pathogenesis of this lesion. The literature revealed 52 cases of COCaO. The male to female ratio was 1:1.9, with a mean age of 16 years. Most common location was the maxilla (61.5%). The radiographic appearance of most cases (80.5%) was a well-defined, mixed radiolucent-radiopaque lesion. Histologically, the lesions consisted of a single large cyst with tooth-like structures as an integral part, giving the impression of a single lesion. In addition to the unique histologic features, differences in gender and distribution were found between the cases of COCaO and those of simple COC. COCaO may be regarded as a separate entity and classified as a benign, mixed odontogenic tumor. The term odontocalcifying odontogenic cyst is suggested. PMID:23853467

    An epidermal cyst is a very unusual cause of a renal mass, with only three cases reported in English literature. The authors report a case of this in a 51-year-old man with left flank pain and hematuria. A 5 x 4 cm-sized cystic mass, having an irregular margin with stippled calcification, was identified in the lower pole of the left kidney. A retroperitoneal laparoscopic simple nephrectomy was performed under the assumption that it was a renal tumor. Histologically, the tumor was identical in appearance to an epidermal cyst within the skin. Aberrant ectodermal implantation during embryogenesis has been postulated as a histogenesis of intrarenal epidermal cyst. However, the present case had a history of renal stone, which was treated with extracorporeal shock wave lithotripsy. Therefore, the authors suspected the pathogenetic mechanism of this lesion was a metaplasia of traumatic origin. The diagnosis of an epidermal cyst was not made preoperatively in the present case, or in the cases described in the literature. This diagnosis should be included in the differentiation of calcified intrarenal masses.

Although its etiology is not completely known, the disease is believed to be associated with anomalies in the anatomy of the biliary tract. While being a benign unit, it is considered as a precancerosis with the risk of conversion to the biliary tract carcinoma. Radical surgical removal with biliary tract reconstruction is the only curative solution. The authors present the case report of a patient with choledochal cyst type I according to Todani

    Mechanical stimuli play a significant role in the process of long bone development as evidenced by clinical observations and in vivo studies. Up to now approaches to understand stimuli characteristics have been limited to the first stages of epiphyseal development. Furthermore, growth plate mechanical behavior has not been widely studied. In order to better understand mechanical influences on bone growth, we used Carter and Wong biomechanical approximation to analyze growth plate mechanical behavior, and explore stress patterns for different morphological stages of the growth plate. To the best of our knowledge this work is the first attempt to study stress distribution on growth plate during different possible stages of bone development, from gestation to adolescence. Stress distribution analysis on the epiphysis and growth plate was performed using axisymmetric (3D) finite element analysis in a simplified generic epiphyseal geometry using a linear elastic model as the first approximation. We took into account different growth plate locations, morphologies and widths, as well as different epiphyseal developmental stages. We found stress distribution during bone development established osteogenic index patterns that seem to influence locally epiphyseal structures growth and coincide with growth plate histological arrangement.

    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.

    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.

    We report a laparoscopic approach to the drainage and ablation of symptomatic simple renal cysts. Ten patients with chronic pain, 6 of whom failed primary aspiration, underwent laparoscopic cyst ablation: 6 had solitary renal cysts, 3 had multiple cysts and 1 had a peripelvic cyst. The approach was transabdominal in 9 patients and extraperitoneal in 1. Intraoperatively, cyst fluid was obtained for cytological examination, and cyst walls were excised and sent for pathological examination. When possible, the remaining inner cyst walls were fulgurated to prevent recurrence. Mean total operating room time was 2 hours 27 minutes and blood loss was minimal. The sole complication was a postoperative retroperitoneal hematoma, which was managed conservatively. Malignancy was diagnosed in 2 patients, each of whom had a negative preoperative aspiration. These patients subsequently underwent radical nephrectomy. All remaining patients were asymptomatic at a mean followup of 10 months. Laparoscopic ablation of renal cysts is a safe and effective alternative to open surgery in patients who have failed conservative measures. Preoperative and intraoperative evaluation for malignancy should be performed.

    Synovial cysts on the lateral side of the knee can cause pain, limitation of joint mobility, compression of the neighboring neurovascular structures, rupture leading to compartment syndrome, infection, erosion of adjacent bone, and iliotibial band friction syndrome. Open resection is commonly performed for symptomatic cysts. We describe an alternative, endoscopic approach to cyst resection. This has the advantages of minimally invasive surgery of smaller wounds, better cosmesis, and less surgical trauma. PMID:27284517

    In pathology, cysts of the retroperitoneum are usually classified together with omental and mesenteric cysts. Because of risk of complications and malignancy these cysts should be extirpated. The frequency of complications and recurrence after surgery is significantly higher for retroperitoneal cysts than for the other types mentioned above. We describe a patient with a retroperitoneal chylous cyst of three litres. Correct diagnosis was made by CT-scan and chemical analysis of cyst fluid prior to surgery. The cyst was removed completely using an intercostal, retroperitoneal approach. The postoperative course was uneventful, and no evidence of recurrence was found after six months.

  13. A biochemical study of the nature of jaw cysts (II). The role of lipids in the enlargement of cysts.

    PubMed

    Suzuki, M

    1984-10-01

    It is believed that cysts in jaws enlarge when the permeability of the cyst wall changes, that the proteins of cyst fluid increase, and that the intracystic fluid pressure on the jaw bone increases because of inflammation. On the other hand, it is also believed that cysts enlarge when a prostaglandin-like substance, which is generated in the wall, acts chemically in the resorption of the jaw bone. This investigation comprised 97 cases of various jaw cysts. The author attempted to treat 91 of these cases by the irrigation method. Lipids and related substances in cyst walls removed at operation in 15 cases, and cyst fluid were examined in all cases as follows. Their identification with IR, analyses of fatty acids with GC, and estimation of the free radical concentration by ESR were carried out. As a result, it was found that in an infected cyst wall the values of phospholipids, TBA and the free radical concentration increased, and that the value of arachidonic acid decreased. In cyst fluid there was no LCAT activity, the value of HDL-cholesterol decreased, and free cholesterol crystals were detected. After irrigation of cyst cavities, cholesterol esters were detected. In infected cyst fluid, the values for white corpuscles, TBA, and the free radical concentration increased, whereas the values of PO2, arachidonic acid, and SOD decreased. As the infection disappeared, these values were reversed. Finally the cysts diminished in size. The author assumes that jaw cyst enlargement is related to LPO and PG-like substances produced by lipid peroxidation of the cyst wall and fluid.

    Inflammatory and developmental cysts of the jaws are relatively common bone destructive lesions in the human maxillofacial skeleton but their pathogenesis is still poorly understood. In this study the role of mast cells (MC), and mast cell tryptase in particular, was evaluated in the pathophysiology of bone resorption and jaw cyst formation in different types of cysts. The distribution of MC and the amount of tryptase in histological tissue sections were determined by immunohistochemistry using monoclonal antihuman tryptase antibodies and the results were quantitated by using an image analyzing system. The amount of tryptase was further studied by Western-blotting and measurement of trypsin-like activity from the neutral salt extracts obtained from different types of jaw cysts. In contrast to control tissue, high trypsin-like activities and abundant immunoreactive tryptase were observed in the extracts of all types of cysts studied (radicular, dentigerous and keratocyst). In tissue sections the highest amount of tryptase-positive staining was observed in radicular cysts (mean 6.2% of reference area) and the lowest amount in keratocysts (mean 2.1% of reference area, P < 0.01). MC were found to be located in inflammatory cell-rich tissue areas and just beneath the cyst epithelium. Importantly, MC located at the border of bone were observed to be degranulated, indicating high activity of MC and release of tryptase at the regions of early bone destruction. Based on previous findings addressing the role of mast cell tryptase in proteolytic cascades, and the known association of MC with osteoporosis, we suggest that mast cells and mast cell tryptase may contribute significantly to jaw cyst tissue remodelling during growth of a cyst, and to the destruction of the surrounding bone, resulting in jaw cyst expansion.

    ABSTRACT Objectives The purpose of the present study was to evaluate the efficacy of adding platelet-rich plasma (PRP) to a new highly purified bovine allograft (Laddec®) in the bone regeneration of cystic bony defects augmented following cystectomy. Material and Methods Study sample included 20 patients undergoing cystectomy in which the bone defect was filled with PRP and Laddec®. All patients were examined with periapical radiographs before operation and at follow-up. After 3 months, at re-entry surgery for implant placement, bone core was taken for histological and histomorphometric analysis. Results The postoperative successive radiographs showed a good regeneration of bone in the height of bony defects with application of PRP to bone graft. By the first postoperative month, about 48% of the defect was filled, which gradually increased in each month and showed about 90% of defect-fill by 6 months. Histological and histomorphometric analysis, showed a significant presence of bone tissue and vessels, with newly formed bone in contact with anorganic bone particles. The mean volume of vital bone was 68 ± 1.6% and the mean percentage of vital bone was 48 ± 2.4%. The mean percentage of inorganic particles in tissues was 20 ± 1.2% of the total volume. All the samples analyzed did not evidence the presence of inflammatory cells. Conclusions The results of this study showed how the use of Laddec® in association with platelet-rich plasma allows bone regeneration and has a potential for routine clinical use for regeneration of cystic bony defects.

    Introduction Subchondral cysts are deeply related to the pathogenesis of osteoarthritis (OA), but the factors contributing to cyst formation are not well known. A three-dimensional analysis of subchondral cysts at the micro-structural level was conducted using high-resolution peripheral quantitative CT (HR-pQCT), and their relationships with cartilage attrition and subchondral bone microstructure were investigated. Methods Femoral heads extracted from ten female patients with hip OA were scanned using HR-pQCT at a voxel size of 41 μm. The volume fractions, numbers, and sizes of the cysts were measured in the subchondral bone region under the area of cartilage loss. Furthermore, the areas of cartilage loss, as well as the microstructure of the subchondral bones, were also measured, and their correlations with the cysts were analyzed. Results The volume fractions of cysts within subchondral bone regions varied from 2% to 33%, the numbers of cysts varied from 6 to 87, and the sizes varied from 1 mm3 to 657 mm3. There was a positive correlation between the number of cysts and bone volume (r>0.8, p<0.01). Conclusion The degree of cyst formation showed a wide distribution in number and volume, and there was a close relationship between multiple cyst formation and bone sclerosis, which might be caused by reactive bone formation that occurred around each cyst.

    Haemorrhagic mandibular cysts are quite rare and generally considered sequelae of an earlier trauma causing an overflow of blood into the bone, though a number of pathogenic theories have been put forward. Since few of these cysts involve subjective symptoms, most are discovered accidentally during radiography, while a sure diagnosis is only likely to be obtained during surgery on the discovery of a nonepithelialized cavity. The paper presents a typical case of haemorrhagic mandibular cyst which was treated by opening the cavity and scraping its walls in order to cause bleeding that would promote the growth of new bone tissue.

    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

    Orthokeratinised odontogenic cyst (OOC) denotes the odontogenic cyst that microscopically has an orthokeratinised epithelial lining. OOC is characterised by a less-aggressive behaviour and a low rate of recurrence. This report describes a case of OOC involving posterior part of the mandible that mimicked periapical cyst in a 14-year-old boy. The initial clinical diagnosis was given as periapical cyst based on the clinical and radiographical features. Enucleation of the cyst was performed and the specimen was sent for histopathological examination. A definite diagnosis of OOC was made by histopathological examination of the biopsy specimen. This case emphases on including OOC in the differential diagnosis of radiolucencies occurring in the periapical region of non-vital tooth. PMID:24099763

    Objective: To present the case of a bone lesion of the scapula in a collegiate basketball player. Background: A 19-year-old National Collegiate Athletic Association Division I male basketball player presented with pain in the posterior region of the right shoulder. During practice, he was performing a layup when his arm was forced into hyperflexion by a defender. Evaluation revealed a bone lesion involving the scapular spine and base of the acromion. Differential Diagnosis: Acromioclavicular joint sprain, subacromial bursitis, subscapular bursitis, humeral head contusion, acromial fracture. Treatment: The patient was treated for 2 months with therapeutic modalities and rehabilitation exercises. Because of persistent pain and the risk of a pathologic fracture, open surgical biopsy and bone grafting were then undertaken. Uniqueness: Most simple bone cysts affect the proximal humerus and femur, whereas our patient's lesion was in the acromial complex. Conclusions: Athletic trainers should be alert to the unusual possibility of bone cysts, which are usually identified incidentally when radiographs are obtained for other reasons. Most simple bone cysts are asymptomatic, but a pathologic fracture can occur with trauma. PMID:23725460

  10. Hemorrhagic adrenal cyst.

    1993-05-01

    Adrenal cysts are uncommon. They may be fatal if they hemorrhage and are not rapidly diagnosed. Most adrenal cysts are small and asymptomatic. When they are symptomatic, it is usually because the cyst has enlarged, causing flank discomfort, gastrointestinal complaints, and hemorrhage. Occasionally, a palpable mass may be found. It is thought that hemorrhage occurs secondary to trauma or some toxic or infectious process. The author describes a case in which a previously healthy man had a sudden hemorrhage within a benign adrenal cyst with infarction of the kidney. A discussion of adrenal cysts follows.

  11. Mesenteric and retroperitoneal cysts.

    Mesenteric and retroperitoneal cysts are rare intra-abdominal tumors. Ten new patients are presented as well as 152 other cases reported in the English literature. These 162 cases were then analyzed for significant trends. Patients under 10 years of age were significantly different from the older group with respect to a shorter duration of symptoms, a higher number of patients requiring an emergency operation, a lower number of recurrences and the location of the cyst. Patients with retroperitoneal cysts were more likely to have incomplete excision of the cyst and therefore had a higher incidence of recurrence. They also required marsupialization more often. Retroperitoneal cysts should be considered a different entity from mesenteric cysts even though they present clinically in a similar fashion. The outcome of surgical treatment is less satisfactory in patients with retroperitoneal cysts.

    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.

    Context: Popliteal synovial cysts, also known as Baker’s cysts, are commonly found in association with intra-articular knee disorders, such as osteoarthritis and meniscus tears. Histologically, the cyst walls resemble synovial tissue with fibrosis evident, and there may be chronic nonspecific inflammation present. Osteocartilaginous loose bodies may also be found within the cyst, even if they are not seen in the knee joint. Baker’s cysts can be a source of posterior knee pain that persists despite surgical treatment of the intra-articular lesion, and they are routinely discovered on magnetic resonance imaging scans of the symptomatic knee. Symptoms related to a popliteal cyst origin are infrequent and may be related to size. Evidence Acquisition: A PubMed search was conducted with keywords related to the history, diagnosis, and treatment of Baker’s cysts—namely, Baker’s cyst, popliteal cyst, diagnosis, treatment, formation of popliteal cyst, surgical indications, and complications. Bibliographies from these references were also reviewed to identify related and pertinent literature. Study Design: Clinical review. Level of Evidence: Level 4. Results: Baker’s cysts are commonly found associated with intra-articular knee disorders. Proper diagnosis, examination, and treatment are paramount in alleviating the pain and discomfort associated with Baker’s cysts. Conclusion: A capsular opening to the semimembranosus–medial head gastrocnemius bursa is a commonly found normal anatomic variant. It is thought that this can lead to the formation of a popliteal cyst in the presence of chronic knee effusions as a result of intra-articular pathology. Management of symptomatic popliteal cysts is conservative. The intra-articular pathology should be first addressed by arthroscopy. If surgical excision later becomes necessary, a limited posteromedial approach is often employed. Other treatments, such as arthroscopic debridement and closure of the valvular mechanism

    A case of mediastinal thoracic duct cyst is described; it is believed to be the first to be reported in Britain. Five surgically treated cases have been reported but in none was the diagnosis made before operation. Symptoms are caused by pressure of the cyst on the trachea and oesophagus and my be aggravted by eating a fatty meal. Differential diagnosis from other mediastinal tumours, especially bronchogenic cyst and neurofibroma, could perhaps be established before operation by lymphangiography. Images PMID:746509

    Bronchogenic cyst is a rare congenital (developmental) anomaly. It is usually asymptomatic but its enlargement and localization may cause serious symptoms. Exact preoperative diagnosis is rarely established. As a rule, it is established during histological examination of the resected specimen. We present a patient with a subdiaphragmatic retroperitoneal bronchogenic cyst in whom exact diagnosis was documented by histological examination of excised cyst. To our knowledge this is the third such case ever reported.

    Omental cyst is a rare lesion occurring primarily during childhood and young adulthood. It is closely related to mesenteric and retroperitoneal cysts, all conditions most likely being of congenital or benign neoplastic lymphatic origin. Omental cysts usually present as abdominal distention of long duration, less frequently as a palpable abdominal mass. Rarely they cause an acute abdominal surgical crisis clinically resembling appendicitis with peritonitis. Two cases are reported, one with acute and one with chronic symptoms. The clinical and radiologic features of omental cyst are reviewed in order to increase awareness of this entity.

  1. Fetal ovarian cysts: review of imaging spectrum, differential diagnosis, management, and outcome.

    PubMed

    2015-01-01

    Fetal ovarian cysts are the most common abdominal cysts observed in the female fetus but may be mistaken for genitourinary cysts, gastrointestinal cysts, lymphangiomas, or fetus in fetu. Ultrasonography (US) is the imaging modality of choice for fetal assessment, and magnetic resonance imaging is a useful problem-solving tool when uncertainty remains after careful US evaluation. At US, a fetal ovarian cyst manifests as an anechoic thin-walled cyst superior and parasagittal to the bladder. A daughter cyst may occasionally be observed and is pathognomonic for a cyst of ovarian origin. Fetal ovarian cysts may be simple or complicated and unilateral or bilateral, and they may masquerade as a solid mass when hemorrhage or torsion occurs. Complicated cysts may exhibit multiple septations, fluid-fluid levels, or mobile internal echoes. It is important to differentiate a hemorrhagic ovarian cyst from solid abdominal neoplasms that may be seen in a fetus. Recognition of the pertinent imaging findings will help radiologists distinguish fetal ovarian cysts from other fetal intra-abdominal masses in the differential diagnosis. Malignant ovarian neoplasms are rare in the fetus and neonate and thus are not considered in the differential diagnosis. The current literature on the management and outcome of fetal ovarian cysts is reviewed, with imaging studies presented from the authors' practice. Most fetal ovarian cysts resolve spontaneously; if operative intervention is required, the goal should be ovarian preservation. PMID:25763743

    Odontomas and dentigerous cysts are common findings for practicing dental professionals. However, simultaneous occurrence of pathologies like odontoma and dentigerous cyst are uncommon and their diagnosis based on the radiographic appearance alone is a challenge to overcome. They together are a potential for complications like attaining large size, root resorption, destruction of the jaw bones and sometimes neoplastic changes like ameloblastoma. This paper presents a case of complex odontoma associated with dentigerous cyst in relation to a retained deciduous tooth in the maxillary anterior region and confirming its diagnosis histopathologically.

    Mesenteric cysts are rare intraabdominal lesions of childhood that may vary in presentation from an asymptomatic mass to an acute abdomen. From 1970 to 1990, 15 children were diagnosed and treated for mesenteric cysts at Ste Justine Hospital in Montreal. The ages ranged from birth to 18 years (average age, 6 years). There were 9 boys and 6 girls. Ten patients required emergency surgery and five underwent elective surgery. The main presenting symptom was abdominal pain. Ten patients had preoperative ultrasounds that were diagnostic for a cystic mass in all patients. The second most frequent preoperative diagnosis was appendicitis. The cysts were located in the small bowel mesentery in 5 cases, the base of the mesentery with retroperitoneal extension in 4 cases, the transverse mesocolon in 4 cases, and the gastrocolic ligament in 2 cases. Operative procedures performed included complete cyst excision (9 patients), complete excision with intestinal resection (5 patients), and drainage of the cyst (1 patient). The only recurrence in this series occurred after drainage. One other patient had recurrence of a mesenteric cyst following resection performed elsewhere. Mesenteric cysts are rare in children, are usually symptomatic, and are most commonly misdiagnosed as acute appendicitis. Accurate preoperative diagnosis is possible with current ultrasonographic imaging techniques. Complete cyst resection is the procedure of choice and results in an excellent outcome.

A 45-year-old female patient presented to our hospital with complaints of back pain, weight loss, and fatigue. The computerized tomography (CT) revealed that the patient had a septated cystic lesion of about 8x7x6 cm localized in the posterior of the left kidney, in the paravertebral site causing destruction of the neighboring costa. During laparotomy, the wall of the cyst with retroperitoneal localization was partially excised and the remaining cavity was drained. The drain was removed on post-op day 5. The histopathological diagnosis was reported to be a hydatid cyst. No problems were seen during the follow-ups of the patient who was administered post-op albendazole. Hydatid cysts are an endemic disease in our country and it should be kept in mind that they also have atypical localizations.

    Four patients with splenic masses were operated upon and found to have epidermoid cysts of the spleen, a rare lesion comprising less than 10% of benign, nonparasitic splenic cysts. The patients were young and had vague, non-specific symptoms which were related to the size of the slowly enlarging splenic mass. Three patients had palpable masses. Contrast gastrointestinal studies and intravenous urography will help exclude mass lesions of the gastrointestinal or genitourinary tract. Sonar scan may confirm the cystic nature of the lesion and localize it to the spleen. A review of 42,327 autopsy records at the Los Angeles County--University of Southern California Medical Center revealed 32 benign splenic cysts found incidentally at autopsy. Hemorrhage, infection, rupture, and rarely, malignant change are complications of splenic cysts. Splenectomy is recommended to eliminate the symptoms produced by the cyst and prevent the potential complications.

    The term "intraosseous synovial cyst" is used to designate both the epiphyseal cyst-like lesions seen in patients with rheumatoid arthritis (RA) and mucoid cysts, which occur in a different setting. We report the case of a patient in whom a 4-cm cyst-like lesion developed in the left tibia 18 years after onset of RA and 6 years after osmic acid synovectomy of the left knee. Positive contrast arthrography and magnetic resonance imaging visualized a communication between the lesion and the joint space. Preexisting bone and joint lesions and increased intraarticular pressure play a major role in the genesis of cyst-like lesions in RA. In our patient, the osmic acid synovectomy may have contributed to the development of the lesion. "Synovial cyst" is a misnomer for these giant lesions, which are geodes rather than cysts. Despite their low incidence, these lesions deserve attention because they raise diagnostic and therapeutic problems.

    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.

    Formation of an abdominal chylous cyst is a rare event, predominantly occurring after spinal, vascular or urologic retroperitoneal surgery. As far as we know, the presented case is the first report in the literature of chylous cyst formation after laparoscopic fundoplication. A 57-year-old man with a history of a conservatively treated spinal compression fracture (T11/12) underwent laparoscopic fundoplication in 1996 for recurrent heartburn with insufficient response to treatment with PPI. His reflux symptoms disappeared but over the following years he developed intermittent abdominal pain in the right upper quadrant. Gastroscopy in 2002 revealed a slight compression of the distal esophagus. CT scan revealed a cystic formation next to the distal esophagus which was initially interpreted to be part of the fundoplicate itself. Aggravation of symptoms and weight loss was noted in 2006. A further CT scan revealed a 7 cm cyst along the fundoplicate and the lesser curvature of the stomach. The cyst was subsequently drained laparoscopically. Cholesterol (351 mg/d), LDL-cholesterol (263 mg/dl), triglycerides (334 mg/dl) and chylomicrons led to the diagnosis chylous cyst and the patient was put on a medium-chain triglyceride diet. After 12 weeks the discharge stopped and the drain was removed. The patient remained symptom-free for seven months but then presented again with the same complaints. This time an even larger cyst was diagnosed, extending from the lesser curvature of the stomach through the esophageal hiatus up to the right atrium. A Roux-en-Y chylous cystojejunostomy was then performed and has solved the problem up to the present. A chylous cyst may develop after laparoscopic fundoplication. If simple drainage fails, a cystojejunostomy can solve this problem.

    Background: To evaluate ultrasonographic-guided cyst aspiration and methotrexate injection in the management of simple and endometriotic ovarian cysts in selected patients. Subjects and Methods: This prospective study was conducted in the Department of Obstetrics and Gynaecology in Government Medical College and Hospital, Chandigarh, from November 2007 to October 2009. It included 132 female patients (age range, 15–72 years; mean, 38.7 years) with simple or endometriotic ovarian cysts (3.0–10.6 cm) at ultrasonic examinations. We performed puncture and aspiration followed by methotrexate injection into the cyst. All patients were followed for 12 months. None was lost to follow-up. Results: At follow-up ultrasonography, cysts had disappeared in 120 patients (90.90%) and persisted in 12 patients (9%). No major complications were observed in our study population during or after the procedure. Only 10 patients reported mild pelvic pain, and four others reported dizziness or nausea during or after the procedure. Malignant cells were not found in any of the cases at cytologic examination. We did not observe any cases of infection after the procedure. Conclusion: Ultrasonography-guided transabdominal aspiration of cyst fluid and subsequent methotrexate injection appears to be an alternative treatment for both simple and endometriotic ovarian cysts in selected cases.

    Throughout the present century phenol has been used to "sterilise" the edges of cavities left in bone after the clearance of benign tumours in order to reduce the risk of local recurrence. The results have been analysed of 165 benign bone tumours capable of local recurrence (aneurysmal bone cyst, chondroblastoma, giant cell tumour) treated with and without the use of phenol. The overall recurrence rate was 41% in 98 cases treated by simple curettage and 7% in 27 cases treated by curettage followed by the application of phenol. PMID:4086284

    INTRODUCTION. Intracranial arachnoids cysts are considered benign developmental anomalies that occur within the arachnoid membrane and generally contain clear and colourless fluid resembling cerebrospinal fluid. The prevalence of these cysts is higher in the first two decades of life, and the incidence is widely quoted as approximately 1% of all space-occupying intracranial lesions. Arachnoids cysts in the elderly person are a rare occurrence. We report the unusual presentation of a woman with an intraventricular arachnoid cyst treated with endoscopic technique. CASE REPORT. A 75-year-old woman presented with progressive hemiparesis of two years duration. Cranial MR imaging showed a right parieto-occipital intraventricular cyst with local mass effect and moderate dilatation of lateral ventricles. A right-sided burr hole was made and the arachnoids cyst was reached and cysto-ventricle shunting was realized. This was followed by a septum pellucidum fenestration. There were no complications during the surgery and the patient presented no symptoms at time of discharge. CONCLUSIONS. The neuroendoscopic approach to intraventricular arachnoid cysts was effective with few complications.

    Bronchogenic cysts are benign lesions, which are usually described at the chest level. We present here a case report of a retroperitoneal bronchogenic cyst. A 77-year-old man presented with a left retroperitoneal tumor discovered by scanner. There was no endocrine disruption. Excision of the lesion was performed and final diagnosis was a bronchogenic cyst. Current widespread use of modern radiology enables increased discovery of such "incidentalomes". In the future, pathologists will be routinely faced with this type of diagnosis, which up to now has been described as exceptional.

    Polyacrylamide based tissue mimicking phantom with embedded cysts is designed and analyzed for better understanding of cyst elastograms. Cysts filled with different fluids of varying density and bulk moduli are embedded in the phantom. Characterization is done based on parameters measured from the ultrasound B mode and elastogram of the cystic lesions. Such a phantom can serve as tool for better understanding of the elastographic appearance of cysts. Thus simple and complex cysts can be easily distinguished. It can also be used to teach a complex procedure like ultrasound guided fine needle aspiration. PMID:19163330

    During secondary bone healing, different tissue types are formed within the fracture callus depending on the local mechanical and biological environment. Our aim was to understand the temporal succession of these tissue patterns for a normal bone healing progression by means of a basic mechanobiological model. The experimental data stemmed from an extensive, previously published animal experiment on sheep with a 3 mm tibial osteotomy. Using recent experimental data, the development of the hard callus was modelled as a porous material with increasing stiffness and decreasing porosity. A basic phenomenological model was employed with a small number of simulation parameters, which allowed comprehensive parameter studies. The model distinguished between the formation of new bone via endochondral and intramembranous ossification. To evaluate the outcome of the computer simulations, the tissue images of the simulations were compared with experimentally derived tissue images for a normal healing progression in sheep. Parameter studies of the threshold values for the regulation of tissue formation were performed, and the source of the biological stimulation (comprising e.g. stem cells) was varied. It was found that the formation of the hard callus could be reproduced in silico for a wide range of threshold values. However, the bridging of the fracture gap by cartilage on the periosteal side was observed only (i) for a rather specific choice of the threshold values for tissue differentiation and (ii) when assuming a strong source of biological stimulation at the periosteum.

    Ganglion cysts have been previously described throughout the body, most commonly about the wrist, hand, knee, ankle, and feet. When symptomatic, they may interfere with joint mechanics, resulting in snapping, catching, and locking. Intratendinous ganglion cysts lack a synovial epithelial lining and are thought to develop from the mucoid degeneration of connective tissue caused by chronic irritation, chronic repetitive injury, and chronic ischemia. On magnetic resonance imaging, ganglion cysts originating from tendons, ligaments, tendon sheaths, menisci, or joint capsules appear as well-defined lobulated masses that follow simple or complex fluid signal intensity on all pulse sequences, with enhancing walls and internal septations on post-contrast images. There may be appreciable degeneration and partial tearing of the structure of origin, particularly if associated with tendons. On ultrasonography, they present as hypoechoic masses, with internal septations and lobulations of varying sizes, without significant vascularity on power or color Doppler sampling. A thin fluid neck extending from the structure of origin (tail sign), when present, is a reliable sign of a ganglion cyst. This article describes a sonographically guided technique to treat symptomatic ganglion cysts within the patellar tendon. Complete evacuation of the ganglion cyst, with disappearance of the tail sign, is considered the determining factor for a successful procedure. A similar technique can be used for the treatment of other symptomatic intratendinous ganglion cysts elsewhere in the body. To our knowledge, symptomatic intratendinous ganglion cysts within the patellar tendon and their treatment have not been previously reported.

    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.

    Accurate segmentation of abdominal organs from medical images is an essential part of surgical planning and computer-aided disease diagnosis. Many existing algorithms are specialized for the segmentation of healthy organs. Cystic pancreas segmentation is especially challenging due to its low contrast boundaries, variability in shape, location and the stage of the pancreatic cancer. We present a semi-automatic segmentation algorithm for pancreata with cysts. In contrast to existing automatic segmentation approaches for healthy pancreas segmentation which are amenable to atlas/statistical shape approaches, a pancreas with cysts can have even higher variability with respect to the shape of the pancreas due to the size and shape of the cyst(s). Hence, fine results are better attained with semi-automatic steerable approaches. We use a novel combination of random walker and region growing approaches to delineate the boundaries of the pancreas and cysts with respective best Dice coefficients of 85.1% and 86.7%, and respective best volumetric overlap errors of 26.0% and 23.5%. Results show that the proposed algorithm for pancreas and pancreatic cyst segmentation is accurate and stable.

Four years later the patient presented with another swelling with similar clinical features. It was located on the midline of the neck at the hyoid bone. Excision of cyst was done and microscopically it showed features of thyroglossal duct cyst (TDC). Two months later a new swelling was noted on the right side of the neck. A complete surgical excision was done and the lesion was diagnosed as a lymphoepithelial cyst. The purpose of this report was to analyze each of the entities that were present in this case; since, the presence of three different cervical cystic lesions in the same patient is uncommon.

She underwent laparoscopic cyst decortication complicated by a diaphragmatic injury and pneumothorax. The final pathology report described a retroperitoneal pulmonary sequestration (RPS). Urologists need to consider RPS in the differential diagnosis of a retroperitoneal cyst because of the associated morbidity of hemorrhage during surgical excision. With the widespread use abdominal imaging techniques, more cases of RPS are likely to be identified and referred for laparoscopic management.

    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

    Although ganglion cysts and stress fractures occur at many joints, the presence of both disorders at the same joint is rare. In this unusual case, a 30-year-old professional pitcher had been treated conservatively for presumed olecranon bursitis in his right (throwing) arm, but, when therapy failed, he sought additional care. A thorough workup and subsequent surgery revealed a ganglion cyst and nonunion of a stress fracture of the olecranon physis. The ganglion cyst had its origin at the fracture site, and both cyst and bone fragment were excised. The patient had a full recovery and was able to resume pitching as an instructor 18 months after surgery.

    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.

Contrary to the expected intraoperative finding of a simple stenosing pulley and ganglion cyst on a thickened flexor tendon sheath, we found fibrotic cords between an abnormal ulnar sesamoid bone at the fifth finger and the A1-pulley to be responsible for distortion of the tendon sheath and a consecutive "klicking"-phenomenon. A coherence between sesamoid bones and trigger finger has repeatedly been found on the thumb but there is no such description regarding the long fingers. PMID:16680671

    Introduction: Surgical management of large talar dome cysts is challenging due to increased morbidity by associated cartilage damage and malleolar osteotomy. The purpose of this study is to evaluate the clinical and radiological outcome of endoscopic curettage and bone graft for large talar dome cysts. Methods: This is a retrospective analysis of data for eight patients (eight feet) who were treated by arthroscopic curettage and grafting for large talar dome cysts. Seven cases were treated by posterior ankle arthroscopy as the lesion was located posteriorly while one case was treated by anterior ankle arthroscopy as the lesion was breached anteriorly. Results: The final diagnosis, was; large osteochondral lesion of talus (two cases), aneurysmal bone cyst (ABC) (two case), intra-osseous ganglion (two cases), Chronic infection in talus (one case) and angiomatous lesion of the talus (one case). The mean follow up period was 18.3 (±3.06 SD) months (range 16–25 months). The median preoperative AOFAS score was 74.5 (±5.34 SD) points. The mean postoperative AOFAS score at one year follow up was 94.6 (±2.97 SD) points. None of the patient had recurrence of the lesion during follow up. Return to normal daily activity was achieved at 11.25 (±2.37 SD) weeks. Discussion: In this short case series study, large talar dome bony cysts of different pathologies including aneurysmal bone cysts could be treated effectively by endoscopic curettage and bone grafting with no recurrence no complications during the follow-up period.

    Objective: Mechanisms of the dentigerous cyst formation from the normal eruption follicle is unknown but disturbances in the proteolytic activity have been suspected, since the growth of these cysts is accompanied by local bone destruction. The aim of the present study was to evaluate the expression of matrix metalloproteinases (MMP) in human dental dentigerous cysts and healthy dental follicles. Materials and Methods: We studied 10 patients with dentigerous cysts and 10 healthy dental follicles from the lower jaw in respect to their immunoexpression of MMPs -8, -9, -25, and -26 and tissue inhibitor of metalloproteinases -1 (TIMP-1). Results: MMP-8 was expressed slightly more in cyst epithelium than in odontogenic epithelium of healthy controls dental follicle but the difference lacked statistical difference. Other MMPs and TIMP-1 did not differ regarding the studied specimens. Conclusion: Differences in MMP expression cannot solely explain the cyst expansion suggesting the potential involvement of other osteolytic mechanisms. PMID:25386530

    Seven cases of neonatal ovarian cysts that presented over the past seven years were studied. Complications included torsion and rupture and usually occurred in cysts more than 5 cm in diameter. Surgical removal, either oophorectomy or cystectomy, was the treatment of choice. Because even cystectomy results in loss of normal ovarian tissue, and because spontaneous regression of cysts less than 5 cm in diameter can occur, a more conservative approach is now proposed. Regular ultrasonography alone is recommended if the cysts are less than 5 cm in diameter, and aspiration of the cysts followed by regular ultrasonographs if the cysts are more than 5 cm in diameter. Operation should be reserved for recurrent cysts or for those with complications. Cysts diagnosed antenatally may be aspirated in utero if there are signs of thoracic compression.

We present here the case of a 10 year old boy, who presented to us with the chief complaint of difficulty in speech for 2 years. A marble shaped swelling was seen on the base of the tongue. It was diagnosed as an intralingual thyroglossal cyst. He underwent a Sistrunk operation and the cyst was removed from the base of the tongue. Literature search revealed the rarity of this intralingual thyroglossal cyst, its atypical presentation and difference in way of management. A case report and review of literature regarding this unusual unusual entity is presented. An intralingual thyroglossal cyst is the rarest form of a thyroglossal cyst, and differs from a classical thyroglossal cyst totally in presentation and management. PMID:24427642

    Fluid filled cystic cavities are accompaniments of some cerebral gliomas. These tumoural cysts together with peritumoural vasogenic brain oedema add to the morbid effects of the gliomas in terms of mass effect and increased intracranial pressure. Although different mechanisms have been suggested as to the pathogenesis of glioma-associated cysts, it is still unclear why these cysts appear in only a limited number of cerebral gliomas while brain oedema, a probable precursor of glioma cysts, is a usual accompaniment of most gliomas. Here, the authors present a two-hit hypothesis of brain glioma cyst formation. We suggest that after the formation of vasogenic tumoural brain oedema, microvascular phenomena may lead to the formation of microcysts, which might later become confluent and grow to form macroscopic cysts. Progress in the understanding of pathogenesis of cerebral glioma cysts might set targets for treatment of brain edema and glioma cysts.

    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

    Osteoclasts are known to have a high acid phosphatase content. We have adapted the simple simultaneous mono-coupling azo-dye method of Grogg and Pearse to undecalcified bone sections. A cold embedding in a mixture of glycol and methyl methacrylate was shown to well preserve the enzyme activity. Sodium alpha-naphtyl phosphate (1 mg/ml) and fast violet B (2 mg/ml) are used in 0.1 M acetate buffer, pH 5.0. The addition of 1 mM L(+) sodium tartrate selectively inhibits the acid phosphoprotein phosphatase ("osteoblastic acid phosphatase") but not osteoclastic lysosomal acid phosphatase. Counterstaining with phosphomolybdic aniline blue WS leads to well contrasted sections, providing accurate measurements of osteoclast number.

    Second branchial cleft cysts are almost always located in the neck; thus, their presence in the nasopharynx is extremely rare. A 44-year-old man was referred to our department because a cystic mass was fortuitously found in the right lateral nasopharyngeal wall during transnasal esophagogastroscopy. He had suffered from intermittent right-sided nasal obstruction since childhood. T1- and T2-weighted magnetic resonance imaging revealed hyperintense signals. Marsupialization was performed by diode laser via an endoscopy-guided approach. No immediate postoperative complications occurred, and there was no recurrence 6 months following surgery. When a cystic lesion presents in the lateral nasopharynx, branchial cleft cyst should be considered in the differential diagnosis. In our experience, marsupialization by diode laser via an endoscopy approach is a safe and straightforward method of treating nasopharyngeal branchial cleft cyst, with no adverse effects.

We reported the case of a large retroperitoneal hydatid cyst, which is a rare situation [Hepatogastroenterology 48 (2001) 1037-9; Int Urol Nephrol 32 (2000) 41-6; J Urol (Paris) 94 (1988) 445-8]. Diagnosis was suspected with blood tests and radiological examinations. A wide incision in the right iliac fossa (such in renal graft) was performed. The cyst wall was excised partially. Before, during and following the operation, the patient was given albendazole tablets (15mg/kg per day) for 3 weeks (1 week before and 2 weeks after the surgery) with blood count and liver enzyme monitorization. Especially in the endemic areas, hydatid cyst should be remembered when evaluating cystic masses in the retroperitoneum. It can be treated successfully with surgery.

According to available data in the literature, one patients with retroperitoneal or mesenteric cyst falls among an average of 34,000-105,000 in-lying patients. Basic symptom on physical examination was a palpable tumor mass in the abdomen. In recent years correct preoperative diagnosis of these diseases has been established in 85-95 per cent of the cases with the help of echography and computer tomography. The surgical approach was determined from the possibility for total or partial removal of the cyst, which was sometimes accompanied by partial or total removal of abdominal organs involved in the pathologic process.

In the present analysis four more cases are reported and the pertinent literature is reviewed. The diagnosis is made by clinical suspicion, barium meal and/or enema, sonography and axial computerized tomography. Treatment of choice is by enucleation of the cyst, if possible. Morbidity and mortality should be very low, because of recent advances in surgery and intensive care of the patient.

    Background Accurate tests to diagnose adenocarcinoma and high-grade dysplasia among mucinous pancreatic cysts are clinically needed. This study evaluated the diagnostic utility of amphiregulin (AREG) as a pancreatic cyst fluid biomarker to differentiate non-mucinous, benign mucinous, and malignant mucinous cysts. Methods A single-center retrospective study to evaluate AREG levels in pancreatic cyst fluid by ELISA from 33 patients with a histological gold standard was performed. Results Among the cyst fluid samples, the median (IQR) AREG levels for non-mucinous (n = 6), benign mucinous (n = 15), and cancerous cysts (n = 15) were 85 pg/ml (47-168), 63 pg/ml (30-847), and 986 pg/ml (417-3160), respectively. A significant difference between benign mucinous and malignant mucinous cysts was observed (p = 0.025). AREG levels greater than 300 pg/ml possessed a diagnostic accuracy for cancer or high-grade dysplasia of 78% (sensitivity 83%, specificity 73%). Conclusion Cyst fluid AREG levels are significantly higher in cancerous and high-grade dysplastic cysts compared to benign mucinous cysts. Thus AREG exhibits potential clinical utility in the evaluation of pancreatic cysts. PMID:22333441

    Tibial cyst formation following the use of bioabsorbable interference screws in anterior cruciate ligament (ACL) reconstruction is well-described; however, cyst formation after the use of metallic interference screws is not well-documented. 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

    Isolated pancreatic hydatid cysts are a rare parasitic disease even in endemic areas. It is difficult to discriminate primary pancreatic hydatid cysts from other cystic and solid lesions of the pancreas. This is a case report of an incidental isolated pancreatic hydatid cyst. A heterogeneous cystic lesion in the body of the pancreas was identified on magnetic resonance imaging of a patient previously diagnosed patient with cholelithiasis, and because of the malignant possibility of the lesion, splenectomy with distal pancreatectomy and cholecystectomy was performed. The histopathologic diagnosis was reported as a hydatid cyst. Pancreatic hydatid cysts should be kept in mind in the differential diagnosis of pancreatic pseudocysts and cystic malignancies.

    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

    Renal cysts are the most common space occupying lesions of kidneys. These may be simple or complex. Complex renal cysts are suspicious for malignancy. Computed tomography is the gold standard in diagnosis of complex renal cysts. Negligence resulting in retained surgical foreign bodies does occur in our setup and world over. We present a unique case of retained gauze piece presenting as complex renal cyst, diagnosed four years after pyelolithotomy. A 50 year old male presented with history of on and off right lumbar pain for the last one year, along with low grade intermittent fever and weight loss. Past history revealed that he was operated for renal stones four years ago. Radio imaging including ultrasonography and CT scan revealed complex renal cyst. Patient was explored and found to have thick walled cyst with old gauze in it. PMID:26182789

    Although challenges in treatment of musculoskeletal hydatid cysts (HC) lesions have been documented, data regarding the musculoskeletal HC lesions resembling tumor is scarce. This paper presented 5 patients (3 males, 2 females) with a mean age of 41.6 years with tumor-like lesions of HC. Three of them had left ilium and acetabulum involvement, one involved left femur, and one involved left thigh muscle compartments. Pain was the main symptom and was seen in all patients. Clinical examination, radiologic evaluation, and histologic analysis were performed for diagnosis. Patients were treated through different surgical options, including simple debridement, bone cement filling with or without internal fixation, hip arthrodesis, reconstruction using hemipelvic replantation with femoral prosthesis and distal femur endoprosthetic replacement. After surgery, the operation region was washed by 20% hypertonic saline, and debridement was performed carefully without contamination. All patients received albendazole treatment. Cases were followed up 1 to 9 years for the recurrence. Walking difficulty and pain were the main symptoms during the follow-up. One patient was symptom-free. A reoccurrence in the perioperative soft tissue was detected in only one patient and control visits with antihelmintic treatment were recommended. We would like to emphasize that HC should be kept in mind for the differential diagnosis of the cystic or tumoral lesions of the musculoskeletal system, particularly in the endemic regions. Prompt diagnosis is of paramount importance for preventing destruction and complications. PMID:27384735

    The case of a woman patient with an extended prepapillary choledochal cyst and pancreaticobiliary reflux shows that it is necessary to consider the possibility of a choledochal cyst on detecting a cystic structure in the head of the pancreas (condition after acute pancreatitis); besides this, differential diagnosis will have to consider a pancreatic pseudocyst, hydrops of the gallbladder, a retroperitoneal cyst or even vascular aneurysm. If necessary, the physician should take suitable diagnostic measures before performing any percutaneous cyst drainage which he may have planned, since this may entail the risk of biliary peritonitis.

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.

    Angiomyolipoma with epithelial cysts is a rare mesenchymal tumor of the kidney that enters in the differential diagnosis of adult cystic renal neoplasms. These tumors demonstrate a slight female predominance and can present either incidentally or with symptoms, commonly flank pain and hematuria. Unlike conventional angiomyolipoma, this variant is characterized grossly by both solid and cystic areas, and histologically by the presence of single or multiple cysts lined by epithelial cells, a subepithelial "cambium-like" layer of small stromal cells with a prominent capillary vasculature, and a thick exterior wall composed of poorly formed fascicles of smooth muscle and thick-walled dysplastic blood vessels. Tumors show a distinct immunohistochemical profile and are often reactive for melanocytic markers (HMB-45 and Melan-A), as well as estrogen receptor and progesterone receptor. These tumors have an indolent clinical course, with no reports of progression or metastasis in reported cases thus far.

    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.

    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.

    Retroperitoneal, mesenteric, and omental cysts are rare abdominal tumors occurring in approximately one of 105,000 hospitalized patients. These cysts have a similar pathogenesis that primarily may be ectopic lymphatic tissue. Retroperitoneal and mesenteric cysts can occur anywhere in the area between the duodenum and rectum but are most common in the small-bowel mesentery, especially the ileum. They can appear as chronic abdominal pain, a painless abdominal mass, or acute abdomen. The most common physical finding of a retroperitoneal or mesenteric cyst is a compressible abdominal mass, movable transversely but not longitudinally; omental cysts are freely movable. Diagnostic aids include abdominal computed tomography and ultrasound. The upper gastro-intestinal (GI) tract series, barium enema examination, and intravenous pyelogram exclude GI and genitourinary cysts and tumors. Treatment of choice is enucleation; resection of the adjacent bowel may occasionally be necessary. Morbidity and mortality should be very low because of modern surgical techniques and follow-up procedures.

    Symptomatic Rathke cleft cysts (RCC) are reported in the sellar and suprasellar regions, but no case of sphenoidal RCC has been reported. We report a case of sphenoidal RCC in a 41-year-old man. The lesion was revealed by headaches and diplopia. Symptoms disappeared transiently after a spontaneous rhinorrhea but relapsed 4 months later. MR imaging showed a cystic sphenoidal lesion, isointense on T1-weighted images (WI) with peripheral gadolinium enhancement and hyperintense on T2 WI. The patient underwent surgery through a transrhinoseptal approach. The wall of the sphenoid sinus was paper-thin. The cyst contained a motor-oil-like fluid and communicated widely with the nasal fossa. Its wall was partially extracted. Symptoms and signs ceased after surgery. MR imaging performed 1 year later showed the disappearance of the sphenoidal cyst. Embryological origin of RCCs is discussed. The hypothesis of a continuum between the different epithelial cystic lesions of the sellar and parasellar region is discussed. Imaging has an important impact on the diagnosis; nevertheless, the specific characterization remains difficult. PMID:16687551

A 50-year-old female after a car crash refered chronic abdominal pain. An X-ray revealed the presence of sternal and multiple costal fractures. Abdominal ultrasonography (US) and computed tomography (CT) lead to the discovery of a retroperitoneal cyst too. As the patient was well after fractures solution, we decided to control the cyst in the time. In symptomatic cases surgery is the treatment of choice. The advent of laparoscopic surgery allows resection of these cysts to be achieved without full laparotomy.

Case presentation We report the case of a 74-year-old Turkish man with a subchondral cyst arising from the hip joint, eroding the acetabulum and located on the medial side of the iliac bone, which imitated a soft tissue tumor. This cystic lesion was resected and the results of histopathological analysis of tissue samples were found to be consistent with an osteoarthritic cyst. Conclusions The present case illustrates how an osteoarthritic subchondral cyst can grow into the soft tissue planes in the presence of destruction of the articular cartilage and subchondral bone continuity, and present as an apparent soft tissue tumor.

    Odontogenic cysts are one of the commonest bone destroying lesions of the maxillofacial skeleton, with the inflammatory radicular cyst being the commonest jaw cyst. Explants of radicular cysts produce an interleukin-1-like activity which could explain the osteolysis seen with these tumours though the cellular source of this osteolytic activity is unknown. In the present study, cytokines with known inflammatory and osteolytic activity: interleukin-1 (IL-1), tumour necrosis factor (TNF), interleukin-6 (IL-6), and the chemotactic cytokine interleukin-8 (IL-8) have been localized immunocytochemically in radicular cysts. The cellular adhesion receptors ICAM-1 and ELAM-1 have also been immunolocalized. All specimens showed positive staining for IL-1 (alpha and beta) and IL-6, with these cytokines being located in epithelial and vascular endothelial cells. Only two specimens demonstrated TNF and IL-8 staining, which was located in macrophages. All specimens demonstrated ELAM-1 staining in endothelium and ICAM-1 staining in epithelium, endothelium and mononuclear cells. These findings show that radicular cysts contain two bone-modulating cytokines, IL-1 and IL-6, and that these appear to be synthesized mainly by the epithelial cells. Cysts also contain a proportion of activated blood vessels whose endothelial cells express the cellular adhesion receptors ICAM-1 and ELAM-1.

    Hydatid cysts can be found in almost every structure in human body. Thus they can mimic numerous pathologies. Serological analyses are the best assistants in the diagnosis of hydatid cysts. But as serological investigations have limited sensitivity and specificity, they might misdirect our diagnosis. Lungs are the most common involved organ in this parasitic infection. But the brain, muscles, kidneys, bones, heart, pancreas, and rarely the retroperitoneum have also been reported to be involved. An unusual case of a sero-negative hydatid cyst located in the retroperitoneum presenting with lower urinary tract symptoms is reported in this paper.

    Mesenteric cysts are rare intraabdominal tumors. We review the diagnosis, laparoscopic management, patient's outcome and follow-up of evaluation for three cases of mesenteric cyst that presented to Istanbul University, Istanbul Medical School, Department of Surgery, from 1999 to 2002. All of the patients presented with nonspecific abdominal symptoms such as constipation, abdominal discomfort, and anorexia. Preoperative evaluation for differentiating mesenteric cyst from malignancy is made by abdominal ultrasound and computed tomography. The procedure was completed laparoscopically using three trocars in three patients. In one patient retroperitoneal resection was performed. There were no intraoperative or postoperative complications. The follow-up periods ranged from 6 to 36 months, and there were no recurrences. Currently, the surgical treatment of mesenteric cyst should be performed by laparoscopy, which offers significant advantages in terms of reduced morbidity and hospital stay. For appropriate cases in which cyst arises from mesenterium of colon, the retroperitoneal approach should be applied.

    The calcifying odontogenic cyst (COC) has been reported to be associated with odontoma in about 24% of cases. Separation of the cases of COC associated with odontoma (COCaO) may lead to a better understanding of the pathogenesis of this lesion. A screen of the literature revealed 52 cases of COCaO. The male to female ratio was 1:1.9, with a mean age of 16 years. The most common location was the maxilla (61.5%). The radiographic appearance of most cases (80.5%) was of a well-defined, mixed radiolucent-radiopaque lesion. Histologically, the lesions usually consisted of a single large cyst (which is similar to simple COC) with tooth-like structures that appear to be an integral part of the lesion, giving the impression of a single lesion. In addition to the unique histologic features, differences in gender and in distribution were found between the cases of COCaO and those of simple COC. COCaO may be regarded as a separate entity and classified as a benign, mixed odontogenic tumor. The term odontocalcifying odontogenic cyst is suggested.

    Background: The quest for ideal bone graft substitutes still haunts orthopedic researchers. The impetus for this search of newer bone substitutes is provided by mismatch between the demand and supply of autogenous bone grafts. Bone banking facilities such as deep frozen and freeze-dried allografts are not so widely available in most of the developing countries. To overcome the problem, we have used partially decalcified, ethanol preserved, and domestic refrigerator stored allografts which are economical and needs simple technology for procurement, preparation, and preservation. The aim of the study was to assess the radiological and functional outcome of the partially decalcified allograft (by weak hydrochloric acid) in patients of benign lytic lesions of bone. Through this study, we have also tried to evolve, establish, and disseminate the concept of the bone bank. Materials and Methods: 42 cases of lytic lesions of bone who were treated by decalcified (by weak hydrochloric acid), ethanol preserved, allografts were included in this prospective study. The allograft was obtained from freshly amputated limbs or excised femoral heads during hip arthroplasties under strict aseptic conditions. The causes of lytic lesions were unicameral bone cyst (n = 3), aneurysmal bone cyst (n = 3), giant cell tumor (n = 9), fibrous dysplasia (n = 12), chondromyxoid fibroma, chondroma, nonossifying fibroma (n = 1 each), tubercular osteomyelitis (n = 7), and chronic pyogenic osteomyelitis (n = 5). The cavity of the lesion was thoroughly curetted and compactly filled with matchstick sized allografts. Results: Quantitative assessment based on the criteria of Sethi et al. (1993) was done. There was complete assimilation in 27 cases, partial healing in 12 cases, and failure in 3 cases. Functional assessment was also done according to which there were 29 excellent results, 6 good, and 7 cases of failure (infection, recurrence, and nonunion of pathological fracture).

    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

    Epidermal cysts also known as epidermoid cysts, is one of the common benign tumours presenting anywhere in the body. However, epidermal cyst in the penis is very rare. This condition in children is usually congenital due to abnormal embryologic closure of the median raphe; hence, it is termed as median raphe cysts (MRCs). Penile epidermal cysts may occur in adults following trauma or surgery due to epidermal elements being trapped within closed space. During wound healing, trapped squamous epithelium, undergoing keratinisation leads to cyst formation. Here, we report a rare case of patient with a penile epidermoid cyst whose main complaints was discomfort during coitus. PMID:27437298

    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.

    SUMMARY Introduction. Nasopalatine duct cysts (NPDCs) are the most common developmental epithelial non-odontogenic cysts of the maxillae. Their origin, however, is still a source of considerable debate. Aims. The aim of this investigation is to describe and discuss the etiology, differential diagnosis, clinic-pathological characteristics as well as to report the relative frequency and distribution of nasopalatine duct cysts in population (NPDCs) with a literature’s review on the topic. Methods The retrospective study was carried out using 36 clinical cases, with histopatological confirmation for NPDC, radiographs and oral photographs. Data included age and gender of the patient, radiographic findings, etiological factors, treatment, and prognosis of NPDC. Few surgical consideration are discussed. Results The study results report a clear male predilection with a 3:1 ratio. No statistically significant correlation was observed between the size of the lesion and patient’s gender. Lesions were usually asymptomatic. All cysts were located in the anterior maxillary midline region. Panoramic X-rays and computed tomography was used to identify the lesion. Surgical treatment was performed under local anesthesia including the dissection and removal of the cyst, adopting a usually palatine approach, with an enveloping flap from 1.4 to 2.4. Conclusions The etiology of NPDC is unclear and a male predilection was observed. Simple surgical resection is recommended, followed by clinical and radiological control to ensure correct resolution of the case. PMID:23285406

    Eruption cysts are benign cysts that appear on the mucosa of a tooth shortly before its eruption. They may disappear by themselves but if they hurt, bleed or are infected they may require surgical treatment to expose the tooth and drain the contents. Here we present 2 case reports of eruption cysts presenting with different chief complaint. The treatment included incising the eruption cyst and draining the contents of the cyst. PMID:23559935

    A rare cystic lesion of the pancreas is reported. Morphologically, this unilocular cyst was filled with keratin material and lined by mature, keratinizing squamous epithelium; it was surrounded by lymphoid tissue and also focally by pancreatic tissue. Clinically, the lesion was associated with diarrhea and abdominal pain, both of which promptly disappeared after its removal. Although the histogenesis of this lesion is not known, it can be histologically differentiated from other pancreatic and retroperitoneal cysts. We propose the name "lymphoepithelial cyst" for this lesion and note that only one similar case has been described previously.

    Hydatid disease most commonly affects the liver and lungs but no organ is immune. Splenic hydatid cyst is a rare clinical entity. Although the patients are usually asymptomatic, the disease may present with secondary infection, adhesion to adjacent organs with fistulisation or rupture into abdominal cavity. We present a 67 year old women with splenic hydatid cyst. Severe adhesions and tumorlike growth were found in the retroperitoneal region. To our knowledge, retroperitoneal invasion with a splenic hydatid cyst is a very rare clinical condition. Total splenectomy was performed without complication.

    Cystic hydatid disease is an endemic disease caused by the larval form of Echinococcus spp. Isolated renal involvement is extremely rare. The treatment methods for renal hydatid disease require some form of intervention, ranging from traditional open techniques to laparoscopic techniques. Herein, we present a large hydatid cyst in the lower pole of the left kidney in a 43-year-old male patient who was treated by the "closed cyst" method via the retroperitoneal laparoscopic approach to prevent soiling of the peritoneal cavity. To our knowledge, this is the first case of a renal hydatid cyst treated by preserving the renal parenchyma by pericystectomy via the retroperitoneoscopic laparoscopic approach in an adult patient. No complications occurred during the perioperative and postoperative periods. After 9 months of follow up, the patient was asymptomatic with no evidence of clinical recurrence. Retroperitoneoscopic laparoscopic closed cyst pericystectomy can be an alternative minimally invasive treatment technique for the treatment of renal hydatid disease.

    Enteric duplication cysts (EDCs) can occur in any portion of the alimentary tract, but are most commonly associated with the small bowel and esophagus. Retroperitoneal location is really unusual. This 19-year-old female was in excellent health, but a week's abdominal pain made her search for a doctor's help. After the detailed examination, surgical intervention was performed under the impression of cystic tumor of the retroperitoneum. A retroperitoneal cystic tumor, 13.0 x 8.0 x 3.5 cm in size, without any communication with the alimentary tract was noted during the operation. Finally, EDC was diagnosed after the pathologic examination of this resected cystic lesion. To our knowledge, there have been only 6 reported cases of EDC of the retroperitoneum in the English literature. This report concerns the seventh case of retroperitoneal EDC, in an adolescent, with different clinical presentation and histopathologic findings from the previous ones.

    Objective The aim of the study was 1) to evaluate contrast enhancement patterns of subchondral cysts on magnetic resonance imaging and 2) to discuss possible radiological explanations of cyst enhancement based on existing theories of subchondral cyst formation in osteoarthritis. Materials and Methods The Multicenter Osteoarthritis (MOST) Study is a NIH-funded longitudinal observational study for individuals who have or are at high risk for knee osteoarthritis. All subjects with available non-enhanced and contrast enhanced MRI were included. The tibiofemoral and patellofemoral joints were divided in 14 subregions. The presence and size of subchondral cysts and bone marrow edema-like lesions (BMLs) were scored semiquantitatively in each subregion on non-contrast enhanced MRI from 0 to 3. Enhancement of subchondral cysts was evaluated on contrast enhanced MRI as grade 0 (absent), grade 1 (partial enhancement), or grade 2 (full enhancement). The adjacent articular cartilage was scored in each subregion on non-enhanced MRI as grade 0 (intact), grade 1 (partial thickness loss), or grade 2 (full thickness loss). Results Four hundred knees were included (1 knee per person, 5600 subregions). Subchondral cysts were detected in 260 subregions (4.6%). After intravenous contrast administration, 245 cysts (94.2%) showed full enhancement, 12 (4.6%) showed partial enhancement and 3 (1.2%) showed no enhancement. Enhancing BMLs were found in 237 (91.2%) subregions containing cysts, which were located adjacent or in the middle of BMLs. In 121 subregions (46.5%) having cysts, no adjacent full thickness cartilage loss was detected. Conclusion Most subchondral cysts demonstrated full or partial contrast enhancement, and were located adjacent or in the midst of enhancing BMLs. As pure cystic lesions are not expected to enhance on MRI, the term “subchondral cyst-like bone marrow lesion” might be appropriate to describe these lesions. PMID:19767165

    The hydatid cyst of the adrenal gland is still an exceptional localization. Only eleven cases have been described in the literature. A new case of isolate suprarenal hydatidosis is reported in one 28 years old patient, that the signs consisted in pains of the right flank and vomiting. The diagnosis has been based on the imagery, particularly the computed tomography associated to the hydatid serology, confirmed during the operation and by the pathologic examination of the resected piece. The treatment consisted in a simple cystectomy with conservancy of the gland, the operative sequelae have been simple. The interest of this cases lies in the rare feature of this hydatid localization that the diagnosis is difficult. Among the various suggested surgical methods, the simple resection of the cyst is still the best treatment that permits to keep the gland.

    Background. Hydatid cyst (HC) disease is endemic in many developing countries, like Yemen, Egypt, and Saudi Arabia, especially in the rural regions. The disease has a variable clinical courses and even might be asymptomatic for many years. Objectives. In giant and large pulmonary hydatid cysts, pulmonary resection is the usual method of surgical treatment. In this study, we aimed to evaluate the lung conservative surgery in treatment of cases with giant and large hydatid lung cysts, as an effective method of management. Patients and Methods. Between January 2009 and August 2014, a total of 148 patients with pulmonary hydatid cysts were operated and their data was reviewed retrospectively and analyzed. Out of these cases, 52 (35.14%) cysts with more than 10 cm in diameter and 36 (24.32%) cysts with 5-9 cm were regarded as giant and large hydatid lung cysts, respectively. The small cysts less than 5 cm were presented in 8 (5.4%) cases only; other cases had ruptured cysts. Preservation of the lung tissues during surgery by cystotomy and Capitonnage was our conservative surgical methods of choice. Results. Eight patients developed bronchopleural fistula (BPF); of them, 4 BPFs have healed with chest tube and physiotherapy, but in the other 4 patients reoperation was done for the closure of persistent BPF. No mortality was observed in the present study. Conclusion. We conclude that conservative surgical procedure can achieve complete removal of the pulmonary hydatid cyst. Enucleation of the intact huge cysts is safe. Careful and secured closure of the bronchial communication should be done by purse string or figure-of-8 sutures, with or without Teflon pledgets. These simple procedures are safe, reliable, and successful. PMID:27642249

    One of the rarest situations regarding an adrenal incidentaloma is an adrenal cyst. We present the case of a 61Z–year old male patient diagnosed with peritonitis. During surgery, a right adrenal tumor of 2 cm is discovered. The patient was referred to endocrinology. 6 months later the diameter of the tumor is 7 times bigger than the initial stage. It has no secretory phenotype, except for the small increase of serum aldosterone and the 24–h 17–ketosteroids. Open right adrenalectomy is performed and a cyst of 15 cm is removed. The evolution after surgery is good. The pathological exam reveals an adrenal cyst with calcifications and osteoid metaplasia. The immunohistochemistry showed a positive reaction for CD34 and ACT in the vessels and VIM in the stroma. The adrenal cysts are not frequent and represent a challenge regarding the preoperative diagnostic and surgical procedure of resection. The pathological exam highlights the major aspects.

    Maxillary cysts are a diverse group of entities that include benign and malignant odontogenic tumors. Information on the prevalence of this disease is limited. It is more common among males, and usually occurs in the second and third decade of life. The proportion of 6 to 7 year old patients with dentigerous cysts is only 9.1%. Dentigerous cysts encompass the crown of a permanent and unerupted impacted teeth. They are usually slow growing asymptomatic lesions that are not discovered until they affect surrounding organs. The aim of this study is to present an unusual case of dentigerous cyst and to inform the pediatrician about the management of a unilateral maxillary tumor in a healthy child, underlining the importance of a multidisciplinary approach of this disease.

    Duplication cyst occupying the retro- and intra-peritoneal space is a rare condition. We describe a case of duplication cyst in a 13-year-old girl who presented with abdominal pain, vomiting, and a lower abdominal mass. Plain abdominal X-ray films revealed local ileus over the lower abdomen. Ultrasonography revealed 2 double-layered cystic masses over the lower abdomen with a suspicious communicating tract. Mild hydropelvis of the right kidney was also noted. Abdominal computed tomography revealed 2 cystic lesions. One was located at the pelvic cavity just above the urinary bladder and the other was in the left retroperitoneal space. Laparotomy revealed a dumbbell-shaped intra-retroperitoneal duplication cyst with a small communicating tract. The cyst was excised without disturbing bowel continuity and the vascular supply. The patient was doing well at 1-year follow-up.

    Thirteen patients had operations to remove intracranial epidermoid cysts, and long-term follow-up was obtained. Total or nearly total tumor and capsule removal was accomplished in 7 patients during the initial operation. This group required no additional operations. The other 6 underwent subtotal tumor removal and required multiple operations for symptomatic tumor recurrence. This latter group had a poorer neurological outcome. We conclude that initial total or near-total tumor resection is highly desirable in treating intracranial epidermoid cysts, particularly in physiologically young individuals. Five patients were followed after operations to remove pure cholesterol granulomas of the petroclival bone, and 3 additional patients were followed after operations to remove tumors with combined histopathological features of both an epidermoid cyst and cholesterol granuloma. Four patients with some component of a cholesterol granuloma had concurrent middle ear infections, and 4 did not. Intracranial subtotal excision and drainage of these lesions was the initial operative management in 7 patients, 5 of whom have required multiple operations for symptomatic tumor recurrence. Therefore, we conclude that subtotal excisional procedures for tumors with histopathological features of cholesterol granulomas are not usually successful in establishing long-term cures. Total excision, as recommended for epidermoid cysts, tumors frequently confused with cholesterol granulomas when occupying the petroclival region, may be warranted for these tumors as well. We postulate that when a congenital epidermoid cyst occurs in the petroclival bone, it may incite a local inflammatory reaction, producing lesions which have the histological features of both epidermoid cysts and cholesterol granulomas.

    Epidermoid cysts, though having a variable sonographic appearance, may present with an onion peel configuration, that is, concentric rings of alternating hyperechogenicities and hypoechogenicities. The absence of vascular flow on colour Doppler sonography is also consistent with the avascular nature of these lesions. By combining these two sonographic features and the absence of biochemical tumour marker, preoperative diagnosis of epidermoid cyst is possible and may prompt a testis sparing surgery rather than orchidectomy.

    Lateral periodontal cyst (LPC) is a developmental jaw cyst of odontogenic origin. It has characteristic histopathologic features that are identical to those seen in the peripherally occurring gingival cyst of adults (GCA). The polycystic variant of LPC is termed the botryoid odontogenic cyst (BOC). The histogenetic origin of LPC is probably the rests of dental lamina in the alveolar bone. In the case of BOC, it might be that several adjacent epithelial rests simultaneously undergo cystic change and eventually form a polycystic lesion. Few previous examples of multifocal occurrence of LPC can be found in the literature.

    Neurenteric cysts in the central nervous system are rare developmental malformations. Usually the cysts are located ventral to the high thoracic or low cervical spinal cord. Only a few cases of intracranial neurenteric cysts have been reported in the literature to date. We report two cases of intracranial neurenteric cysts in the cerebellopontine angle with totally different radiographic, macroscopic, and microscopic appearance. As seen in these cases, the imaging spectrum of neurenteric cysts can be diverse, including malignancy-suspecting partial rim-enhancement or low-grade glioma features. Microsurgical therapy should include endoscopic assistance to ensure complete removal of cyst content. PMID:23397125

    Retroperitoneal cysts may be divided into those of urogenital origin: pronephric, mesonephric, metanephric and müllerian; mesocolic; teratoma; lymphatic; parasitic, and traumatic blood cysts. Müllerian cysts are thought to originate from the specialized mesothelial cells of the genital ridge and present as fimbrial cysts or broad ligament wolffian cysts. Symptoms may be absent, or the result of pressure or displacement of an organ. Diagnosis is made by x-ray studies, sonographic evaluation and, frequently, at operation. We report a case of a 14-pound cyst arising from the right broad ligament and partially obstructing the right ureter that was removed surgically.

    Bronchogenic cysts are among developmental disorders of the primitive foregut which are typically found above the diaphragm. Bronchial cysts discovered in the abdominal cavity or retroperitoneum are extremely rare. We present a rare case of a retroperitoneal bronchogenic cyst which was incidentally detected after a wrestling injury in a 23-year-old man who had a negative medical history. Although initial imaging studies suggested an adrenal tumor, histopathological analysis provided a definite diagnosis of bronchogenic cyst. Though rare, bronchogenic cysts must be considered in the differential diagnosis of retroperitoneal cystic lesions. This is the first case of a retroperitoneal bronchogenic cyst reported in Iran.

    The authors reports a case of a young woman suffering from mesenteric cyst. The incidence of these lesions is 1 to 100,000 admissions in adult patients and 1 to 20,000 admissions in pediatric age. These cysts, with retroperitoneal and omental cysts, have a similar etiopathogenesis as lymphatic ectopic tissue. In the majority of cases these cysts are asymptomatic and often the diagnosis is intraoperative. In this case the cyst was removed successfully with laparoscopic approach. This mini-invasive method allows a complete and radical excision of the cyst and reduces postoperative hospital stay and morbidity.

    We describe a seminal case report of a child with a tethered cord syndrome secondary to the unusual constellation of a split cord malformation, lumbar myelomeningocele, and coexisting neurenteric cyst. A 17-year-old adolescent girl with a several-month history of myelopathy and urinary incontinence was examined whose spinal MRI scan demonstrated a type II split cord malformation with a large bone spur and an intradural neurenteric cyst in addition to lumbar myelomeningocele. Untethering of the spinal cord was achieved via a lumbar laminectomy. Pathological examination confirmed the intradural cyst to be a neurenteric cyst. Postoperatively there was stabilization of the neurological symptoms. Prophylactic surgery with total resection of the neurenteric cyst when feasible and spinal cord un-tethering appears to be associated with excellent outcomes.

    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.

    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.

    The aneurysmal bone cyst (ABC) is a benign tumour of children and young adults. It represents approximately 1-2% of all bone tumours. The ABC may develop on all skeletal bones, but the proximal end of the femur is the most common location. The authors report a ABC femoral neck in a child of 13 years. This location is pretty special. Indeed, the fragility of the femoral neck due partly to the pathology itself and secondarily curettage requires a judicious attitude surgical (excisional curettage + bone graft + screw) to prevent the risk of high local recurrence and pathological fracture.

    Pycnodysostosis is a rare autosomal recessive disorder caused by mutations in the cysteine protease Cathepsin K gene located on chromosome 1q21. It has a well characterized skeletal phenotype which include short stature, generalized increased bone density with propensity of fractures, open calvarial sutures and fontanelle, dental abnormalities, obtuse mandibular angle, resorption of lateral end of clavicle, acro-osteolysis, and in some cases visceromegaly. Central nervous system involvement is very rare and porencephalic cysts has been reported only once, the cause being hypothesised to be an imbalance between the growing brain, its vascular supply and intraventricular fluid pressure. We had a patient with bilateral frontal lobe porencephalic cysts; the patient presenting with complex partial seizures. Cathepsins have been found to be involved in neurological diseases and role of proteases has been well established in gliosis. PMID:25002775

    Background: Management of popliteal cyst is controversial. Owing to high failure rates in open procedures, recent trend is towards arthroscopic decompression and simultaneous management of intraarticular pathology. We retrospectively analysed clinical results of symptomatic popliteal cysts after arthroscopic management at 24 month followup. Materials and Methods: Retrospective analysis of hospital database for patients presenting with pathology suggestive of a popliteal cyst from June 2007 to December 2012 was done. Twelve cases of popliteal cyst not responding to NSAIDS and with Rauschning and Lindgren Grade 2 or 3 who consented for surgical intervention were included in the study. All patients underwent arthroscopic decompression using a posteromedial portal along with management of intraarticular pathologies as encountered. Furthermore, the unidirectional valvular effect was corrected to a bidirectional one by widening the cyst joint interface. The results were assessed as per the Rauschning and Lindgren criteria. Results: All patients were followed for a minimum of 24 months (range 24-36 months). It revealed that among the study group, six patients achieved Grade 0 status while five had a minimal limitation of range of motion accompanied by occasional pain (Grade 1). One patient had a failure of treatment with no change in the clinical grading. Conclusion: Arthroscopic approach gives easy access to decompression with the simultaneous management of articular pathologies. PMID:27053804

    The choledocal cyst is a defect of the biliary extrahepatic route, the incidence is 1 in 100-150,000 newborns. This paper reports the case of a female newborn with choledocal cyst detected prenatally, from a 32-year-old mother, 2nd term pregnancy, who was diagnosed in the routine obstetric ultrasound as an abdominal fetal cyst. An anatomic obstetric ultrasound confirmed the diagnosis that was defined of a probable hepatic origin. Newborn was delivered at 39 weeks by caesarean section, with weight of 3,980 g and Apgar score 9-9 in conventional time. Newborn presented a maxim bilirubin level of 16 mg, controlled with phototherapy; the hepatic function was normal. Ultrasound showed a choledocal cyst which measured 50 x 49 x 48 mm, with dilatation of the hepatic common conduct, the gall bladder was normal. The abdominal scan reported a cystic mass in the middle abdominal region of 44 x 53 x 52 mm confirming a choledocal cyst. The diagnosis was confirmed after surgery. Patient had a satisfactory post-surgical evolution. PMID:23596735

We describe 10 cases of post-traumatic respiratory epithelial cyst (age range 23 - 82), presenting a mean of 17.4 years after their original trauma; and 3 congenital cases (age range 17-34). All but one case underwent surgical excision of the cyst and its lining, along with any surgical implant within the cyst. Two were recurrent after incomplete excision. Three presented with acute infection within the cyst. Respiratory epithelial orbital cysts are probably commoner than the paucity of published reports would suggest. Post-traumatic cysts often present many years after trauma, and may become secondarily infected. Complete surgical removal is recommended to prevent future recurrence. PMID:27468088

    The immunohistological features and surgical treatment of an intramedullary ependymal cyst in the conus medullaris is presented. An intramedullary ependymal cyst is a rare lesion of dysembryoplastic origin. There have been only seven patients reported with pathologically proven ependymal cysts in the conus medullaris. A 64-year-old woman reported pain and numbness in both thighs and feet. Neither sensory nor motor impairment was present in the lower extremities. MRI revealed a cyst on the right side of the conus medullaris, compressing the spinal cord upward. Clinical signs and symptoms disappeared following surgical resection of the cyst. Histological examination showed that this cyst was lined with a single layer of tall columnar or low cuboidal cells on fibrous connective tissue. The basement membrane was absent in the cyst wall. Reactivity to CAM5.2 and AE1/AE3 anti-keratin antibodies suggested that the cyst was of neuroepithelial origin. No recurrence has been noted 3 years after surgery.

The most common primary site is liver (75%) followed by lungs (5-15%) and other organs constitute 10-20%. Peritoneal hydatid cysts are very rare especially primary peritoneal hydatid. Secondary peritoneal hydatid cysts are relatively common, which usually occurs due to rupture of primary hepatic hydatid cyst.

    Cystic lesions of the parotid gland are not common and are often erroneously diagnosed as benign tumors. Lymphoepithelial cysts are only rarely diagnosed in the parotid gland. The term "lymphoepithelial cyst" is used because it is a descriptive term and takes no account of the origin and development of these cysts. An origin from sequestered lymph nodes epithelium in the parotid gland may be a feasible explanation for the origin of these cysts.

We induced anesthesia and paralysis with 200 mg propofol, 50 μg fentanyl and 9 mg vecuronium. Direct laryngoscopy with a Macintosh 3 blade revealed a 2x2 cm cyst, pedunculated, arising from the right side of the vallecula preventing the endotracheal intubation. While the patient remained anesthetized, we urgently consulted an otolaryngologist and aspirated the cyst with a 22-gauge needle and syringe under direct laryngoscopy. We aspirated 10 cc of liquid content. This was followed by an uneventful tracheal intubation with a 9.0 enforced spiral cuffed tube. An alternative to fiberoptic intubation may be careful cyst aspiration to facilitate the intubation.

    The paradental cyst is commonly misinterpreted when associated with atypical clinical and radiographic characteristics, in turn causing diagnostic problems. For this reason, the study of the differential diagnosis of this lesion has become extremely important. In addition, the correlation of clinical, histologic, and radiographic findings are also of great value in obtaining accurate diagnoses. The minor variations in the clinical appearance of paradental cysts make it feasible to consider the two main groups of cysts separately: those associated with 1st and 2nd permanent molars of the mandible and those associated with the 3rd mandibular molar. Moreover, this distinction in localization may well dictate the necessary treatment. Bearing in mind the minor clinical variations, the present article aims to discuss the differential diagnosis of this lesion and its different possible treatments by presenting a case report to illustrate the findings.

    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 laparotomy. 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.

    Hydatid disease is one of the common parasitic afflictions seen in sheep rearing areas of world, with certain areas in northern India showing a very high incidence. It is caused by the larval/cyst stage of Echinococcus granulosus, in which humans are an intermediate host. The cysts are located in liver 75% times, lungs 15%, other organs 10%. Isolated involvement of kidneys is rare and forms 2-4% of cases. The treatment usually requires some form of intervention ranging from minimally invasive percutaneous aspiration techniques to laparoscopic and the maximally invasive, open techniques. Herein, we describe two cases of isolated renal hydatid cysts that were treated successfully by retroperitoneal laparoscopic approach to prevent the soiling of peritoneal cavity. One of the cases had a preoperative diagnosis of simple renal cyst. No complications occurred at peroperative and postoperative periods. The patients were given 3 cycles of Albendazole (10 mg/kg in two divided doses), each for a period of four weeks followed by a weeks rest. The patients are under strict follow-up and no recurrence has been documented yet.

Usually it is recognised accidentally, with US or CT examinations performed for other reasons. In case the general condition of the patient is satisfactory, the surgical removal of such a tumour is recommended, since it is almost impossible to differentiate from more harmful lesions by CT or US examination, and if there are no tumour cells on the smears obtained by fine needle aspiration, there is always the doubt of sampling error.

    Intraperitoneal or retroperitoneal cystic structures in the newborn appear with a variable clinical picture and in the case of intra-abdominal cysts, surgery is performed mostly on an emergency basis. In such cases the exact preoperative diagnosis is difficult and is seldom made. With early laparotomy, extensive small bowel resection can usually be avoided. Retroperitoneal lesions are mostly of renal origin; in such cases, preoperative diagnosis is easy, being based on specific examinations. In the year 1973, 5 newborns with an intraperitoneal or retroperitoneal cyst have been treated surgically. In this series, one infant died after resection of 90% of the small bowel.

    The aims of this article are to present a case demonstrating the connection between palatoradicular grooves and inflammatory collateral cysts and to discuss the related nomenclature. Radiographs in a 21-year-old man revealed a radiolucent, unilocular, well-defined area near the vital maxillary right lateral incisor and canine. Palatal swelling was present, and a 6-mm-deep periodontal pocket was found at the palatal surface of the right lateral incisor. The differential diagnoses were keratocystic odontogenic tumor, developmental lateral periodontal cyst, and inflammatory lateral periodontal cyst. The area was explored surgically, and the lesion was excised. Surgical exploration revealed a palatoradicular groove, which was scaled and planed with the aid of manual curettes with the intention of creating a flat surface to promote insertion of the periodontal fibers. Histopathologic analysis revealed that the lesion was an inflammatory cyst. The presence of a palatoradicular groove can put the periodontium at risk because a resulting lack of fiber insertion makes oral hygiene difficult. This established inflammatory process can initiate development of an inflammatory collateral cyst that may be misdiagnosed, hindering successful management. In this case, bone grafting and placement of a resorbable membrane were used to promote bone formation and subsequent sealing of the periodontal space. PMID:27148666

    Fifty-five patients, (30 Rheumatoid Arthritis (RA) and 25 Osteoarthritis (OA], with knee synovial effusion and popliteal cysts, visualized through arthrograms, were studied. A relationship was sought between radiological findings and area of the cysts, measured through a millimeter grid. Ten radiological parameters were graded and summed up to obtain a "total knee score". A "total geode score" was also obtained by scoring, separately, the geodes. In addition two specific indexes were used--for comparison--the erosive index, modified after Berens and Lin, in RA and the Kelligren's index in OA. In RA a statistically significant, inverse correlation was found between the x-ray scores and the area of the cysts, while such a relationship was not observed in OA. However, only a third of the cysts accounted for the inverse relationship in RA. Furthermore, two control groups of RA and OA patients revealed a striking association between degree of radiological damage and frequency of popliteal cysts. Therefore, the hypothesis that popliteal cysts might have a protective effect against the articular-bone damage in RA, can be held only in few cases.

    Achieving complete resolution of spinal hydatid cyst disease is quite challenging when bone is involved. Many authors reported the poor outcome of posterior decompression and laminectomy for intraosseous spinal hydatid disease. In an attempt to avoid a similar poor outcome, hydatid cysts were reached via both anterior and posterior surgical approaches in our patient. A 73-year-old man presented with complaints of low back and right leg pain. Symptoms or signs of systemic hydatid cyst disease were absent. MRI demonstrated a cystic lesion in the presacral/retroperitoneal region, involving the body of the sacrum and sacral canal. Computed tomography images showed enlargement of the sacral foraminae. The multiseptated cysts and their contents were isodense with cerebrospinal fluid. The cysts were removed via an anterior extraperitoneal approach, using a paramedian vertical incision, and then were also approached posteriorly via bilateral S1 hemilaminectomy. No neurological deficits occurred following surgery. The patient's symptoms completely disappeared after this combination of aggressive surgery and antihelminthic therapy. The application of both anterior and posterior approaches to intraosseous sacral hydatid cysts may be preferred when faced with hydatid disease in this location.

    Retroperitoneal cysts are rare, usually asymptomatic, lesions. We present the case of a 42-year-old woman with an asymptomatic abdominal mass. The mass excised at our district hospital was found in the retroperitoneum. Histologically, the cyst was lined with benign Mullerian-type epithelium. The classification, aetiology and clinical manifestations of retroperitoneal cysts are discussed. Retroperitoneal cysts present as an acute abdomen in only a minority of cases. Ultrasound is the most reliable test for their detection, usually followed by computed tomography and/or an upper gastrointestinal series. Optimally, these cysts should be completely excised.

    Mesenteric cysts are rare intra-abdominal lesions. We present a case of a mesenteric cyst that was discovered by abdominal computed tomography (CT) and excised by retroperitoneoscopic surgery. There have been 10 reports of excision of mesenteric cysts by laparoscopy in the literature, but retroperitoneoscopic resection of such cysts has not been reported. This case suggests that when a mesenteric cyst arises from the ascending or descending colon, the retroperitoneal approach has a lower risk of traumatizing the bowel than does the laparoscopic intra-abdominal approach, and it does not have to compress other intra-abdominal organs.

    Retroperitoneal contamination may occur during the natural history of hydatid disease. Primary hydatid cyst of the retroperitoneum is extremely rare. The authors report a case of a giant retroperitoneal hydatid cyst. Clinicians and surgeons must be aware of this possibility and follow a policy of nonsystematic puncture of an abdominal cyst and avoid spillage during surgery. Symptoms are related to the size, location, or ensuing complications of a cyst. Its occurrence should be strongly suspected ahead of any abdominal cyst, especially in an endemic area, where it may act as a parasite. Total and careful surgical excision is the gold-standard therapy.

    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.

    Respiratory obstruction and stridor in infants and children are not uncommon. A rare cause of these sometimes life-threatening symptoms is the congenital saccular cyst. Objectives: We present the case of a 5-year-old girl with a cervical tumor, which appeared after a laryngeal endoscopic surgery of a saccular cyst with two relapses and a particular local evolution of its recurrence through the cricothyroid membrane. Material and method: The patient data has been reviewed over the entire follow-up period and a thorough an analysis of her investigations and surgery was performed. Results: The unusual evolution of this case was marked by an atypical exteriorization – not found in the published literature. The surgical approach was external, by paramedian thyrotomy, with no further long-term recurrence. Conclusions: An accurate diagnosis of saccular cysts can be made with the help of medical history, by an endoscopic visualization of the lesion and by the CT-scan imaging of the cervical region. Sometimes, saccular cysts can extend beyond laryngeal limits, determining fluid-filled tumors in the cervical region. PMID:27453755

    The authors report a case of adventitial cyst of the abdominal aorta. This would seem to be the first time that a cyst has been reported in the literature with this localization. A 54 year old female patient was treated surgically for a suspected aneurysm of the abdominal aorta. Her antecedents included syphilis treated with bismuth. The condition began with a lumbago with no clearly defined etiology. An abdominal X-ray without preparation visualized a calcified abdominal tumor in a retroperitoneal position, apparently attached to the aorta. Arteriography showed that the tumor was excluded from the circulation. Surgical exploration of the aorta demonstrated a cystic tumor, which was resected. A review of the literature concerning the pathology of arterial cysts shows no previous cases of aortic cyst. On the other hand, references to identical anomalies of the iliac, femoral, popliteal and radial arteries provide grounds for discussion of the etiology of this aortic disease. The macroscopic data and histological studies suggest a phenomenon of cystic degeneration rather than a constitutional anomaly of the artery, or, in this particular case, an anomaly connected with syphilitic lesions.

    Paralabral cyst of the shoulder joint can be observed in 2% to 4% of the general population, particularly in men during the third and fourth decade. On average, these cysts measure 10 mm to 20 mm in diameter and are located preferentially on the postero-superior aspect of the glenoid. The MRI has increased the frequency of the diagnosis of paralabral cysts of the shoulder joint. Paralabral cysts of the shoulder joint usually develop in the proximity of the labrum. The relationship between shoulder instability and labral tears is well known, however, the association of shoulder instability with a paralabral cyst is rare. Shoulder instability may cause labral injury or labral injury may cause shoulder instability, and then injured tear develops paralabral cyst. In our patient, the inferior paralabral cyst may be associated with inferior labral tears and instability MRI. PMID:20514270

    Reinke edema is one of the common cause of dysphonia middle-aged population, and severe thickening of vocal folds require surgical treatment. Smoking plays a major role on etiology. Vocal fold cysts are also benign lesions and vocal trauma blamed for acquired cysts. We would like to present 3 cases with vocal fold cyst related with Reinke edema. First case had a subepidermal epidermoid cyst with Reinke edema, which could be easily observed before surgery during laryngostroboscopy. Second case had a mucous retention cyst into the edematous Reinke tissue, which was detected during surgical intervention, and third case had a epidermoid cyst that occurred 2 months after before microlaryngeal operation regarding Reinke edema reduction. These 3 cases revealed that surgical management of Reinke edema needs a careful dissection and close follow-up after surgery for presence of vocal fold cysts.

    A 5-month-old boy who was diagnosed as having hydrops fetalis at 25 weeks' gestation had severe ascites of unknown origin. At the age 12 months, ultrasonography and computed tomography showed multiple cysts in the spleen that were increasing in size rapidly. Splenectomy resulted in complete disappearance of the ascites. These cysts were diagnosed as mesothelial cysts because the cell lining of the splenic cysts stained positively with alcian blue and cytokeratin. The boy's mother had undergone splenectomy for splenic and retroperitoneal lymphangiomas at 4 years of age. Histological reevaluation showed that the lining of her splenic cysts had the same mesothelial components as her son's. Their chromosomal assay showed normal karyotypes. Mesothelial cyst of the spleen appears similar to splenic lymphangioma morphologically; however, bleomycin and OK-432 were not effective. Familial splenic mesothelial (epidermoid) cysts have been reported in three sets of siblings, but this is the first report of their occurrence in mother and son.

    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.

    Hydatid disease is a zoonosis that can involve almost any organ in the human body. After the liver, the lungs are the most common site for hydatid disease in adults. Imaging plays a pivotal role in the diagnosis of the disease, as clinical features are often nonspecific. Classical radiological signs of pulmonary hydatid cysts have been described in the literature, aiding in the diagnosis of the disease. However, complicated hydatid cysts can prove to be a diagnostic challenge at times due to their atypical imaging features. Radiography is the initial imaging modality. Computed tomography can provide a specific diagnosis in complicated cases. Ultrasound is particularly useful in peripheral lung lesions. The role of magnetic resonance imaging largely remains unexplored. PMID:27358685

    Radicular cysts are inflammatory jaw cysts confined to the apices of teeth with infected and necrotic pulp. They arise from the epithelial residues in the periodontal ligament as a result of inflammation, following the death of pulp. The treatment of such lesions vary with regard to their sizes; the small cystic lesions heal after an endodontic therapy, but larger lesions, may require additional treatment. Apical surgery for radicular cysts generally involves apical root resection and sealing with endodontic material. This case report, describes the treatment of a cyst related to the maxillary central and lateral incisors using platelet rich fibrin along with synthetic nanocrystalline hydroxyapatite granules for the regeneration of lost tissues. A follow-up evaluation at 6 months and 1-year revealed a significant radiographic bone fill with satisfactory healing at the surgical site. PMID:27538563

    Many chrysophyte algae produce morphologically distinctive, siliceous, microscopic cysts during a resting stage of their life cycles; these cysts are often preserved in sediments. Scanning electron microscopy and Nomarski optics permit much more detailed observation of these cysts than was heretofore possible. Many cyst types are found only in specific habitats, such as montane lakes, wet meadows, ephemeral ponds, and Sphagnum bogs. In the samples studied, cysts seem to be most common in fluctuating fresh-water habitats of low to moderate pH and some winter freezing. Chrysophyte cysts have the potential to be a useful tool for modern environmental assessments and paleoecological studies of Cenozoic fresh-water lacustrine deposits. -from Authors

An ultrasound scan of the abdomen revealed a complex cyst in the right iliac fossa and a subsequent CT scan revealed a 7.5 cm retroperitoneal cystic lesion below the lower pole of the right kidney. The patient also had MRI of the kidneys, which confirmed the finding. The image showed the cyst was not attached to the kidneys and was clearly separate. She underwent a laparoscopic excision of the cyst. Histopathology revealed a cyst lined by a single layer of mucinous epithelium of endocervical type with foci of calcification and hyalinisation on the wall. The cyst was thought to be a benign cyst of Mullerian origin.

    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

    Ultrasonographic examination of the kidneys of 111 patients on long term maintenance hemodialysis was performed. None of the patients had genuine polycystic kidney disease. In many patients acquired cysts were found. Frequency and volume of these cysts were the same on the right and left side. There was no correlation between the age of the patients and the number of cysts. There were no differences concerning sex and type of primary renal disease. There was a significant positive correlation between time on maintenance hemodialysis and number of cysts but no correlation between number of cysts and hemoglobin concentration. This is in contrast to data in the literature. Clinical relevance of acquired kidney cysts in dialysis patients concerns hematuria, retroperitoneal bleeding, kidney stone formation, septicemia and malignancy.

Two cases were treated in our department with hydatid cyst disease located in the retroperitoneum; one of the cysts was in the minor pelvis and the other was on the left psoas muscle. Diagnosis was confirmed with blood tests, and radiological examinations. The cyst wall was excised partially and was oversewn. Following the operation both of the patients were given albendasole tablets for 10 weeks with blood count and liver enzyme monitorization. Hydatic cysts located in retroperitoneum were treated successfully. Especially in the endemic areas hydatid cyst should be remembered when evaluating cystic masses in the retroperitoneum. It can be treated successfully with surgery.

    Retroperitoneal bronchogenic cyst is detected extremely rarely and often masquerades as other diseases. Here, we report 2 cases of retroperitoneal bronchogenic cyst mimicking pancreatic mucinous tumor. Histologically, both cysts were composed of ciliated respiratory-like epithelium with abundant mucin content, smooth muscle bundles and mature cartilage, compatible with the diagnosis of retroperitoneal bronchogenic cyst. In addition to these 2 cases, another 42 retroperitoneal bronchogenic cysts reported in the English literature were collected for review and analysis. Twelve (28%) were located over the peripancreatic area. Just over half (51%) of them were asymptomatic. No accurate preoperative diagnosis could be made for any of the lesions. About a third (33.3%) of the peripancreatic retroperitoneal bronchogenic cysts masqueraded as pancreatic cystic lesions.

    A 46-year-old woman presented with a 1-year history of progressive left-arm numbness. A cyst below the left hemidiaphragm was discovered incidentally when a CT scan was performed to examine the thymus for a suspected tumor. A thymic mass was found. MRI indicated that the cyst contained proteinaceous fluid. The thymoma was approached through a median sternotomy and resected, but the cyst was found to be infradiaphragmatic. A separate, left paraspinal incision was made to access the retroperitoneum, and the cyst was resected. Histologic examination showed that the cyst was bronchogenic in origin. Retroperitoneal bronchogenic cysts are very rare, and only four cases have been reported in the English-language literature.

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

    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.

    The results of surgical treatment of 29 children with cysts, and 10--with cyst-like formations of the abdominal cavity and retroperitoneal space are described. In majority of the patients, a cyst at the terminal stage was revealed. In presence of complications, they were operated on with tentative diagnosis of acute appendicitis, or ileus. The operation consisted of cyst enucleation, its elimination with resection, or removal of the organ, creation of cystodigestive anastomosis. Postoperative lethality was 12.8%.

    Mesenteric cysts are rare abdominal tumors. About 60% of these cysts occurs before 5 years of age and can be located anywhere in the gastrointestinal tract, but are most often found in the small bowel mesentery. The clinical presentation depends on the location and size of the cyst and many cases are asymptomatic and are diagnosed incidentally. The most common symptoms are abdominal pain, bloating, abdominal mass, nausea, vomiting, constipation, diarrhea, weight loss, fever and peritonitis. Complications include torsion, infarction, volvulus formation, perforation, infection, anemia, intracystic hemorrhage, intestinal obstruction and obstructive uropathy. They are typically treated by simple excision, marsupialization or segmental bowel resection and have excellent long-term prognosis.

    The incidence of epidermoid tumors is between 1% and 2% of all intracranial tumors. The usual locations of epidermoid tumor are the parasellar region and cerebellopontine angle, and it is less commonly located in sylvian fissure, suprasellar region, cerebral and cerebellar hemispheres, and lateral and fourth ventricles. Epidermoid cysts located in the posterior fossa usually arise in the lateral subarachnoid cisterns, and those located in the brain stem are rare. These epidermoids contain cheesy and flaky white soft putty like contents. Epidermoid cysts are very slow growing tumors having a similar growth pattern of the epidermal cells of the skin and develop from remnants of epidermal elements during closure of the neural groove and disjunction of the surface ectoderm with neural ectoderm between the third and fifth weeks of embryonic life. We are presenting an interesting case of intrinsic brainstem epidermoid cyst containing milky white liquefied material with flakes in a 5-year-old girl. Diffusion-weighted imaging is definitive for the diagnosis. Ideal treatment of choice is removal of cystic components with complete resection of capsule. Although radical resection will prevent recurrence, in view of very thin firmly adherent capsule to brainstem, it is not always possible to do complete resection of capsule without any neurological deficits.

    A multivesicular hydatid cyst was removed from the left kidney of a 26-year-old woman by retroperitoneal laparoscopy to avoid contamination of the abdominal cavity. A scolicidal agent (20% hypertonic saline) was injected around the kidney initially and then instilled into the cyst after the contents had been evacuated. There were no complications and no anaphylactic shock. This appears to be the first reported case of treatment of renal hydatid cyst by laparoscopy.

    Hydatid cyst is a significant health problem in endemic regions. Although progress has been made in medical treatment and interventional radiology techniques, surgery is currently the treatment of choice. The hydatid cysts are known to occur at several unusual sites in the body. With increasing experience in laparoscopy and retroperitoneoscopy, attempts have been made to offer the advantages of minimal access procedures to hydatid disease patients. We present a case report of such a patient whose retroperitoneal hydatid cyst was removed endoscopically.

These lymphatic cysts, a histological subtype of lymphangiomata, are clearly visible as collections with clear fluid-type density surrounding both kidneys. The retroperitoneal localization of this rarity has been reported in the radiological literature, whereas, to our knowledge, the radiological demonstration of the perirenal localization has not. CT provides a unique method for direct radiological visualization of the cyst.

    Esophageal duplication cyst is a rare congenital anomaly resulting from a foregut budding error during the fourth to sixth week of embryonic development. Cervical esophageal duplication cysts are very rare and may cause respiratory distress in infancy. A full-term newborn girl who was born by normal delivery was transferred to our hospital because of swelling of the right anterior neck since birth. Cervical ultrasonography showed a 40 × 24 × 33 mm simple cyst on the right neck. Tracheal intubation was required at 2 weeks of age because of worsening external compression of the trachea. Fine-needle aspiration cytology revealed the existence of ciliated epithelium. At 1 month of age, exploration was performed through a transverse neck incision. The cyst had a layer of muscle connected to the lateral wall of the esophagus. Histopathological diagnosis was a cervical esophageal duplication cyst. We describe the clinical features of infantile cervical esophageal duplication cysts based on our experience of this rare disease in a neonate, along with a review of 19 cases previously reported in literature.

    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. We document a case of a 47-year-old woman with a nasoalveolar cyst.

    Congenital laryngeal cysts are a rare cause of stridor in the neonate. Nevertheless, delayed diagnosis and treatment can cause life-threatening airway obstruction. Even though the diagnosis is easily made by careful inspection, treatment results often in recurrence. These facts are illustrated by a case of a baby with a saccular cyst. Immediately after diagnosis and 5 days later the cyst was de-roofed using a CO2 laser via an endolaryngeal approach. Because of a second recurrence an excision of the cyst was performed via a lateral cervical approach. PMID:12836468

    Introduction Progress in the development of surgical techniques has led to the growing use of video-assisted thoracoscopic surgery (VATS) techniques in mediastinal cyst treatment. Aim To present our experience of treating mediastinal cysts with the minimally invasive technique. Material and methods Fifty patients with mediastinal cysts were treated from 2001 to 2011. There were 32 women and 18 men. The age of the patients ranged from 17 to 72, the mean age being 42 years. All patients underwent basic preoperative diagnostic tests of the chest: X-ray, computed tomography (CT), bronchoscopy and spirometry; 4 patients underwent endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) and 3 fine needle aspiration biopsy (FNAB) of the described lesions. Results The VATS was performed in each case. Conversion was carried out due to superior mediastinal location in 10 cases and pleural adhesions in 3 cases. The partial resection of a cyst was performed in 3 patients. One patient was treated conservatively due to heart failure. In that patient the transthoracic needle aspiration of a cyst under ultrasound guidance using alcoholisation with 76% ethanol with a good effect was performed twice. Cyst recurrence was observed in 1 case. Conclusions The surgical access depends on the location of a cyst. The VATS resection of a superior mediastinal cyst is not always feasible. Surgery of mediastinal cysts is both diagnostic and curative. PMID:25337163

    Dermoid cyst of the parotid gland is a rare clinical entity. Definitive clinical diagnosis is often difficult to determine preoperatively because of the lack of pathognomonic features. The most frequent location of a parotid dermoid cyst is a triangular area lying above the pinna. Imaging studies do not definitely diagnose a parotid dermoid cyst. Although parotid dermoid cyst is (generally) well-encapsulated, complete removal of the cyst wall is not sufficient to cure it, so it is mandatory to perform careful excision of the cyst by parotidectomy, in terms of preserving facial nerve integrity. Histopathology of the parotid gland tumor removed by parotidectomy makes a diagnosis of certainty, by revealing a cyst wall with keratinization of the squamous epithelium and the presence of skin annexes (hair follicles, sweat glands, sebaceous glands). We present a rare case of parotid dermoid cyst in a 21-year-old male patient with symptoms and imaging rather suggestive of arch I branchial cyst and a brief review of data in the medical literature of the last 20 years.

    Echinococcosis is endemic in various regions of Turkey. Cardiac involvement in echinococcosis is rare, and lone cardiac hydatid cysts are even more unusual. Because cardiac hydatid disease can be fatal, even asymptomatic patients are optimally referred for surgical treatment. We present a rare case of a lone, primary, mobile hydatid cyst in the left atrium of a 62-year-old woman. The cyst caused dyspnea from left ventricular inflow obstruction. In addition to reporting the patient's fatal case, we discuss cardiac hydatid cysts in terms of the scant medical literature. PMID:27303247

    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

    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). PMID:27026996

    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

    Abstract Introduction: Fast-growing congenital hepatic cysts with intracystic hemorrhage are rare in clinical practice. Additionally, the clinical manifestations of and laboratory and imaging findings for this condition are often nonspecific and are particularly difficult to differentiate from those of hepatobiliary cystadenoma and cystadenocarcinoma, thus posing great challenges for diagnosis and treatment. The 2 case reports presented here aim to analyze the diagnosis and treatment of 2 rare cases of congenital hepatic cysts with intracystic hemorrhage in the Chinese Han population to provide an important reference for the clinical diagnosis and treatment of this condition. Diagnoses: These 2 case reports present 2 rare cases of congenital hepatic cysts with intracystic hemorrhage. Case 1 involved a 31-year-old patient with a very large, fast-growing hepatic cyst with intracystic hemorrhage and elevated carbohydrate antigen 199. Case 2 involved a patient with intense, paroxysmal right upper abdominal pain; computed tomography suggested a hepatic cyst with intracystic hemorrhage and possibly hepatobiliary cystadenoma. Outcomes: Both patients underwent liver resection. Postoperative follow-up showed that for both patients, the symptoms improved, the laboratory findings returned to normal levels, and the surgical outcomes were satisfactory. Conclusion: Liver resection is an ideal treatment for patients with congenital hepatic cysts with intracystic hemorrhage, and especially those with fast-growing, symptomatic hepatic cysts or hepatic cysts that are difficult to differentiate from hepatobiliary cystadenoma and cystadenocarcinoma.

Computed tomography revealed a retroperitoneal cystic mass attached to the ascending colon. The resected cyst was unilocular and filled with milky white mucus and hemorrhagic debris. Histologically, most of the cyst wall was of well-differentiated papillary adenocarcinoma with no cyst wall invasion. Other small areas of the cyst were lined with variably atypical dysplastic/metaplastic cuboidal to pseudostratified columnar epithelium. The cyst wall was mostly hyalinized, but there was apparent thickened subepithelial basement membrane, elastosis, and a single layer of smooth muscle that suggested bronchial wall structures. A mucin staining study with O-acylated sialic acid, which is used for the demonstration of gastrointestinal, cholecystic and uterine cervical mucins, was negative for the mucin-producing epithelial cells of the cyst. Thus, to our knowledge, this is the first reported case of adenocarcinoma arising in a retroperitoneal bronchogenic cyst.

  5. Germination of cysts in acetabularia mediterranea.

    Techniques for the growth of uniformly reacting populations of cysts of Acetabularia mediterranea and for quantitative measurement of cyst germination have been developed. Cysts of A. mediterranea can be induced to germinated by exposure to the atmosphere. Germination rates are very low in young cysts. They increased during exposure to total darkness. This "maturation of cysts" is found to be completed after a period of 12-15 weeks. Germination rates of cysts that have passed the maturation period exceed 90 percent in continuous white light and 80 percent in darkness. Cysts germinate in less than two days in darkness and less than four days in light. The influence of temperature at a range of 15 degrees C to 25 degrees C on germination kinetics is studied in light and darkness. Germination is accelerated with increasing temperature up to 21 degrees C. At higher temperature germination is delayed in light but the time of germination remains constant in darknesss. Rates of germination are not altered by the influence of temperature in light while in darkness there is a dramatic decrease at temperatures higher than 21 degrees C. From these findings it is concluded that cyst germinationA. mediteranea does not need any light but is influenced by light dependent systems. The influence of light is strongest at elevated temperatures.

  6. Bilateral follicular cysts in a water buffalo.

    The present short communication puts on record a case of bilateral, multiple follicular cysts in a water buffalo along with a detailed description of its ovarian biometry and follicular fluid composition. The ovarian weight and biometrical parameters were much higher than in normal cycling buffaloes. A total of three follicular cysts were observed, two on the right ovary and one on the left ovary, measuring 4.9, 3.0 and 2.6 cm yielding 21, 9 and 5 ml of follicular fluid, respectively. The cystic fluid was deep yellow in colour with a viscous consistency. The follicular fluid concentrations of glucose, total protein, cholesterol, acid phosphatase, calcium, phosphorus and progesterone in all the cysts were within the range reported previously in normal buffalo follicular fluid; however, the alkaline phosphatase concentration in cyst 1 and total bilirubin concentration in cysts 1 and 2 were higher than the values in normal follicular fluid. In contrast, the levels of urea nitrogen in cysts 1 and 3, and oestradiol in cyst 3 were lower than the normal values. All the three follicles had an oestradiol to progesterone ratio less than 1. The results of our study suggest that follicular cysts in buffalo are oestrogenically inactive and have an altered concentration of certain biochemical and hormonal constituents.

    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

    We report the case of a pedunculated cystic mass on the aortic valve discovered in a patient presenting for a routine echocardiogram. The highly mobile nature of the mass warranted prompt surgical removal to prevent cardioembolic complications. The mass was preoperatively thought to be a papillary fibroelastoma. However, the patient's history, mass morphology, and histopathology pointed toward a simple degenerative cyst--previously unreported on the aortic valve. This report describes this rare finding, discusses relevant differential diagnoses, and underscores the importance of surgical intervention in such cases. PMID:26522574

    The authors report the results of studying the complications of iliac lymphadenectomy--lymphocysts developed after radical operations in 16 of 415 operated patients with cancer of the uterus. The method of indirect radioisotope lymphography may be considered to be the most simple method of detecting lymphatic cysts. Small size lymphocysts require no special surgical intervention. Extensive incapsulated lymph accumulation renders mandatory the incision and drainage of the lymphocyst in the iliac region at the site of the involvement. The most rational prophylactic measures against lymphocysts seem to be the provision for active lymph outflow by vacuum drainage.

    Nine girls presenting under the age of 7 years with unsustained sexual precocity are described. Large ovarian cysts were detected by ultrasound in three and laparotomy in one. In two girls the symptoms resolved after surgical removal of the cyst; the other seven had spontaneous remission of symptoms, but in two of these transient breast development and bleeding recurred: further ovarian cyst formation was found in one of these patients. Endocrine studies performed before resolution of the cysts showed raised plasma oestradiol concentrations (64 to 440 pmol/l) in three girls and no appreciable rise in plasma luteinising hormone after gonadotrophin releasing hormone stimulation in two. We conclude that ovarian cyst formation with spontaneous resolution may cause transient sexual precocity in girls, and that ultrasound examination is an effective means of diagnosing and following these patients.

    19 children were diagnosed with abdominal cysts of different origin in the Surgical Unit of the Department of Pediatrics, Medical University of Pécs, Hungary between 2010 and 2013. The authors discuss the details of representative cases of a parovarial cyst, an intestinal duplication, and an omental cyst with emphasis on the clinical symptoms, diagnostic tools, and surgical interventions. The authors conclude that abdominal cysts often cause mild symptoms only, and they are discovered accidentally by ultrasound imaging performed for other reasons. In some cases, the cyst can cause severe complaints or even acute abdomen requiring emergency surgery. Laporoscopy may be a valuable method both in diagnosis and surgical therapy. Abdominal CT or MRI are not required in the majority of the patients.

    Spinal intramedullary epidermoid cyst is a rare condition. Recurrent epidermoid cyst in the spine cord is known to occur. The authors describe a case of recurrent conus medullaris epidermoid cyst in a 24-year-old female. She initially presented at 7 years of age with bladder disturbance in the form of diurnal enuresis and recurrent urinary tract infection. MRI lumbar spine revealed a 4 cm conus medullaris epidermoid cyst. Since the initial presentation, the cyst had recurred seven times in the same location and she underwent surgical intervention in the form of exploration and debulking. This benign condition, owing to its anatomical location, has posed a surgical and overall management challenge. This occurrence is better managed in a tertiary-care centre requiring multi-disciplinary treatment approach.

    Paratracheal air cysts are a rare entity in which cystic formation occurs adjacent to the trachea. Most patients with paratracheal air cysts are asymptomatic, and the cysts are detected incidentally on chest radiograph or computed tomography (CT) scan. Most symptomatic patients complain of pulmonary symptoms or repeated respiratory infection. Rarely, the air cysts can lead to paralysis of the recurrent laryngeal nerve as a result of direct compression. We report a case of a 59-year-old male patient who presented with voice change, and the cause was identified as paratracheal air cysts on a chest CT scan. Surgical resection via video-assisted mediastinoscopy was performed, and the voice recovered immediately after the operation. PMID:27525245

    Hydatid cyst develops in retroperitoneal space without accompanied lesion in other organs is defined as primary retroperitoneal hydatid cyst. It is extremely rare though hydatid cyst may affect every organ in human body. A 15 years old boy presented with a giant retroperitoneal cyst and hydatid cyst was suspected. Thorough examination did not revealed lesions in liver, lung, kidney or other organs. The diagnosis was confirmed through laparotomy. The diagnosis is difficult, but the possibility should be considered before operation to prevent spillage or fatal anaphylactic shock. Living in an endemic area, ultrasonography, CT or serology test is helpful in the diagnosis of this disease. Total cystectomy is the ideal surgery, if not possible or at high risk, partial pericystectomy is acceptable.

    Bronchogenic cyst is a benign lesion which is commonly seen in the posterior mediastinum. Diaphragmatic origin in retroperitoneum is an unusual location for a bronchogenic cyst. Cross-sectional imaging modalities describe the origin and content of the cyst evidently. Magnetic resonance (MR) images of a 42-year-old male patient who attended ER with back pain revealed a huge retroperitoneal complicated bronchogenic cyst arising from the diaphragm and surrounding the abdominal aorta anteriorly. Bronchogenic cysts in the retroperitoneum rarely originate from the diaphragm and should be kept in mind in the differential diagnoses of abdominal cystic lesions. MR imaging (MRI) is superior to other imaging techniques such as computerized tomography (CT) in detecting the origin and content of these cystic lesions.

    Many of the prostatic cysts are asymptomatic and only 5% are symptomatic (Hamper et al., 1990; Higashi et al., 1990). These symptoms include pelvic pain, hematospermia, infertility, voiding dysfunction, prostatitis-like syndrome, and painful ejaculation. Treatment of prostatic cysts includes TRUSG guided drainage, endoscopic transurethral resection, and in some cases even open surgery. In the literature, endoscopic interventions use marsupialization of the midline prostatic cyst with transurethral resection (TUR) or transurethral incision with endoscopic urethrotomy (Dik et al., 1996; Terris, 1995). Holmium: YAG laser was employed for the marsupialization of the cyst wall in midline prostatic cyst treatment for the first time in the present study. Symptoms, treatment, and follow-up are presented in this paper. PMID:26101688

    2014-03-01

    A mesenteric cyst is defined as a cyst that is located in the mesentery of the gastrointestinal tract and may extend from the base of the mesentery into the retroperitoneum. It is often asymptomatic and therefore it is usually found as an incidental finding. Preoperative diagnosis may be possible with computed tomography and magnetic resonance imaging. However, the correct diagnosis can only be made with histology. The first-choice therapy is the complete removal of the cyst, which must be accurately planned according to the anatomy of the lesion, its dimensions and its relationships with major abdominal structures. We present two clinical cases: the one of a 30-year-old man with a mesenteric cyst that was removed by laparoscopy and the other of a 61-year-old woman who underwent open excision of a huge retroperitoneal cyst.

    A rare case of retroperitoneal bronchogenic cyst is presented. A 50-year-old man was referred to our hospital for an investigation of a retroperitoneal mass. Computed tomography and magnetic resonance imaging confirmed a retroperitoneal mass, about 4 cm in diameter, adjacent to the left kidney and spleen. On the basis of these imaging modalities, a definitive diagnosis of this mass could not be made. So, resection of the mass was performed. The removed mass was an unilocular cyst and filled with mucinous fluid. Histopathologically, the cyst wall was composed of a fibrovascular connective tissue containing mucus-secreting glands and cartilages and was lined by ciliated pseudostratified columnar epitherium. Thus, a diagnosis of bronchogenic cyst was made. Bronchogenic cysts are rare congenital anomalies of the primitive foregut and usually develop in the mediastinum and lung.

    Dentigerous cyst is a developmental odontogenic cyst, which apparently develops by accumulation of fluid between the reduced enamel epithelium and the tooth crown of an unerupted tooth. Management of dentigerous cyst in primary dentition needs special consideration regarding the preservation of the developing permanent tooth buds. A case of dentigerous cyst is reported in primary dentition of a 7-year-old female patient and its management. By extracting the infected primary teeth, opening the cyst and ensuring continuous drainage, it is possible to achieve spontaneous eruption of the involved permanent teeth into the dental arch even if they are badly dislocated. Simultaneous with the eruption of the permanent teeth, ossification of the bony defect can take place. The reparatory process is completed in one to two years, during this time the patient has been given a space-maintainer.

    Objectives: To review cases of ovarian cysts managed at a University Hospital, and to identify the factors necessitating the use of laparotomy over laparoscopy. Methods: We carried out a retrospective chart review of all cases of ovarian cysts diagnosed and managed at the Department of Obstetrics & Gynecology, King Abdulaziz University Hospital, Jeddah, Saudi Arabia between January 2010 and August 2014. All data collected from medical record charts, patents details, clinical presentations, ovarian cysts description, and pathology type were recorded, and management by laparoscopy or laparotomy was identified. Ethical approval was obtained from ethical hospital committee. Results: There were 244 cases of ovarian cysts during the study period. The age ranged from 3 months to 77 years of age. The parity from 0-6. The height range from 37-180 cm. The weight range from 3-161 kg, and calculated body mass index ranged from 12-47. Out of 244 patients diagnosed, 165 were married (67.4%). Of those, only 16 patients were pregnant (6.6%). The most common presentation was abdominal pain in 142 patients (58.2%). Only 79.9% were ovarian cysts, and 17.5% were either para-ovarian or retroperitoneal. The right ovaries were affected in 63.1%, and only 18.9% were bilateral. The types of ovarian cysts included functional cysts 33.2%, benign cyst-adenoma 19.3%, and dermoid cysts 12.3%. Conclusion: Factors associated with laparotomy management rather than laparoscopy included older age >35, single, pregnant, or patients presenting with abdominal pain, and more than one cyst.

    Benign renal lesions, apart from simple cysts, are rarely sampled by fine-needle aspiration biopsy (FNAB) and are potential diagnostic pitfalls. A complex renal mass in a 33-yr-old pregnant woman, presenting in the second trimester with haematuria, was aspirated twice, a week apart, under ultrasound guidance. The second FNAB yielded predominantly mesenchymal elements thought to represent an angiomyolipoma, but the mass was identified as a multilocular renal cyst (MLRC) on the nephrectomy specimen. Differential diagnoses of angiomyolipoma, MLRC, and renal cell carcinoma (RCC) are compared and discussed in relation to patient management.

    2016-01-01

    Cystic echinococcosis (CE) is a widely endemic helminthic disease caused by infection with metacestodes (larval stage) of the Echinococcus granulosus tapeworm. E. granulosus are common parasites in certain parts of the world, and are present on every continent with the exception of Antarctica. As a result, a large number of people are affected by CE. The increased emigration of populations from endemic areas where prevalence rates are as high as 5–10% and the relatively quiescent clinical course of CE pose challenges for accurate and timely diagnoses. Upon infection with CE, cyst formation mainly occurs in the liver (70%). Diagnosis involves serum serologic testing for antibodies against hydatid antigens, but preferably with imaging by ultrasound or CT/MRI. Treatment methods include chemotherapy with benzimidazole carbamates and/or surgical approaches, including percutaneous aspiration injection and reaspiration. The success of these methods is influenced by the stage and location of hepatic cysts. However, CE can be clinically silent, and has a high risk for recurrence. It is important to consider the echinococcal parasite in the differential diagnosis of liver cystic lesions, especially in patients of foreign origin, and to perform appropriate long-term follow-ups. The aim of this review is to highlight the epidemiology, natural history, diagnostic methods, and treatment of liver disease caused by E. granulosus. PMID:27047771

    OBJECT There is currently no consensus on the safety of sports participation for patients with an intracranial arachnoid cyst (AC). The authors' goal was to define the risk of sports participation for children with this imaging finding. METHODS A survey was prospectively administered to 185 patients with ACs during a 46-month period at a single institution. Cyst size and location, treatment, sports participation, and any injuries were recorded. Eighty patients completed at least 1 subsequent survey following their initial entry into the registry, and these patients were included in a prospective registry with a mean prospective follow-up interval of 15.9 ± 8.8 months. RESULTS A total 112 patients with ACs participated in 261 sports for a cumulative duration of 4410 months or 1470 seasons. Of these, 94 patients participated in 190 contact sports for a cumulative duration of 2818 months or 939 seasons. There were no serious or catastrophic neurological injuries. Two patients presented with symptomatic subdural hygromas following minor sports injuries. In the prospective cohort, there were no neurological injuries CONCLUSIONS Permanent or catastrophic neurological injuries are very unusual in AC patients who participate in athletic activities. In most cases, sports participation by these patients is safe.

    2015-01-01

    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.

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

    PubMed Central

    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

    Purpose To detect predominant bacteria associated with radicular cysts and discuss in light of the literature. Material and methods Clinical materials were obtained from 35 radicular cysts by aspiration. Cultures were made from clinical materials by modern laboratory techniques, they underwent microbiologic analysis. Results The following are microorganisms isolated from cultures: Streptococcus milleri Group (SMG) (23.8%) [Streptococcus constellatus (19.1%) and Streptococcus anginosus (4.7%)], Streptococcus sanguis (14.3%), Streptococcus mitis (4.7%), Streptococcus cremoris (4.7%), Peptostreptococcus pevotii (4.7%), Prevotella buccae (4.7%), Prevotella intermedia (4.7%), Actinomyces meyeri (4.7%), Actinomyces viscosus (4.7%), Propionibacterium propionicum (4.7%), Bacteroides capillosus (4.7%), Staphylococcus hominis (4.7%), Rothia denticariosa (4.7%), Gemella haemolysans (4.7%), and Fusobacterium nucleatum (4.7%). Conclusions Results of this study demonstrated that radicular cysts show a great variety of anaerobic and facultative anaerobic bacterial flora. It was observed that all isolated microorganisms were the types commonly found in oral flora. Although no specific microorganism was found, Streptococcus spp. bacteria (47.5%) – especially SMG (23.8%) – were predominantly found in the microorganisms isolated. Furthermore, radicular cysts might be polymicrobial originated. Although radicular cyst is an inflammatory cyst, some radicular cyst fluids might be sterile. PMID:24011184

    2016-01-01

    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.

    Introduction. Hydatid disease (HD) is an infestation that is caused by the larval stage of Echinococcus granulosus. The liver is affected in approximately two-thirds of patients, the lungs in 25%, and other organs in a small proportion. Primary retroperitoneal hydatid cyst is extremely rare. The most common complaint is abdominal pain; however, the clinical features of HD may be generally dependent on the location of the cyst. Case Presentation. A 43-year-old female was admitted with the complaint of abdominal pain. Her physical examination was normal. Computed tomography (CT) revealed a 17 × 11 cm cystic lesion, with a thick and smooth wall that is located among the left liver lobe, diaphragm, spleen, tail of the pancreas, and transverse colon and invading the splenic hilum. Total cystectomy and splenectomy were performed. Pathological examination was reported as cyst hydatid. Discussion. Cysts in the peritoneal cavity are mainly the result of the spontaneous or traumatic rupture of concomitant hepatic cysts or surgical inoculation of a hepatic cyst. Serological tests contribute to diagnosis. In symptomatic and large hydatid peritoneal cysts, surgical resection is the only curative treatment. Total cystectomy is the gold standard. Albendazole or praziquantel is indicated for inoperable and disseminated cases. Percutaneous aspiration, injection, and reaspiration (PAIR) technique is another nonsurgical option.

    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

    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.

    Aim The goal of the paper was to evaluate the procedure of percutaneous drainage of symptomatic hepatic cysts under the transabdominal ultrasound control combined with obliteration. Material and method Within the period from 2005 to 2015, 70 patients diagnosed with a simple hepatic cyst of symptomatic nature were subject to hospitalization and treated at the 2nd General, Gastroenterological and Cancer Surgery of the Alimentary System Center and Clinics of the Medical University of Lublin. All the patients subject to evaluation were qualified to percutaneous drainage under an ultrasound control. The drainage utilized typical sets of drains with the diameter of at least 9 F, most often of pigtail type. The fluid aspirated form the cyst was dispatched for complex laboratory testing. Further, a 10% sodium chloride solution was administered to the cyst through the drain, in the volume depending on the previous size of the cyst and the patient's reaction. Results Patients reported for a re-visit within the period from 3 to 9 months following the procedure. Complete obliteration of the cyst was confirmed only in 8 patients (11%). Cyst recurrence was reported in cases when during the ultrasound evaluation, the diameter of the cyst following aspiration and obliteration enlarged to over 75% of the initial dimension. In this group, in 10 out of 12 examined (83%) there was a relapse of the previously observed ailments. Among patients, who has a cyst imaged within the period of observation, which had the diameter from 50% to 75% of the previous size, only in 6 cases (37.5%) the initial symptoms relapsed. Conclusions The utilization of a drainage and obliteration enables one to achieve the acceptable result of the therapy as well as significant decrease in the number of previously reported ailments and symptoms described.

  19. Pelvic and retroperitoneal hydatid cysts superinfected with Brucella sp. and review of infected hydatid cysts.

    PubMed

    Hydatid disease is a zoonotic infection resulting from the tissue infestation of the larval stage of the parasite Echinococcus granulosus. Hydatid cysts superinfected with pyogenic organisms have been reported previously. Brucellosis is more prevalent in people with close contact to animals and those consuming fresh milk or fresh milk products. Although these two disorders have some similar epidemiological features, we did not encounter any hydatid cyst cases superinfected with Brucella species (sp.) in a search of medical literature (Pubmed). Here, we present a case of hydatid cyst disease superinfected with Brucella and review the literature on other hydatid cyst cases superinfected with pyogenic organisms. We conclude that in regions where brucellosis and hydatid cysts are endemic, cysts may be infected with Brucella sp.

    The lack of quick, simple, and sensitive quantitative tests has impeded studies on infection patterns and treatment of Giardia spp. and Cryptosporidium spp. A quantitative direct immunofluorescence assay (FA) using a commercial FA kit was developed and evaluated. Recovery rates of the FA for Cryptosporidium oocysts in calf feces seeded with 1,000, 10,000, 100,000, and 1,000,000 oocysts per g were 14.8, 40.8, 84.2, and 78.2%, respectively. Interassay coefficients of variation were 10.6 to 47.1%. Recovery rates of the FA for Giardia cysts in feces seeded with 1,000, 10,000, and 100,000 cysts per g were 76.4, 96.9, and 89.6%, respectively. Interassay coefficients of variation were 7.4 to 22.1%. By comparison, recovery rates of Giardia cyst by sucrose gradient flotation were only 20.5, 51.2, and 42.9%, respectively. Counts of cysts-per-gram obtained by sucrose gradient flotation with samples from calves, lambs, and ewes were only 49.1 to 54.8% of those obtained by the FA. Zinc sulfate flotation detected only 36.4% of infections when there were < or = 1,000 cysts per g. The quantitative FA offers a useful technique for epidemiological and control studies of these two parasites. PMID:8263179

  1. Fiberscopic fenestration and prophylactic stenting of periaqueductal cysts: technical report on three cases.

    The authors report on three consecutive cases of periaqueductal cysts, causing non-communicating hydrocephalus, successfully treated with endoscopic fenestration and aqueductal stenting. Navigation and cyst fenestration were accomplished using a slim (1.1 mm outside diameter) optic fiberscope inserted via a pre-coronal-paramedian burr hole. Third ventriculostomy was also performed after cyst fenestration in two cases. Because of the lack of data regarding such lesions and the possible recurrence with simple fenestration, an aqueductal stent connected to a subcutaneous reservoir was placed, in all 3 cases, under direct visualization. Average duration of the procedure was less than sixty minutes and there were no intra- or perioperative complications. All patients recovered clinically and their postoperative neuroimaging assessment confirmed a decrease in size of both the ventricular system and cyst (mean follow-up: 6.8 months). The authors conclude than this minimally invasive procedure is a promising, safe and effective method to treat cerebral symptomatic periaqueductal cysts and associated non-communicating hydrocephalus.

    Introduccion. Los quistes oseos aneurismaticos espinales son lesiones osteoliticas benignas muy infrecuentes constituidas por cavidades hematicas limitadas por septos osteoconectivos y celulas gigantes tipo osteoclastos. Clinicamente se manifiestan con dolor local, sintomas neurologicos secundarios a compresion medular, asi como fracturas, deformidades e inestabilidad vertebral. Presentamos un caso de quiste oseo aneurismatico espinal dorsal con sintomatologia neurologica, tratado mediante una reseccion microquirurgica completa, sin secuelas neurologicas asociadas. Caso clinico. Mujer de 47 años, sin antecedentes traumaticos previos, valorada por presentar un cuadro de parestesias de los miembros inferiores de semanas de evolucion. El estudio radiologico de resonancia magnetica dorsal demostro la existencia de una lesion litica de bordes bien delimitados y esclerosis marginal en D4, con afectacion de los elementos posteriores vertebrales y compresion del cordon medular subyacente. La lesion fue extirpada en su totalidad, con desaparicion de la clinica sensitiva tras la intervencion. El diagnostico anatomopatologico definitivo fue quiste oseo aneurismatico espinal. Conclusion. A pesar de su baja incidencia, los quistes oseos aneurismaticos espinales deben considerarse, en el diagnostico diferencial de los tumores oseos espinales, como una posible causa de mielopatia compresiva subaguda o cronica. La reseccion tumoral completa se considera el tratamiento de eleccion, el cual con frecuencia es curativo y asocia un buen pronostico del paciente a largo plazo.

    Fifty-three cases of intracordal epidermoid cysts diagnosed, treated and followed from 1972 to 1981 are presented. In the clinical evaluation, special attention must be paid to the type of dysphonia and morphology of the vocal cords at indirect laryngoscopy. The epidermoid cyst is not easily visualized and the examiner must take into account signs like "monochorditis," slight bulging, unilateral nodule and diminished or abolished vibrations of one of the cords at stroboscopy. Microsurgical excision followed by voice therapy is the recommended treatment. The pathogenesis of these cysts is still speculative. Two theories are discussed: the traumatic theory and the dysembryoplastic theory.

    Traumatic cysts of liver are amongst the less frequently known sequelae of liver trauma. The incidence of this entity is very low. We report a case of large posttraumatic liver cyst in a young adult female, who sustained blunt abdominal trauma 2 months back. The cyst was diagnosed by CECT Abdomen and was treated by hepatic resection(left lobe). The aim of presentation of this report is to highlight the fact that blunt trauma abdomen can result in such rare presentations which can lead to hepatic resection.

    Dermoid cysts are one of the most common non-inflammatory space-occupying orbital lesions in the pediatric population. They are ectodermal cysts which may contain squamous epithelium with dermal contents such as skin, hair follicles, sebaceous glands, or sweat glands. Dermoid cyts are often innocent, however complications such as inflammation of the fistula or preseptal cellulitis are occasionally seen. We present a case of a 6-year-old girl with a glabellar dermoid cyst and describe the appropriate investigations and definitive treatment. PMID:26885559

    A total of 87 patients with 63 hydroceles and 29 epididymal cysts underwent injection sclerotherapy with polidocanol on an outpatient basis. In the hydrocele group the cure rate after 1 treatment was 67% and the overall cure rate was 87% after a median followup of 14 months. In the group treated for epididymal cyst the corresponding cure rates were 46% and 64%, respectively, with a median followup of 12 months. A low rate of complications was observed. Of 86 evaluable patients 81 (94%) were satisfied with the procedure and the treatment results. Therefore, we recommend injection sclerotherapy with polidocanol as primary treatment for hydroceles and epididymal cysts in patients older than 40 years.

    Tetracycline (Achromycin, Lederle) solution was used to produce sclerosis of 37 hydroceles and 18 epididymal cysts in patients over the age of 50 years. All but one of the epididymal cysts were sclerosed satisfactorily at 9 months; 35 hydroceles sclerosed satisfactorily, although four patients required re-treatment at 3 months. One patient required orchiectomy for an infected haematocele. Pain after instillation of tetracycline was an occasional complication which could be prevented by prophylactic spermatic cord block. Tetracycline sclerotherapy is a safe and effective alternative to surgery for hydroceles and epididymal cysts in older patients.

We report the fourth such case in an asymptomatic 4-year-old girl who initially presented for evaluation of urinary tract infection and new-onset urinary incontinence. Ultrasound, computed tomography, and magnetic resonance imaging findings were consistent with an adrenal mass. At exploration, the patient was found to have a mass in the area of the gastroesophageal junction and a normal left adrenal gland. The final pathology confirmed the diagnosis of a bronchogenic cyst. Abdominal bronchogenic cysts, although rare, should be considered in the diagnosis of a retroperitoneal mass.

    Isolated abdominal bronchogenic cysts are rare abnormalities. They are usually asymptomatic unless secondarily infected or large enough to cause compression of other vital structures. The authors report on a 20-month-old girl who had an abdominal bronchogenic cyst and presented with a history of recurrent urinary tract infections. The evaluation and treatment of this patient is presented as well as a review of the ten previously reported cases. A literature review showed only four cases in the pediatric age group. Excision is recommended to establish diagnosis and alleviate any symptoms. Abdominal bronchogenic cysts should be considered in the differential diagnosis of retroperitoneal masses.

    Cystic kidney disease includes a wide range of hereditary, developmental, and acquired conditions of the kidneys. Some of the inherited causes of cystic kidney disease include autosomal dominant polycystic kidney diseases (caused by mutations in PKD1 or PKD2), autosomal recessive polycystic kidney disease, tuberous sclerosis complex, von Hippel-Lindau disease, oral-facial-digital syndrome type I, and Hadju-Cheney syndrome. Acquired cystic kidney disease has been reported in patients receiving long-term hemodialysis or peritoneal dialysis and in children after liver transplantation. Acute kidney injury can occur in patients with neuroblastoma, usually as a result of thrombotic microangiopathy associated with bone marrow transplantation. End-stage renal disease is described in long-term survivors. However, in this case report, we provide what is to our knowledge the first description of multiple kidney cysts in long-term survivors of stage IV neuroblastoma. None of the 7 patients we describe with neuroblastoma and multiple kidney cysts had a family history of autosomal dominant polycystic kidney disease. Also, all lacked stigmata of tuberous sclerosis complex, von Hippel-Lindau disease, or Hadju-Cheney syndrome. Two patients progressed to end-stage renal disease; in addition, one of them developed an oncocytoid renal cell carcinoma. PMID:27016049

    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.

    A 71-year-old woman who had an abdominal mass was admitted to our hospital in May, 1983. Physical examination revealed the presence of a soft mass without tenderness in the right upper abdomen. The results of laboratory tests were within the normal range. An excretory urogram showed a slight lateral displacement of the upper position of the right ureter and a slight dilatation of the right pyelocalyceal system. The urogram for the left kidney and ureter was normal. Abdominal CT scan revealed a cystic homogeneous mass anterior to the right kidney, 12 X 11 cm in size. Ultrasonography showed a cystic mass corresponding to the CT scan finding. Under ultrasonographic guidance, percutaneous puncture of the cyst was performed, and 800 ml clear straw-yellow fluid containing 457 ng/ml alpha-fetoprotein was drained. A repeat CT scan 9 months later showed no evidence of fluid reaccumulation and the patient remained asymptomatic.

    Background: A rare cause of spinal cord compression is spinal arachnoid cysts. Symptoms are caused by spinal cord compression, however, asymptomatic patients have been also reported. Treatment options depend upon symptom severity and clinical course. Case Description: We report the case of a 47-year-old patient who developed an intramedullary arachnoid cyst after removal of an intradural extramedullary cyst. Conclusion: Surgery should be considered early in a symptomatic disease course. Longstanding medullary compression may reduce the possibility of neurological recovery as well as secondary complications such as intramedullary cyst formation. PMID:27512608

    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
