    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.

  3. The MRI geyser sign: acromioclavicular joint cysts in the setting of a chronic rotator cuff tear.

    2011-06-01

    We present the case of a 71-year-old man with a large acromioclavicular (AC) joint cyst successfully managed with surgical excision. AC joint cysts are soft tissue masses generally signifying underlying rotator cuff pathology. Traditionally, these cysts were identified with shoulder arthrography as a "geyser" of fluid escaping through the AC joint. Magnetic resonance imaging (MRI) is today's preferred imaging modality; we describe the MRI equivalent of the "geyser sign," signifying synovial fluid escaping through the cuff defect, across the subacromial bursa, and decompressing superiorly through a degenerated AC joint. Surgical management is preferred for symptomatic cysts. Based on a review of limited retrospective case series, recommendations for management of these lesions are as follows. Repair of the rotator cuff is preferable whenever possible. In the case of an irreparable defect, good results can be achieved through excisional AC joint arthroplasty and resection of the cyst base. Aspiration of these cysts should not be attempted, due to the high recurrence rate and potential for a draining sinus. Hemiarthroplasty also may be effective in indirectly decompressing these cysts; but given the invasive nature of this procedure, it should be reserved for patients who are also symptomatic from cuff arthropathy.

    Facet joint synovial cysts are usually associated with osteoarthritis of the adjacent facet joint and/or spondylolisthesis. In between the conservative and operative ends of the treatment spectrum lie minimally invasive techniques such as cyst rupture using epiduroscopy. In this report, we describe an 82-year-old male patient presenting with low back pain radiating to his lower left extremity and associated paresthesia. Magnetic resonance imaging of the lumbar spine revealed a synovial cyst at left L4/5 facet joint. Using epiduroscopy, the cyst was mechanically ruptured by popping it with the tip of the scope. The patient remained symptom-free at his successive visits until 12 months after the procedure, and was opened for desired follow up. PMID:26495082

  6. The first described joint-associated intraneural ganglion cyst.

    Spinner, Robert J; Wang, Huan

    2011-12-01

    This article describes the identification of the first known specimen in which an articular origin for an intraneural cyst was recognized. Prompted by early citations in the 20th century of a valuable 1904 tibial intraneural ganglion housed at St. Bartholomew's Hospital in London, we traveled there to research it. We fortuitously discovered a citation to an earlier joint-related specimen, one that had not previously been referenced correctly in subsequent publications on intraneural cysts for more than a century. The original anatomic description dating to 1884, summarized in 3 lines in a museum catalog, was attributed to T. Swinford Edwards. This cadaveric specimen affected the deep branch of the ulnar nerve and arose from a carpal joint. Additional information was provided in a Transactions in 1884. An original drawing of the specimen was published in a textbook written in 1889 by Anthony Bowlby, a former curator, both of which credited F. (Frederick) Swinford Edwards, a demonstrator in anatomy and surgery at St. Bartholomew's. Unfortunately, the specimen could not be located and is presumed lost. To establish this specimen as the first known example of a joint-related intraneural cyst, we completed a review of >400 other cases and confirmed this statement. The first observation of an articular origin for an intraneural cyst, made by 2 eminent surgeons, has not been properly acknowledged. Considered with a modern perspective, this historical case solidifies the articular (synovial) origin for these unusual intraneural cysts, a finding that has important treatment implications.

    Two patients with rheumatoid arthritis are described, who developed very large bone cysts or geodes adjacent to the knee-joint. The existence of cysts adjacent to joints involved by rheumatoid arthritis is well recognised, but the occurrence of very large cysts is unusual and may present diagnostic difficulties. Possible aetiological factors are discussed.

  8. Specific glycoforms of MUC5AC and endorepellin accurately distinguish mucinous from nonmucinous pancreatic cysts.

    Specific protein glycoforms may be uniquely informative about the pathological state of a cyst and may serve as accurate biomarkers. Here we tested that hypothesis using antibody-lectin sandwich arrays in broad screens of protein glycoforms and in targeted studies of candidate markers. We profiled 16 different glycoforms of proteins captured by 72 different antibodies in cyst fluid from mucinous and nonmucinous cysts (n = 22), and we then tested a three-marker panel in 22 addition samples and 22 blinded samples. Glycan alterations were not widespread among the proteins and were mainly confined to MUC5AC and endorepellin. Specific glycoforms of these proteins, defined by reactivity with wheat germ agglutinin and a blood group H antibody, were significantly elevated in mucinous cysts, whereas the core protein levels were not significantly elevated. A three-marker panel based on these glycoforms distinguished mucinous from nonmucinous cysts with 93% accuracy (89% sensitivity, 100% specificity) in a prevalidation sample set (n = 44) and with 91% accuracy (87% sensitivity, 100% specificity) in independent, blinded samples (n = 22). Targeted lectin measurements and mass spectrometry analyses indicated that the higher wheat germ agglutinin and blood group H reactivity was due to oligosaccharides terminating in GlcNAc or N-acetyl-lactosamine with occasional α1,2-linked fucose. The results show that MUC5AC and endorepellin glycoforms may be highly specific and sensitive biomarkers for the differentiation of mucinous from nonmucinous pancreatic cysts.

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

  10. An atypically located large subchondral cyst in an osteoarthritic hip joint: a case report

    PubMed Central

    2013-01-01

    Introduction Osteoarthritic subchondral cysts within or around the hip joint can sometimes be difficult to distinguish from primary osseous and soft tissue tumors due to their radiological appearance and uncommon location. 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.

    2014-10-01

    This case report describes a patient with an acromio-clavicular joint (ACJ) cyst, associated with a complete tear of the supraspinatus tendon, and the related arthropathy. Ultrasound was a suitable imaging modality to make the diagnosis, and rule out other pathologies. Full assessment of the rotator cuff must be carried out in the presence of ACJ cysts due to their common co-existence with large cuff tears. Cyst aspiration is not a suitable treatment, due to the high likelihood of recurrence. Optimal treatment requires management of the underlying rotator cuff tear.

  12. BAKER'S CYST

    PubMed Central

    Demange, Marco Kawamura

    2015-01-01

    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).

    Ganglion and synovial cysts of the temporomandibular joint (TMJ) are rare. Although histopathological findings differ, clinical presentation is comparable. This study adds a case report of a ganglion of the TMJ to existing literature and a review of all available case reports on ganglion and synovial cysts of the TMJ. Including our own case report, we reviewed 49 cases of ganglion and synovial cysts of the TMJ. They occurred in a female:male ratio of 3:1, at an median age of 46 years (range, 11-64 years). Patients mainly presented with preauricular swelling and pain. After imaging, the ganglion or synovial cyst was most commonly excised under general anesthesia. No recurrences were described.

    The prolapse of the intervertebral disc is most common cause of sciatica; rare causes of sciatica are pelvic fractures, pelvic tumors, piriformis syndrome, a rupture of medial head of gastronemius and sacroiliac joint dysfunction. We report the case of a 30-year-old male with a paralabral cyst of the hip joint with an acetabular labral tear causing sciatica. Our patient had an acetabular labral tear caused by a repetitive micro-trauma and external rotation injury. The diagnosis of the paralabral cyst with acetabular labral tear was based on clinical examination and histopathological examinations, and Magnetic resonance imaging findings. The patient underwent successful surgical excision of paralabral cyst and surgical repair of an acetabular labral tear. The present case reinforces the need for clinicians to be vigilant about rare causes of sciatica. PMID:25977624

    An acromioclavicular joint cyst is an uncommonly reported condition, which seems to result from a massive rotator cuff tear and degenerative osteoarthritis of the acromioclavicular joint. We present the case of an 81-year-old man affected by an acromioclavicular joint cyst, associated to a massive rotator cuff tear, proximal migration of the humeral head and osteoarthritis of the gleno-humeral joint. The mass was 7 x 2.5 cm in size and the overlying skin presented a fistula that drained clear synovial-like fluid. Plain X-ray examination of the left shoulder showed proximal migration of the humeral head migration and osteoarthritis of the gleno-humeral joint, and further MRI evaluation confirmed the clinical diagnosis of a complete rotator cuff tear and observed a large subcutaneous cyst in communication with the degenerative acromioclavicular joint. The patient underwent surgical excision of the cyst and lateral resection of the clavicle to prevent disease recurrence. To the best of our knowledge, this is the first reported case of an acromioclavicular joint cyst complicated by an aseptic fistula resulting from multiple aspirations. PMID:19918423

    2016-01-01

    We present a case of percutaneous treatment of symptomatic recurrent lumbar facet joint cyst resistant to all medical treatments including facet joint steroid injection. Percutaneous transfacet fixation was then performed at L4-L5 level with a cannulated screw using CT and fluoroscopy guidance. The procedure time was 30 min. Using the visual analog scale (VAS), pain decreased from 9.5, preoperatively, to 0 after the procedure. At 6-month follow-up, an asymptomatic cystic recurrence was observed, which further reduced at the 1-year follow-up. Pain remained stable (VAS at 0) during all follow-ups. CT- and fluoroscopy-guided percutaneous cyst rupture associated with facet screw fixation could be an alternative to surgery in patients suffering from a symptomatic recurrent lumbar facet joint cyst.

    Purpose A comprehensive review of the literature in order to analyze data about the success rate of percutaneous resolution of the lumbar facet joint cysts as a conservative management strategy. Methods A systematic search for relevant articles published during 1980 to May 2014 was performed in several electronic databases by using the specific MeSH terms and keywords. Most relevant data was captured and pooled for the meta-analysis to achieve overall effect size of treatment along with 95% confidence intervals. Results 29 studies were included in the meta-analysis. Follow-up duration as mean ± sd (range) was 16±10.2 (5 days to 5.7 years). Overall the satisfactory results (after short- or long-term follow-up) were achieved in 55.8 [49.5, 62.08] % (pooled mean and 95% CI) of the 544 patients subjected to percutaneous lumbar facet joint cyst resolution procedures. 38.67 [33.3, 43.95] % of this population underwent surgery subsequently to achieve durable relief. There existed no linear relationship between the increasing average duration of follow-up period of individual studies and percent satisfaction from the percutaneous resolutions procedure. Conclusion Results shows that the percutaneous cyst resolution procedures have potential to be an alternative to surgical interventions but identification of suitable subjects requires further research.

    2015-04-01

    An arthroscopically assisted technique for the treatment of acute acromioclavicular joint dislocations is presented. This pathology-based procedure aims to achieve anatomic healing of both the acromioclavicular ligament complex (ACLC) and the coracoclavicular ligaments. First, the acromioclavicular joint is reduced anatomically under macroscopic and radiologic control and temporarily transfixed with a K-wire. A single-channel technique using 2 suture tapes provides secure coracoclavicular stabilization. The key step of the procedure consists of the anatomic repair of the ACLC ("AC-Reco"). Basically, we have observed 4 patterns of injury: clavicular-sided, acromial-sided, oblique, and midportion tears. Direct and/or transosseous ACLC repair is performed accordingly. Then, an X-configured acromioclavicular suture tape cerclage ("AC-Bridge") is applied under arthroscopic assistance to limit horizontal clavicular translation to a physiological extent. The AC-Bridge follows the principle of internal bracing and protects healing of the ACLC repair. The AC-Bridge is tightened on top of the repair, creating an additional suture-bridge effect and promoting anatomic ACLC healing. We refer to this combined technique of anatomic ACLC repair and protective internal bracing as the "AC-RecoBridge." A detailed stepwise description of the surgical technique, including indications, technical pearls and pitfalls, and potential complications, is given.

    1977-05-01

    A comprehensive study of femoral heads of patients and cadavers with osteoarthritis, rheumatoid arthritis, osteonecrosis, and calcium pyrophosphate dihydrate deposition disease allows insight into the radiographic and pathologic appearance of subchondral radiolucencies in these disorders. The term geode, rather than cyst or pseudocyst, may be a more appropriate decription of these lesions. In osteoarthritis, goedes occur on the pressure segment of the femoral head in association with loss of articular space; in rheumatoid arthritis, they are initially noted at the chondro-osseous junction and subsequently involve the entire femoral head. In osteonecrosis, geodes appear in the necrotic segment of the femoral head. In calcium pyrophosphate deposition disease, geodes resemble those in osteoarthritis but are larger, more numerous, and more widespread.

    Digital imaging combined with picture archiving and communication system (PACS) access allows detailed image retrieval and magnification. Calcium pyrophosphate dihydrate (CPPD) crystals preferentially deposit in fibrocartilages, the cartilage of the acromioclavicular (AC) joint being one such structure. We sought to determine if examination of the AC joints on magnified PACS imaging of chest films would be useful in identifying chondrocalcinosis (CC). Retrospective radiographic readings and chart reviews involving 1,920 patients aged 50 or more who had routine outpatient chest radiographs over a 4-month period were performed. Knee radiographs were available for comparison in 489 patients. Medical records were reviewed to abstract demographics, chest film reports, and diagnoses. AC joint CC was identified in 1.1 % (21/1,920) of consecutive chest films. Patients with AC joint CC were 75 years of age versus 65.4 in those without CC (p<0.0002). Four hundred eighty-nine patients had knee films. Six of these patients had AC joint CC, and of these, five also had knee CC (83 %). Of the 483 without AC joint CC, 62 (12 %) had knee CC (p=0.002). Patients with AC joint CC were more likely to have a recorded history of CPPD crystal deposition disease than those without AC joint CC (14 versus 1 %, p=0.0017). The prevalence of AC joint CC increases with age and is associated with knee CC. A finding of AC joint CC should heighten suspicion of pseudogout or secondary osteoarthritis in appropriate clinical settings and, in a young patient, should alert the clinician to the possibility of an associated metabolic condition.

    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

    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

    The efficacy of osteochondral allografts (OCA) 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 12 months in vivo. The objectives of this study were to further analyze OCA and contralateral non-operated (Non-Op) CONTROLS from the medial femoral condyle to (1) determine the effect of OCA storage on local subchondral (ScB) and trabecular (TB) bone 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 OCA was altered compared to Non-Op, with OCA samples displaying bone cysts, ScB channels, and ScB roughening. ScB BV/TV in FROZEN OCA was lower than Non-Op and other OCA. TB BV/TV in FRESH, 4°C/14d, and 4°C/28d OCA did not vary compared to Non-Op, but BS/TV was lower. (2) OCA 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.

    Choledochal cyst is a rare disease with a considerably higher incidence found in the Asian population. 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

    We report the case of a 29-year-old gentleman with shoulder impingement. An articular-sided intratendinous supraspinatus cyst was identified as the cause of his symptoms. Arthroscopic cyst debridement resulted in a good outcome at 1-year follow-up. Cysts around the shoulder are a well described pathological entity. They consist of different categories, including intraosseus cysts of the humeral head and glenoid, paralabral cysts and cysts associated with the acromioclavicular joint. Although paralabral cysts that lie intramuscularly or between the muscle bellies have frequently been reported, this is the first report of an intratendinous supraspinatus cyst with an intact rotator cuff. We describe the case, its management and the postsurgical outcome. PMID:27582975

    2016-01-01

    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

    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.

    Medial parameniscal cysts of the knee are typically 0.3 to 9 mm in diameter. Few cases of unusually large medial parameniscal cysts have been reported. We describe the treatment of a patient with osteoarthritis of the knee who presented with an extraordinarily large, ipsilateral, medial parameniscal cyst, 10 cm in diameter. We believe this to be the largest medial parameniscal cyst reported in the English literature. Based on the patient's severe tricompartmental arthritis and associated symptoms, total knee arthroplasty (TKA) was indicated with simultaneous excision of the parameniscal cyst. Perioperativley, the cyst was found to have penetrated beyond the menisco-capsular attachments that were adjacent to a degenerative posterior horn horizontal medial meniscal tear. Following excision of the cyst, the mass was measured with surgical tape to be 10x10x5 cm. After complete excision of the parameniscal cyst, TKA was performed. Histological examination confirmed a benign parameniscal synovial cyst. At 2-year follow-up, the patient was ambulating unassisted without difficulty. The wound had completely healed with no evidence of recurrence of the cyst. The patient's range of motion was 0 degrees to 110 degrees with no signs of instability. Our patient's pathology was most significant for the heretofore unseen large size of the paramensical cyst. Open excision of this giant parameniscal cyst followed by TKA was effective in treating the patient's degenerative joint disease and extraordinarily large, painful soft tissue mass.

    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.

    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

    Baker's cysts are one of the most common cystic lesions around the knee joint and mainly caused by fluid distension of the gastrocnemius-semimembranous bursa that is situated along the medial side of the popliteal fossa. Typically, a Baker's cyst extends along the intermuscular planes around the knee joint and may enlarge any direction. However, it is mostly located in the inferomedial or superficial layers of the knee joint and less commonly extends laterally or proximally. Expansion of the cyst tends to respect the intermuscular planes, and Baker's cysts along the intramuscular route have been rarely reported. Thus, we report a case of Baker's cyst with intramuscular extension into the vastus medialis muscle. PMID:23269965

    Hydatid cyst is formed from parasitic infestation by Echinococcus granulosus, and may involve several bodily organs, primarily the liver and lungs. In endemic regions, hydatid cyst should be borne in mind in cases of retroperitoneal cystic masses. Diagnosis of hydatid cyst is made from radiological findings and serological test positivity. Hydatid cyst diagnosis can be made from typical radiological imaging findings. This paper presents the imaging findings of a 56-year old male with retroperitoneal hydatid cyst.

    The authors describe the case of an intraneural ganglion cyst involving a cranial nerve (V3), which was found to have a joint connection in support of an articular origin within the cranial nerves. An inferior alveolar intraneural cyst was incidentally discovered on a plain radiograph prior to edentulation. It was resected from within the mandibular canal with no joint connection perceived at surgery. Histologically, the cyst was confirmed to be an intraneural ganglion cyst. Reinterpretation of the preoperative CT scan showed the cyst arising from the temporomandibular joint. This case is consistent with the articular (synovial) theory of intraneural ganglion cysts. An anatomical explanation and potential joint connection are provided for this case as well as several other cases of intraneural cysts in the literature, and thus unifying cranial nerve involvement with accepted concepts of intraneural ganglion cyst formation and propagation.

    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.

    Diaphragmatic lesions are usually congenital bronchogenic cysts. A patient with a known diaphragmatic cyst presented with new onset right upper quadrant pain. Repeat imaging showed enlargement of the cyst, the CA19-9 cancer marker was raised at 312 iu/ml (normal: <27 iu/ml) and positron emission tomography combined with computed tomography showed focally increased uptake in the cystic wall. In view of symptoms and risk of neoplasia, the lesion was excised. Histology showed a benign epidermoid cyst. Features falsely suggesting neoplasia have been reported previously with benign splenic cysts but not with a benign diaphragmatic epidermoid cyst.

    A foregut cyst is formed as a result of abnormal budding and pinching of the tracheobronchial tree when bronchial buds develop to form the primitive respiratory tree. Foregut cysts are clinically classified as bronchogenic, esophageal, enterogastric, or ciliated hepatic. We present a foregut cyst that occurred in the retroperitoneum and was difficult to distinguish from other retroperitoneal cystic mass lesions. Magnetic resonance imaging was useful in revealing the cyst's continuity to adjacent organs.

    We present extremely rare and interesting case of a Baker's cyst treated with hypertonic dextrose injection. A 54-year-old female patient had a Baker's cyst which was diagnosed by an ultrasonography. After the failure of the two-weekly conservative treatment, we injected hypertonic dextrose (25%) into her right knee joint for the treatment of a Baker's cyst. Two weeks after the injection, the patient reported improvement in posterior knee pain, and an US showed a resolution of the posterior knee cyst. Certainly hypertonic dextrose injection for the treatment of a Baker's cyst appears to be a reasonable treatment option. Further studies are needed in order to elucidate the efficacy of hypertonic dextrose injection in the treatment of Baker's cysts.

    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.

    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.

    1986-01-01

    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.

    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.

  4. Symptomatic intratendinous ganglion cyst of the patellar tendon.

    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.

    Synovial cysts most commonly involve the joints of the extremities. These cysts are rarely found in the spinal canal or the vertebral facet joints. However, if manifested as such, they can pose serious diagnostic and therapeutic problems due to the presentation, which most often resembles nerve root or spinal cord compression. Acute low back pain and radiculopathy are often attributed to a herniated nucleus pulposus. This paper presents a case of synovial cyst in a 62-year-old woman with a 2-year history of refractory low back pain with distal radiation. A facet joint cyst was encountered upon neuroimaging, resulting in excision of the cyst. In this report, we discuss the differential diagnosis of synovial cysts, the role of computed tomography and magnetic resonance imaging in the diagnosis, and treatment options for this uncommon entity.

    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

    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.

    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.

    Ganglion cysts usually arise from the tissues around the facet joints. It is usually associated with degenerative cahanges in facet joints. Bilateral thoracic ganglion cysts are very rare and there is no previous case that located in bilateral intervertebral foramen compressing the L1 nerve root associated with severe radiculopathy. We report a 53 years old woman who presented with bilateral groin pain and severe numbness. Magnetic resonance imaging revealed bilateral cystic mass in the intervertebral foramen between 12th thoracal and 1st lumbar vertebrae. The cystic lesions were removed after bilateral exposure of Th12-L1 foramens. The result of hystopathology confirmed the diagnosis as ganglion cyst. The ganglion cyst may compromise lumbar dorsal ganglion when it located in the intervertebral foramen. The surgeon should keep this rare entity in their mind for differential diagnosis.

    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.

    Hydatid cysts cause diseases most frequently by localizing in the liver and the lungs. Hydatid cysts with retroperitoneal localization are very rare. 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.

    Significant efforts are underway to develop new biomarkers from pancreatic cyst fluid. Previous research has made use of cyst fluid collected from surgically removed cysts, but the clinical implementation of biomarkers would use cyst fluid collected by endoscopic ultrasound-guided, fine-needle aspiration (EUS-FNA). The purpose of this study was to investigate the clinical applicability of cyst fluid research obtained using surgical specimens. Matched pairs of operating-room collected (OR) and EUS-FNA samples from 12 patients were evaluated for the levels of three previously described biomarkers, CA 19-9, CEA, and glycan levels detected by wheat germ agglutinin on MUC5AC (MUC5AC-WGA). CA 19-9 and MUC5AC-WGA correlated well between the sample types, although CEA was more variable between the sample types for certain patients. The variability was not due to the time delay between EUS-FNA and OR collection or differences in total protein concentrations but may be caused by contamination of the cyst fluid with blood proteins. The classification of each patient based on thresholds for each marker was perfectly consistent between sample types for CA 19-9 and MUC5AC-WGA and mostly consistent for CEA. Therefore, results obtained using OR-collected pancreatic cyst fluid samples should reliably transfer to the clinical setting using EUS-FNA samples.

    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.

    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.

    Introduction Arachnoid cysts (ACs) are frequently found on intracranial imaging studies but intrasellar arachnoid cysts are rarely encountered. Presentation of case We present a 49-year old patient who had headaches for 6 months and cystic sellar mass was found in his cranial imaging. We operated him by transnasal transsphenoidal route. Our intraoperative diagnosis was an arachnoid cyst and pathologic studies verified our observation. He did well postoperatively and after a 1 year follow-up he was left free from future follow-ups. Discussion As common cystic lesions occupying the sellar region can simulate ACs both clinically and radiologically, neurosurgeon can fail to include ACs in making the initial diagnosis preoperatively. Conclusion Although a rare entity, arachnoid cysts should be considered in the differential diagnosis of sellar region. PMID:27107306

    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.

    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.

    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.

    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.

Case report A 77-year old polymorbid patient presented with bilateral low back pain which worsened during the course of time and did not respond to the conservative treatment. A diagnosis of intraspinal synovial cyst was made using the magnetic resonance imaging (MRI). Percutaneous computed tomography (CT) guided injection with installation of local anesthetic together with corticosteroid and rupture of the cyst was successfully used. A month after the procedure his pain improved, the usage of analgesics diminished and his over-all quality of life improved. Conclusions Percutaneous CT guided lumbar synovial cyst treatment is safe and reliable alternative to the surgical treatment in polymorbid patients with radiculopathy who are not able to tolerate general anesthesia and operation.

    Mascard, E; Gomez-Brouchet, A; Lambot, K

    2015-02-01

    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.

    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

The possibility to confirm or to exclude the presence of the lesion, assess the structure, presence of bilateralism and joint effusion were considered. Three subjects had known juvenile arthritis, 2 hemophilia, 11 a popliteal swelling in the absence of concomitant diseases. Results In all patients it was possible to confirm (11) or to exclude (5) the presence of Baker’s cyst. The idiopathic forms (6) exhibited anechoic structure; in patients with arthritis (3) there was hypertrophic synovium; in hemophilic patients at the presentation (2) anechoic structure with layering (serum and red blood cells); in chronic hemophilia synovial hypertrophy was seen. Joint effusion was constantly present in children with hemophilia and arthritis and in 1 case of idiopathic cyst. Conclusion Baker’s cysts in children are rare. Ultrasound is able to confirm or to exclude the presence of the lesion and it is able to evaluate characteristics, bilateralism and association with joint effusion. PMID:23396996

Among the many causes of elbow pain, cysts are primarily a diagnosis that depends on advanced imaging. When an elbow ganglion or perineural cyst is symptomatic, treatment has ranged from nonoperative to surgical intervention. Our case is unique because it is the first documented ultrasound-guided aspiration and cortisone injection that successfully alleviated a patient's symptoms. The procedures and outcomes of minimally invasive ultrasound-guided aspiration and steroid injections have not been described for cysts around the elbow.

    Background: Subchondral cysts have always been taught to be one of the cardinal radiological features of knee osteoarthritis but are not well understood. We aimed to evaluate the radiological prevalence and epidemiology of subchondral cysts in patients with knee osteoarthritis to determine if they are truly a cardinal radiological feature. Methods: All patients of a single surgeon with symptoms of knee osteoarthritis were selected for this study. All patients had failed a trial of conservative therapy and were planned for total knee arthroplasty. Patients with symptoms of and documentary evidence of inflammatory arthritis, other neurological and orthopaedic problems causing functional deficits were excluded from this study. A total of 806 plain radiographs were analyzed with the aid of an atlas for the presence of narrowed joint space, osteophytes, subchondral sclerosis and subchondral cysts. The radiological prevalence of each feature was then calculated. Demographics and pre-operative measurements were compared between patients with and without radiological evidence of subchondral cysts. Results: Subchondral cysts were only present in 30.6% of the study population. Narrowed joint space was present in 99.5%, osteophytes in 98.1% and subchondral sclerosis in 88.3% of all radiographs. The differences in prevalence were statistically significant. There was a higher proportion of females in patients with radiological evidence of subchondral cysts. These patients also had a greater varus deformity preoperatively. Conclusion: With a radiological prevalence of 30.6%, subchondral cysts should not be considered a cardinal radiological feature of osteoarthritis. Subchondral cysts may be associated with the female gender and genu varum. PMID:24533038

    Arachnoid cyst (AC) is a neurological complication of autosomal dominant polycystic kidney disease (ADPKD). Although an AC can increase the risk of a subdural hematoma, the clinical presentation of bleeding into an AC associated with ADPKD is not well known. We herein report the case of a 59-year-old woman in whom the initiation of hemodialysis for renal failure led to AC bleeding. A change of anticoagulant from heparin to nafamostat mesilate allowed dialysis to continue without rebleeding. These findings suggest that hemodialysis in patients with an AC associated with ADPKD may increase the risk of bleeding. Nafamostat mesilate may be useful in such cases. PMID:27477416

  20. Neonatal ovarian cysts: therapeutic dilemma.

    PubMed Central

    1988-01-01

    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.

    To highlight the difference in symptoms, clinical features and management of an intralingual thyroglossal cyst from a classical thyroglossal cyst. 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.

    Purpose: Bronchogenic cysts are rare benign congenital anomalies, originating from the embryonic foregut ventral segment. Adrenal bronchogenic cyst is a rare form of this anomaly. One extremely rare case of bilateral adrenal multilocular bronchogenic cyst in our hospital was reported and the relevant literatures were reviewed. Significant findings: A 51-year-old man suffered from an intermittent vague headache, fatigue and hypertension history for 2 years, which were gradually worsened in a week. Imaging tests showed bilateral suprarenal mass and left renal cysts. After underwent two retroperitoneal laparoscopic adrenal gland tumor separately, they were all proved to be both the multilocular bronchogenic cyst located in bilateral adrenal gland by histopathological examination. Conclusions: This report confirms the bronchogenic cyst that can be involved bilateral joint in the adrenal gland. And we demonstrated retroperitoneoscopic surgical management is effective in the treatment of the disease. PMID:25031770

    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.

    Hydatidosis is an endemic, widely distributed anthropozoonosis, which involves the liver, lung and other organs [Int J Urol 13 (2006) 76-9]. 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.

    Experience is recorded with the diagnosis and successful surgical treatment of 5 patients with retroperitoneal and mesenterial cysts. 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.

  10. Bone cysts: unicameral and aneurysmal bone cyst.

    PubMed

    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. PMID:25579825

    A 74-year-old man was admitted with right flank pain and discomfort lasting for 2 months. CT scanning revealed a large retroperitoneal cystic mass. There were no cysts elsewhere. Serological testing revealed hydatid disease. Preoperatively he was treated by Albendazole 400 mg for 1 month and then underwent laparotomy. The entire mass was excised en bloc and intact and right hemicolectomy was simultaneously performed for excision of the adhered ascending colon. He recovered uneventfully and was discharged on the eighth day, Albendazole was given and follow-up visits were arranged for every 6 months. Total cystectomy in case of active echinococcal cysts remains the treatment of choice.

    Retroperitoneal cysts are most commonly found in relation to the small bowel but may be found in the mesentery of the colon or in the omentum. Only a few hundred cases have been reported. 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.

  13. Diagnostic accuracy of cyst fluid amphiregulin in pancreatic cysts

    2012-01-01

    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

    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.

    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.

    Arachnoid cysts (AC) are intracranial, extracerebral cysts. They can produce a wide variety of neurological symptoms, but they can also be asymptomatic or produce psychological or psychiatric symptoms. First, a short overview of the clinical manifestations of AC is given. There is an astonishing lack of literature dealing with psychological problems in children with AC. The case of a 12-year-old boy with a large left temporofrontal AC without increased intracranial pressure is presented. The psychiatric symptoms, which had begun only a few months earlier, included lack of interest, attention deficit, difficulties in contact and communication, severe outbursts of aggression and obsessive-compulsive, inhibited behavior. The main neuropsychological finding was slow and hesitant expression of thoughts despite an intelligence level in the upper normal range. The findings and course are described in detail. They are discussed as signs of an organic psychosyndrome due to the AC.

    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.

    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.

    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.

    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.

  8. Retroperitoneal, mesenteric, and omental cysts.

    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.

    Pathologic dilatation of the maxillary sinus by air is a rare condition with unclear etiology. We present a case of a 17 year old male with a maxillary air cyst diagnosed by computed tomography. The CT demonstrated air-filled expansion of the maxillary sinus beyond the normal anatomical limits with associated cortical bone thinning. The case report highlights the pathognomonic computed tomography findings of this rare entity and discusses the perplexing nomenclature, proposed etiologies and various treatment options.

    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.

    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

    An intracranial arachnoid cyst was detected in a 32-year-old, 44.6-kg, female chimpanzee at the Primate Research Institute, Kyoto University. Magnetic resonance imaging (MRI) and computed tomography (CT) were performed and the cognitive studies in which she participated were reviewed. MRI revealed that the cyst was present in the chimpanzee's right occipital convexity, and was located in close proximity to the posterior horn of the right lateral ventricle without ventriculomegaly. CT confirmed the presence of the cyst and no apparent signs indicating previous skull fractures were found. The thickness of the mandible was asymmetrical, whereas the temporomandibular joints and dentition were symmetrical. She showed no abnormalities in various cognitive studies since she was 3 years old, except a different behavioural pattern during a recent study, indicating a possible visual field defect. Detailed cognitive studies, long-term observation of her physical condition and follow-up MRI will be continued.

    Retroperitoneal cysts are rare lesions, variable from asymptomatic cases with incidental discovery to case with acute or chronic abdominal discomfort. 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.

    PubMed

    2014-01-01

    Acromioclavicular (AC) joint instability is a common source of pain and disability. The injury is most commonly a result of a direct impact to the AC joint. The AC joint is surrounded by a capsule and has an intra-articular synovium and an articular cartilage interface. An articular disc is usually present in the joint, but this varies in size and shape. The AC joint capsule is quite thin, but has considerable ligamentous support; there are four AC ligaments: superior, inferior, anterior and posterior. The coracoclavicular (CC) ligament complex consists of the conoid and trapezoid ligaments. They insert on the posteromedial and anterolateral region of the undersurface of the distal clavicle, respectively. The coracoid origin of the trapezoid covers the posterior half of the coracoid dorsum; the conoid origin is more posterior on the base of the coracoid. Several biomechanical studies showed that horizontal stability of the AC joint is mediated by the AC ligaments while vertical stability is mediated by the CC ligaments. The radiographic classification of AC joint injuries described by Rockwood includes six types: in type I injuries the AC ligaments are sprained, but the joint is intact; in type II injuries, the AC ligaments are torn, but the CC ligaments are intact; in type III injuries both the AC and the CC ligaments are torn; type IV injuries are characterized by complete dislocation with posterior displacement of the distal clavicle into or through the fascia of the trapezius; type V injuries are characterized by a greater degree of soft tissue damage; type VI injuries are inferior AC joint dislocations into a subacromial or subcoracoid position. The diagnosis of AC joint instability can be based on historical data, physical examination and imaging studies. The cross body adduction stress test has the greatest sensitivity, followed by the AC resisted extension test and the O'Brien test. Proper radiographic evaluation of the AC joint is necessary.

    Lumbar synovial cysts are an uncommon cause of back pain and radiculopathy, usually manifesting with gradual onset of symptoms, secondary to involvement of the spinal canal. Rarely, intracyst hemorrhage occurs, and may acutely present as radicular - or even spinal cord - compression syndrome. Synovial cysts are generally associated with degenerative facets, although the pathogenesis has not been entirely established. We report a case of bleeding complication in a synovial cyst at L2-L3, adjacent to the right interfacet joint, causing acute pain and radiculopathy in a patient on anticoagulation therapy who required surgical resection.

    Introduction: Synovial chondromatosis is a rare intraarticular benign condition arising from the synovial membrane of the joints, synovial sheaths or bursae around the joints. Primary synovial chondromatosis typically affects the large joints in the third to fifth decade of life, although involvement of smaller joints and presentation in younger age group is also documented. The purpose of this case report is to document this rare extra articular synovial pathology present inside the baker’s cyst which required open synovectomy and debridement to eradicate it. Case Report: A 43 yearold male presented with a two year history of pain, swelling and restriction of right knee joint. After the clinical and radiological assessment, open synovectomy, removal of cyst and thorough joint debridement procedure was performed. Histopathological study confirmed the findings of synovial chondromatosis. Conclusion: Synovial chondromatosis is a rare benign condition. Complete synovectomy offers reliable cure rate.

    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.

    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.

    The acromioclavicular (AC) complex consists of bony and ligamentous structures that stabilize the upper extremity through the scapula to the axial skeleton. The AC joint pathology in the athlete is generally caused by 1 of 3 processes: trauma (fracture, AC joint separation, or dislocation); AC joint arthrosis (posttraumatic or idiopathic); or distal clavicle osteolysis. This article presents systematically the relevant anatomy, classification, evaluation, and treatment of these disorders. Management of AC joint problems is dictated by the severity and chronicity of the injury, and the patient's needs and expectations.

    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.

    PubMed Central

    Bombaci, Hasan; Kuyumcu, Mehmet; Coskun, Tamer; Kaya, Emre

    2016-01-01

    Introduction: Meniscal cysts very often cause meniscal tears and especially when it is peripheral, some of the healthy parts of meniscus might be needlessly sacrificed. In particular conditions, extraarticular approaches might save some menisci. In the present study, we evaluated the conditions which required using the extraarticular approach in addition to the arthroscopic procedure, to maximally preserve the meniscus. Methods: Eight patients with perimeniscal cysts were evaluated retrospectively. One cyst was localized within the medial meniscus and seven in the lateral meniscus. The mean age was 36.13 (range; 19–63) years, mean follow-up time, 27.3 (range; 12–47) months. Patients were evaluated by using a Visual Analogue Score (VAS) to measure pain relief and “Lysholm score” to measure functional improvement. In all patients except one, in which the cystic cavity was connected with the joint at the periphery of the meniscus, the cyst was drained from the intraarticular opening. When the cyst was too large (three cases) and in one case where a large amount of meniscus was preserved for reasons mentioned above, additional extraarticular drainage was carried out. Results: The mean preoperative and postoperative VAS were 6 (range; 2–8) and 1.55 (range; 0–3) (p = 0.00058) and Lysholm scores were 64.75 (range; 48–86) and 93.11 (range; 80–100) (p = 0.0014), respectively. Discussion: In cysts, which have very limited or no connection with the joint on the most peripheral region of the meniscus and/or are larger than the meniscus height, extraarticular drainage of the cyst might produce unnecessary meniscal loss and function. In the extraarticular drainage, scrapping the walls of the cyst, while inspecting with an arthroscope, reduces recurrence of the cyst. PMID:27163108

    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.

    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.

We describe the case of a patient with ENWs in coexistence with an arachnoid cyst (AC). The patient was a 15-year-old boy who presented with nocturnal attacks characterized by complex motor behaviors. An MRI revealed a left temporal cyst and a SPECT Tc99 scan showed left temporal hypoperfusion and bilateral frontal hyperperfusion, more evident on the right side. During an all-night polysomnographic recording with audiovisual monitoring, dystonic posture followed by sleepwalking-like behavior was documented. The sleepwalking-like behavior was preceded by a spike discharge over the left frontocentral region with contralateral projection and secondary generalization during stage 2 sleep. Treatment with levetiracetam produced a striking remission of seizures. This supports a conservative management of an AC, considering that it may be an incidental finding. In epileptic patients, an AC may not necessarily be related to the location of the seizure focus. PMID:17694730

    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.

    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.

An MRI scan revealed an 8 cm cystic lesion in the left upper retroperitoneum, with intermediate signal on T2-weighted images, high signal on T1 weighted images, and lack of internal enhancement after gadolinium. After laparoscopic excision, the histology findings were compatible with a bronchogenic cyst, which is extremely uncommon in the retroperitoneum.

    Compression of the common peroneal nerve by synovial cysts of the tibiofibular joint is a rare disease. Two macroscopic forms may be encountered: extraneural cysts and intraneural cysts. In a review of the literature, we found only three pediatric cases of common peroneal nerve palsy due to extraneural cysts and about 60 cases reported in adults. Taking advantage of the clinical history of two children operated in our department for this disease, we describe this uncommon entity, which must be diagnosed and treated rapidly. Even in the presence of severe clinical and electrophysiological symptoms, a full clinical recovery is possible, as observed in these two children. However, follow-up is needed because recurrence is possible.

    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.

    The authors report a case of tumour of the right iliac region in a 14 years old girl, disclosed by a light traumatism, without appreciable antecedents, nor locomotor disfunction. Ultrasonography and computed tomography showed its cystic constitution. Surgically, there was a synovial cyst of the ilioinguinal area, cyst of the iliopsoas bursa, with a hip joint communication. It was resected and a partial recurrence occurred, corrected surgically three years later. A recent MRI showed the spontaneous development of a same cyst on the left side, asymptomatic at all. A non exhaustive survey of literature confirmed the iliopsoas synovial bursa is uncommonly pathologic, but a constant natural formation in man. Pathology occurs only in over sixty years old adults. This case seems to be the first pediatric case. The cyst of the psoas bursa is generally revealed by an inguinal swelling; abdominal growing is rare. Imaging with ultrasonography, computed tomography and RMI such as in this case, showed the cyst issued between the coxofemoral joint and the iliac psoas terminal tendon. It can grow in a retroperitoneal way. Pathogenic hypothesis are debated. In this bilateral case, etiology evoke an anatomic anomaly, in relation a joint communication.

    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 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

    Acute injuries of the AC joint have a limited differential diagnosis. A thorough examination and appropriate radiographs can identify nearly all problems while ruling out tumors as a causal factor. AC injury frequently occurs with other fractures, dislocations, or soft tissue injury around the shoulder. The single unifying diagnosis one searches for in medical conditions is frequently absent in musculoskeletal injury. For effective management of AC separations, the primary care physician need only distinguish type I, II, and III injuries from surgically treated type IV, V, and VI injuries. Types I, II, and III injuries should be treated with pain control and progressive rehabilitation as described previously. Patients who have types IV, V, and VI injuries should be referred to an orthopedic surgeon. Chronic injuries of the AC joint are also clearly diagnosed by appropriate physical examination and radiographs. Steroid injections can aid in the diagnosis and management of these conditions. Injury to one shoulder component predisposes to other shoulder injuries. A thorough examination will reveal these other associated abnormalities that may not be part of the presenting complaint. With practice in the examination of the shoulder and intra-articular injections, the primary care physician can effectively treat most common AC conditions. Only after conservative measures fail is it necessary to refer the patient for surgical management.

We reviewed all cases of respiratory epithelial cysts diagnosed at three institutions (two tertiary referral hospitals, one private clinic) between 1995 and 2015. 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. We present a rare case of large primary peritoneal hydatid cyst misdiagnosed as torsion of ovarian cyst that underwent Laparotomy with cyst excision and postoperative Albendazole therapy.

They can be located at any part of the posterior mediastinum adjacent to the oesophagus, but communication with that structure is rare. Approximately 60 percent of the cysts occur in infants less than one year of age, and symptoms of tracheal or oesophageal obstruction are common. The cysts usually contain clear, colorless mucoid fluid. The authors describe here a successfully treated enteric cyst with an unusual, retroperitoneal location, which presented in an adult.

    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.

    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

    Lymphoepithelial cyst (LEC) of the pancreas is an extremely rare, benign pancreatic cystic lesion that is difficult to differentiate preoperatively from other cystic pancreatic lesions. LEC may have malignant potential. Here, we describe a case of LEC of the pancreas – initially suspected to be a mucinous cyst neoplasm – in an elderly man presenting with abdominal pain, who went on to have a distal pancreatectomy and splenectomy. We also review the relevant literature and discuss implications for the diagnosis and management of this rare lesion. PMID:27403123

    The use of minimal invasive surgery in urology continue to increase. Retroperitoneoscopic approach in performing minimal invasive surgery of retroperitoneum shortens the duration of operation in comparison with transabdominal approach, with minimal risk of intraabdominal complications. We described the use of the retroperitoneoscopic approach to the upper pole of a kidney for marsupialization of a symptomatic renal cyst. The procedure was minimally traumatic, morbidity was negligible and the patient was discharged from the hospital the third day after the operation. We believe that retroperitoneoscopic management of giant symptomatic renal cysts will be applicable, together with other existing methods.

    Authors present a case of a retroperitoneal lymphoepithelial cyst, which occurs rarely in this localisation. The histological picture is reminiscent of a branchiogen cyst. 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.

    Cysts arising from hepatic bile ducts are a common extra-renal pathology associated with polycystic kidney disease in humans. As an initial step in identifying active components that could contribute to disease progression, we have investigated the protein composition of hepatic cyst fluid in an orthologous animal model of autosomal recessive polycystic kidney disease, heterozygous (BALB/c-cpk/+) mice. Proteomic analysis of cyst fluid tryptic digests using LC-MS/MS identified 303 proteins, many of which are consistent with enhanced inflammatory cell processes, cellular proliferation, and basal laminar fibrosis associated with the development of hepatic bile duct cysts. Protein identifications have been submitted to the PRIDE database (http://www.ebi.ac.uk/pride), accession number 9227.

    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.

    Acromioclavicular (AC) joint injuries are common in athletic populations and account for 40% to 50% of shoulder injuries in many contact sports, including lacrosse, hockey, rugby and football. The AC joint is stabilized by static and dynamic restraints, including the coracoclavicular (CC) ligaments. Knowledge of these supporting structures is important when identifying injury and directing treatment. Management of AC injuries should be guided by severity of injury, duration of injury and symptoms, and individual patient factors. These help determine how best to guide management, and whether patients should be treated surgically or nonsurgically. Treatment options for AC injuries continue to expand, and include arthroscopic-assisted anatomic reconstruction of the CC ligaments. The purpose of this article is to review the anatomy, diagnostic methods, and treatment options for AC joint injuries. In addition, the authors' preferred reconstruction technique and outcomes are presented.

    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.

    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.

    Chronic subdural hematoma (CSDH) is a collection of old blood and its breakdown products between the surface of the brain parenchyma and the outermost layer called the dura. The most common treatment option for primary CSDH is burr-hole trephination; however, the treatment method for recurrent CSDH is still widely debated. An arachnoid cyst (AC) is a sac filled with cerebrospinal fluid located between the brain or spinal cord and the arachnoid membrane, which is one of the three meninges covering the brain or spinal cord. Although it is rare, the cyst is associated with CSDH in juveniles, and the recurrence rate of CSDH increases in such cases. Much of the literature has supported the preventive role of middle meningeal artery (MMA) embolization in recurrent CSDH. We report a 13-year-old male patient with recurrent CSDH and AC where the early intervention of MMA embolization was proven effective in preventing the further recurrence of CSDH. PMID:27169092

    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

    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

    Arachnoid cysts (AC's) are congenital anomalies that occur within the cerebrospinal fluid (CSF) cisterns and major cerebral fissures. Suprasellar AC's comprise 5-12.5% of all the lesions. Despite being commonly reported, their etiology and pathogenesis still remain unclear. In this report, we presented an unusual case of spontaneous shrinkage of a suprasellar AC that had been incidentally diagnosed during a routine prenatal sonographic examination. To our knowledge, only three cases of spontaneous shrinkage of suprasellar AC have been reported in the literature. In detail of the manuscript, fetal and postnatal radiological images were presented and the possible mechanisms were discussed with a review of the literature. PMID:26242350

    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.

    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.

    A case of perirenal lymphatic cysts demonstrated by computed tomography is reported. 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.

    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

    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.

    ALMA Common Software (ACS) provides a software infrastructure common to all ALMA partners and consists of a documented collection of common patterns and components which implement those patterns. The heart of ACS is based on a distributed Component-Container model, with ACS Components implemented as CORBA objects in any of the supported programming languages. ACS provides common CORBA-based services such as logging, error and alarm management, configuration database and lifecycle management. Although designed for ALMA, ACS can and is being used in other control systems and distributed software projects, since it implements proven design patterns using state of the art, reliable technology. It also allows, through the use of well-known standard constructs and components, that other team members whom are not authors of ACS easily understand the architecture of software modules, making maintenance affordable even on a very large project.

    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

    Ganglion cysts are benign masses that originate from mucinous degeneration of the connective tissues and are quite rare when arising from the knee joint. Symptoms are often represented by pain, joint tenderness, effusion and occasional swelling with a palpable mass in the popliteal region of the knee. Percutaneous aspiration followed by a corticosteroid injection of a ganglion cyst has either a diagnostic or therapeutic meaning and its guidance through ultrasound allows the operator to make more accurate the procedure, ensuring the correct placement of the needle inside the lesion. We report our experience in the treatment of a voluminous ganglion cyst of the posterior cruciate ligament performed through the ultrasound guidance in a symptomatic young patient.

    Although discal cysts are a rare cause of low back pain and radiculopathy. Currently, surgical excision is usually the first-line treatment for discal cysts. However, alternative treatment methods have been suggested, as in some cases symptoms have improved with interventional therapies. A 27-year-old man presented with an acute onset of severe pain, and was found to have a discal cyst after an open discectomy. The patient underwent cyst aspiration and steroid injection through the facet joint under C-arm guidance. After the procedure, the patient's pain improved to NRS 0-1. On outpatient physical examination 1 week, and 1 and 3 months later, no abnormal neurological symptoms were present, and pain did not persist; thus, follow-up observation was terminated. When a discal cyst is diagnosed, it is more appropriate to consider interventional management instead of surgery as a first-line treatment, while planning for surgical resection if the symptoms do not improve or accompanying neurologic deficits progress.

    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

    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.

    A unique case of adenocarcinoma arising in a retroperitoneal bronchogenic cyst is presented. A 55-year-old woman presented with lower abdominal discomfort. 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.

    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.

    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

  5. Transient sexual precocity and ovarian cysts.

    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.

    Typically, rheumatoid cysts are associated with obvious joint involvement and are located in the subchondral portion of the adjacent joint. Giant pseudocysts (geodes) are uncommon and are characteristically associated with extensive joint destruction. The patient described in this report had a giant pseudocyst of the femoral neck but no joint involvement. To the best of my knowledge, this is the first report of such a manifestation of a giant pseudocyst. As such, it posed a somewhat difficult diagnostic problem.

    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.

    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

    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.

    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.

    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

    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.

    2015-01-01

    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

    A microfabricated instrument for detecting and identifying cells and other particles based on alternating current (AC) impedance measurements. The microfabricated AC impedance sensor includes two critical elements: 1) a microfluidic chip, preferably of glass substrates, having at least one microchannel therein and with electrodes patterned on both substrates, and 2) electrical circuits that connect to the electrodes on the microfluidic chip and detect signals associated with particles traveling down the microchannels. These circuits enable multiple AC impedance measurements of individual particles at high throughput rates with sufficient resolution to identify different particle and cell types as appropriate for environmental detection and clinical diagnostic applications.

    Although recent advances have been made in the treatment of acromioclavicular (AC) joint injuries, they are still challenging for shoulder surgeons. There is a consensus that type I and II injuries should be treated nonoperatively, whereas acute type IV, V, and VI injuries should be treated surgically. There is no algorithm for correctly diagnosing and treating type III injuries, but the current trend is toward nonoperative treatment except for those with persistent symptoms and functional limitations after a course of conservative management. If surgery is indicated, newer anatomic techniques of reconstructing the coracoclavicular (CC) and AC ligaments are recommended.

    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.

    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.

    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.

    Bronchogenic cyst (BC) is a rare congenital malformation of the lung. Most patients remain asymptomatic until adulthood while some are symptomatic in the first few years of life. However, symptoms in newborn period are rare. We report a case of a 3-day-old preterm baby with respiratory distress diagnosed as congenital lobar emphysema on chest X-ray. A CT scan revealed a mediastinal cyst causing obstructive lobar emphysema. The cyst was excised and pathological examination was suggestive of BC. PMID:27609589

    Isolated abdominal bronchogenic cysts are extremely rare. 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.

    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.

The clinical and therapeutic aspects are discussed for each particular localization: the splenic localization was encountered in 16 cases, the peritoneal one in 10 cases, the diaphragmatic in 6 cases. There were also 2 renal localizations, 3 retro-peritoneal ones, 3 ovarian and salpyngean localizations, 3 thyroid, 7 endo-thoracic but extra-pulmonary, 5 muscular and 6 subcutaneous localizations. Radical surgery had immediate and late results that were quite satisfactory. No deaths or recidives were noted.

    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

Computed tomography scan done previously revealed a left temporal arachnoid cyst (AC) due to which he was referred for surgery. However, magnetic resonance imaging revealed a constellation of abnormalities - all of which could be responsible for his seizures. The combination of periventricular nodular heterotopias with encepaholcele is rarely described in the literature, and more infrequently so its combination with AC and callosal dysgenesis - the Chudley-Mccullough syndrome. We describe the case and review relevant literature on this subject.

    A microfluidic switch has been demonstrated using an AC Magnetohydrodynamic (MHD) pumping mechanism in which the Lorentz force is used to pump an electrolytic solution. By integrating two AC MHD pumps into different arms of a Y-shaped fluidic circuit, flow can be switched between the two arms. This type of switch can be used to produce complex fluidic routing, which may have multiple applications in {micro}TAS.

  12. Isolation of sequences flanking Ac insertion sites by Ac casting.

    PubMed

    2013-01-01

    Localizing Ac insertions is a fundamental task in studying Ac-induced mutation and chromosomal rearrangements involving Ac elements. Researchers may sometimes be faced with the situation in which the sequence flanking one side of an Ac/Ds element is known, but the other flank is unknown. Or, a researcher may have a small sequence surrounding the Ac/Ds insertion site and needs to obtain additional flanking genomic sequences. One way to rapidly clone unknown Ac/Ds flanking sequences is via a PCR-based method termed Ac casting. This approach utilizes the somatic transposition activity of Ac during plant development, and provides an efficient means for short-range genome walking. Here we describe the principle of Ac casting, and show how it can be applied to isolate Ac macrotransposon insertion sites.

    A conjunctival cyst is a thin-walled sac or vesicle that contains fluid. This vesicle may develop either on or under the conjunctiva. It develops due to variety of causes such as infection, inflammation, retention cyst and rarely drug induced. The authors aimed to report a case of conjuctival cyst in a 34-year-old male following instillation of anti-allergic topical drugs for over period of one year. Conjuctival cyst developing due to chronic use of anti-allergic topical drugs containing preservatives is one of the complications associated with it. Presence of a preservative in an ocular medication has often been considered in damaging the epithelium. Inclusion of a preservative is equally necessary, especially in multiple-drug therapy in order to protect against dangerous organisms accidentally gaining access during instillation. Benzalkonium chloride (BAK), chlorobutanol, chlorhexidine acetate (CHA) and phenylmercuric nitrate or acetate are some commonly used preservatives in eye drops. PMID:26675748

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

    Purpose To report two cases of solitary unilateral vitreous cyst. Methods A complete ocular examination, fundus photography, B-scan ultrasound and spectral-domain optical coherence tomography were performed in both patients. Results The first patient (a 39-year-old man) presented with transient blurred vision in the right eye. The second patient (a 78-year-old man) reported transient blurred vision in the right eye when changing head position. He was referred to the Eye Hospital because of vitreomacular traction in the other eye. After examination, a diagnosis of vitreous cyst was made in both cases. Conclusions Vitreous cysts are rare clinical findings. They can occur in normal eyes or in eyes with certain ocular pathologies. When a cyst floats into the visual axis area, it can disturb visual function; therefore, patients usually report transient blurring of vision. A prompt clinical examination is necessary for differentiating this rare condition. PMID:24348410

    Epidermoid cysts are malformations that are rarely observed in the submental region. Imaging has an important role in surgical planning according to the size and location of the cyst in relation to geniohyoid and mylohyoid muscles. This article reports the case of a 15-year-old female patient complaining of submental swelling. The differential diagnosis included infection, tumor, ranula, and abnormalities during embryonic development. The lesion was surgically excised using an extra-oral approach. The histopathological examination revealed a cyst wall lined with stratified squamous epithelium with the presence of several horny scales consistent with the diagnosis of an epidermoid cyst. No recurrences were found after 1 year of follow-up. PMID:27547744

    Arachnoid cysts are very common lesions in paediatric patients, with treatment depending on their location and symptomatology. They are usually solitary cysts but may be associated with other central nervous system diseases such as tumours and congenital deformities. We describe the case of a neonate diagnosed with an arachnoid cyst of the quadrigeminal cistern treated by endoscopy. After the operation, the child's condition worsened; a CT scan revealed a midline posterior fossa tumour not visible in the preoperative neuroradiological tests. The tumour, a medulloblastoma, was partially removed. Given the child's age and the poor prognosis, oncological treatment was not undertaken. The association between medulloblastoma and arachnoid cyst is very rare, and we could find only one such case in the literature.

    Retroperitoneal cystic tumors are uncommon. More than two thirds are malignant. Benign lesions include lipomas and leiomyomas, among others. Bronchogenic cysts are congenital anomalies that result from an abnormal budding of the primitive foregut, and are most commonly found in the mediastinum. Occasionally they can be seen in the skin, subcutaneous tissue, in the pre-sternal and pericardial areas, but those located under the diaphragm are extremely rare. We report a 24 year-old female who consulted for abdominal pain. An abdominal ultrasound disclosed a retroperitoneal cystic lesion, that was confirmed with a CAT scan. The patient was operated, finding a cyst that was adhered to the pancreas. A distal pancreatectomy and cyst excision were done. The pathological examination of the lesion showed a bronchogenic cyst. The patient was discharged ten days after surgery.

Indirect hemagglutination test was positive in all cases but eosinophilia was present only in 1 (20%) case. Nephrectomy was performed to 1 patient who presented with hydaturia and had a large communicating cyst involving most of the kidney. Total cystectomy was performed in other renal cysts. Total cystectomy with wide excision of the involved muscle was performed to the retroperitoneal hydatid cyst. Patients were followed by an average of 23.8 (9-50) months with indirect hemagglutination test and USG. No evidence for recurrence was found up to date.

    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.

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

In a one-month neonate, cyst was punctured with keratome and gentle diode laser endophotocoagulation was applied to the base. A2.5-month infant presented with watering and blepharospasm since birth. Clear fluid was aspirated from the cyst with a 27-gauge needle and Ethanol 96% (ETOH) was injected into the cyst and then aspirated. It was followed by injection/aspiration of 0.3 ml of balanced salt solution thrice. Cyst wall was excised. A13-month toddler presented with 4-month history of intermittent irritation and photophobia. The cyst was aspirated with a 25-gauge needle and the cyst walls were nibbled with 20-gauge vitrectomy cutter. Excision is better than injection of sclerosing solutions. The aim is to remove the whole cyst to avoid recurrence and to prevent amblyopia. PMID:27376231

  10. In vitro function of cyst epithelium from human polycystic kidney.

    It is thought that cysts in polycystic kidneys originate from nephron segments and function in a manner similar to the segment or origin. The indirect evidence for this derives from studies of microanatomy and cyst fluid composition. Cysts with low Na+ have been classified as distal, whereas cysts with high Na+ have been classified as proximal. In order to directly determine the transport characteristics of cyst epithelium, cysts from a human polycystic kidney were studied in vitro using Ussing chamber techniques. Composition of cyst fluid was determined in parallel with these studies. Cysts with low Na+ (gradient cysts) demonstrate characteristics consistent with distal nephron origin including elevated potential difference (PD), short-circuit current (Isc), and low conductance. PD and Isc of gradient cysts were amiloride sensitive. Nongradient cysts, however, require additional characterization. At least two types of nongradient cysts were identified, one with characteristics consistent with proximal nephron origin and another apparently without function. These studies are the first direct evidence for active transport of cysts from human polycystic kidney and provide strong evidence to support the concept that cysts function in the same manner as the nephron segment of origin.

    The goal of this study was to assess the results of treatment of mucous cysts by subcutaneous excision and osteophyte resection without an associated skin procedure. From 1993 to 2013, 81 mucous cysts were operated on. In 27 cases, a nail deformity was present. Obvious osteoarthritis was present in 84% of cases. Among them, 67 patients (68 cysts) were subsequently assessed through a phone questionnaire after a mean follow-up of 6.6 years. Patients who reported a recurrence or suspected one were reassessed in consultation. Among the 68 evaluated cases, two developed an infection and one had delayed skin healing; these complications occurred on cysts with a previous fistula. In one case (1.5%), a recurrence was observed four months after excision of a subungual cyst. All nail deformities had resolved; 53 patients felt no discomfort and 65 were very satisfied or satisfied with the procedure and would undergo surgery again. The recurrence rate of 1.5% is consistent with that of other studies where the same procedure was used, without cutaneous grafting, ranging from 0 to 2%. This result is better than in studies where a graft or a flap was performed without systematic joint debridement. Our procedure is sufficient to effectively treat mucous cysts with less morbidity. Complications are rare and occur only in cysts associated with a fistula, justifying their early surgical treatment.

    Objective The objectives of this study were to investigate the relationship between the segmental localization of liver hydatid cyst by computed tomography (CT) and the presence of cystobiliary communication (CBC) and to identify the risk factors for CBC. Patients and methods One hundred and eleven of 163 patients who underwent liver hydatid surgery between January 2011 and September 2014 were included in this study and analyzed retrospectively. The size, number, stage, and segmental and lobar localization of the cysts were investigated by CT. The presence of CBC and preoperative laboratory findings were recorded from operation notes. Results CBC was more frequent in single large cysts. CBC was most commonly detected in segment 1 (50%), 8 (48.3%), 7 (41.2%), and 4 (40%). CBC was more frequent in the right lobe (40.4%) and Gharbi stage 3 (41.8%) and 4 (55.6%) lesions. There were no differences in CBC according to distance from the hilus. In addition, preoperative total bilirubin, direct bilirubin, alkaline phosphatase (ALP), and gamma-glutamyl transferase (GGT) elevations were associated with higher CBC frequency (P<0.05). Cyst diameter, number of cysts, and ALP and GGT elevations were independent predictors of CBC presence. Conclusion The evaluation of hydatid cyst diameter, morphological stage, and segmental and lobar localization by abdominal CT and measurement of preoperative cyst diameter, number of cysts, and ALP and GGT values may predict the presence of CBC.

    Silver nucleolar organiser region (AgNOR) counts were performed on apical periodontal cysts, dentigerous cysts, odontogenic keratocysts, ameloblastomas and basal cell carcinomas. Significant differences, but with excessive overlap, were shown between dentigerous cysts and apical periodontal cysts and between odontogenic keratocysts and apical cysts. The mean AgNOR counts for all odontogenic cysts ranged between 2.02 and 2.65, and for ameloblastomas were 2.24, indicating that the method has neither a diagnostic nor a prognostic value in these lesions. Control oral squamous cell carcinoma tissues had significantly higher AgNOR counts than any other lesion tested.

    Within the past few decades, there has been a dramatic increase in the detection of incidental pancreatic cysts. It is reported a pancreatic cyst is identified in up to 2.6% of abdominal scans. Many of these cysts, including serous cystadenomas and pseudocysts, are benign and can be monitored clinically. In contrast, mucinous cysts, which include intraductal papillary mucinous neoplasms and mucinous cystic neoplasms, have the potential to progress to pancreatic adenocarcinoma. In this review, we discuss the current management guidelines for pancreatic cysts, their underlying genetics, and the integration of molecular testing in cyst classification and prognostication.

    The AC dipole is an oscillating dipole magnet which can induce large amplitude oscillations without the emittance growth and decoherence. These properties make it a good tool to measure optics of a hadron synchrotron. The vertical AC dipole for the Tevatron is powered by an inexpensive high power audio amplifier since its operating frequency is approximately 20 kHz. The magnet is incorporated into a parallel resonant system to maximize the current. The use of a vertical pinger magnet which has been installed in the Tevatron made the cost relatively inexpensive. Recently, the initial system was upgraded with a more powerful amplifier and oscillation amplitudes up to 2-3{sigma} were achieved with the 980 GeV proton beam. This paper discusses details of the Tevatron AC dipole system and also shows its test results.

    AC-3 is a system for coding up to 5.1 channels of audio into a low bit-rate data stream. High quality may be obtained with compression ratios approaching 12-1 for multichannel audio programs. The high compression ratio is achieved by methods which do not increase decoder memory, and thus cost. The methods employed include: the transmission of a high frequency resolution spectral envelope; and a novel forward/backward adaptive bit allocation algorithm. In order to satisfy practical requirements of an emissions coder, the AC-3 syntax includes a number of features useful to broadcasters and consumers. These features include: loudness uniformity between programs; dynamic range control; and broadcaster control of downmix coefficients. The AC-3 coder has been formally selected for inclusion of the U.S. HDTV broadcast standard, and has been informally selected for several additional applications.

    2007-01-01

    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.

    Numerous procedures have been described for the operative management of acromioclavicular (AC) joint injuries. Some of these techniques, including hardware fixation and non-anatomical reconstructions, are associated with serious complications and high failure rates. Recently, AC joint reconstruction techniques have focused on anatomical restoration of the coracoclavicular ligaments to achieve optimal clinical outcomes. We used a triple endobutton technique to separately reconstruct the trapezoid and the coronoid portions of the coracoclavicular ligament. We evaluated the preliminary clinical and radiological results of this technique in patients with acute complete dislocation of the AC joint. All patients achieved a significant improvement in the pain and function of shoulder at a mean follow-up interval of 12 months (range, 8-14 months). Excellent reduction of the AC joint was maintained. The triple endobutton technique may be safe and effective for the treatment of acute complete AC joint dislocations.

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

    Retro-rectal cystic hamartoma (tailgut cyst), is an uncommon congenital developmental lesion, generally located in the retro-rectal space. Its diagnosis and approach is challenging because the retropelvic space is not familiar. We report a 51-year-old woman who presented with paresthesia and pain in perianal area. The magnetic resonance image showed high signal intensity on the T1-weighted image and iso to high signal intensity on the T2-weighted image of the retropelvic space and CT showed sacral bony defect. We chose the posterior approach for removal of the tailgut cyst. Histopathology exam of the retropelvic cyst revealed a multiloculated cyst containing abundant mucoid material lined by both squamous and glandular mucinous epithelium. The patient has recovered nicely with no recurrence. Tailgut cyst needs complete surgical excision for good prognosis. So, a preoperative high-resolution image and co-operation between neurosurgen and general surgeon would help to make safe and feasible diagnosis and surgical access. PMID:27073796

    An 11-week-old, male, Staffordshire Bull Terrier had a history of generalized ataxia and falling since birth. The neurologic findings suggested a localization in the cerebellum. Magnetic resonance imaging of the brain was performed. In all sequences the area of the cerebellum was almost replaced by fluid isointense to cerebrospinal fluid. A complete necropsy was performed after euthanasia. Histologically, the lesion was characterized by extensive loss of cerebellar tissue in both hemispheres and vermis. Toward the surface of the cerebellar defect, the cavity was confined by ruptured and folded membranes consisting of a layer of glial fibrillary acidic (GFAP)-positive glial cells covered multifocally by epithelial cells. Some of these cells bore apical cilia and were cytokeratin and GFAP negative, supporting their ependymal origin. The histopathologic features of our case are consistent with the diagnosis of an ependymal cyst. Its glial and ependymal nature as demonstrated by histopathologic and immunohistochemical examination differs from arachnoid cysts, which have also been reported in dogs. The origin of these cysts remains controversial, but it has been suggested that they develop during embryogenesis subsequent to sequestration of developing neuroectoderm. We speculate that the cyst could have been the result of a pre- or perinatal, possibly traumatic, insult because hemorrhage, and tissue destruction had occurred. To our knowledge, this is the first description of an ependymal cyst in the veterinary literature.

  9. Towards an Ecological Understanding of Dinoflagellate Cyst Functions

    2014-01-01

    The life cycle of many dinoflagellates includes at least one nonflagellated benthic stage (cyst). In the literature, the different types of dinoflagellate cysts are mainly defined based on morphological (number and type of layers in the cell wall) and functional (long- or short-term endurance) differences. These characteristics were initially thought to clearly distinguish pellicle (thin-walled) cysts from resting (double-walled) dinoflagellate cysts. The former were considered short-term (temporal) and the latter long-term (resting) cysts. However, during the last two decades further knowledge has highlighted the great intricacy of dinoflagellate life histories, the ecological significance of cyst stages, and the need to clarify the functional and morphological complexities of the different cyst types. Here we review and, when necessary, redefine the concepts of resting and pellicle cysts, examining both their structural and their functional characteristics in the context of the life cycle strategies of several dinoflagellate species.

The cases were analysed for age, sex, site and methods of management. Results show that developmental odontogenic cysts (57.14%) were more common than inflammatory odontogenic cysts (26.94%). Dentigerous cyst (22.22%) was the most common epithelial jaw cyst, followed by radicular cyst (21.43%). Developmental non-odontogenic cysts were more than twice as common in females as in males. Sixty-eight per cent of epithelial jaw cysts were treated by enucleation, 10% by marsupialisation, 13% by jaw resection and 9% by surgical excision.

    Conservative measures are the mainstay of therapy in adult polycystic kidney disease (APKD). Pain, infection and obstructive uropathy are the major indications for intervention. Chronic pain has been treated with narcotic analgesics, needle aspiration of dominant cysts, and open renal cyst decortication. Laparoscopic cyst decortication, by either transperitoneal or retroperitoneal access, is a new emerging option with similar efficacy to open surgery and less morbidity. Cyst infection in these patients responds poorly to commonly used antibiotics. Patients with refractory cyst infection may even require nephrectomy. Herein, we present 2 cases with APKD that were treated by retroperitoneoscopic decortication for painful and infected cysts. Both patients showed prompt and sustained improvement in symptoms, with minimal morbidity and short convalescence. This approach has not hitherto been described for infected cysts in APKD. The retroperitoneoscopic route should be preferred in the presence of infected cysts so as to prevent intraperitoneal contamination.

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

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

    The authors describe two patients with posterior thoracic pain associated with cysts of the septum posticum. One patient's pain was relieved by surgical removal of the cysts; the second patient's symptoms temporarily resolved after myelography. Posterior thoracic pain can be ascribed to myelographically proven arachnoid cysts when the pain is persistent, positionally exacerbated and associated with radicular sensory changes. Excision of the cysts may provide pain relief for some patients.

    Symptomatic Mullerian duct cyst is a rare entity in children. A 9-month-old male infant presented with bowel and urinary obstructive symptoms. Imaging investigations revealed a cystic mass in the rectovesical pouch compressing bladder neck and rectum. At laparotomy, a Mullerian duct cyst was found. Most of the cyst was excised and the remaining cyst mucosa was cauterized. The child improved thereafter. PMID:27672581

    A case of a rare odontogenic cyst arising in the lateral periodontal membrane in the mandible in a 14 year old girl is reported. This lesion appeared to be a new entity and has been named glandular odontogenic cyst (GOC) or sialo-odontogenic cyst. Histologically the lesion was lined by mucous producing cuboidal epithelium containing several areas of thickening and numerous duct-like structures. The cyst recurred with the same histology two years postoperatively.

    Splenic epidermoid cysts are rare non-parasitic true cysts affecting the spleen. We report a five-year-old child who presented with an abdominal lump associated with pain of 15 days. Ultrasonography of the abdomen showed a huge cystic lesion of obscure origin. At laprotomy a huge unilocular cyst involving upper part of spleen containing pultaceous fluid was seen and its removal necessitated splenectomy. Histopathological findings were consistent with splenic epidermoid cyst. Thus histopathology helped in elucidating the aetiology and diagnosis.

    We present the case of a 28-year-old competitive runner with iliotibial band (ITB) friction syndrome associated with a synovial cyst. Magnetic resonance imaging (MRI) did not demonstrate a fluid collection. However, open exploration revealed a large cyst beneath the ITB arising from the capsule of the knee proximal to the lateral meniscus. The cyst disappeared on extension. The pre-operative MRI scan may have revealed the cyst, if it had been taken with the knee flexed.

    Retroperitoneal epidermoid cysts are rare. The authors report a case of an 11-year-old boy with an asymptomatic subdiaphragmatic cyst, which was found incidentally during an investigation for hypertension. At laparoscopy, the cyst was densely adherent to the diaphragm, resulting in a pneumothorax during dissection. Nevertheless, the excision and the diaphragmatic repair could be completed laparoscopically without complication. Microscopic examination showed an epidermoid cyst. No similar case has been reported in the literature.

  8. Transsphenoidal cyst cisternostomy with a keyhole dural opening for sellar arachnoid cysts: technical note.

    A less invasive transsphenoidal approach with a keyhole dural opening for intrasellar arachnoid cysts is described. This approach was used to address seven sellar cystic lesions with suprasellar extension; they were six intrasellar arachnoid cysts (IACs) and one Rathke's cleft cyst (RCC). In all cases, preoperative MRI revealed cerebrospinal fluid (CSF) intensity on both T1- and T2-weighted images. On preoperative contrast-enhanced MRI, five of the six IACs manifested posterior displacement of the flattened pituitary gland toward the dorsum sellae; one of the six IACs and the RCC exhibited a flattened pituitary gland on the anterior surface of the cyst. Wide cyst cisternostomy through a keyhole dural opening was carried out safely using a microscope with the support of a thin angled endoscope (30° and/or 70°, diameter 2.7 mm). As we aimed to avoid iatrogenic injury of the pituitary function, we found it difficult to obtain a sufficiently wide and precise opening of the cyst wall when the pituitary gland was located on the anterior surface of the cyst wall. Our approach facilitates safe cyst cisternostomy as wide as that obtainable by transcranial manipulation. In addition, CSF leakage is prevented by dural plasty using the fascia lata and stitching with 6-0 monofilament sutures. This technique can be adapted to address various sellar cystic lesions. However, as the posterior or anterior displacement of the normal pituitary gland in the presence of IACs or RCCs, respectively, affects the width of the cyst opening, our technique is more suitable for IACs than RCCs.

    We describe two rare cases of frontal cystic lesions presenting with symptoms and signs of raised intracranial pressure. Both had a preoperative diagnosis of an arachnoid cyst and were subjected to a craniotomy with marsupialization of the cyst. However, the histology confirmed them to be an endodermal cyst (EC) on both occasions. Both the patients have been closely followed with no recurrence of symptoms. ECs of the central nervous system are usually reported in the spinal canal, mid-line posterior fossa, and the suprasellar regions. Supratentorial and non-midline ECs are rare, with only about 22 cases previously reported in literature. We discuss both the cases and review the relevant literature. PMID:27366267

    Congenital pericardial diverticula and cysts are extremely uncommon lesions within the anterior mediastinum. Both lesions derive from the pericardial celom and represent different stages of a common embryogenesis. Initial reports date from the 19th century. Surgical pioneers were Otto Pickhardt, who removed a pericardial cyst at Lenox Hill Hospital in New York in 1931, and Richard Sweet, who accomplished the first resection of a pericardial diverticulum at Massachusetts General Hospital in Boston in 1943. These lesions were also called spring water cysts because they usually contain watery, crystal-clear fluid. This history outlines the milestones of evolving surgical management, from the first report in 1837 up to the present time. PMID:22719140

    Meniscal cysts are a rare disease constantly combined with a horizontal meniscal lesion. Currently, nuclear magnetic resonance (MRI) is the main diagnostic tool, because of its high sensitivity and specificity, and decompression arthroscopy combined with selective meniscectomy is the treatment of choice. The Authors report a case of a voluminous medial meniscal cyst where instrumental examination, MRI, was fundamental for the preoperative diagnosis of the horizontal meniscal lesion causing the cystic degeneration of the meniscus. The treatment performed was selective meniscectomy of the body and posterior horn of the medial meniscus and decompression of the voluminous cyst by arthroscopy. Physical examination after six months showed the complete resolution of swelling at the medial hemirima, no walking pain and normal range of motion.

    Adrenal cysts are rare and mostly silent clinically. Herein we report a case of adrenal cyst. A 55-year-old female was incidentally found to have a left suprarenal cystic lesion with a calcified wall by abdominal sonography during a work-up for her epigastralgia and left flank pain. Then, computed tomography (CT) revealed a left adrenal cystic mass with wall calcification, magnetic resonance imaging (MRI) showed left retroperitoneal cystic mass with fluid content, and angiography demonstrated an avascular lesion. Surgical exploration was performed via a flank incision and a calcified cystic adrenal mass was excised. The pathologic diagnosis was adrenal pseudocyst with calcified wall. We discuss the diagnosis and management of adrenal cyst and briefly review the literature.

    1989-07-01

    The sonographic findings observed in four patients with primary retroperitoneal cysts were reviewed. All lesions presented as fluid-filled masses with anechoic content and regular margins; all increased through transmission. Preoperative location of the cysts within the retroperitoneal space was possible in all cases by either real-time ultrasound (US) analysis of the different relationships of the kidneys and the cysts during respiratory movements or the anterior displacement of surrounding structures. A differential diagnosis among retroperitoneal lesions containing fluid is difficult and cannot be obtained with imaging methods alone. However, preoperative knowledge of both the retroperitoneal location of the disease process and its fluid content may help to narrow the diagnostic possibilities, thus allowing the surgeon to more accurately plan the therapeutic approach to the patient.

    Only a few subdiaphragmatic bronchogenic cysts are described, and their occurrence in the retroperitoneum is extremely rare. So far, only a few cases have been reported in the English-language literature. The pathogenesis is caused by the pinching off of irregular lung budding of the primitive ventral foregut, with aberrant migration into the abdomen before fusion of the diaphragm during embryonal development. A unique case with clinical, radiographic, surgical finding is presented. Final pathological findings confirmed the diagnosis of retroperitoneal bronchogenic cyst without other associated congenital anomalies. Retroperitoneal bronchogenic cyst, although rare, should be considered in the differential diagnosis in the retroperitoneal mass. This rare case is described and the relevant literature, reviewed.

    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.

    1997-01-01

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

    Hydatid disease is endemic in some Mediterranean countries. Kidney is a relatively rare site, representing 2 to 3 % of all visceral sites. The diagnosis of hydatid cyst of the kidney is suspected in epidemiological, clinical, radiological and biological arguments. It remains clinically silent for a long time and only presents at the stage of complications. Ultrasound can suspect the hydatid nature of the lesion in 50 % of cases. Computed tomography and magnetic resonance imaging are helpful in the event of problem of differential diagnosis. The standard treatment for renal hydatid cyst is resection of the prominent dome and nephrectomy is indicated in cases of destroyed kidney.

    Small asymptomatic cysts of the pineal gland represent a common incidental finding in adults undergoing computerized tomography or magnetic resonance (MR) imaging or at postmortem examination. In contrast, large symptomatic pineal cysts are rare, being limited to individual case reports or small series. The authors have reviewed 24 cases of large pineal cysts. The mean patient age at presentation was 28.7 years (range 15 to 46 years); 18 were female and six male. Presenting features in 20 symptomatic cases included: headache in 19; nausea and/or vomiting in seven; papilledema in five; visual disturbances in five (diplopia in three, "blurred vision" in two, and unilateral partial oculomotor nerve palsy in one); Parinaud's syndrome in two; hemiparesis in one; hemisensory aberration in one; and seizures in one. Four lesions were discovered incidentally. Magnetic resonance imaging typically demonstrated a 0.8- to 3.0-cm diameter mass (mean 1.7 cm) with homogeneous decreased signal intensity on T1-weighted images, increased signal intensity on T2-weighted images, and a distinct margin. Hydrocephalus was present in eight cases. The cysts were surgically excised via an infratentorial/supracerebellar approach (23 cases) or stereotactically biopsied (one case). Histological examination revealed a cyst wall 0.5 to 2.0 mm thick comprised of three layers: an outer fibrous layer, a middle layer of pineal parenchymal cells with variable calcification, and an inner layer of hypocellular glial tissue often exhibiting Rosenthal fibers and/or granular bodies. Evidence of prior hemorrhage, mild astrocytic degenerative atypia, and disorganization of pineal parenchyma were often present. Postoperative follow-up review in all 24 cases (range 3 months to 10 years) revealed no complications in 21, mild ocular movement deficit in one, gradually resolving Parinaud's syndrome in one, and radiographic evidence of a postoperative venous infarct of the superior cerebellum with ataxia of 1 week

    An 8-year-old boy presented for oculoplastic evaluation of bilateral microphthalmia. He had multiple other congenital anomalies, including microcephaly, wide-spaced teeth, sloping shoulders, protruding ears, syndactyly, a posterior urethral valve, cystic dysplasia of the kidneys, and a bicuspid aortic valve. Taken together, these findings supported the diagnosis of Lenz microphthalmia syndrome. CT of the orbits revealed bilateral microphthalmic globes with associated colobomatous cysts. To the authors' knowledge, this is the first reported case of Lenz microphthalmia syndrome with associated orbital cysts.

    Urachal abnormalities represent a rare pathology and, in case of presence, they are more frequent in children and, among adults, in men. We report a case of urachal cyst in an adult woman in whom it was difficult to determine preoperatively the origin of the abdominal tumor. Positive diagnosis and treatment implied surgical exploration and resection. Even rare, this pathology should be considered in the differential diagnosis of an abdominal cyst. While the diagnosis may be established by clinical examination and imaging methods, surgical exploration is justified and, besides, offers the therapeutic opportunity.

    A case is presented of fistula formation between a primary hydatid cyst and the abdominal aorta which we believe is the first in the world literature. The patient underwent surgery with a diagnosis of aneurysm of the coeliac trunk. During the operation the presence was discovered of a hydatid cyst opening into the aorta. It was dealt with by partial resection and closing of the communication. Three months later the patient was readmitted with a new bleeding episode which resulted in a fatal outcome.

    Laparoscopic resection of a giant retroperitoneal, mesenteric cyst in a 38-year-old man who presented with abdominal distension and pedal edema is described. The diagnosis was made by abdominal computed tomography, which revealed a large cystic mass that was causing extrinsic compression of the inferior vena cava and the right ureter. The hospital course was uneventful, and the patient was discharged 2 days postoperatively. This new endoscopic approach offers a useful alternative to the traditional transabdominal excision of a mesenteric cyst and may have some theoretical advantages, including less postoperative pain and shorter convalescence.

    Benign abdominal cystic tumors are rare. They include retroperitoneal, mesenteric, and omental cysts. Most of these lesions present with vague abdominal pain and nausea. Less commonly they will present with bowel obstruction due to external compression. The diagnosis of these tumors is by abdominal ultrasound or computed tomography. Surgical enucleation is the treatment of choice. Laparoscopic surgical techniques are replacing or complimenting open abdominal surgical procedures. As the indications for these techniques increase, newer applications will arise. Presented here is a case of laparoscopic excision of a mesenteric cyst.

    Mesenteric and retroperitoneal cysts develop from ectopic lymphatic tissue. Most of them present as symptomless abdominal swellings or are found coincidentally during abdominal operations. One third of patients may present with acute abdominal pain, and few may present with chronic abdominal pain. However, mesenteric cyst presenting as inguinal hernia is extremely rare. Only four cases have been reported in the English-language literature. The present case is the fifth, and only the second from this subcontinent. The treatment of choice is complete surgical excision.

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

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

    1997-05-01

    The maize transposable element Ac is highly active in the heterologous hosts tobacco and tomato, but shows very much reduced levels of activity in Arabidopsis. A mutagenesis experiment was undertaken with the aim of identifying Arabidopsis host factors responsible for the observed low levels of Ac activity. Seed from a line carrying a single copy of the Ac element inserted into the streptomycin phosphotransferase (SPT) reporter fusion, and which displayed typically low levels of Ac activity, were mutagenized using gamma rays. Nineteen mutants displaying high levels of somatic Ac activity, as judged by their highly variegated phenotypes, were isolated after screening the M2 generation on streptomycin-containing medium. The mutations fall into two complementation groups, iae1 and iae2, are unlinked to the SPT::Ac locus and segregate in a Mendelian fashion. The iae1 mutation is recessive and the iae2 mutation is semi-dominant. The iae1 and iae2 mutants show 550- and 70-fold increases, respectively, in the average number of Ac excision sectors per cotyledon. The IAE1 locus maps to chromosome 2, whereas the SPT::Ac reporter maps to chromosome 3. A molecular study of Ac activity in the iae1 mutant confirmed the very high levels of Ac excision predicted using the phenotypic assay, but revealed only low levels of Ac re-insertion. Analyses of germinal transposition in the iae1 mutant demonstrated an average germinal excision frequency of 3% and a frequency of independent Ac re-insertions following germinal excision of 22%. The iae mutants represents a possible means of improving the efficiency of Ac/Ds transposon tagging systems in Arabidopsis, and will enable the dissection of host involvement in Ac transposition and the mechanisms employed for controlling transposable element activity.

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

    Cysts are rare lesions of the spleen, and may be divided into parasitic and non-parasitic types. After the parasitic cysts, the second most frequent group is the (secondary) posttraumatic form of non-parasitic cysts. The primary form (congenital and neoplastic) of the latter is the least frequent. Whereas splenectomy was the treatment of choice for lienal cysts until a few years ago, a change has occurred in the techniques of splenic salvage. Against the background of a case report of a primary epidermoid cyst the etiology, diagnostic measures, and the recent developments in conserving spleen surgery are discussed.

    In trophozoites and cysts of Balantidium coli the contents of nucleic acids were compared, with the use of cytochemical methods. There is more RNA (nuclear and cytoplasmatic) in trophozoites, but the content of DNA is the same in both trophozoites and cysts. Some morphometric parameters, allowing to compare trophozoites and cysts of B. coli, were obtained on the basis of cytophotometric determination of the cytochemical reactions' intensity and its computer analysis. These studies showed greater compactness of nuclear chromatin, higher homogeneity of chromatin's structures in cysts in comparison with trophozoites, and finally, decrease in the circumference and area of cysts of B. coli.

    Bronchogenic cysts are generally found in the mediastinum, particularly posterior to the carina, but they rarely occur in such unusual sites as the skin, subcutaneous tissue, pericardium, and even the retroperitoneum. A 30-year-old Korean man underwent surgery to remove a cystic adrenal mass incidentally discovered during routine physical checkup. At surgery, it proved to be a multilocular cyst located in the retroperitoneum adjacent to the left adrenal gland. Microscopically, the cyst was lined by respiratory epithelium over connective tissue with submucous glands, cartilage and smooth muscle, thereby histologically confirming bronchogenic cyst. This is the first reported case of retroperitoneal bronchogenic cyst in an adult without other congenital anomalies in Korea.

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

    The cyst stage of Entamoeba histolytica is a promising therapeutic target against human amoebiasis. Our research team previously reported the production in vitro of Cyst-Like Structures (CLS) sharing structural features with cysts, including rounded shape, size reduction, multinucleation, and the formation of a chitin wall coupled to the overexpression of glucosamine 6-phosphate isomerase, the rate-limiting enzyme of the chitin synthesis pathway. A proteomic study of E. histolytica trophozoites, cysts, and in vitro-produced CLS is reported herein to determine the nature of CLS, widen our knowledge on the cyst stage, and identify possible proteins and pathways involved in the encystment process. Total protein extracts were obtained from E. histolytica trophozoites, CLS, and partially purified cysts recovered from the feces of amoebic human patients; extracts were trypsin-digested and analyzed by LC-MS/MS. In total, 1029 proteins were identified in trophozoites, 550 in CLS, and 411 in cysts, with 539, 299, and 84 proteins unique to each sample, respectively, and only 74 proteins shared by all three stages. About 70% of CLS proteins were shared with trophozoites, even though differences were observed in the relative protein abundance. While trophozoites showed a greater abundance of proteins associated to a metabolically active cell, CLS showed higher expression of proteins related to proteolysis, redox homeostasis, and stress response. In addition, the expression of genes encoding for the cyst wall proteins Jessie and Jacob was detected by RT-PCR and the Jacob protein identified by Western blotting and immunofluorescence in CLS. However, the proteomic profile of cysts as determined by LC-MS/MS was very dissimilar to that of trophozoites and CLS, with almost 40% of hypothetical proteins. Our global results suggest that CLS are more alike to trophozoites than to cysts, and they could be generated as a rapid survival response of trophozoites to a stressful condition

    2013-02-01

    Colloid cysts are among rare benign tumours of the third ventricle. Although the most frequent symptoms are headache and syncope, arrest hydrocephalus or sudden death could appear with colloid cysts. The aim of this pictorial essay was to increase awareness of the clinical presentation, computed tomography (CT) and magnetic resonance (MR) imaging spectrum, and treatment options of the colloid cysts. The data of 11 patients with histopathologically and/or clinically proven colloid cyst were analysed, retrospectively; and the neuroradiologic appearances of the cysts were evaluated. The CT and MR appearance of colloid cysts may change, depending on the viscosity or the cholesterol content of the cysts. However, the cystic content is the most important factor that could affect the success of treatment. Cysts that are especially rich in protein and cholesterol tend to be hyperdense on CT, hypointense on T2-weighted sequences and hyperintense on T1-weighted sequences. These cysts are viscous, and the success of aspiration is significantly low. In the diagnosis and evaluation of small-sized cysts that have an ingredient similar to cerebrospinal fluid, 3-dimensional sequences might be useful. The radiologic appearances of colloid cysts could play an important role in directing these patients to alternative surgical modalities, including resection. PMID:22575594

    The development and appearance of hydatid cysts of Echinococcus granulosus in experimentally infected tammar wallabies (Macropus eugenii) and sheep during the period 9-17 months post-infection (mpi) were studied. Cysts of unknown age were also examined from mature, naturally infected sheep. The cysts grew more rapidly and became fertile within a shorter period in wallabies compared with sheep. Cysts from the wallabies were larger in absolute size and were larger relative to the size of the lungs. Microscopical examination revealed that wallaby hydatid cysts developed in small bronchioles. Hydatid cysts in the wallabies had a thicker germinal membrane, with more nuclei and a thicker laminated layer (LL), than hydatid cysts of similar age found in sheep. In contrast, the adventitial layer was thicker in the ovine cysts, comprising a hyalinized layer of degenerate collagen and necrotic cellular debris surrounded by a layer of granulation tissue that was largely absent from lesions in the wallabies. Multilocular cysts were present in sheep, but not in wallabies. The greater thickness of the germinal membrane in wallaby cysts suggests greater parasite activity, which may explain the more rapid growth rate in this host, whereas the thicker adventitial layer in sheep cysts may be restrictive to growth while simultaneously protecting the hydatid from the host immune response. These differences in the parasite-host relationship between macropods and sheep may reflect the relatively recent introduction of the parasite into Australia. PMID:20846666

    Purpose: We report a case of iris pigment epithelial cysts in a newborn and discuss the importance of an accurate diagnosis for prevention of amblyopia. Methods: We describe a case of an abnormal red reflex seen on a newborn exam. Results: A full-term female born via normal spontaneous vaginal delivery without any complications was seen in the newborn nursery. She was noted to have an abnormal eye exam. Pupils were large with circular dark excrescences of the iris pigment epithelium. She was referred to a pediatric ophthalmologist where she was noted to fixate and follow faces. No afferent pupillary defect was seen. OD red reflex was normal whereas OS red reflex was blocked mostly by dark excrescences. A 2–3 mm dark brown lesion was seen in the OD iris and a 3–5 mm dark brown lesion was seen in the OS iris, consistent with a pupillary iris pigment epithelial cyst. Central visual axis was clear OU. Glaucoma was not present and patching was not performed. Observations and clinical photographs were recommended with follow-up in three months. Conclusion: Iris pigment epithelial cysts are uncommonly seen in children. The primary care provider first seeing a newborn must be aware of lesions obscuring a red reflex with appropriate follow-up. Follow-up in three months with IOP measurements is recommended. Iris pigment epithelial cysts in children may be a cause of amblyopia, thus prompt evaluation is important for prognostic purposes and the prevention of amblyopia. PMID:27625966

    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.

This was confirmed by an aortogram. It is important to be aware of the coexistence of these anomalies to make a diagnosis preoperatively. Images PMID:8016803

    The retrovesical hydatid cyst is a very rare site. The authors have observed six cases over a 12-year period. The diagnosis is often delayed. The clinical features are dominated by pain and compression of adjacent organs. Clinical examination sometimes reveals a hypogastric mass. The topographic diagnosis is based on ultrasonography and IVU. Treatment is surgical: retroperitoneal cystopericystectomy. The course is often favourable.

    The retroperitoneal bronchogenic cyst is an extremely rare anomaly. During the examination of an 18-year-old female patient due to her extreme thinness, the abdominal ultrasound and later the CT indicated as an accidental finding--a left side adrenal/suprarenal adenoma, which turned out to be hormonally inactive. But while we were doing a laparoscopic surgical intervention we found a 6-8-cm cyst in the retroperitoneum, between the greater curvature and the spleen. It contained light grey, mucinous liquid. The left suprarenal gland had normal size and appearance. During the microscopic examination the removed terime showed cystic structures, which were covered inside with multilayer ciliated columnar epithelium, mucous excretory glands, a whole layer of connective/interstitial and smooth muscle tissue. Neither cartilage, nor gastrointestinal epithelium was found. Only a few publications have reported about retroperitoneal bronchogenic cyst so far. These lesions occur very rarely at the greater curvature. Although this alteration is really unusual, bronchogenic cysts have to be expected in the differential diagnostics of the retroperitoneal tumors.

    A cystic neck mass can be either malignant or benign; 22% of patients (4/18) admitted with the tentative diagnosis of branchial cyst in a recent 2-year period (1977-1979) had metastatic carcinoma: epidermoid, thyroid or salivary gland. Preoperative fine needle aspiration was diagnostic in 1 instance and unhelpful in 2. Frozen section analysis of the gross specimen invariably provided the correct diagnosis. All patients with malignancies had subclinical primary disease and in 1 instance random biopsies identified its origin. The prudent surgeon will avoid untoward results if he approaches a neck cyst in an adult as if it were malignant. Guidelines he can follow to prevent the inadvertent removal of a metastasis under the misapprehension that it is a benign neck cyst include: 1. Prior to operation, perform a thorough head and neck examination to identify a primary carcinoma; 2. Do a fine needle aspiration of the mass for cytology. A negative report must be considered inconclusive; 3. Make a gross examination in the operating room of the opened cyst and frozen section processing of suspicious areas; 4. Follow with a panendoscopy and random biopsies of appropriate areas and complete the neck dissection on the involved side, after a metastatic deposit has been recognized. The preoperative procurement of contingency consent for these procedures is understood.

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

    We present a case of a fetal pancreatic cyst, a rare disease in fetal life, detected prenatally at 30 weeks' gestation by ultrasound. Routine ultrasound examination at 30 weeks' gestation by primary obstetrician showed a cyst on the fetal abdomen. Initially, the suspected diagnosis was a mesenteric cyst. Subsequent ultrasound examination at weeks 32, 36 showed a fetal retroperitoneal cyst. A 3.6 kg female neonate was born to 23 yr old woman by spontaneous vaginal delivery at 38 weeks' gestation. The fetus underwent exploratory laparotomy. Histopathologic and immunohistochemical diagnosis revealed the cyst to be a pancreatic cyst. Surgical outcome was excellent. Thus, we report this case of a pancreatic cyst detected via prenatal ultrasonography.

    We report a cervical intraspinal cyst in a dog that was initially tetraparetic but spontaneously recovered completely. MRI revealed a well-demarcated intraspinal cyst located dorsally to a degenerated intervertebral disc. The location of the cyst and its signal features on MRI resembled those of discal cysts previously reported in humans. It has been reported in dogs that clinical signs of a intraspinal cyst are similar to those of intervertebral disc herniation and both conditions require surgical intervention. Unexpectedly, our case showed rapid spontaneous recovery and the follow-up MRI revealed complete resolution of the intraspinal cyst and spinal cord compression. Spontaneous recovery of degenerative intraspinal cyst may occur in dogs, similar to rare human cases as reported previously. PMID:19952512

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

    PubMed

    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.

    Oral mucoceles can be divided in two different forms, extravasation and retention cysts. The aim of this study was to identify the frequency of each form, sex- and age distribution, location, recurrences, referent and the differences between the two forms. A total of three-hundred-five cases were retrieved from the Department of Oral Pathology at the Institution of Odontology, The Sahlgrenska Academy at Göteborg University between 1993 and 2003. Seven referrals were disregarded because there was insufficient information, leaving 298 cases for this study. In relation to other studies, our study investigated a larger number of cases. Extravasation cysts were the most common type (258 cases). There was a slight predominance among women (55%) and the most frequent location was the lower lip (71%). 84% occurred between the ages of 0 and 40 years with peak incidence in the second decade (34%). 62% of the referrals came from specialists, 28% from general practitioners, and 10% from the Department of Oral Medicine. Retention cysts were not found as frequently as extravasation cysts (40 cases) and the occurrence in women was also a bit higher (58%). We found a more even distribution regarding age and location. The most common locations were floor of the mouth (25%), cheek (20%), and lower lip (18%). They occurred more often between the ages of 11 and 30 (31%), and between 50 and 80 (50%). 75% of the referrals came from specialists, 15% from general practitioners,and 10% from the Department of Oral Medicine. Recurrences were unusual for both cyst types. 17 cases of extravasation cysts were reported as recurrences and one case of retention cyst. PMID:19994562

    This article presents a narrative review of cystic lesions around the hip and primarily consists of 5 sections: Radiological examination, prevalence, pathogenesis, symptoms, and treatment. Cystic lesions around the hip are usually asymptomatic but may be observed incidentally on imaging examinations, such as computed tomography and magnetic resonance imaging. Some cysts may enlarge because of various pathological factors, such as trauma, osteoarthritis, rheumatoid arthritis, or total hip arthroplasty (THA), and may become symptomatic because of compression of surrounding structures, including the femoral, obturator, or sciatic nerves, external iliac or common femoral artery, femoral or external iliac vein, sigmoid colon, cecum, small bowel, ureters, and bladder. Treatment for symptomatic cystic lesions around the hip joint includes rest, nonsteroidal anti-inflammatory drug administration, needle aspiration, and surgical excision. Furthermore, when these cysts are associated with osteoarthritis, rheumatoid arthritis, and THA, primary or revision THA surgery will be necessary concurrent with cyst excision. Knowledge of the characteristic clinical appearance of cystic masses around the hip will be useful for determining specific diagnoses and treatments. PMID:26495246

    A radicular cyst is one of the furthermost everyday odontogenic cysts of the anterior maxilla, not regularly comprehended in youth. They are found mostly at the apices of the tooth (periapical cyst), lateral surface of the roots (lateral radicular cyst) and remains in the jaw after removal of the offending tooth (residual cyst). The radicular cyst has been catalogued as an inflammatory cyst, as an outcome to pulpal necrosis succeeding caries, with a linked periapical inflammatory reaction. They advance sluggishly and asymptomatic lest infected. Because of this they can extent to big dimensions. Many times it is perplexing to segregate radicular cysts from the obligatory pre-existing chronic periapical periodontitis lesions radiographically. Here, we present a rare case with bilateral radicular cyst in relation to first molar of the mandible in a 19-year-old. Orthopantomograph showed a large unilocular radiolucency with a well-defined border in the periapical region of the first molar on the left side extending from the root of the second premolar to the mesial root of the second molar. Correspondingly another well-defined unilocular radiolucency with a well-defined border was seen on the right side of the mandible. Several treatment possibilities are presented for a radicular cyst such as surgical endodontic treatment, extraction of the transgressing tooth, enucleation with primary closure, and marsupialization trailed by enucleation. The patient management comprised surgical enucleation of cystic sac followed by rehabilitation of the same area. PMID:25859111

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

    Objectives: To assess the association of adenomyotic foci with co-existing benign ovarian cysts. Methods: This prospective cross-sectional study consisted of 100 consecutive hysterectomy specimens referred to Histopathology Section of Pathology Department, Peshawar Medical College, Peshawar, Pakistan by its attached teaching hospitals from January 2011 to December 2012. Hematoxylin and eosin stained sections were examined for adenomyotic foci and the presence of co-existent ovarian cysts. For evaluation of estrogen receptor (ER) status immunohistochemical stains were applied and H-scoring system was used with a score >50 as positive. Results: Out of the 100 hysterectomy specimens, 25 cases had both adenomyosis and ovarian cysts. The ER status of adenomyotic foci was positive in 20% cases and negative in 80% cases. The commonest type of ovarian cyst was hemorrhagic luteal cyst (28%), followed by serous and mucinous cystadenoma (20%) each. Out of the 28% cases of functional cysts, 71.5% were ER positive and 28.5% were ER negative. The p-value for association of ER status of adenomyotic foci with functional cysts was 0.0004; however, p-value was not significant in comparing cases with controls. All 72% cases of nonfunctional cysts were ER negative. However, 44% of functional cysts were not associated with adenomyotic foci. Conclusion: This study concludes that besides functional ovarian cysts, other local factors may be responsible for the development of adenomyosis. PMID:27570851

    The aim of this research is to analyze the prevalence of dentigerous cysts (DCs) in a population-based cohort in British Columbia, Canada, and to report unusual cases associated with DC. The database of the British Columbia Oral Biopsy Service was searched from 1998 to 2007. 2082 histologically confirmed DCs from 2029 patients were retrieved and retrospectively analyzed for incidence, age, gender and ethnicity. The results show that this is a common jaw cyst with male predilection, has a peak incidence in younger adults and is more common in Caucasians. Multiple DCs, representing 2.5% of the cases, are not associated with any syndromes or systemic conditions. 0.5% DCs were associated with other cysts or tumours at the same site or the opposite side of the jaw. The authors report the first series of cases presenting clinically as bilateral DCs, but histologically as an odontogenic tumour or another type of odontogenic cyst. DCs can co-exist with other more serious conditions, such as odontogenic keratocyst or cystic ameloblastoma. This association with more significant conditions indicates the importance of histologically confirming any jaw cyst, even when it presents clinically as a classic DC.

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

    The calcifying odontogenic cyst (COC) was first delineated in 1962. It is a rare developmental odontogenic cyst with notable presence of histopathological features which include a cystic lining demonstrating characteristic "Ghost" epithelial cells with a propensity to calcify. In addition, the COC may be associated with other recognized odontogenic tumors. This gives rise to a spectrum of variants of COC according to clinical, histopathological, and radiological characteristics. Very few reports have actually captured the actual transformation while most reported cases are documents of co-existing lesions. This article presents one such entity, where the asymptomatic presentation misled the diagnosis and on histopathological examination revealed the COC with areas suggestive of adenomatoid odontogenic tumor.

    Epidermoid cysts (ECs) are uncommon, benign cystic lesions derived from the entrapment of surface epithelium or more often from the aberrant healing of infundibular epithelium during an episode of follicular inflammation. ECs occur anywhere on the body, particularly along embryonic fusion lines, most commonly on the face, scalp, neck, chest and upper back. Head and neck ECs constitute only about 7%, whereas only 1.6% of ECs are reported in the oral cavity. They comprise <0.01% of all the oral cysts. Floor of the mouth, tongue, lips, palate, jaws, etc., are some of the reported sites of ECs in the oral cavity. Microscopically, ECs are lined with plain stratified squamous epithelium filled with laminated layers of keratin. Here, we report two rare cases of ECs, one occurring in the gingival aspect and other in the lower third of face. The cases are reported due to rarity of ECs in the head and neck region.

    Dermoid cysts are benign lesions seen in young adults. The second most common localization is the floor of the mouth. They are usually asymptomatic over years but can be symptomatic due to secondary changes or the size. Herein, we report a case of 19-year-old woman who applied to emergency service with dyspnea, dysphagia and enlarging of a mass in the submental region. The patient cannot be entubated because of the mass pushing the tongue base backward closing the laryngeal view. Elective tracheostomy was performed for providing airflow during the operation. After the operation a cystic mass fulfilled with keratin lined by keratinized stratified squamous epithelium in addition to the dermal appendages such as sweat glands and follicular structures were seen histopathologically and the case was diagnosed as dermoid cyst of the submental region. In such patients with quick enlarging of mass causing airway obstructions, the tracheostomy can be the preferable method because of the difficulties in entubation. PMID:26999700

    Fabry disease is an inherited, X-linked lysosomal storage disorder caused by deficiency of the enzyme alpha galactosidase A (alpha-GLA A), which leads to glycosphingolipid accumulation, mainly globotriaosylceramide, in tissues. Disease prevalence and the index of suspicion are both low, which tends to result in delayed diagnosis and treatment. We present the case of a male Fabry disease patient who manifested no angiokeratoma lesions but presented multiple parapelvic cysts and renal failure. The genetic study revealed an alpha-GLA A gene mutation that had not been recorded in the mutations registry. The de novo mutation was not found in his relatives and it was not transmitted to his offspring. The large number and peculiar appearance of the parapelvic cysts led to the diagnosis. PMID:27061865

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

    Four cases of lateral cervical cysts were reported. All cyst walls were lined with keratinized stratified squamous epithelium, and contained lymph follicles with well-defined germinal centers. Ectopic salivary gland tissue was found in one case. Histochemical examination by the immunoperoxidase method revealed the existence of carcinoembryonic antigen (CEA). However, alpha-feto protein (AFP) and amylase were not detected in any of the cysts. The cyst fluid contained high levels of CEA and high titers of salivary type amylase, but AFP was negative. These results do not support any one of the theories concerning the etiology of cervical lymphoepithelial cysts. It seems likely that cysts derive from both epithelial remnants of the branchial apparatus and from salivary gland inclusions in lymph nodes.

    Fine needle aspiration cytology of 213 cases of different cystic lesions from various regions of body and different superficial organs was analysed in an attempt to present the experience of the authors in the diagnosis of such lesions. The predominant lesion diagnosed by fine needle aspiration cytology was adnexal cyst/sebaceous cyst (41 cases) followed by vascular hamartoma (40 cases) and thyroglossal cyst (9 cases). One hundred fifty-eight (74.2%) out 213 cases were confirmed histopathologically. There was false negative diagnosis in 14 cases (6.6%). The remaining 41 (19.2%) cases did not turn up for further treatment. The fallacies that have been recorded in the diagnosis of thyroid cysts, salivary gland cysts and breast cysts in respect of papillary cystic thyroid carcinoma, muco-epidermoid carcinoma of salivary gland and intraductal carcinoma with fibrocystic disease of breast respectively have been highlighted in the present study.

    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

    Molluscum contagiosum is a benign cutaneous viral infection which is caused by double- stranded DNA poxvirus. It affects mainly children and young adults and usually presents with single or multiple umblicated papules or nodules on face, arms, legs and anogenital regions. It may present in atypical size and clinical appearance in patients with altered or impaired immunity and rarely in immuncompetent patients. Herein we present an immuncompetent young adult patient with isolated giant molluscum contagiosum, which was mimicking epidermoid cyst clinically. PMID:27648389

    The urachus is the remnant of the cloaca, which in adults attaches the bladder dome to the umbilicus. After birth it obliterates and presents as the midline umbilical ligament. Patent urachal anomalies are usually detected in childhood. In adults they occur very rarely and the presentation and diagnosis may be occasionally challenging. We present and discuss the case of an infected urachal cyst found in a 30-year-old adult. PMID:25140240

    Goals: To examine the utility of integrated molecular pathology (IMP) in managing surveillance of pancreatic cysts based on outcomes and analysis of false negatives (FNs) from a previously published cohort (n=492). Background: In endoscopic ultrasound with fine-needle aspiration (EUS-FNA) of cyst fluid lacking malignant cytology, IMP demonstrated better risk stratification for malignancy at approximately 3 years’ follow-up than International Consensus Guideline (Fukuoka) 2012 management recommendations in such cases. Study: Patient outcomes and clinical features of Fukuoka and IMP FN cases were reviewed. Practical guidance for appropriate surveillance intervals and surgery decisions using IMP were derived from follow-up data, considering EUS-FNA sampling limitations and high-risk clinical circumstances observed. Surveillance intervals for patients based on IMP predictive value were compared with those of Fukuoka. Results: Outcomes at follow-up for IMP low-risk diagnoses supported surveillance every 2 to 3 years, independent of cyst size, when EUS-FNA sampling limitations or high-risk clinical circumstances were absent. In 10 of 11 patients with FN IMP diagnoses (2% of cohort), EUS-FNA sampling limitations existed; Fukuoka identified high risk in 9 of 11 cases. In 4 of 6 FN cases by Fukuoka (1% of cohort), IMP identified high risk. Overall, 55% of cases had possible sampling limitations and 37% had high-risk clinical circumstances. Outcomes support more cautious management in such cases when using IMP. Conclusions: Adjunct use of IMP can provide evidence for relaxed surveillance of patients with benign cysts that meet Fukuoka criteria for closer observation or surgery. Although infrequent, FN results with IMP can be associated with EUS-FNA sampling limitations or high-risk clinical circumstances. PMID:27332745

    Researches to specify a serologic diagnostic test capable of determining the stage of toxoplasmosis, whether recent or latent, have been hampered by lack of knowing the real time of infection. Studying the precise kinetics of the differential agglutination of acetone [AC]-fixed versus that of formalin [HS]-fixed tachyzoites (differential agglutination test or AC/HS test) by sera of mice during the course of toxoplasmosis and assessment of its value in the differentiation between recent and latent infections in mice were the aims of the present work. Experimental toxoplasmosis was induced in mice, sera were collected sequentially and AC/HS test, FAST-ELISA to determine levels of IgM and IgG and microscopic examination of brain for Toxoplasma cysts were done. Both AC and HS specific patterns in the AC/HS test were noted to be dependent on the time from the onset of infection. Acute patterns of the AC/HS test were observed early in infection till before the appearance of brain cysts. Non-acute patterns were obtained late on 28th day post infection coinciding with the disappearance of IgM, persistence of IgG and presence of cysts in brains. The AC antibody was high in the recent phase of infection, and then it declined to be replaced by high sustained level of HS antibody late in infection. In conclusion, in the presence of both IgM and IgG, the appearance of either equivocal pattern or the non-acute pattern in the AC/HS test is significant in ruling out acute infection in mice.

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

    2015-01-01

    Colloid cysts are usually located in third ventricle and are believed to be derived from either primitive neuroepithelium or endoderm. Patients may remain asymptomatic for long time while some can present with paroxysmal headache, gait disturbance, nausea, vomiting, behavioral changes, weaknesses of lower limbs, impaired memory, new learning disability and sudden death. Computed tomography usually reveals a well-defined round or oval nonenhancing lesion. Although magnetic resonance imaging (MRI) signal intensity of colloid cysts is variable, the most common appearance is hyperintensity in T1-weighted sequences and iso to hypointensity in T2-weighted sequences. Observation, stereotactic aspiration, microscopic or endoscopic approaches and shunt surgery are various management options. Transcallosal and transcortical microscopic (with or without tubular retractor) approaches are mainly useful in normal-sized and dilated ventricles respectively. Endoscopic technique is an effective alternative to microsurgical technique but total resection and long-term recurrence remains a concern. Utilization of two instruments, the bi port technique and tubular retractor can be helpful in selected patients to overcome limitations. Although total excision should be aimed, subtotal excision and coagulation of residual cyst wall usually results in good long-term results without any growth of remnant wall. Conversion to an open procedure may be required in some patients. PMID:26037175

    Background: Pineal tumors are very uncommon intracranial lesions, and endodermal cysts in this location are extremely rare. Case Description: A 49-year-old right-handed female presented with 3 weeks history of progressive dizziness and imbalance. Imaging studies showed 1.8 cm × 1.7 cm × 1.8 cm pineal lesion with small enhancing mural component displacing ventrally the quadrigeminal plate and narrowing of aqueduct of Sylvius without hydrocephalus. In addition, she was found with small interhemispheric lipoma, and small posterior falx possible meningioma. Cerebrospinal fluid markers obtained by lumbar puncture were all negative. She underwent tumor resection, and final pathology reported endodermal cyst. No new deficits were encountered, and her gait imbalance improved significantly by 3 months follow-up. Conclusions: With evidence of enlargement or symptomatic pineal lesions, surgical consideration is necessary. Among pineal lesions, endodermal cysts are extremely uncommon and although benign pathology, long-term follow-up is advised due to unknown chronic behavior. PMID:27217965

    A 69-year-old female with unremarkable past history underwent endoscopy for dyspepsia. She denied weight loss or anorexia. Upper endoscopy revealed a bulge in the lesser curvature and posterior wall of the stomach with 4-5 cm. Endoscopic ultrasound was performed which showed a heterogeneous lesion, anechogenic in the major part, with a floating membrane inside, the greatest diameter of 90.8 × 17.2 mm, originated in the left liver lobe. Surgical resection was performed. Pathologic examination revealed a cystic lesion with an acellular thick fibrous wall, surrounded by a conspicuous inflammatory reaction. The cyst wall revealed a characteristic lamellar pattern of the fibers. In the internal surface of the lesion, there were remains of membranous structures, amidst which a vestigial Protoscolex was noted. In the presented case, a floating membrane was observed, which is a pathognomonic feature, establishing the diagnosis of hydatid cyst type 3. Fine needle aspiration guided by ultrasound was not performed due to the certainty in the diagnosis. To the authors' knowledge, these are the first images by endoscopic ultrasound of hydatid cyst of liver presented as a bulge in the stomach with pathognomonic features, which allowed the definitive diagnosis with no need for further diagnostic tests.

    The parathyroid cyst is a very infrequent entity, so much so that only round about 200 cases have been described up to now. It can be functional and non-functional. The studies of image don't clarify to us if procedence becomes of parathyroid or it has another origin, and the diagnosis is made with the analysis come from the liquid obtained in the puncture aspiration, where high PTH's concentrations are seen. Surgery is the treatment for functional cysts and the puncture aspiration for non- functional, the fact that they use to get solved with only one but sometimes is necessary to repeated it, even more than one time, keeping for the surgery when recurrent. We presented a clinical case of recurrent parathyroid cyst and his natural evolution, due to patient rejects surgery, being necessary repeated punctures. It hasn't become malignant after 10 years and his functional status wasn't changed, being necessary to accomplish repeated punctures aspirations each 2-3 months for local bothers.

    Periapical lesions, as well as periodontal disease, seems to have cyclic patterns of evolution. Periods of burst may be intercalated with periods of quiescence. Because keratinocyte division must occur during cyst growth, it is presumed that epithelium status could indicate the biological activity of radicular cysts (RCs). Th1 and Th2 are important heterogeneous stages of lymphocyte differentiation. Delayed-type hypersensitivity immune reactions are mediated by Th1 lymphocytes, whereas Th2 populations mediate some types of humoral immune response. Th2 lymphocytes are characterized by high expression of CD30 glycoprotein. Th1 and Th2 lymphocytes have not been evaluated in periapical inflammatory lesions. The purpose of this study was to evaluate CD30+ cells in RCs with atrophic and hyperplastic epithelium. A biotin-streptavidin amplified system was used for identification of CD30 receptor. Results demonstrate increased proportions of Th2 cells in cysts with hyperplastic epithelium. Our results suggest that Th2 cells could be associated with RC growth.

    A 59-year-old hypertensive man was referred to our hospital with a retroperitoneal cystic tumor, measuring 6 cm in diameter that was detected by an ultrasound examination during routine check-up 2 years before coming to our department. During the 2-year follow-up, the cystic tumor gradually increased in size. The patient also became hypertensive with slightly elevated urine levels of noradrenaline and dopamine, while the plasma catecholamines and their metabolites in the urine were within the normal range. Computed tomographic scanning and magnetic resonance imaging revealed a dumbbell-shaped retroperitoneal cyst with dense fluid, measuring 7 x 3.5 x 3 cm in diameter, in the left supra-adrenal and sub-diaphragmatic regions. He underwent extirpation of the cystic tumor with suspicion of adrenal endocrine cystic tumor. The histopathological diagnosis was a bronchogenic cyst, which is an extremely rare developmental anomaly in the retroperitoneal space. We herein report this rare case of retroperitoneal bronchogenic cyst and present a brief review of the previously reported 30 Japanese cases.

    We report the results of a MR velocity study of the cerebrospinal fluid including 36 patients with syringomyelic cysts (25 with a foraminal syringomyelia, 7 with a post-traumatic cyst, 2 with a tumoral spinal cord cyst, 2 with a spinal arachnoiditis). Velocity measurements were performed in the cysts and in the pericystic subarachnoid spaces and compared with clinical data, evolutive pattern of the disease, cyst volume, degree of stenosis of the cranio-cervical junction (in patients with Chiari I) or of the spinal canal (in post-traumatic cases), and with the extension of the cyst (post-traumatic cases). Cyst velocities correlated in the pre operative course with the clinical status of the patients and with the volume of the cyst. Correlation with the degree of foraminal stenosis was uncertain and no correlation was found with the duration of the disease course. In the post-operative course cyst velocity decreased and velocity of the subarachnoid spaces increased. Onset of the systolic peak occurred sooner in the cyst than in the subarachnoid spaces. We believe that this point may be important in the pathogenesis of the disease. We consider that systolic and diastolic cyst velocities respectively greater than 2.3 cm/s and 1.5 cm/s in the post-operative course may characterize aggressive cysts. In the future comparison of velocity measurements in patients with Chiari I without syrinx and patients with Chiari I related syringomyelia may be helpful for a better understanding of the natural history of the syringomyelia.

    Bronchogenic cysts are relatively rare congenital anomalies that represent malformations of the embryonic foregut and are morphologically expressed as maldevelopments of the respiratory system. Anatomically, they can be positioned at any location along the central axis of the respiratory system, but are more commonly discovered in the thorax. Infradiaphragmatic bronchogenic cysts are rare and retroperitoneal ones distinctly unusual. We report a retroperitoneal bronchogenic cyst clinically masquerading as a phaeochromocytoma.

    Urachal anomalies are usually found in early childhood or just after birth. These usually involve patent ductus urachus, urachal cyst, umbilical-urachal sinus or vesicourachal diverticulum. Very rarely are urachal anomalies found in adults, usully as an infected urachal cyst. We are presenting a case of surgically removed giant urachal retroperitoneal cyst that was found by chance during the abdominal ultrasound examination of a 22 year old man who was initially treated for idiopathic hypertension.

    The authors report a rare case of hydatid cyst of the psoas muscle in a 28-year-old woman, operated for vertebrospinal hydatid cyst. The patient presented with a left iliac fossa mass. Ultrasonography and computed tomography contributed to the preoperative diagnosis, despite negative hydatid serology. A retroperitoneal approach by left lumbotomy with partial pericystectomy was performed. In the light of this case, the authors discuss the diagnostic and therapeutic problems raised by hydatid cyst of the psoas muscle.

    This report describes a case of orthokeratinized odontogenic cyst arising in the mandibular molar region of a 39-year-old man. Under the initial clinical diagnosis of radicular cyst, root canal treatment was performed on the mandibular right second molar. The treatment that continued for six months did not achieve healing. Subsequently surgical intervention was selected since the tooth fracture was found, and the prognosis was judged to be poor. After atraumatic tooth extraction, the apical cystic lesion was enucleated, and the tooth was replanted. A definite diagnosis of orthokeratinized odontogenic cyst was made by histopathological examination of the biopsy specimen. The radiograph taken seven months after the operation showed an improvement in the radiolucent lesion. No clinical signs of tooth mobility, pain, and swelling were present. The tooth was then successfully retained with the final restoration. Careful follow-up is needed in order to detect any signs of recurrence.

    An apparatus and method is provided for monitoring a plurality of analog ac circuits by sampling the voltage and current waveform in each circuit at predetermined intervals, converting the analog current and voltage samples to digital format, storing the digitized current and voltage samples and using the stored digitized current and voltage samples to calculate a variety of electrical parameters; some of which are derived from the stored samples. The non-derived quantities are repeatedly calculated and stored over many separate cycles then averaged. The derived quantities are then calculated at the end of an averaging period. This produces a more accurate reading, especially when averaging over a period in which the power varies over a wide dynamic range. Frequency is measured by timing three cycles of the voltage waveform using the upward zero crossover point as a starting point for a digital timer. 24 figs.

    The present HVAC equipments for the residential buildings in the Hot-summer-and-Cold-winter climate region are still at a high energy consuming level. So that the high efficiency HVAC system is an urgently need for achieving the preset government energy saving goal. With its advantage of highly sanitary, highly comfortable and uniform of temperature field, the hot-water resource floor radiation heating system has been widely accepted. This paper has put forward a new way in air-conditioning, which combines the fresh-air supply unit and such floor radiation system for the dehumidification and cooling in summer or heating in winter. By analyze its advantages and limitations, we found that this so called Cooling/ Heating Floor AC System can improve the IAQ of residential building while keep high efficiency quality. We also recommend a methodology for the HVAC system designing, which will ensure the reduction of energy cost of users.
