    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

    Objective. To investigate whether the injection of Ethibloc into aneurysmal bone cysts can be an effective treatment modality.Design and patients. Ethibloc is an alcoholic solution of zein (corn protein) which has thrombogenic and fibrogenic properties. Ten patients with aneurysmal bone cysts were treated with CT-guided percutaneous injection of Ethibloc into the cyst cavity. Ethibloc injection was the primary treatment in five patients. Four patients had recurrence following previous curettage and bone grafting and one patient had not responded to injection into the lesion of autologous iliac crest bone marrow aspirate. Three patients needed a second injection. The median follow-up was 27 (6-60) months.Results and conclusion. Symptoms were relieved in all patients. At imaging, seven patients had resolution of the lesion and three had partial response at the most recent follow-up. Complications consisted of a local transitory inflammatory reaction in two patients and an aseptic abscess in one patient. This relatively simple, minimally invasive procedure makes an operation unnecessary by stopping the expansion of the cyst and inducing endosteal new bone formation. This technique may be used as the primary management of aneurysmal bone cysts excluding spinal lesions. (orig.)

  4. A radiographic study of solitary bone cysts

    International Nuclear Information System (INIS)

    The aim of this study was to evaluate the clinical, radiographic and histopathologic features of 23 cases of solitary bone cyst by means of the analysis of radiographs and biopsy specimens in 23 persons visited the Department of Oral and Maxillofacial Radiology, School of Dentistry, Kyung Hee University and Chunbuk National University. The obtained results were as follows; 1. The incidence of solitary bone cyst was almost equal in males (52.2%) and in females(42.8%) and the prevalent age of the solitary bone cyst were the second decade (47.8%) and the third decade (21.7%). 2. In the signs and symptoms of solitary bone cyst, pain or tenderness revealed in 17.4%, swelling revealed in 13.0%, pain and swelling revealed in 21.7%, paresthesia revealed in 4.4% and 43.5% were a symptom and the tooth vitality involved in the solitary bone cyst, 76.5% were posterior and 23.5% were either positive or negative. 3. In the location of the solitary bone cyst, 47.8% present posterior region, 21.7% present anterior region, 21.6% present anterior and posterior region, 4.4% present condylar process area. 4. In the hyperostotic border of the solitary bone cyst, 47.8% were seen entirely, 21.8% were seen partially, and 30.4% were not seen. 5. In the change of tooth, 59.1% were loss of the alveolar lamina dura, 13.6% were root resorption 4.55% were tooth displacement, 4.55% were root resorption and tooth displacement. 6. In the change of cortical bone of the solitary bone cyst, 39.1% were intact and 60.9% were thinning and expansion of cortical bone. 7. In the histopathologic findings of 9 cases, 33.3% were thin connective tissue wall, 11.1% were thickened myxo-fibromatous wall, 55.6% were thickened myxofibromatous wall with dysplastic bone formation.

    A simple bone cyst in the proximal humerus of an 18-year-old man was treated by percutaneous ablation with alcohol irrigation. Subsequent involution of the cyst was associated with fatty replacement within the intraosseous defect. A possible relationship between involuting bone cyst and apparent intraosseous lipoma is discussed. (orig.)

  7. A study of the traumatic bone cyst

    International Nuclear Information System (INIS)

    Traumatic bone cyst is a pathologic cavity that is not lined with epithelium. It is, therefore, not a true cyst. It may be a normal variant rather than a disease process. The etiology of the condition is unknown. This condition is occurred widely ranging ages(2 to 75 years), however, most are found during the second decade of life. Radiographically, this condition is radiolucent lesion with well-defined outline, scalloping of superior margins. Cyst enucleation and curettage is the treatment of choice. The authors compared and analyzed the clinicoradiologic features of the five cases of traumatic bone cyst, diagnosed at the Dental college hospital in Chosun University, Kwangju, Korea. The five cases were shown the followed results; 1. 3 cases occurred in second decade of life and no significant sex differences (M:F, 2:3) All cases occurred in mandible. 2. Two patients complained symptoms, but three cases had no symptom with encountering during routine examination. 3. In 3 of 5 cases, teeth vitality existed except one tooth and no checking of teeth vitality in two cases. 4. All cases didn't have any accurate trauma history, but one case was in orthodontic treatment, another case was postextraction site area. 5. Radiologically, 'scalloping appearance' were evident in all cases; in 3 cases, multilocular tendency and only one case seen intact mandibular canal image. 6. Histologically, all section showed bone trabeculae with ballistic activity, 2 cases showed no epithelial lining, and other 2 cases were seen inflammatory cell infiltration in edematous tissue. 7. Surgical intervention (curettage) was that treatment of choice.

  8. Simple bone cyst of the mandible: Report of two cases

    International Nuclear Information System (INIS)

    Despite their names, simple bone cysts are no longer categorized as cysts since they lack an epithelial lining. However, their nature remains controversial. The internal structure is totally radiolucent, sometimes showing multilocular appearance, although the lesion does not contain true septa and the ridges of bone is produced by the scalloping effect. We presented two cases of histopathologically confirmed simple bone cyst. Radiographic features such as multilocular appearance and significant buccal and lingual expansion are not usual findings for simple bone cyst, whereas evident in our presented cases.

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

    Congenital urachal abnormalities are more common in children, but urachal cyst is more frequently seen in adults. Infection within a cyst produces significant symptoms, which may explain the fact that three times as many infected cysts as uninfected urachal cysts are detected in adults. We report here on a case of infected urachal cyst with a fish bone and also the fistular formation between the ileum and urachus in a 63-year-old male with a history of urinary frequency and a tender mass at the lower abdominal quadrant.

    Full Text Available A rare case of aneurysmal bone cyst (ABC located in the coronoid process of the mandible in a 12-year-old girl is presented. Treatment consisted of excision of the lesion through preauricular, submandibular and intraoral approach. An access osteotomy distal to second molar region was required to gain access to medial side of the coronoid process. To our knowledge, this is the third case of an aneurysmal bone cyst of the coronoid process of mandible. While examining a patient with a large expansile intrabony jaw cavity with thin peripheral bone, which is filled with blood without presence of bruit, thrills and pulse pressure, the diagnosis of aneurysmal bone cyst should be on top of the differential diagnosis list. Seventy-four to eighty-five percent of aneurysmal bone cysts of jaws occur in 10-20 years age group. Therefore, a pediatric dentist may be the first person to see such a lesion.

    2007-01-01

    Full Text Available We report a case of multiple extraosseous aneurysmal cysts occurring in the muscle and subcutaneous plane of postero-lateral aspects of the upper right leg. They appeared about 15 months after resection of aneurysmal bone cyst of the upper end of the fibula. They varied in size from 2 cm to 5 cm. Radiologically they were well-defined lesions with central septate areas surrounded by a rim of calcification. Histologically they showed central cystic spaces separated by septa consisting of fibroblasts, osteoclast type of giant cells and reactive woven bone. Thus they showed histological similarity with aneurysmal bone cysts, but did not show any connection with the bone. Only very few examples of aneurysmal cysts of soft tissue had been described in the past one decade and they were reported in various locations including rare sites such as arterial wall and larynx. Recent cytogenetic analyses have shown abnormalities involving 17p11-13 and/or 16q22 in both osseous and extraosseous aneurysmal cysts indicating its probable neoplastic nature. Our case had unique features like multiplicity and occurrence after resection of primary aneurysmal bone cyst of the underlying bone.

    Full Text Available Simple bone cyst represent approximately 3% of all primary bone tumors sampled for biopsy and nearly always occur during the first two decades of life. They are common in metaphyseal region of long bones. Clavicle is rare s ite for this lesion and not many have been reported in literature. We report a case of Histopathologically confirmed Simple bone cyst in a 65 yr s old manual laborer who presented with pain and swelling of long duration. The occurrence of this lesion at unu sual age and at unusual location carries a lot of diagnostic dilemma and various differentials like ABC , Eosinophilic granuloma , and enchondroma were considered only to confirm simple bone cyst on HPE . The symptoms were relieved after resection of lesion. Clavicle was reconstructed with tricortical iliac crest bone graft. At 18th month follow up the patient had no recurrences and had a good functional outcome .

    Full Text Available Aneurysmal bone cysts (ABCs are rare benign bone tumours. Scapula is a very rare location, and the relative literature is sparse. The purpose of this study is to present a case of a giant aggressive scapular aneurysmal bone cyst in a child. A 7-year-old boy presented to our hospital with pain and a palpated mass on the right scapula. Imaging studies (radiographs computed tomography scintigraphy were indicative of aneurysmal bone cyst. We performed curettage and bone grafting after the diagnosis was set by pathological examination through a posterior shoulder approach. Five years later, the patient has only residual signs of the lesion on radiographic control without signs of recurrence.

    1997-03-01

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

    Full Text Available Introduction. Simple bone cyst or unicameral bone cysts are benign osteolytic lesions seen in metadiaphysis of long bones in growing children. Various treatment modalities with variable outcomes have been described in the literature. The case report illustrates the surgical technique of minimally invasive method of treatment. Case Study. A 14-year-old boy was diagnosed as active simple bone cyst proximal humerus with pathological fracture. The patient was treated by minimally invasive percutaneous curettage with titanium elastic nail (TENS and allogenic bone grafting mixed with bone marrow under image intensifier guidance. Results. Pathological fracture was healed and allograft filled in the cavity was well taken up. The patient achieved full range of motion with successful outcome. Conclusion. Minimally invasive percutaneous method using elastic intramedullary nail gives benefit of curettage cyst decompression and stabilization of fracture. Allogenic bone graft fills the cavity and healing of lesion by osteointegration. This method may be considered with advantage of minimally invasive technique in treatment of benign cystic lesions of bone, and the level of evidence was therapeutic level V.

    Soft tissue ganglion cysts are the most common benign tumours of the wrist; their pathogenesis remains controversial. We prospectively screened the radiographic appearance of the wrists of 51 patients presenting to a single surgeon with dorsal wrist ganglions during a one-year period. Postero-anterior and lateral radiographs were systematically performed looking for possible associated intraosseous ganglion cysts. There were 51 dorsal soft tissue ganglion cysts in 51 patients. We detected 29 associated intraosseous ganglia in 24 patients (47%): 16 ganglia in the lunate bone (55%), 5 in the capitate bone, 7 in the scaphoid and 1 in the trapezoid. Mean size of the intraosseous ganglia was 3 mm (range, 2 to 5 mm). This high prevalence of intraosseous ganglia in association with soft tissue ganglia has to our knowledge never been reported previously. A common aetiology for these two types of ganglion cysts may explain this high association rate. PMID:16305077

    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.

    Full Text Available Abstract Background Various treatments for unicameral bone cyst have been proposed. Recent concern focuses on the effectiveness of closed methods. This study evaluated the effectiveness of demineralized bone matrix as a graft material after intramedullary decompression for the treatment of unicameral bone cysts. Methods Between October 2008 and June 2010, twenty-five patients with a unicameral bone cyst were treated with intramedullary decompression followed by grafting of demineralized bone matrix. There were 21 males and 4 female patients with mean age of 11.1 years (range, 3–19 years. The proximal metaphysis of the humerus was affected in 12 patients, the proximal femur in five, the calcaneum in three, the distal femur in two, the tibia in two, and the radius in one. There were 17 active cysts and 8 latent cysts. Radiologic change was evaluated according to a modified Neer classification. Time to healing was defined as the period required achieving cortical thickening on the anteroposterior and lateral plain radiographs, as well as consolidation of the cyst. The patients were followed up for mean period of 23.9 months (range, 15–36 months. Results Nineteen of 25 cysts had completely consolidated after a single procedure. The mean time to healing was 6.6 months (range, 3–12 months. Four had incomplete healing radiographically but had no clinical symptom with enough cortical thickness to prevent fracture. None of these four cysts needed a second intervention until the last follow-up. Two of 25 patients required a second intervention because of cyst recurrence. All of the two had a radiographical healing of cyst after mean of 10 additional months of follow-up. Conclusions A minimal invasive technique including the injection of DBM could serve as an excellent treatment method for unicameral bone cysts.

  5. Extradural Dermoid Cyst of Mastoid Bone: A Case Report

    2012-01-01

    Full Text Available Dermoid cysts of the head and neck are rare congenital benign tumors. According to the literature they represent about seven percent of all dermoids and less than one percent of all intracranial neoplasms. Extradural dermoid cysts are very rare. We report a case of intracranial extradural dermoid cyst of mastoid bone. We believe that this is the second documented extradural dermoid cyst, the first case reported in the literature (Ammirati et al., 2007 was in close relation to the petrous apex but ours is in close relation to mastoid antrum. Hearing loss was the only clinical presentation in this case, while neurological symptoms were the main presenting symptoms in the first reported case. We present our management of this rare case with respect to the clinical, radiological, histopathological, and surgical aspects and conclude that dermoid tumors, though rare, need to be included in differential diagnosis of middle ear lesions.

    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.

    @@ Case Report A 30-year old male patient, admitted in our hospital for a fracture of the upper end of the left humerus in February, 2006, received treatment with curettage of the lesion in combination with an autologous bone graft from the right ilium plus internal fixation. A post-operative pathological examination indicated that there was a simple bone cyst in the area of the fracture, with a satisfactory postoperative recovery.

  8. Radiologic study of the traumatic bone cysts

    International Nuclear Information System (INIS)

    Fifty-two cases of traumatic cysts in 50 patients were analysed clinically and radiologically. The obtained results were as follows; 1. Women showed a slightly higher incidence than did men (56% of patients) and the average age proved to be 18.6 years. 2. The majority of the cases were asymptomatic, being detected incidentally, and over the half of the cases occurred in the mandibular symphyseal region. 3. All cases were unilocular and the largest diameter of the lesions varied from 1 to 10 cm, mean 3 cm. 4. Some degree of marginal condensation was present in 28 cases and 23 cases presented pencil-sketch appearance. 5. Many anatomical cortical plates (especially, mandibular inferior cortex and lamina dura) consisted of the margin of the lesions partly. 6. Erosive change of the mandibular inferior cortex was caused by 12 cysts, but cortical expansion only by 3 cysts including 2 cases of buccal expansion. 7. The lesion enveloped the roots of the adjacent teeth in 27 cases and scalloping was present between roots in 17 cases. 8. Lamina dura of the teeth was destroyed by only 1 cyst, and in 1 case resorption was noticed. But there was no divergence of the roots of teeth

  9. Aneurysmal bone cyst: revision of different techniques in imaging diagnostic

    International Nuclear Information System (INIS)

    We study simple radiology, conventional tomography, computed tomography and angiography in 8 cases of aneurysmal bone cyst for the purpose of assessing the utility of these diagnostic techniques. Our results, in agreement with those in the literature, indicate that the presence of a generally well-defined lytic, insufflated lesion containing septi should suggest this disorder. (Author)

  10. Contrast medium injected into juvenile bone cysts to analyze interior morphology and guide intracavity corticosteroid treatment

    International Nuclear Information System (INIS)

    In connection with treating juvenile bone cysts with intracavital corticosteroid injections, the interior cyst anatomy was analyzed at cystography in 13 children aged 4 to 15 years. Only 4 children had a true unicameral cyst; the others had 2 or more cysts or had compartments with free or restricted communication to the main cyst. Cysts and compartments which had not been reached by steroids may continue to grow. Optimum treatment may therefore require injections at different sites guided by cystography. Neither conventional criteria of cyst activity nor repeated bone scintigraphy 3 months after treatment could predict whether the treatment would lead to final healing. (orig.)

    Cysts of the mandibular condyle are rare and can be difficult to diagnose and treat. Clinically, a simple bone cyst is asymptomatic and often discovered incidentally on routine radiographic examination. This report shows an atypical simple bone cyst occurring in the mandibular condyle showing recurrence after surgical curettage. Radiologically, this lesion involving the mandibular condyle should be distinguished from other similar lesions such as a chondriome, a central giant cell granuloma, and an aneurysmal bone cyst. Radiographic assessment was useful for forecasting the prognosis of a simple bone cyst. Possible reasons for the recurrence were discussed radiographically.

    Aneurysmal bone cyst is a locally aggressive benign tumor accounting for 3 % of all benign bone tumors. It most commonly arises from ends of long bones and relatively rare in flat bones. Clavicle is a very rare site for bone tumors with secondaries more common than primaries. Very few cases of aneurysmal bone cyst have been reported in literature. We hereby report interesting and a rare case of aneurysmal bone cyst of medial end of clavicle in a eight year old lady which was treated with extended curettage and calcium sulfate bone grafting.

  13. Enlarging bilateral femoral condylar bone cysts without scintigraphic uptake in a yearling foal

    International Nuclear Information System (INIS)

    Bilateral subchondral bone cysts of the femoral condyles were diagnosed by conventional radiography in a 14 month old Appaloosa colt. Surgical debridement was performed, and over the next 18 months the appearance of the cysts was evaluated with radiography and bone scintigraphy. On the preoperative scintigrams, increased radiopharmaceutical uptake was associated with the cysts. Despite continued radiographic enlargement, the cysts did not demonstrate increased radiopharmaceutical uptake post-operatively

  14. Familial early onset sarcoidosis with bone cysts and erosions

    International Nuclear Information System (INIS)

    Early onset sarcoidosis is a granulomatous disease which is characterized by synovitis, polyarthritis, skin and eye involvement. We report the skeletal features of one patient with a family history and clinical symptoms suggestive of early onset sarcoidosis (EOS) which was confirmed by skin biopsy. Radiographs reveal postarthritic deformities of the MCP joints, contractures, a coarsened trabecular pattern at the PIP joints and small bone cysts resembling osteitis cystoides multiplex. Similar lesions were described in radiographs of the older sister and an uncle of our patient. This is the first report demonstrating bone cysts and erosions which could be a diagnostic feature in this rare disease and may help to differentiate other rheumatoid disorders. (orig.)

    Aneurysmal bone cysts (ABC) are benign but locally aggressive osseous lesions characterized by blood-filled cystic cavities that account for 1-2% of all bone tumors. While pain remains the most common presenting symptom of spinal ABC, extensive anterior column involvement can result in vertebral fractures, spinal instability, and neurological deficits from compression of neural elements. An exceedingly rare case of thoracic ABC presenting as acute paraparesis in a 21-year-old pregnant woman, that was successfully treated with urgent surgical decompression and stabilization, is reported, with discussion of management strategies and review of the pertinent literature.

    2003-01-01

    A 14 year-old boy developed a tibial aneurysmal bone cyst (ABC) following a closed tibia fracture. The tumor formed in a site remote from the fracture and was not radiographically apparent until one year following the traumatic event. Most ABC's present due to fracture or pain, but this lesion was discovered during routine follow up films of the tibial shaft fracture. This case lends support to the debated theory that ABC's are reactive bone lesions and provides a rare radiographic glimpse at...

    A unicameral bone cyst (UBC) may require surgery if its location increases the risk for pathologic fracture, or if it is painful or increasing in size. This case series demonstrates that curettage and grafting with a bone graft substitute alone can result in healing of the UBC. Three children with UBC and pathological fractures were treated with curettage and grafting using bone graft substitute beta-tricalcium phosphate granules (CHRONOS). All three went on to full union of the fracture and ...

  19. Aneurysmal bone cyst: value of MR imaging and conventional radiography

    International Nuclear Information System (INIS)

    Our objective was to investigate the accuracy and the diagnostic value of different imaging features of primary aneurysmal bone cysts (ABC) in conventional radiographs and MRI. Conventional radiographs and MR images of 34 patients with a suspected aneurysmal bone cyst were reevaluated by six independent radiologists in a blinded fashion. Morphological features, MR signal characteristics, and contrast enhancement patterns were assessed. Diagnoses were correlated with histology. Sensitivity and specificity of the different imaging findings for each imaging technique were calculated. In 24 patients ABC was histologically proven. In 10 cases diagnoses other than ABC were established. Conventional radiography and MRI each demonstrated a sensitivity of 76.4 and 77.8% with a specificity of 55.0 and 66.7%, respectively. With combined use of both imaging modalities sensitivity and specificity increased to 82.6 and 70%, respectively. The ABC was significantly more often seen as circumscribed lesion with bone expansion, lobulation, septa, and pathological cortical bone reaction than those cases with different diagnoses. Septal contrast enhancement proved to be a useful MR imaging finding in suspected ABC. The combined use of conventional radiographs and MRI revealed the highest sensitivity in the diagnosis of ABC in relation to histology. Magnetic resonance imaging provides improved diagnostic specificity and valuable information on soft tissue changes. (orig.)

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

  2. Imaging diagnosis of the juxta-articular bone cyst

    International Nuclear Information System (INIS)

    Objective: To investigate the imaging features of the juxta-articular bone cyst(intra- osseous ganglia). Methods: The imaging findings of 54 cases histopathologically confirmed were studied retrospectively. X-ray, CT, and MRI were performed in 46 eases, 30 cases, and 14 cases, respectively. Results: Of the 54 cases, 27 arised from the ankle (including multiple lesions), 16 from the knee joint, 7 from the hip joint, 1 from the proximate end of the humerus, ulna, trapezium bone, the first phalange in each, and 1 from the talus and the distal end of the tibia. There were 43 cases (44 lesions) in the ankle and knee joints, with 29 (65.9%) lesions located in the medial articular surface. Fifty-four cases had thinning sclerotic rim, showing a unilocular round osteolytic appearance in 44 cases and a multiloculated-cystic appearance with septa in 10 cases. Discontinuous articular surface were seen in 15 cases, reticular surface collapse in 1, gas density in 3 and fluid-fluid plane in 1. (1) On x-ray films, 46 cases (47 lesions) with well-defined sclerotic rim revealed round, arch or irregular lyric areas at the adjacent articular surface. The fissures were found at the adjacent articular surface in 6 lesions. No joint spaces were abnormal. (2)On CT, 30 cases with sclerotic rim showed round in 19 lesions, arch in 3, and irregular in 8. The fissures were seen at the adjacent articular surface in 14 lesions. The density showed homogeneous in 27 lesions, and gas existed in 3. (3) Fourteen cases (15 lesions)showed hypointense to isointense signal on MR T1WI and hyperintense signal on T2WI. Fluid-fluid plane was found in 1 case. The fissures were observed at the adjacent articular surface in 8 lesions. 7 cases showed swelling soft tissue. Conclusion: The characteristic locations combined with the typical imaging features may suggest the diagnosis of jaxta-articular bone cyst. (authors)

    Full Text Available The purpose. To examine the results of the treatment of children with aneurysmal cyst of the clavicle. Material and methods. The results of examination and treatment of patients aged 16 and 17 years with a diagnosis of aneurysmal cyst of the clavicle. All patients underwent surgical treatment with the ABC stage delimitation. We used a surgical technique, which consists in open removement of the abnormal tissue with replacement of the bone defect with bone-plastic material or autogenous bone from the iliac crest. Conclusions. The method of treatment of aneurysmal bone cyst of the clavicle must be individualized depending on the location, aggressiveness and extent of the lesion. The use bone-plastic material or autogenous bone from the iliac crest restore the structural integrity of a compromised clavicle gives good results in the observation period of up to 2 years.

    Full Text Available Abstract We report a case of a symptomatic unicameral (simple bone cyst of the lunate in a 42-year- old woman. The lesion was treated with curettage and cancellous autogenous iliac bone grafting. At five years of follow-up the wrist was pain free, there were no limitations of motion, and the radiographs showed complete obliteration of the cavity. To the best of our knowledge, no other unicameral bone cyst of the lunate has been reported in an adult. Cysts with significant cavities at the carpal bones in an adult should be approached cautiously, as they may require early curettage and bone grafting for healing, before collapse and degenerative changes occur.

  8. JAW CYSTS AND GUIDED BONE REGENERATION (a late complication after enucleation

    Full Text Available Maxillary jaw bone possesses a high regenerative capacity. Yet sometimes the defects enucleation of jaw cysts leaves may regenerate only partially or not at all. For this reason some researchers advise treatment of the residual cavities after cystectomy using bone regeneration stimulation methods. We report a case of an atypical complication after enucleation of a maxillary cyst manifesting itself eight years after the initial treatment. The symptoms the patient reported were at first periodic sweating on the left sides of face and head. This was followed by a piercing pain in the left palpebral fissure radiating to the middle of the palate and felt in the left cheekbone, left eye and left supraorbital ridge. The patient has a history of maxillary cysts recurring three times and of three operations she had 20, 12 and 8 years previously. The multiple recurrences of the cysts after their enucleation indicates poor regenerative capacity of the body which resulted in the formation of cicatricial tissue. It is most probably this tissue that was responsible for the disruption of the nerve conduction capacity which can account for the reported symptoms. We filled the cavity with bone graft material which boosted the bone structure regeneration. Although maxillary jaws possess high regenerative capacity we advise the use of guided bone regeneration in cases of large bone defects that usually occur after enucleation of jaw cysts.

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

  11. Imaging study of ossifying fibroma with associated aneurysmal bone cyst in the paranasal sinus

    International Nuclear Information System (INIS)

    Objective: To determine the CT and MR imaging features of ossifying fibroma with aneurysmal bone cyst of the paranasal sinus. Materials and methods: We retrospectively reviewed 15 patients with histopathology-proven ossifying fibromas with aneurysmal bone cysts in the paranasal sinus. All 15 patients underwent CT and MR imaging. The following imaging features were reviewed: location, shape, margin, CT findings, and MR imaging appearances and time-intensity curve of dynamic contrast-enhanced MR imaging. Results: Ossifying fibromas occurred in the maxillary sinus in one patient, sphenoid sinus in 2, frontal sinus in 3, frontoethmoid sinuses in 3, and ethmoid sinus in 6 patients. Ossifying fibromas showed an elliptic-shape and aneurysmal bone cysts revealed a multicystic appearance, with well-demarcated margins. On unenhanced CT, ossifying fibromas appeared isodense to gray matter with scattered calcifications in nine, ground-glass appearance in 6 patients and aneurysmal bone cysts showed mixed density. Ossifying fibromas appeared isointense to gray matter in 12 and slightly hypointense in three patients on T1-weighted images, and isointense in 4 and hypointense in eleven patients on T2-weighted images, with moderate or marked enhancement after administration of contrast material. The time-intensity curves of eight ossifying fibromas exhibited a rapidly enhancing and rapid washout pattern. The intracystic components of aneurysmal bone cysts showed heterogeneous signal intensity on MR images, with fluid–fluid levels identified clearly by T2-weighted images, without enhancement. The periphery and septa of aneurysmal bone cysts appeared isointense on MR images, with marked enhancement. Conclusions: Fluid–fluid levels within an elliptic-shape mass with scattered calcifications or ground-glass appearance is highly suggestive of this complicated entity in the paranasal sinus.

    To determine the efficacy of percutaneous sclerotherapy in the treatment of aneurysmal bone cysts. Seventeen patients (7 girls, 10 boys) with aneurysmal bone cysts were treated by the percutaneous approach with Ethibloc (n=14) and histoacryl glue (n=3) in our institution between January 1994 and June 2000. The cysts were located in the extremities (n=6), pelvis (n=2), spine (n=2), mandible (n=5), rib (n=1) and sphenoid bone (n=1). Percutaneous sclerotherapy was performed with fluoroscopic and/or computed tomographic guidance under general anesthesia. Clinical and imaging follow-up lasted from 24 months to 9 years and 6 months (mean: 57.3 months). The results were quantified as: excellent (residual cyst less than 20% of the initial involvement), satisfactory (residual cyst 30-50%), unsatisfactory (residual cyst more than 50%). The age of the patients ranged from 4 years and 6 months to 15 years and 8 months (mean: 11 years and 2 months). In nine patients, the therapeutic procedure was repeated 2-5 times. Excellent regression was observed in 16 (94%), satisfactory results in 1 (6%). There was no failure (unsatisfactory result or no response to treatment) in this reported series. The complications were minor and included: local inflammatory reaction (n=2), small blister (n=1), and leakage (n=1). Relief of symptoms was achieved in all patients. No recurrence was noted during follow-up. Percutaneous sclerotherapy of aneurysmal bone cysts with Ethibloc is safe and effective. It is an important alternative to surgery, especially when surgery is technically impossible or not recommended in high-risk patients. (orig.)

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

    Full Text Available Aneurysmal bone cyst of the spine was first described by Jaffè et al in 1942 . An aneurysmal bone cyst (ABC is a non - neoplastic expansile and locally destructive highly vascular bone lesion characterized by channels or spaces filled with blood and separat ed by fibrous septa. It usually involves long bones. Its occurrence in spine is rare , and usually involves posterior elements , while involvement of body is very rare. MR I and CT are the imaging modalities of choice in the diagnosis of bone cysts in the spine . Although regarded as benign tumors , ABCs can be locally aggressive , causing profound destruction of their encasing bones and pathological fractures , as well as compression of adjacent vital tissues from their rapid expansion. For this reason , ABCs o f the spine , due to their close proximity to the spinal cord and nerve roots , warrant special attention and present a unique clinical challenge. We are reporting this case with ABC of thoracic spine involvement which was mainly involving the body.

  19. Selective arterial embolization of 36 aneurysmal bone cysts of the skeleton with N-2-butyl cyanoacrylate

    International Nuclear Information System (INIS)

    Aneurysmal bone cyst (ABC) is a lytic benign bone lesion representing about 1% of all primary bone tumors. The lesion causes pain and swelling, which are generally present for less than 3 months. From April 2003 to April 2008 36 patients affected by aneurysmal bone cysts were treated by selective arterial embolization with N-2-butyl cyanoacrylate. The study population comprised 20 male and 16 female patients with an age range of 3.3-60.8 years. Nine lesions were localized in the appendicular skeleton (1 in the upper and 8 in the lower limb), 4 in the thoracic cage (1 rib lesion and 3 scapular lesions), 17 in the pelvis and 6 in the spine (1 thoracic and 5 sacral localizations). A total of 55 embolizations were performed: in 22 cases (61%) only one embolization was needed, whilst two embolizations were necessary in 9 cases (25%) and 3 in the remaining 5 patients (14%). The treatment was effective in 32 patients (94%): follow-up was 0.9-5 years. In one patient, previously surgically treated, only the cyanoacrylate embolization turned out to be useful for healing the lesion. Another 7 patients underwent surgery during the study period. In the 55 procedures we performed we had 3 complications (5%): 2 cases of skin necrosis and 1 of transient paresis. Arterial embolization with cyanoacrylate may be the treatment of choice for aneurysmal bone cysts. Embolization is a less invasive, lower cost, simpler procedure than surgery and is easily repeatable. (orig.)

  1. Simple bone cysts in children treated with intracystic fibrin sealant injection

    Institute of Scientific and Technical Information of China (English)

    2006-01-01

    @@ Simple bone cyst (SBC), also known as a unicameral or solitary cyst, is a benign fluid-filled cavity found primarily at the proximal ends of long bones in children. Treatment is warranted if the pain or a pathologic fracture occurs or if a child is at risk of pathologic fractures. The spectrum of treatments proposed for SBC management ranges from simple Kirschner wire drill-hole, resection or curettage with or without bone grafting to using a cannulated screw for continuous decompression, steroid injection and the latest experience of the use of percutaneous autologous marrow grafting.1-4 However, clinical practice of these treatments is limited because of their unsatisfactory effect and possible compli- cations.

    The aim of this paper is to evaluate the frequency of limb shortening in the course of solitary bone cyst treatment. The correlation between the mode of treatment as well as the occurrence of pathological fracture, cyst location, volume, and locularity were examined. A retrospective analysis was carried out on 135 patients where 80 underwent curettage and bone grafting and 55 were administered methylprednisolone injection with a mean time to follow-up of 12 years. Based on clinical and radiological evaluation, limb shortening was found in ten patients when the data before and after treatment was compared. Limb shortening ranging from 1 to 5 cm during the course of the treatment was observed: six in humerus, two in femur, two in tibia. Those with epiphyseal changes, magnetic resonance imaging to evaluate the degree of growth plate damage was performed. Patients with and without limb shortening did not differ statistically regarding the applied method of treatment. The cyst volume was significantly larger in the group of patients with limb shortening when compared to the group of patients with no limb shortening. In patients treated with curettage and bone grafting, the mode of treatment does not increase the frequency of occurrence of iatrogenic limb shortening. In patients with limb shortening, a statistically significant larger volume of the cyst was observed. (orig.)

    Full Text Available Introduction. Aneurysmal bone cyst is a benign bone lesion composed of blood filled cystic cavities lined by fibrous septa. Its malignant transformation of is a rare event. Case report. We report a case of a lesion in the second metatarsal bone in a 29-year-old male, presented as a slight swelling of the right foot. After the curettage had been done, the diagnosis of aneurysmal bone cyst was made but the recurrence occurred 4 years later. The biopsy of the recurrent tumor showed compact neoplastic tissue consistent with diagnosis of giant cell tumor with malignancy. The malignant component was recognized as a high grade sarcoma with osteoid production. A tumor mass with the whole II metatarsal bone was extirpated and a resected part of fibula was transplanted. A year later, another recurrence occurred, an amputation was performed and a teleangiectatic osteosarcoma with ingvinal lymph nodes metastases was diagnosed. No other tumor mass was confirmed, either clinically or by imaging techniques at the time of his third operation. He died 4 months later with multiple pulmonary metastases. Conclusion. We emphasize the importance of team work in order to achieve the accurate diagnosis, highlighting careful radiological examinations, good sampling and awareness of unusual cases in bone tumor pathology.

    Introduction: Intraosseous ganglions, although share same pathology as the soft tissue ganglions are rare entities, further rare in carpals. Cases of intraosseous ganglions are reported in literature mostly in lower limbs and lunate among carpals, with treatment options ranging from curettage and grafting to calcium phosphate cement injection and finally to arthroscopic treatment. Case report: Here, we present a case of 2 years follow up of 40 years old female with nonspecific clinical finding of wrist and slight limitation of restriction of motion, diagnosed as intraosseous ganglion cyst of scaphoid. This case was treated with curettage and bone grafting having excellent results with visual and analog pain scores reduced from 68 to 11 and range of motion was 90° extension to 80° flexion and full grip strength. Conclusion: Intraosseous ganglion cyst should be considered in differential diagnosis of chronic dull wrist pain because they produce disabling symptoms which ceases once adequately treated by curettage and bone grafting.

    A 9-year-old girl visited our hospital, complaining of a rapid-growing and rigid swelling on the left posterior mandibular area. Panoramic radiograph showed a moderately defined multilocular honeycomb appearance involving the left mandibular body. CT scan revealed an expansile, multilocular osteolytic lesion and multiple fluid levels within cystic spaces. Bone scan demonstrated increased radiotracer uptake and angiography showed a highly vascularized lesion. The lesion was suspected as aneurysmal bone cyst (ABC) and preoperative embolization was performed, which minimize the extent of operation and the surgical complication. The lesion was treated by surgical curettage and lateral decortication with repositioning. No additional treatment such as a surgical reconstruction or bone graft was needed. Early diagnosis of ABC is very important and appropriate treatment should be performed considering several factors such as age, surgical complication, and possibility of recurrence.

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

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

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

    Full Text Available The authors analyze the design of a method for automatized evaluation of parameters in orthopantomographic images capturing pathological tissues developed in human jaw bones. The main problem affecting the applied medical diagnostic procedures consists in low repeatability of the performed evaluation. This condition is caused by two aspects, namely subjective approach of the involved medical specialists and the related exclusion of image processing instruments from the evaluation scheme. The paper contains a description of the utilized database containing images of cystic jaw bones; this description is further complemented with appropriate schematic repre¬sentation. Moreover, the authors present the results of fast automatized segmentation realized via the live-wire method and compare the obtained data with the results provided by other segmentation techniques. The shape parameters and the basic statistical quantities related to the distribution of intensities in the segmented areas are selected. The evaluation results are provided in the final section of the study; the authors correlate these values with the subjective assessment carried out by radiologists. Interestingly, the paper also comprises a discussion presenting the possibility of using selected parameters or their combinations to execute automatic classification of cysts and osteonecrosis. In this context, a comparison of various classifiers is performed, including the Decision Tree, Naive Bayes, Neural Network, k-NN, SVM, and LDA classifica¬tion tools. Within this comparison, the highest degree of accuracy (85% on the average can be attributed to the Decision Tree, Naive Bayes, and Neural Network classifiers

    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 ob...

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

    Aneurysmal bone cyst is a benign, cystic lesion of bone composed of blood-filled spaces separated by fibrous septa. Relatively few cases of aneurysmal bone cyst have been cytogenetically characterized, yet abnormalities of the short arm of chromosome 17 appear to be recurrent. In this study, conventional cytogenetic analysis of 43 aneurysmal bone cyst specimens from 38 patients over a 12-year period revealed clonal chromosomal abnormalities in 12 specimens. Karyotypic anomalies of 17p, including a complex translocation and inversion, were identified in eight of these 12 specimens. In an effort to further define the aberrant 17p breakpoint, fluorescence in situ hybridization (FISH) analyses were performed using a series of probe combinations spanning a 5.1 Mb region between the TP53 (17p13.1) and Miller-Dieker lissencephaly syndrome (17p13.3) gene loci. These studies revealed the critical breakpoint locus at 17p13.2, flanked proximally by an RP11-46I8, RP11-333E1, and RP11-457I18 bacterial artificial chromosome (BAC) probe cocktail and distally by an RP11-198F11 and RP11-115H24 BAC and RP5-1050D4 P1 artificial chromosome (PAC) probe cocktail. Overall, abnormalities of the 17p13.2 locus were identified by metaphase and/or interphase cell FISH analysis in 22 of 35 (63%) aneurysmal bone cyst specimens examined including 26 karyotypically normal specimens. These cytogenetic and molecular cytogenetic findings expand our knowledge of chromosomal alterations in aneurysmal bone cyst, further localize the critically involved 17p breakpoint, and provide an alternative approach (ie FISH) for detecting 17p abnormalities in nondividing cells of aneurysmal bone cysts. The latter could potentially be utilized as an adjunct in diagnostically challenging cases. PMID:15044915

    Unicameral bone cysts can predispose patients to pathologic fracture and deformities of growth. Treatment options vary from continuous decompression with transcortical placement of a cannulated screw to percutaneous aspiration and injection of medical-grade calcium sulfate. From 2005 to 2007, we treated 22 patients with unicameral bone cysts using aspiration and injection of calcium sulfate. Three patients experienced acute laryngospasm and one patient developed tachyarrhythmia, temporarily, associated with injection of calcium sulfate. All reactions occurred in patients under age 18 without predisposing risk factors and resolved spontaneously with supportive care. Although the mechanism is unclear, we hypothesize that these reactions are either due to the nociceptive stimulus of the calcium sulfate injection or a systemic calcium bolus. Clinicians using this product for this indication should be aware that such reactions may occur. We suggest endotracheal intubation and communication to the anesthesiologist about the time of the injection in preparation for these idiopathic responses. Further research is necessary to determine exactly how this reaction occurs and how it can be avoided. PMID:19223954

    The reconstructive options for large expansive cystic lesion affecting the jaws are many. The first stage of treatment may involve enucleation or marsupialization of the cyst. Attempted reconstruction of large osseous defects arising from the destruction of local tissue can present formidable challenges. The literature reports the use of bone grafts, free tissue transfer, bone morphogenic protein and reconstruction plates to assist in the healing and rehabilitation process. The management of huge mandibular cysts needs to take into account the preservation of existing intact structures, removal of the pathology and the reconstructive objectives which focus both on aesthetic and functional rehabilitation. The planning and execution of such treatment requires not only the compliance of the patient and family but also their assent as customers with a voice in determining their surgical destiny. The authors would like to report a unique case of a huge solitary bone cyst that had reduced the ramus, angle and part of the body of one side of the mandible to a pencil-thin-like strut of bone. A combination of decompression through marsupialization, serial packing, and the fabrication of a custom made obturator facilitated the regeneration of the myo-osseous components of the masticatory unit of this patient. Serial CT scans showed evidence of concurrent periosteal and endosteal bone formation and, quite elegantly, the regeneration of the first branchial arch components of the right myo-osseous masticatory complex. The microenvironmental factors that may have favored regeneration of these complex structures are discussed. PMID:27408457

    Full Text Available We are presenting a case of cervical (C4 aneurysmal bone cyst in a 13-year-old girl, came to the outpatient department with neck pain and stiffness since 6 months and normal neurology. We did an en bloc excision of locally aggressive tumor through anterior plus posterior approach and stabilization by lateral mass screw fixation and anterior cervical instrumentation. Involvement of several adjacent cervical vertebrae by an aneurysmal bone cyst is rare, and conventional treatment with curettage and bone grafting is most likely to carry a high rate of recurrence and spinal instability. We recommend complete excision of the tumor and instrumentation in a single stage to avoid instability.

    愈。相对其它治疗方法,此方法操作简单,损伤小,可以作为治疗单纯骨囊肿的首选方法。%Objective To study and summarize the curative effects of intralesional injection of methylprednisolone for the treatment of the bone cysts in different parts of the body. Methods 33 patients with bone cysts of intact data were adopted from May 2007 to July 2012, who were treated with intracapsular injection of methylprednisolone. There were 23 males and 10 females, whose mean age was 12.3 years old ( range;5-28 years ). All patients were followed up for a mean period of 31.3 months ( range;3-53 months ). The lesions of 10 cases were situated in the proximal femur, 1 case in the shaft of femur, 1 case in the distal ifbula, 2 cases in the ilium and 19 cases in the proximal humerus. 11 patients with pathological fractures were immobilized for 1-2 months, who received treatment when the fractures were healed. Before the treatment, 4 patients who were treated with curettage and bone graft reoccurred postoperatively. 2 of them were treated with curettage, bone graft and internal ifxation with steel plates. Before the treatment, routine aspiration biopsy was performed on all the patients, and hormone therapy was carried out when bone cysts were conifrmed. Before the treatment, venous general anesthesia was used. Under the guide of“C”-arm, 2 medullo-puncture needles were introduced into both sides of the lesions to scrape the bone wall and destroy the cyst membrane. The lesions were repeatedly washed by normal saline, and contrast medium was injected. When the lesions were in good comditions, contrast medium would be rushed. The volume of 100-200 mg methylprednisolone was determined by the size of the cystic cavity. The puncture needle was pressed for 3 minutes to prevent the hormonal exudation and compress the wound bandage. Results 30 patients were injected with different amounts of hormones for a mean of 2.5 times ( range;2-4 times ), and the

    The following review investigates the term and concept of the globulomaxillary cyst as a correct clinico-pathological diagnosis to describe a so-called fissural cyst said to be caused by epithelial entrapment between the nasal and maxillary process. After analyzing the available literature it has to be concluded that neither from an embryologic nor from a clinical or pathohistological standpoint the term globulomaxillary cyst represents a real entity by itself. Therefore, globulomaxillary cysts have to be diagnosed alternatively after a thorough clinical, radiological and histological examination as other odontogenic cysts like dentigerous cysts or odontogenic keratocysts, odontogenic tumors like ameloblastoma, central giant cell tumors, solitary bone cysts, etc. PMID:16708524

  12. THYROGLOSSAL DUCT CYST

    Full Text Available The thyroglossal duct cyst (TDC results from a failure in obliterating the embryogenic duct produced during thyroid migration and it represents the most common type of developmental cyst encountered in the neck region. Ectopic thyroid tissue neoplasias are rare, and even rarer when associated with the TDC. Methods: During the period 1998-2008, in the First Surgical Clinic, University Hospital “St. Spiridon” Iasi, 14 patients with thyroglossal duct cyst were diagnosed and treated. All records were reviewed for age and sex, diagnostic methods, sizes, surgical management and recurrences. Results: All patients with thyroglossal duct cysts are described as midline cysts of the neck. The ratio females/males was 6/1 with mean age 37.6 years (13-60 years. One case was with an external fistula. The treatment performed was a variant of Sistrunk’s procedure in which the thyroglossal tract was excised to a variable extent, but in all cases with central hyoidectomy. The size of the cyst ranged from 1.2 to 4 cm (mean 2.6 cm. Postoperative course was unventful in all cases. No recurrence was recorded in this series. We describe a case, a 19 years old female with thyroid papillary carcinoma evolving from a TDC. The literature is reviewed. Conclusion: The standard surgical approach to TDC is Sistrunk's operation with low recurrence rates. Malignancy within a thyroglossal duct cyst is very rare but should be included in the differential diagnosis of a neck mass. In such cases total thyroidectomy with removal of the tumour of thyroglossal duct and the body of the hyoid bone are recommended – because the carcinoma may be multifocal and because a lymphatic invasion of the thyroid may take place – in order to ensure a correct follow-up.

    Retrorectal cystic hamartomas (tailgut cysts) are rare congenital lesions thought to arise from remnants of the embryonic postanal gut. They predominantly occur as asymptomatic retrorectal multicystic masses in women. The treatment of choice is by complete surgical excision. The most important complications of these cysts are infection with a secondary fistula and malignant degeneration. The differential diagnosis includes a wide variety of conditions that occur in the retrorectal space. In this article, 3 cases showing different surgical technical aspects of treatment are presented. In addition, the aetiopathogenic features and histopathological appearance, clinical presentation and complications, imaging features and differential diagnosis of tailgut cysts are described.

    Glandular odontogenic cyst (GOC) is a rare and uncommon jaw bone cyst of odontogenic origin described in 1987 by Gardener et al. as a distinct entity. It is a cyst having an unpredictable, potentially aggressive behavior, and has the propensity to grow in large size with relatively high recurrence rate. It poses a diagnostic challenge as it can be clinically and histopathologically confused with lateral periodontal cyst, botryoid odontogenic cyst, radicular and residual cysts with mucous metaplasia, and low-grade mucoepidermoid carcinoma. The present case report describes GOC in both male and female patients with intra-oral swelling following extraction of 36 and 46, respectively. Careful histopathological examination is needed to diagnose GOC, and a careful long-term follow-up is advocated. PMID:27134453

    Full Text Available Botryoid odontogenic cyst (BOC is considered to be a polycystic variant of the lateral periodontal cyst (LPC as the specimen resembled a cluster of grapes. It is a non-inflammatory odontogenic cyst. The BOCs can be unicystic or multicystic. These cysts have potential to extend in the bone and become multilocular and they have a high recurrence rate. Till now, only 73 cases of BOC have been reported. The pathogenesis of BOC is still debatable. We review different pathogenesis proposed for BOC and discuss a rare case of BOC developing from lining of an abnormally large LPC which showed aggressive behaviour in terms of growth and size.

    Full Text Available Nasolabial cysts are painless, submucosal, non-odontogenic jaw cysts presenting as soft tissue swellings in the maxillary anterior mucolabial fold lateral to midline, leading to elevation of nasal ala. Present case documents bilateral nasolabial cysts in a 69-year-old Asian female patient. In the present case, extraoral swelling of maxillary lip and elevation of nasal ala was observed on right side of the face. Intraorally, soft and fluctuant bilateral cysts were observed. Straw-colored fluid was aspirated from the right cyst. Radiographically, erosion of bone in a "cupping" fashion was observed in the region of left cyst. The cysts were enucleated using intraoral approach. Histopathology of the right-sided cyst revealed a cystic cavity lined by stratified squamous cells along with a few mucosal cells. At few places, stratified squamous and pseudostratified columnar epithelia with many cilia and goblet cells were also evident. Capsule was loosely arranged with fibrous tissue and chronic inflammatory infiltrate. Left-sided cystic specimen showed two or more layered stratified squamous lining epithelium with thin capsule. Diagnosis of bilateral nasolabial/nasoalveolar cysts was confirmed.

OBJETIVO: Descrever as características clínico-cirúrgicas e radiográficas dos cistos ósseos traumáticos. MATERIAL E MÉTODO: Estudo de caráter retrospectivo dos pacientes diagnosticados com cisto ósseo traumático em um serviço de patologia oral no período de 1992 a 2007. Informações referentes às características clínicas, radiográficas e cirúrgicas foram coletadas. RESULTADOS: Vinte e seis casos de cisto ósseo traumático foram diagnosticados no período de 15 anos, 17 pertencentes ao sexo masculino e 09 ao sexo feminino. A maioria dos pacientes afetados pertencia às duas primeiras décadas de vida, não relatava sintomatologia dolorosa, bem como história de trauma na região da lesão. O padrão multilocular foi observado em apenas sete casos, dando às lesões uma aparência radiográfica tumoral. A presença de ar no interior da cavidade patológica foi relatada em aproximadamente 70% dos casos, sendo rara a presença de conteúdo serossanguíneo e seroso. CONCLUSÃO: A maior prevalência de casos em pacientes jovens, a infrequente história de trauma e o pequeno número de lesões com conteúdo serossanguíneo refletem a necessidade de se discutir a real patogênese do cisto ósseo traumático.The traumatic bone cyst is characterized by the presence of an asymptomatic sinus devoid of epithelial lining, which is rarely found in the jaws.

We retrospectively reviewed the ultrasonographic findings in 31 patients with pathologically proven cysts of the thyloglossal duct. Assessment involve the following variables: relationship to the hyoid bone,location,shape,size,margin,internal echogenicity,the presence of septa,solid component,and thickness of the cystic wall. The echogenicity of cystic contents was evaluated in 23 cysts for which surgical or aspiration biopsy reports were available.Cysts were closely attached to the hyoid bone in 30 cases (97%). Their location was infrahyoid in 14 cases, hyoid in 11, and surprahyoid in six; and midline in 18, both midline and of-midline in nine, and off-midline in four. A triangular shape was seen in 15 cases ,a round or oval shape in 12, and a lobulated shape in three. Their diameter varied from 1 to 3.8 (mean,2) cm, while internal echogenicity was hypoechoic in 12 cases, anechoic in ten, and isoechoic in nine. Septations were noted in six cases, and a solid component in two.The cystic wall was less than 1mm in six. Among 23 cases, the cystic contents were mucous in 18, serous in three , and purulent in two. The echogenicity of cysts with mucous content varied,while serous or purolent cysts were isoechoic. The characteristic sonographic finding of cyst of the thyroglossal duct is a centrally located triangular neck cyst, closely related to the hyoid bone.

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

    Full Text Available Thyroglossal duct cyst is the most common cause of midline congenital swelling in the neck. Classically, it presents as an asymptomatic midline swelling below the hyoid bone that moves with deglutination and protrusion of the tongue. Sometimes thyroglossal duct cyst presents atypical posing a diagnostic challenge. A sublingual location of thyroglossal duct cyst is rare, and differs quite remarkably in presentation from the classical thyroglossal duct cyst. We describe here the case of a young boy who presented with episodes of postural dyspnea due to elevation of the tongue which was secondary to huge sublingual swelling. Surgical decompression of the lesion was planned on an emergency basis with feasible preoperative workup. The aim of this case report is to highlight the unique presentation and a varied approach in the management of an unusually located sublingual thyroglossal duct cyst. Sublingual/intralingual thyroglossal duct cyst needs to be analyzed in a larger study population for establishing definitive management protocols.

    2011-01-01

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

    On the basis of the studies listed in the bibliography, this dissertation reports on the pathology, clinical symptoms and radiology of cysts of the semilunar cartilage. The author analyses 118 cases of his own, with special regard to the results of pneumo-arthrographic investigations carried through according to a special technique by Schaefer. In the course of this work, measurements of the meniscal base are for the first time used as radiological criteria indicating the presence of a cyst of the semilunar cartilage. Furthermore the well-known radiological signs of cysts, such as bone defects according to Albert and Keller, light central spot in the meniscal body, as well as Rauber's sign and horizontal rupture, are investigated as to the frequency of their incidence. For that purpose all the X-ray pictures were subjected to a further dose scrutiny. A list of all the 118 cases with their clinical and radiological data is found in the annex, together with the results of the operations and patho-anatomical investigations. (orig.)

    The dentigerous cyst is a developmental odontogenic cyst, accounting for 10% of all cysts of the jaws. The treatment options are decompression, marsupialization, or enucleation regarding the features of the lesions. In this article, a case of a 17-year-old adolescent girl having a large mandibular dentigerous cyst associated with an unerupted third molar is presented. The treatment is composed of decompression for 6 months and enucleation. Decompression and enucleation are a predictable choice in the treatment of large cysts. Radiologic evaluation is mandatory to decide for the appropriate time for the removal of the decompression stents, the enucleation time, and also for the evaluation of the adequate new bone formation for implant placement. The present case emphasizes the success of a conservative approach in the management of a large dentigerous cyst in a young patient and also the maintenance of the new bone formation without using any graft materials for the placement of dental implants.

    2004-03-01

    Intraspinal extradural synovial cysts are quite common in the lumbar spine. With respect to clinical presentation and surgical treatment, juxta-facet cysts (ganglion and synovial cysts) share identical characteristics and results. Nowadays, current treatment strategies of intraspinal juxta-facet cysts continue to inspire controversy regarding appropriate surgical approaches, and include many technical options. The purpose of this report is to illustrate the advantage of minimally invasive approaches in 3 cases of lumbar synovial cysts. We performed a small flavectomy in the 1st case, a transarticular partial facectomy, followed by etherologous bone graft fusion in the 2nd case, and a flavectomy and partial facectomy in the 3rd case. In our cases, a microsurgical approach to lumbar synovial cysts yielded to complete excision of the lesions and excellent pain relief, with early mobilization and hospital discharge of the patients. In our opinion, minimally invasive approaches and microsurgical excision of lumbar juxta-facet cysts are advantageous over conventional lumbar laminectomy because they reduce later development of segmental instability at the operative level, and therefore a less invasive strategy for intraspinal synovial cysts removal should be recommended.

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

    Background and Objectives The epidermoid cyst is a common benign disease of the skin caused by inflammation of hair cortex follicles and proliferation of epidermal cells within the dermis or superficial subcutaneous tissue. The purpose of this study was to investigate the characteristics of epidermoid cysts of the external auditory canal (EAC) by analyzing the clinical and radiologic features. Subjects and Methods The clinical records were retrospectively reviewed for patients diagnosed with epidermoid cyst of the EAC from March 2004 to December 2013. The epidermoid cysts were diagnosed clinically by endoscopy and microscopy examinations and by temporal bone CT images, and were confirmed by histopathologic examination. Characteristics of epidermoid cysts in bony EAC and cartilaginous EAC were compared. Results Eight patients had an epidermoid cyst in the bony EAC and nine patients had one in the cartilaginous EAC. Swelling and otalgia were common symptoms, but 47% of cysts were found incidentally. The mean age of patients was 49.6 years (age range, 26-67 years) in the bony EAC cases and 26.1 years (age range, 6-57 years) in the cartilaginous EAC cases. The mean size of the epidermoid cyst was 3.50 mm (size range, 2-7 mm) in the bony EAC cases and 9.55 mm (size range, 2-20 mm) in the cartilaginous EAC cases. Conclusions Comparison of epidermoid cysts of the bony EAC and the cartilaginous EAC revealed that epidermoid cysts of the bony EAC is usually found incidentally, arose in older patients and had smaller size.

  10. Bilateral postoperative maxillary cysts after orthognathic surgery: A case report

    International Nuclear Information System (INIS)

    Postoperative maxillary cysts are locally aggressive lesions, usually developing as delayed complications many years after radical antral surgery. This report describes a case of bilateral postoperative maxillary cysts following orthognathic surgery performed approximately 21 years previously. The patient complained of stinging pain on her right cheek. Radiographic examination revealed low-attenuation lesions on both maxillary sinuses with discontinuously corticated margins without distinct expansion or bone destruction. The cysts were enucleated with the removal of metal plates and screws for pain relief. Histopathological examination confirmed the diagnosis of postoperative maxillary cysts lined by ciliated, pseudostratified columnar cells. The patient has remained asymptomatic thus far, and there was no evidence of local recurrence at 21 months of postoperative follow-up.

    Full Text Available An 18-year-old male patient presented with a swelling in the neck with presumptive diagnosis of epidermal cyst (EC that was enucleated, histopathological examination confirmed the diagnosis. Four years later the patient presented with another swelling with similar clinical features. It was located on the midline of the neck at the hyoid bone. Excision of cyst was done and microscopically it showed features of thyroglossal duct cyst (TDC. Two months later a new swelling was noted on the right side of the neck. A complete surgical excision was done and the lesion was diagnosed as a lymphoepithelial cyst. The purpose of this report was to analyze each of the entities that were present in this case; since, the presence of three different cervical cystic lesions in the same patient is uncommon.

    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.

  14. Ovarian chocolate cysts

    International Nuclear Information System (INIS)

    Accurate preoperative staging of ovarian chocolate cysts is very important because recent hormonal therapy has been effective in low stage patients. However, it has been difficult to assess the preoperative stage of ovarian chocolate cysts. We evaluated the diagnostic potential of MRI in preoperative staging of 15 overian chocolate cysts. It was well known that the older the ovarian chocolate cyst was the more iron content it had. We examined the iron contents effect on T1 and T2 relaxation times in surgically confirmed chocolate cysts (stage II: 3 cases, stage III: 3 cases and stage IV: 9 cases by AFS classification, 1985) employing the 0.15-T MR system and 200 MHz spectrometer. There was a positive linear relation between T1 of the lesion using the MR system (T1) and T1 of the resected contents using the spectrometer (sp-T1); r = 0.93. The same relation was revealed between T2 and sp-T2; r = 0.87. It was indicated that T1 and T2 using the MR system was accurate. There was a negative linear relation between T1 and the iron contents ( r = -0.81) but no relation between T2 and the iron contents. T1 was 412 ± 91 msec for stage II, 356 ± 126 msec for stage III and 208 ± 30 msec for stage IV. T1 for stage IV was shorter than that for stage II and III, statistically significant differences were noted (p < 0.05). Thus, T1 was useful in differentiating a fresh from an old ovarian chocolate cyst. We concluded that T1 relaxation time using the MR system was useful for the staging of an ovarian chocolate cyst without surgery. (author)

    The aim of this study is to show the different diagnostic procedures and treatment in patients diagnosed with congenital choledochal cysts. Choledochal cysts are congenital anomalies of the bile ducts and include cystic dilatation of the extrahepatic and intrahepatic biliary ducts or both. The study shows ten patients diagnosed as having choledochal cysts. Diagnosis was established by clinical and radiographic findings including: ultrasound (US), magnetic resonance cholangiopancreatograpy (MRCP), endoscopic retrograde cholangiopancreatography (ERCP), percutaneous transhepatic cholangiography (PTC) and cytological examination of the bile juice. In the study choledochal cysts were classified according to the Todani classification. Most common cysts were type I (six cases); type III (one case), type IVa (one case) and two patients were type V cysts (Caroli disease). The most frequent symptoms were abdominal pain, jaundice and cholangitis. US findings were sensitive for the preliminary diagnosis of choledochal cysts in all the patients. MRCP accurately defined the cyst anatomy and the site of the biliary origin in all the cases with extrahepatic cysts. In three cases ERCP clearly demonstrated the cyst and by PTC smaller cysts were well defined. Cytological examination of the bile juice obtained during the PTC procedure showed malignant cells in one case. Therefore pancreaticoduodenectomy was performed and pathological examination showed associated cholangiocarcinoma. Five years after the operation the patient was well and free of the disease. Five patients underwent surgical treatment with a total cyst excision and Roux-en-Y hepaticojejunostomy while the surgical approach in two patients was partial cyst excision and cystojejunostomy. Patients with Caroli disease were conservatively treated and 3 with interventional endoscopic procedures. Despite US evidence suggesting choledochal cyst diagnosis, other supportive radiographic imaging modalities such as MRCP, ERCP and

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

    Tibial cyst formation following the use of bioabsorbable interference screws in anterior cruciate ligament (ACL) reconstruction is well-described; however, cyst formation after the use of metallic interference screws is not well-documented. We describe a case of osteolytic lesion of the proximal tibia presenting to us 20 years after ACL reconstruction using an autologous bone-tendon-bone graft. The original graft fixation technique was interference fixation with a metal screw in the tibial and femoral tunnels. A two-stage revision reconstruction of the ACL was undertaken with curettage and bone grafting of the tibial lesion in the first stage and reconstruction using a four-strand hamstring tendon in the second stage. The patient recovered satisfactorily with complete healing of the cyst and returned to pre-injury level of activities. We have reviewed case reports and case series that describe the aetiology of intra-osseous cyst formation following ACL reconstruction. PMID:26673117

    Full Text Available INTRODUCTION: Dermoid cysts or Dermoid sinus tracts are congenital inclusion cysts or sinuses lined by stratified squamous epithelium with normal dermal appendages. They occur due to sequestration of skin along the lines of embryonal clefts or fissures. They may arise f rom vestigial epithelial lined structures. There is a gradual accumulation of epithelial debris sebaceous and sweat secretions and hairs. Commonly dermoid cyst occurs in face, neck and scalp . [1] They can also occur in the soft palate, the tongue, the nasop harynx and the paranasal sinuses. Before the replacement of the nasofrontal fontanel by the nasal process of the frontal bone the dura and the skin are in contact without intervention of any bony structure. If any part of the ectoderm fails to separate fro m the dura and is carried to the prenasal space a dermoid cyst will be formed usually behind the nasal or frontal bone . [2 ,3 ] If it retains its connection with the skin, a sinus will result. Commonly the sinus will discharge cheesy offensive material or glo w abnormal hairs. Both cysts and sinuses may have a connection with an intracranial component through an abnormal foramen cecum in the anterior cranial fossa.

    Full Text Available 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.

    Purpose: To study the changes in subchondral bone marrow edema-like lesions and subchondral cysts from baseline to 12~30 months follow-up, and to evaluate the relationship with the progressive risk of cartilage loss in the same subregions. Methods: The status of bone marrow lesions and cartilage were scored in the same subregions according to the WORMS system. Within the follow-up survey, the changes of bone marrow lesions and cartilage in the same subregions were compared. By using a stable lesions group as the reference, a logistic regression model was used to assess the association of changes in bone marrow lesions status with cartilage loss. Results: Seven hundred and six cases of knees were included at baseline, and 135 cases participated in the 12~30 months follow-up evaluation.Bone marrow lesions were more common in the central subregions of tibia. The adjusted odds ratios of cartilage loss in the same subregion at follow-up for the different groups were 3.9 for newly developing bone marrow lesions and 0.1 for subregions with no lesions at baseline and follow-up. Conclusion: Bone marrow lesions are more common in load bearing subregions- Bone marrow edema-like lesions and subchondral cysts are associated with subregional cartilage loss.%目的:探讨膝骨关节炎软骨下骨髓水肿样及囊样病变与关节软骨缺失的关系.方法:683例膝关节骨关节炎患者纳入研究,其中126例135个膝关节进行了随访,随访期限为12~30个月.采用半定量积分系统WORMS分析膝关节骨髓水肿样和囊样病变的分布及邻近关节软骨状况.以骨髓病变稳定组作为参照,采用逻辑回归分析同一分区软骨下骨髓病损与软骨缺损之间的关系.结果:不伴有明显关节软骨病损的各分区其软骨下骨质病变发生率有明显差异,以胫骨中部分区较高.随访对照研究显示骨髓病变与软骨病损具有明显相关性,新发骨髓病灶相较稳定病灶的局部关节软骨

    BACKGROUND AND AIMS: Thyroglossal duct cysts (TDC) in children have a variable sonographic appearance. Some reports have suggested that TDCs appear on ultrasound as well defined, cystic masses with thin walls and posterior enhancement, whereas others have documented a heterogeneous echopattern within these lesions. In our experience, although TDCs in children have a variable ultrasound appearance, the most common appearance is that of a pseudosolid mass closely related to the hyoid bone. In this study we report on 23 patients with thyroglossal duct cysts and document the ultrasonic patterns. PATIENTS AND METHODS: All patients in whom the diagnosis of TDC was made clinically (by at least two head and neck surgeons) and in whom ultrasound detected a cystic mass related to the hyoid bone, were included in this study. Sonograms of 23 children with TDCs were reviewed. The features evaluated included their location, internal echogenicity, posterior enhancement, the presence of septa, a solid component and a fistulous tract. The echopattern was not correlated with the biopsy results. RESULTS: Three patterns of TDCs were identified: anechoic (13%); pseudosolid (56.5%); and a heterogeneous pattern (30.5%). The majority were midline (82.6%), showed posterior enhancement (56.5%), and had thin walls (82.6%). CONCLUSION: On ultrasound, TDCs in children are not simple cysts but have a complex pattern ranging from a typical anechoic cyst to a pseudosolid appearance (most common). Ahuja, A.T. (2000)

    The solid variant of aneurismal bone cysts (ABC) is considered rare. It occurs with greater frequency in pediatric patients and in the tibia, femur, pelvis and humerus. We present a case of a metaphyseal lytic lesion on the distal extremity of the radius in a child whose radiograph was requested after low-energy trauma. The hypothesis of a pathological bone fracture secondary to an aneurysmal bone cyst was suggested. After biopsy, the child underwent intralesional excision without bone grafting and the histopathological findings were compatible with the solid variant of aneurysmal bone cyst. PMID:27274493

    Full Text Available The paraurethral or Skene’s duct cyst, is a rare diagnostic entity in a newborn. It represents less than 0,5 % of congenital malformations of the urinary tract. All over the world it is reported an incidence of 1:2000 to 1:7000 in female births. In the newborn, the paraurethral cyst is caused by retention of secretions in the Skene's gland due to the obstruction of its ducts. Most of these cysts decrease in size during the first four to eight weeks, but they may cause symptoms of infection or urinary obstruction. They can also get formed from persistent embryonic remains of the mesonephric ducts (Wolffian duct, known as Gartner cysts and from the occlusion of unfused paramesonephric ducts (Müllerian. The case of a 25-day-old female, diagnosed with paraurethral cyst that underwent surgery and evolved successfully is presented.

    Full Text Available Hydatid cyst of the pancreas is rare. During the last 30 years, less than 40 cases have been reported in journals on Medline. This is a case report of a 35-year old woman with 2-year history of epigastric pain in whom an ultrasound and computed tomography showed the cyst of the body and tail of the pancreas 6x7 cm in diameters, which was supposed to be hydatid one. During surgery, an isolated hydatid cyst of the pancreas was found without communication with the pancreatic duct. The content of the cyst was removed, and pericyst was partially excised and drained. The recovery was uneventful and the patient has remained symptom free so far. Although rare, hydatid cyst should be considered in the differential diagnosis of the cystic lesions of the pancreas, particularly in patients coming from endemic areas and without history of pancreatitis.

    Cysts and bursae of the nasopharynx are uncommon and seldom symptomatic when compared with malignant tumors of this region. However, it is noteworthy that in the presence of symptoms, a good knowledge of their radiological appearance is useful to establish the correct diagnosis. Cysts of Rathke's pouch, pharyngeal bursa of Luschka, Tornwaldt's cysts, retentional cysts of the seromucinous glands, oncocytic cysts, intra-adenoid cysts, branchial cysts, prevertebral or retropharyngeal abscess and pseudocysts of the nasopharynx will be discussed in this paper.

    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

    2011-10-01

    Full Text Available Abstract Background Femoral head cysts have been identified as a risk factor for early femoral failures after metal-on-metal hip resurfacing arthroplasty (HRA based on limited scientific data. However, we routinely performed HRA if less than 1/3 of the femoral head appeared destroyed by cysts on the preoperative radiograph. This study was undertaken to analyze whether there was an added risk of early femoral failures in HRA when femoral head cysts were present. Methods This retrospective case-control study included 939 MOM HRAs operated by a single surgeon with use of the posterior minimally invasive surgical (MIS approach between November 2005 and January 2009. Patients with all diagnoses except osteonecrosis were included. Among them, 117 HRAs had femoral head cysts ≥ 1 cm identified in surgery. All cysts were treated with bone grafting using acetabular reamings packed into the cavitary defect (instead of filling the cysts with cement. The control group, which had no cyst observed at the time of surgery, was randomly selected from our database using computer algorithms to match those cases in the study group for the parameters of surgical date, age, gender, body mass index, diagnosis, femoral fixation method, and the size of the femoral component. Results The minimum follow-up was 24 months for both groups. The early femoral failure rate in the study group was 3/117 (2.6% and 0/117 in the control group; there was no statistical difference between these two groups (P = 0.08. In the study group, there were two femoral neck fractures (revised: both occurred in patients having a cyst size of 1 cm3; and there was one femoral component loosening at 3-year follow up in a patient having a cyst size of 2 cm3. Conclusion Although the risk of early femoral failures among the group with cysts appeared higher than the group without cysts, we could not demonstrate a significant statistical difference between the two groups. It is possible that bone

  9. Ganglionic cysts related to the scapula: MR findings

    International Nuclear Information System (INIS)

    To evaluate the magnetic resonance (MR) imaging characteristics of ganglionic cysts related to the scapula. We retrospectively reviewed 15 ganglionic cysts diagnosed by MR imaging in 14 patients who subsequently underwent surgical excision (n=8) or needle aspiration (n=1). Five other patients whose lesion-related symptoms were not too severe to manage underwent conservative treatment. We analyzed MR findings with regard to the size, shape and presence of internal septa, the location and signal intensity of the lesion, and associated findings such as change of rotator cuff muscle, labral tear and bone erosion. We also evaluated the presence of tear of rotator cuff tendon, tendinosis, and subacromial enthesophyte. The diameter of ganglionic cysts was 0.5-5.5 (mean, 2.8)cm, and they were round (n=2), ovoid (n=6), or elongated (n=7). Where internal septa were present (n=13), cysts were lobulated. Lesions were located in both scapular and spinoglenoid notches (n=9), only in the scapular notch (n=2), only in the spinoglenoid notch (n=2) or within the bone (n=2). In eleven cases they were very close to the superoposterior aspect of the glenoid labrum (n=11). On T1-weighted images, all lesions were seen to be iso- or hypointense to muscle, while on T2-weighted images, they were hyperintense, resembling joint fluid (n=14), except in one patient with hemorrhage. Associated findings were edema of the infraspinatus muscle (n=4), pressure erosion of the scapular neck (n=1), and labral tear (n=1). A torn supraspinatus tendon (n=2), supraspinatus tendinosis (n=3), and subacromial enthesophyte (n=2) were also present. MR imaging was helpful in diagnosing ganglionic cysts and detecting associated lesions

    2009-12-01

    Full Text Available Abstract Introduction A thyroglossal duct cyst is the most common congenital anomaly of the thyroid gland and midline masses in childhood (70% abnormality in childhood, 7% in adult. Carcinomas arising from a thyroglossal duct cyst are rare (only 1% of thyroglossal duct cyst cases and characterized by relatively non-aggressive behavior and rare lymphatic spread. They are also diagnosed mostly during the third and fourth decades of life. About 85% to 92% of all thyroglossal duct cyst carcinomas are papillary carcinomas. Case presentation We present the case of a 44-year-old Iranian woman with Cacausian ethnicity with a painless anterior neck mass that appeared gradually over three months. She had a history of frequent painful swelling of the anterior part of her neck, which subsided with antibiotic therapy. Thyroid functional tests were normal and a thyroid scinitigraphy showed a cold nodule in the left lobe of her thyroid. A computed tomography scan revealed a large, heterogeneous enhancing soft tissue mass with cystic components in the midline of the anterior neck space. This extended from the base of the tongue,(completely separated from its muscles, to the inferior aspect of the thyroid gland and showed the destruction of the hyoid bone and the thyroid cartilage. The diagnosis of a thyroglossal duct cyst with malignant transformation was maintained. A fine needle aspiration revealed papillary carcinoma. Conclusion This patient's case is presented because of its rare, aggressive, and invasive nature and rare and unusual manifestation, as well as its rapid increase in size, the destruction of the hyoid bone, chondrolysis of the thyroid cartilage, lymph adenopathy and the existence of a cold nodule in the thyroid gland.

  11. Periosteal ganglion: A cause of cortical bone erosion

    International Nuclear Information System (INIS)

    Three cases of periosteal ganglia of long bones are presented. These lesions are produced by mucoid degeneration and cyst formation of the periosteum to produce external cortical erosion and reactive periosteal new bone. They are not associated with a soft tissue ganglion or an intraosseous lesion. They may radiologically mimic other periosteal lesions or soft tissue neoplasms which erode bone. (orig.)

    Objective: Ovarian cysts are the most frequently encountered intra-abdominal masses in females in utero. They may, at times, require perinatal intervention. Using magnetic resonance imaging (MRI) as an adjunct to ultrasonography (US) in prenatal diagnosis, we sought to demonstrate the ability to visualize ovarian cysts on prenatal MRI. Materials and methods: This retrospective study included 17 fetal MRI scans from 16 female fetuses (23-37 gestational weeks) with an MRI diagnosis of ovarian cysts after suspicious US findings. A multiplanar MRI protocol was applied to image and to characterize the cysts. The US and MRI findings were compared, and the prenatal findings were compared with postnatal imaging findings or histopathology. Results: Simple ovarian cysts were found in 10/16 cases and complex cysts in 7/16 cases, including one case with both. In 11/16 (69%) cases, US and MRI diagnoses were in agreement, and, in 5/16 (31%) cases, MRI specified or expanded the US diagnosis. In 6/16 cases, postnatal US showed that the cysts spontaneously resolved or decreased in size, and in 1/16 cases, postnatal imaging confirmed a hemorrhagic cyst. In 4/16 cases, the prenatal diagnoses were confirmed by surgery/histopathology, and for the rest, postnatal correlation was not available. Conclusion: Our results illustrate the MRI visualization of ovarian cysts in utero. In most cases, MRI will confirm the US diagnosis. In certain cases, MRI may provide further diagnostic information, additional to US, which is the standard technique for diagnosis, monitoring, and treatment planning.

  14. Spinal perineurial and meningeal cysts.

    Science.gov (United States)

    Tarlov, I M

    1970-12-01

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

    To evaluate the incidence and characteristic findings of pineal cyst incidentally detected on magnetic resonance (MR) imaging. Brain MR images obtained in 2432 patients were retrospectively reviewed to determine the incidence and MR findings of pineal cysts, which were evaluated according to their size, shape, location, signal intensity, interval change, contrast enhancement and mass effect on adjacent structures. Cysts were encountered in 107(4.4 %) of 2432 patients evaluated. their size ranged from 1 X 1 X 1 to 15 X 8 X 9 (mean, 5.97 X 3.82 X 4.82)mm. All were spherical (n=53) or oval (n=54) in shape. Their margin was smooth and they were homogeneous in nature. On T1-weighted images, the cysts were seen to be hyperintense (n=57) or isointense (n=50) to cerebrospinal fluid, but less so than brain parenchyma. T2-weighted images showed them to be isointense (n=51)or hyperintense (n=56) to cerebrospinal fluid. The cysts were centrally located in 65 cases and eccentrically in 42. Compression of the superior colliculi of the tectum was demonstrated in 17 cases (15.9 %). NO patients presented clinical symptoms or signs related to either pineal or tectal lesions. Peripheral enhancement around the cyst after Gd-DTPA injection was demonstrated in 51 cases(100 %). Follow-up examinations in 19 cases demonstrated no interval change. The incidence of pineal cysts was 4.4 %. The MR characteristics of simple pineal cysts include: (1) an oval or spherical shape, (2) a smooth outer margin and homogeneous nature, (3) isosignal or slightly high signal intensity to cerebrospinal fluid on whole pulse sequences, (4) ring enhancement after contrast injection, (5) an absence of interval change, as seen during follow up MR study. These MR appearances of pineal cysts might be helpful for differentiating them from pineal tumors.

  20. Contrast-enhanced MRI of subchondral cysts in patients with or at risk for knee osteoarthritis: The MOST study

    International Nuclear Information System (INIS)

    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 Study (MOST) 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.

    Hydatid disease most commonly affects the liver and lungs but no organ is immune. Splenic hydatid cyst is a rare clinical entity. Although the patients are usually asymptomatic, the disease may present with secondary infection, adhesion to adjacent organs with fistulisation or rupture into abdominal cavity. We present a 67 year old women with splenic hydatid cyst. Severe adhesions and tumorlike growth were found in the retroperitoneal region. To our knowledge, retroperitoneal invasion with a splenic hydatid cyst is a very rare clinical condition. Total splenectomy was performed without complication. PMID:21391192

    Full Text Available On HRCT scans, lung cysts are characterized by rounded areas of low attenuation in the lung parenchyma and a well-defined interface with the normal adjacent lung. The most common cystic lung diseases are lymphangioleiomyomatosis, Langerhans cell histiocytosis, and lymphocytic interstitial pneumonia. In a retrospective analysis of the HRCT findings in 50 patients diagnosed with chronic paracoccidioidomycosis, we found lung cysts in 5 cases (10%, indicating that patients with paracoccidioidomycosis can present with lung cysts on HRCT scans. Therefore, paracoccidioidomycosis should be included in the differential diagnosis of cystic lung diseases.

    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. PMID:21226768

    The calcifying odontogenic cyst (COC) is a rare disorder of the jaws and shows various radiographic features. The purpose of this study is to describe the different radiographic appearances of 2 cases of COC. Case 1 was located in the posterior maxilla extending into maxillary sinus, showing unilocular radiolucency with a well-defined margin. Cortical bone expansion and thinning were prominent. Root resorption of adjacent teeth was apparent. Case 2 showed unilocular radiolucency with a calcified material. Calcification was supposed to be dystrophic dental hard structures, detected at the periphery of the lesion. Ghost cell and proliferation of ameloblastoma-like tissues were common features for these two lesions on histopathological findings. This reports presented common and atypical radiographic features of the COC.

    Full Text Available Thoracic duct cysts are very rarely observed cysts of the mediastinum. These cysts, which can become established in the costovertebral sulcus or the visceral compartment, have generally been reported at the level of the 10th and 11th vertebrae; however, they can be observed at any location along the ductus [1]. A 37-year-old male patient complained of chest pain for the last 3 months that especially increased after meals. He complained of shortness of breath while walking or going up the stairs, for the last month. The lung graphy showed an increased darkening at a 5x6cm smooth (clean-cut, regular, orderly bordered shadow just behind the heart shadow. The patient%u2019s computed thorax tomography showed a retrocardiac-paravertebral, middle line positioned, 8.5x7x6 cm proportioned, regular bordered, thin walled, homogenous cystic bulk at the subcarinal level. The patient, who could not be relieved with medical treatment, was taken to surgery. The lesion was reached by right posterolateral thoracotomy, and drainage of lymph-containing cystic fluid and excision of the cyst walls were performed by incising the thoracic duct cyst with a mediastinal pleura incision. Mass ligation was then performed to the thoracic duct. We wanted to present our thoracic duct cyst case in this article due to the currently limited number of actual cases reported in the literature.

    The Mullerian duct cyst is a remnant of the caudal ends of the fused embryologic paramesonephric ducts (or Mullerian ducts). Preoperative distinction of ovarian cyst from a Mullerian duct cyst is important and is based on visualization of the ipsilateral ovary separate from the mass. Mullerian duct cysts may also be mistaken as paratubal, paraovarian or peritoneal inclusion cysts and hydrosalpinx. Thus, preoperative diagnosis of Mullerian cyst of the uterus can be very challenging. However, w...

    One of the rarest situations regarding an adrenal incidentaloma is an adrenal cyst. We present the case of a 61-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.

  10. Prenatal and postnatal sonographic findings of uncomplicated ovarian cysts: 'Daughter cyst' sign

    International Nuclear Information System (INIS)

    To compare pre- and postnatal sonographic findings of ovarian cysts in neonates and to present a 'daughter cyst' sign for uncomplicated ovarian cysts. The study group consisted of six cases of neonatal ovarian cysts which were evaluated by both prenata (mean, IUP 36 weeks+3 days) and postnatal(mean, 2 days after birth) ultrasound studies. Two ovarian cysts were confirmed by surgery and the remaining four were clinically diagnosed. Postnatal sonography was prospectively evaluated and prenatal ultrasound scans were retrospectively evaluated. The size, contents, and wall thickness of the cyst were evaluated. We also analyzed presence or absence of a 'daughter cyst' , defined as a small cyst surrounded by a complete wall, protruding into the cyst lumen or along the cyst wall. Pathologic correlation of the daughter cyst was performed in two cases. The mean sizes of the ovarian cysts were 59.6 X 46.1 mm on prenatal and 73.0 X 49.2 mm on postnatal studies. Five were anechoic and thin walled cysts on both pre- and postnatal studies. One case revealed debris in the cyst lumen on prenatal study but was completely involuted on postnatal study. All six were unilocular in shape. The 'daughter cyst' sign was seen in two on prenatal and in four (80%) on postnatal studies. The 'daughter cyst' on sonography was corresponded to a follicle on pathology. The 'daughter cyst' sign appeared to be helpful for the diagnosis of neonatal ovarian cyst on both pre- and postnatal ultrasound studies.

    Full Text Available SUMMARY: Eruption cyst is a dentigerous cyst of the soft tissue of the jaws that forms around the crown of an erupting primary or permanent tooth, due to separation of the dental follicle from the crown. Eruption cysts usually present as solitary swellings on the alveolar ridge mucosa, whereas multiple eruption cysts presenting simultaneously or in short intervals are uncommon.The case of a 2 month old Caucasian boy with two adjacent eruption cysts, manifesting as a congenital bilobular tumor of smooth surface and blue color, on the mandibular central incisors area is presented. The lesion was diagnosed as a “hemangioma”, but it progressively grew in size and changed in color. The patient’s and family medical history were non contributory.Radiographic examination revealed the superficial location of the primary mandibular central incisors within the soft tissues, and showed no abnormal bone resorption. With the diagnosis of double eruption cyst,a monthly follow-up of the patient was suggested and a month after the clinical examination the cyst disappeared spontaneously without noticeable hemorrhage.A year later the primary mandibular central incisors had erupted normally and there was no residual lesion.

    2009-03-01

    Full Text Available Echinococcus granulosus is considered the major cause of humanhydatid cysts. Usually the duration of cyst formation is 10-20 years. This period shortens significantly upon rupture of aprimary cyst. The literature describes low incidence of primaryinvolvement of ovary as a site of hydatid cyst formation. Ourcase is the first report on ovarian hydatid cyst in Iran. A 60-year-old woman was presented with abdominal pain in the leftlower quadrant area. Paraclinical data were suggestive of neoplasiaand preoperative diagnosis was ovarian tumor. Duringlaparotomy, multiple cysts resembling hydatid cysts were observedin the left ovary. Pathological examination confirmed thediagnosis of hydatid cyst. Although there is a small possibilityof secondary ovarian echinococcal disease, it is more probablefor this case to be primary infection, as the patient had developedovarian hydatid cysts 15 years after hepatic involvementand recurrence after 30 months is very uncommon.

    1984-06-01

    Anamnesis and treatment of two cases of arachnoid cysts extending into the subarachnoid space are described. No traumatic incident was discovered in the previous history of these two patients. The causal genesis of neurological signs of deficiency in patients with arachnoid and acquired cysts is discussed. However, the cause of the development of a subdural hygroma in arachnoid cysts remains unclarified. CT findings of arachnoid cysts with a hypodense zone between brain surface and the vault of the cranium always require an investigation into the possibility of a spontaneous emptying of the cyst or of a congenital and not only localised extension of the cyst itself.

    We report a case of giant Muellerian duct cyst in a 6 month-old-boy with urinary tract infection. A mass displacing the bladder and prostatic urethra anteriorly was found on the voiding cystourethrogram, and it was a oval shaped retrovesical anechoic cyst on the abdominal ultrasonogram. On MRI, it was a tear-drop shaped cyst of isosignal intensity with a projection toward the prostatic urethra and located in the midline of vesicorectal space. Grossly, the cyst had communication with prostatic urethra and both vas deferenses were drained to the cyst. Pathologically it was confirmed as a Muellerrian duct cyst lined with squamous spithelium.

    We report the CT and MRI findings in a 5-year-old girl with histologically proven frontosphenoidal dumbbell-shaped dermoid cyst with sinus tracts in the frontal bone extending to the dura. Although the most common location for dermoid cyst in the head and neck is at the frontosphenoidal region, presentation with a tract extending deep to underlying bone or the intracranium is rare for this location. Complete surgical excision has been widely accepted as the basic treatment for dermoid cyst. However, the relatively extensive nature of such surgical interventions may be associated with serious risks to both visual acuity and cosmesis. From a clinical viewpoint, even if these are rare cases, radiological imaging is crucial for orienting the deeper extension of the lesion for presurgical planning. (orig.)

    Ovarian cysts are fluid filled sacs inside the ovary that are common among women during their reproductive years. Most cysts are harmless and go away without any treatment, but some may cause problems such as rupturing, bleeding, or pain; and surgery may be required to remove the cyst(s). When the follicles (sacs) in the ovaries do not rupture, they form small cysts called 'simple cysts'. These form whenever ovary produces too much of estrogen hormone. 'Dermoid cysts' & 'chocolate cysts' are ...

  1. Intraosseous epidermoid cysts in the distal phalanx of two dogs

    International Nuclear Information System (INIS)

    Two dogs were presented with a history of lameness associated with swelling of one of the digits. Radiographs of the affected digits revealed an irregularly mineralized, smoothly marginated proliferative bone lesion in the distal phalanx of one dog and a destructive bony lesion in the distal phalanx of the second dog. The differential diagnosis included nail bed carcinoma, malignant melanoma, osteomyelitis, and subungual keratoacanthoma. Radiographic findings and no response to medical treatment resulted in amputation and submission of the digits for a histopathologic diagnosis. Histologic examination of the distal phalanx of the digits revealed benign epidermoid cysts associated with either bony proliferation or osteolysis. Excision of the lesions was curative. This report presents the clinical, radiographic, and histopathologic findings associated with intraosseous epidermoid cysts in the distal phalanx of two dogs

    Eosinophilic granuloma is a common expression of Langerhans cell histiocytosis and corresponds with typical bone lesions. The radiographic appearance of eosinophilic granuloma in the jaw is variable and not specific. It may resemble periodontitis, radicular cyst, or malignancies. The purpose of this report is to describe the characteristic radiographic features of eosinophilic granuloma of a 39-year-old male. The lesion in the anterior mandible was first diagnosed as radicular cyst because the radiographic findings were ovoid radiolucent lesion with well-defined border. However, careful interpretation revealed a non-corticated border and floating tooth appearance that were the characteristic radiographic features for the differential diagnosis. Early clinical signs of eosinophilic granuloma can occur in the jaw and a bony destructive lesion might be mistaken for periodontitis or an odontogenic cystic lesion; therefore, careful interpretation of radiographs should be emphasized.

    The glandular odontogenic cyst is a rare lesion described in 1987. It generally occurs at anterior region of mandible in adults over the age of 40 and has a slight tendency to recur. Histopathologically, a cystic cavity lined by a nonkeratinized, stratified squamous, or cuboidal epithelium varying in thickness is found including a superficial layer with glandular or pseudoglandular structures. A 21-year-old male visited Dankook University Dental Hospital with a chief complaint of swelling of the left posterior mandible. Radiographically, a huge multilocular radiolucent lesion involving impacted 3rd molar at the posterior mandible was observed. Buccolingual cortical expansion with partial perforation of buccal cortical bone was also shown. Histopathologically, this lesion was lined by stratified squamous epithelium with glandular structures in areas of plaque-like thickening. The final diagnosis was made as a glandular odontogenic cyst.

    International Nuclear Information System (INIS)

    We studied computed tomographic findings in the axial sections of postoperative maxillary cyst diagnosed histopathologically. The results were as follows: 1. Nineteen patients (11 males and 8 females) were studied. The average age was 44.9 years and the average period after the initial surgery of maxillary sinus was 24.3 years. 2. The lesion occupied the maxillary sinus horizontally in 13 cases and the inferior border of the lesion extended to the alveolar area in 17 cases. The forms of the lesions fell into three types; absorbed bone type, simular sinus type and unsettled type. The lesion was unilocular in 15 cases. 3. The lesion protruded into the soft tissue in 15 cases. 4. The CT numbers of the lesions ranged from 28.5 to 73.0 H.U., and the average was 44.6 H.U. 5. In the bilateral surgery cases, the findings of the opposite side fell into three types; filled bone type, reduced cavity type and soft tissue density area type. (author)

  6. Dermoid cyst of the ovary

    International Nuclear Information System (INIS)

    Unsuspectable chronic rupture was discovered during surgical remotion of a very large ovarian dermoid cyst. Abdomen X-ray, US and CT examinations were presurgically performed. Standing X-ray projection of the abdomen allowed the appearing of a new radiographic finding of dermoid cyst, the ''fat floating'' as the equivalent of the ''gravity dependent layering'' in US and CT features. Thisding of dermoid cyst, the ''fat floating'' as the equivalent of the ''gravity dependent layering'' in US and CT features. This radiographic sign appears as an horizontal line between two soft tissues of different opacity; it is caused by oleous and sebaceous fluid floating over serous fluid and over serous fluid and over intracystic debris. Literature was reviewed and radiographic findings in dermoid cyst were reconsidered; the sign of ''fat floating'' could enhance the diagnostic accuracy of abdomen X-ray. So when a pelvic or an abdominal-pelvic mass is discovered in a young woman, standing projection is required for abdomen X-ray. Rupture of a dermoid cyst may happen without notice and chronically; CT has been more accurate than US in evaluating rupture, in particular the peritoneal spread of oleous pseudocyst

  7. Choroid plexus cysts. MR and CT findings

    International Nuclear Information System (INIS)

    The MRI and CT characteristics of choroid plexus cysts in the lateral ventricles were investigated. Of eight patients with choroid plexus cysts, six had bilateral and multiple cysts that were small in size, and two patients had unilateral solitary cysts. Choroid plexus cysts were well visualized on T2-WI and proton density-WI with higher signal intensity than the CSF in the lateral ventricles. The walls of cysts were well enhanced with Gd-DTPA. MRI has a distinct advantage over conventional CT for visualization of choroid plexus cysts that are small in size, which may be multiple and bilateral. With the widespread use of MRI, asymptomatic choroid plexus cysts may become common incidental findings. (author)

    Perineural cysts have become a common incidental finding during lumbosacral magnetic resonance (MR) imaging. Only some of the symptomatic cysts warrant treatment. The authors describe the successful operative treatment of a patient with, to the best of their knowledge, the largest perineural cyst reported to date. A 29-year-old woman had been suffering from long-standing constipation and low-back pain. During an obstetric investigation for infertility, the clinician discovered a huge presacral cystic mass. Computed tomography myelography showed the lesion to be a huge Tarlov cyst arising from the left S-3 nerve root and compressing the ipsilateral S-2 nerve. The cyst was successfully treated by ligation of the cyst neck together with sectioning of the S-3 nerve root. Postoperative improvement in her symptoms and MR imaging findings were noted. Identification of the nerve root involved by the cyst wall, operative indication, operative procedure, and treatment of multiple cysts are important preoperative considerations. PMID:17688070

    We review 12 cases of ganglion cyst with carpal tunnel syndrome in 11 patients seen at the Hand Rehabilitation Center. Mean age was 42 years (range, 28 to 60 years). One half of the cysts were associated with direct trauma, usually with wrist hyperextension. Symptoms usually developed after the appearance or sudden growth of the cyst. Motor conduction or distal sensory latency was abnormal in seven of eight studied cases. Tinel's sign on tapping the cyst may be pathognomonic for this syndrome. Cyst removal and incision of the flexor retinaculum relieved the symptoms in 11 cases. The other case had total resolution after spontaneous cyst rupture. This syndrome is successfully treated with cyst decompression with release of the carpal canal and has an excellent prognosis. To our knowledge this represents the largest operative series of carpal tunnel syndrome and ganglion cyst. PMID:3241055

Surgical drainage is the preferred therapy for choledochal cyst, but cystic duplication necessitates surgical excision as duplications may contain heterotopic gastric mucosa leading to peptic ulceration of the biliary tract. We report a case of biliary tract duplication cyst containing heterotopic alimentary mucosa which had initially been diagnosed and surgically treated as a choledochal cyst.

  2. Concomitant bilateral testicular epidermoid cysts

    International Nuclear Information System (INIS)

    Epidermoid cyst of the testis is a rare benign germ tumor, comprising 1-2% of all resected benign testicular masses. Approximately 300 cases have been reported to date. Unilateral involvement has often been reported in the English literature. However, bilateral occurrence is very rare and to the best of our knowledge, there only 3 previous reports of bilateral testicular epidermoid cysts. The fact that they are completely benign makes them amenable to treatment by local excision, thereby saving patient from orchidectomy. Recognition of their characteristic ulatrsonographic features is very important to avoid unnecessary intervention. We present here, a case of bilateral epidermoid cyst in which characteristic ultrasound (US) findings allowed testis-sparing enucleation instead of radical orchiectomy. (author)

    Epidermoid cysts are benign, uncommon lesions (1% of all intracranial tumors). Their localization is intradiploic in 25% of cases, and exceptionally subtentorial. We report here a rare case of giant intradiploic infratentorial epidermoid cyst. A 74-year old patient presented with recent diplopia and sindrome cerebellar. CT scan and MR imaging revealed a giant osteolytic extradural lesion of the posterior fossa (5.2 cm x 3.8 cm) with a small area of peripheral enhancement after contrast injection. Retrosigmoid suboccipital craniectomy allowed a satisfactory removal of the tumor, followed by an acrylic cranioplasty. The outcome was good. Neuropathological examination confirmed an epidermoid cyst. We review the literature and discuss our case. PMID:18008017

    Cystic hydatid disease is a zoonosis caused by infection with the larval cysts of Echinococcus granulosus. Cysts commonly develop in the liver and lungs. Diagnosis in non-endemic regions is often delayed due to a failure to consider hydatidosis. This results from a non-specific presentation and a failure to record an accurate geographical history. The diagnosis requires integrating an appropriate index of suspicion with correct interpretation of imaging and serological tests. In our case, a 44-year-old woman of Yemeni origin presented to a UK hospital with chest pain, pruritus and weight loss. Following detection of pulmonary nodules, a CT-guided biopsy was carried out to exclude malignancy. Iatrogenic cyst rupture precipitated an acute eosinophilic pleurisy. Cystic hydatid disease was subsequently diagnosed following strongly positive hydatid serological tests. This case illustrates the importance of considering diagnoses appropriate to an individual's geographical history particularly in the context of rising immigration and foreign travel. PMID:22778194

  16. Juxta-facet cysts: MR imaging

    International Nuclear Information System (INIS)

    The term juxta-facet cyst summarizes synovial cysts, arising from degenerated facet joints and ganglion cysts, developing from mucinous degeneration of periarticular connective tissue. Most juxta-facet cysts are observed at the L4/5 level, which generally has the most motion within the lumbar spine. In this retrospective study 31 juxta-facet cysts in 28 patients were detected within 2898 lumbar MRI studies over a 2-year period (frequency 1%). 24 patients complained of back and lower extremity pain, the other 4 patients had unilateral back pain. In 7 cases radicular symptoms were observed, in 6 patients a neurogenic claudication. In 78% of the patients juxta-facet cysts were responsible for clinical symptoms. MRI is the diagnostic imaging technique of choice due to a high sensitivity. The juxta-facet cysts were located extradural, laterally to the thecal sack and adjacent to a degenerated facet joint. In all but one cases the cysts showed a signal intensity equivalent to cerebrospinal fluid. T2-weighted pulse sequences in sagittal orientation were very useful in delineating the hypointense cyst wall. In 1 patient with acute radicular pain MRI demonstrated a subacute hemorrhage within a juxta-facet cyst. Calcifications and gas-filled cysts can be missed with MRI, but will be demonstrated by computed tomography. 45% of the juxta-facet cysts showed an enhancement of the cyst wall after injection of Gd-DTPA. Spontaneous reduction or resolution of the cyst may occur during rest. Injection of corticosteroids into the corresponding facet joint may reduce the inflammatory process and resolve the symptoms in up to 70%. Surgical resection of the cyst is indicated in case of intractable pain and significant neurologic deficit and generally produces good relief from radicular symptoms. (orig.)

    Full Text Available Epidermoid cysts are common cystic lesions in the skin, ovaries, and testicles, but their occurrence in the oral cavity is uncommon. They consist of cysts delimited by a fibrous capsule without cutaneous annexes and are lined by stratified squamous epithelium. The differential diagnosis includes ranula, dermoid cysts, and lingual thyroid. Despite their benign presentation, these cysts can cause functional limitations, requiring special clinical attention for extensive lesions located in regions that preserve vital structures. This paper aims to report a case of epidermoid cyst in patient with swallowing and breathing difficulty, highlighting the clinical and surgical planning.

    Tarlov or perineural cysts are nerve root cysts found most commonly at the sacral spine level arising between covering layers of the perineurium and the endoneurium near the dorsal root ganglion and are usually asymptomatic. Symptomatic sacral perineural cysts are uncommon but sometimes require surgical treatment. A 69-year-old male presented with pain in the buttock. He was diagnosed as having a sacral cyst with magnetic resonance imaging. For the nonoperative diagnosis and treatment, caudal peridurography and block were performed. After the treatment, the patient's symptom was relieved. We suggest a caudal peridural block is effective in relieving pain from a sacral cyst. PMID:22787551

  2. Arachnoid cyst of the middle cranial fossa

    International Nuclear Information System (INIS)

    The middle cranial fossa is the most common site for intracranial arachnoid cysts. Galassi and his associates have provided a useful classification of middle fossa arachnoid cysts based on their computed tomographic appearances. The Type I cyst is a small lenticular lesion. The Type II cyst is quadrangular in shape, reflecting a completely open insula. The Type III cyst appears as a large area of smoothly rounded lucency, with a significant compression of the brain. We report a 2-year-old boy with a middle fossa arachnoid cyst. This cyst differed from the type of Galassi's classification in its extension. Computerized tomograms showed low-density lesions of the bilateral middle cranial fossa and suprasellar area, which was not enhanced with contrast medium. Magnetic Resonance Imaging (MRI) showed a CSF-like pattern (Kjos) and revealed delicate anatomical structures in the surrounding brain. Arachnoid cysts are usually single lesions. However, not infrequently these cystic cavities may be divided by membranous septa into two or more compartments. Bilateral, more or less symmetrical arachnoid cysts in the middle cranial fossa as seen in this patient, however, seem to be very rare. Only a few such cases have been reported previously. MRI was superior to X-ray CT in characterizing intracranial cystic lesions because of its ability to categorize cysts into Kjos's three groups on the basis of the intensity pattern of the cyst contents, thereby improving diagnostic specificity and patient management.

    Tarlov or perineural cysts are nerve root cysts found most commonly at the sacral spine level arising between covering layers of the perineurium and the endoneurium near the dorsal root ganglion. The cysts are relatively rare and most of them are asymptomatic. Some Tarlov cysts can exert pressure on nerve elements resulting in pain, radiculopathy and even multiple radiculopathy of cauda equina. There is no consensus on the appropriate therapeutic options of Tarlov cysts. The authors present a case of two sacral cysts diagnosed with magnetic resonance imaging. The initial symptoms were low back pain and sciatica and progressed to cauda equina syndrome. Surgical treatment was performed by sacral laminectomy and wide cyst fenestration. The neurological deficits were recovered and had not recurred after a follow-up period of nine months. The literature was reviewed and discussed. This is the first reported case in Thailand.

    Ganglion cysts were diagnosed in a 4-month-old male Afghan Hound. Grossly, the subcutaneous ovoid cysts around the caudal right elbow joint and left ischiatic tuberosity had abundant mucinous fluid and internal folding. The lesions recurred twice around the elbow joint after surgical removal. Neither cyst communicated with the joint cavity. Histologically, the cyst wall consisted of inner myxomatous and outer immature connective tissue. Some parts of the cyst wall had various stages of myxoid metaplasia of collagen tissue leading to new cyst formation. Ultrastructural study revealed that cells in the myxoid metaplastic lesion had well-developed cytoplasmic secretory elements, including abundant rough endoplasmic reticulum, Golgi apparatus, and many smooth-walled vesicles. These ganglion cysts apparently resulted from the metaplasia of fibroblasts to secreting cells. PMID:10896396

  5. New insights about suprapatellar cyst

    Directory of Open Access Journals (Sweden)

    Tomislav Crnkovic

    2012-02-01

    Full Text Available bursa is located between the quadriceps tendon and femur, and it develops before the birth as a separate synovial compartment proximal to the knee joint. By the fifth month of fetal life there is a suprapatellar septum between the knee joint cavity and suprapatellar bursa which later perforates and involutes in a way that a normal communication between the cavity of bursa and knee is established. A small portion of the embrionic septum can later lag as more or less expressed suprapatellar plica. In case when suprapatellar plica has a small communication with valve mechanism or in case of complete septum, bursa becomes a separate compartment and potential location for the suprapatellar cyst development. Magnetic resonance imaging is recognised as the gold standard in diagnosis of knee cysts because of its ability to show cystic nature of the lesion, its relationship with other anatomic structures, as well as to establish whether other knee pathologies are present. Considering treatment possibilities, majority of cysts around the knee resolve spontaneously and should be treated by aspiration and application of corticosteroids. Suprapatellar cyst is a very rare knee pathology and it can in some occasions be treated using open or arthroscopic surgery.

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

    Hydatid cyst disease, which is endemically observed and an important health problem in our country, involves the spleen at a frequency ranking third following the liver and the lungs. In this study, we aimed to evaluate the efficacy and results of management in splenic hydatid cysts. The demographic data, localization, diagnosis, treatment methods, and the length of postoperative hospital stay of patients with splenic hydatid cysts in a 12-year period were evaluated retrospectively. Seventeen cases were evaluated. Among these, 13 were females and four were males. Seven had solitary splenic involvement, eight had involvement of both the spleen and the liver, and two had multiple organ involvement. Ten had undergone splenectomy, one had undergone distal splenectomy, and the remaining cases had undergone different surgical procedures. The patients had received albendazole treatment in the pre- and postoperative period. One patient had died secondary to hypernatremia on the first postoperative day. The clinical picture in splenic hydatid cysts, which is seen rarely, is usually asymptomatic. The diagnosis is established by ultrasonography and abdominal CT. Although splenectomy is the standard mode of treatment, spleen-preserving methods may be used. PMID:26730005

    To compare pre- and postnatal sonographic findings of ovarian cysts in neonates and to present a 'daughter cyst' sign for uncomplicated ovarian cysts. The study group consisted of six cases of neonatal ovarian cysts which were evaluated by both prenata (mean, IUP 36 weeks+3 days) and postnatal(mean, 2 days after birth) ultrasound studies. Two ovarian cysts were confirmed by surgery and the remaining four were clinically diagnosed. Postnatal sonography was prospectively evaluated and prenatal ultrasound scans were retrospectively evaluated. The size, contents, and wall thickness of the cyst were evaluated. We also analyzed presence or absence of a 'daughter cyst' , defined as a small cyst surrounded by a complete wall, protruding into the cyst lumen or along the cyst wall. Pathologic correlation of the daughter cyst was performed in two cases. The mean sizes of the ovarian cysts were 59.6 X 46.1 mm on prenatal and 73.0 X 49.2 mm on postnatal studies. Five were anechoic and thin walled cysts on both pre- and postnatal studies. One case revealed debris in the cyst lumen on prenatal study but was completely involuted on postnatal study. All six were unilocular in shape. The 'daughter cyst' sign was seen in two on prenatal and in four (80%) on postnatal studies. The 'daughter cyst' on sonography was corresponded to a follicle on pathology. The 'daughter cyst' sign appeared to be helpful for the diagnosis of neonatal ovarian cyst on both pre- and postnatal ultrasound studies.

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

  10. Primary bone tumours of the hand

    International Nuclear Information System (INIS)

    Twenty-one primary bone tumours of the hand in children from 8 paediatric hospitals are reported. Osteochondromas and enchondromas were not included. Our material consisted of 16 patients with common tumours (3 Ewing's sarcoma, 5 aneurysmal bone cyst, 6 osteoid osteoma and 2 epithelioma) and 5 patients with uncommon tumours (osteoma, simple bone cyst, haemangiopericytoma, capillary angiomatous tumour and benign ossifying fibroma or osteoblastoma). The X-ray diagnosis of the common tumours should have high concordance with histology, whereas that of uncommon tumours in much more difficult and uncertain. The characteristic features of Ewing's sarcoma are stressed as all our children with this tumour had a delayed diagnosis and a fatal outcome. Differential diagnosis with other short tubular bone lesions of the hand - specifically osteomyelitis - is discussed and the posibilities of microscopic diagnosis are stressed. (orig.)

    International Nuclear Information System (INIS)

    To investigate the incidence of the asymptomatic thyroglossal duct anomalies and to review the literature and make comments on the significance of this condition. A total of 80 cadavers were dissected in the present study. This study was carried out during 2005, where the cadavers were randomly included from the criminal laboratories of the Ministry of Justice, Republic of Turkey in Istanbul. None of the cadavers had laryngeal and cervical injuries resulting from a trauma or the cause of their death. The examined cadavers included 59 men and 21 females, and their ages were ranged from 35-80 years old. The larynges were removed and fixed in 10% formalin and then dissected. The sections were examined using surgical SMZ 10 Nikon stereomicroscope. We evaluated the presence, localization and diameter of the cysts with regard to age and sex of the cadavers. We observed a total of 12 different localization of thyroglossal ducts and cysts among the 80 dissected cadavers. Ten of these ducts cysts were found in males with an age range of 35-68 years and 2 female cadavers aged 45-65 years. In 6 cases, the thyroglossal ducts and cysts were located in the left of the midline of the neck, while 3 cases were from the right of the midline, and the remaining was located on the midline of the neck. In all cases, thryoglossal ducts and cysts were complete and restricted to the infrahyoid region: all of them had connection with the hyoid bone, but not with the perichondrium of the cartilage. In addition, the thyroglossal ducts have connection with the left lobe of the thyroid glands in 3 cases, one case in the right lobe, and 2 cases with the isthmus of the thyroid gland. Finally in 5 cases thyroglossal ducts were complete and had well developed cysts. Thyroglossal duct remnants are one of the most often seen congenital asymptomatic masses of the neck region (7%). The presence of these duct remnants may lead to abnormal phonation and epithelial carcinomas. Therefore, correlation of

  13. Congenital cervical bronchogenic cyst: A case report

    Directory of Open Access Journals (Sweden)

    Kiralj Aleksandar

    2015-01-01

    Full Text Available Introduction. Bronchogenic cysts are rare congenital anomalies of the embryonic foregut. They are caused by abnormal budding of diverticulum of the embryonic foregut between the 26th and 40th day of gestation. Bronchogenic cysts can appear in the mediastinum and pulmonary parenchyma, or at ectopic sites (neck, subcutaneous tissue or abdomen. So far, 70 cases of cervical localization of bronchogenic cysts have been reported. Majority of bronchogenic cysts have been diagnosed in the pediatric population. Bronchogenic cysts of the cervical area are generally asymptomatic and symptoms may occur if cysts become large or in case of infection of the cyst. The diagnosis is made based on clinical findings, radiological examination, but histopathologic findings are essential for establishing the final diagnosis. Treatment of cervical bronchogenic cyst involves surgical excision. Case Outline. Authors present a case of a 6-year-old female patient sent by a pediatrician to a maxillofacial surgeon due to asymptomatic lump on the left side of the neck. The patient had frequent respiratory infections and respiratory obstructions. Magnetic resonance imaging (MRI of the neck was performed and a well-circumscribed cystic formation on the left side of the neck was observed, with paratracheal location. The complete excision of the cyst was made transcervically. Histopathological findings pointed to bronchogenic cyst. Conclusion. Cervical bronchogenic cysts are rare congenital malformations. Considering the location, clinical findings and the radiological features, these cysts resemble other cervical lesions. Surgical treatment is important because it is both therapeutic and diagnostic. Reliable diagnosis of bronchogenic cysts is based on histopathological examination.

  14. Complex renal cysts associated with crizotinib treatment

    International Nuclear Information System (INIS)

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

    Hydatid cysts are usually located in the liver and lungs. Skeletal echinococcosis is relatively rare and that of the rib is exceptional. Less than 50 cases of costal echinococcosis have been reported in the literature so far. To our knowledge, only one case report of thoracic outlet syndrome due to echinococcal cyst in the first rib was described in 1995. Accurate pre-operative diagnosis is important but may be challenging in some cases. Reported here is a case of echinococcosis of the first rib in a young adult who was presented with thoracic outlet syndrome. Plain chest radiograph, CT scan and MRI were performed. The imaging features were suggestive of a solitary aneurysmal bone cyst and the differential diagnosis included echinococcosis of the first rib. The lesion was completely resected and the histopathological examination confirmed the diagnosis of echinococcosis. PMID:22131660

    The synovial and ganglion cysts originating from the facet joint have been named under the name of the Juxtafacet cyst by the several researchers. They put forward that the synovial cyst originated from the synovial joint. But, they failed to clarify the pathophysiology of the formation of the ganglion cyst. In this case report, we reported a 67-year-old male patient was referred to the emergency from another center with the complaint of a left leg pain and weakness in the left foot and patient was treated with microchirurgical technique. His patological examination was evaluated a ganglion cyst. We have discussed and explained the pathophysiology of the formation of a ganglion cyst derivered from a synovial cyst. And separately, we have presented the spinal cysts by grouping them under a new classification called a cystic formation of the soft tissue attachments of the mobile spine as well as dividing them into sub-groups.

    A cutaneous ciliated cyst is a rare entity found predominantly in the lower extremities and perineal region of young females. Although initially described by Hess in 1890, the present day term, "cutaneous ciliated cyst," was proposed by Farmer in 1978 and includes a wide array of cyst types. Despite their typical female predominance and location, many have described cutaneous ciliated cysts in males and atypical locations. In addition, Mullerian cysts in the posterior mediastinum and the retroperitoneum have been reported. To date, only 40 cases have been reported in the literature of a Mullerian-type, cutaneous ciliated cyst. Here, we report a case of 13-year-old female with one in the gluteal cleft, initially presenting as a pilonidal cyst. We also discuss the differential diagnosis of pediatric sacrococcygeal lesions and pathogenesis of a Mullerian-type, cutaneous ciliated cyst. PMID:23913265

    The purpose of this study was to accurately analyze the radiographic characteristics of dentigerous cyst (DC) with multiplanar images of cone beam computed tomography (CBCT). Thirty eight radiographically and histopathologically proven cases of DCs were analyzed with panoramic radiograph and CBCT, retrospectively. The radiographic CT pattern, symmetry of radiolucency around the unerupted tooth crown, ratio of long length to short length, degree of cortical bone alternation, effects on adjacent tooth, and cyst size were analyzed. Relative frequencies of these radiographic features were evaluated. In order to compare the CBCT features of DC with those of odontogenic keratocyst (OKC), 9 cases of OKCs were analyzed with the same method radiographically. DCs consisted of thirty unilocular cases (79.0%), seven lobulated cases (18.4%) and one multilocular case (2.6%). Eight were asymmetric (21.0%) and thirty were symmetric (79.0%). Maxillary DC showed rounder shape than mandibular DC (L/S ratio; maxilla 1.32, mandible 1.67). Alternations of lingual cortical bone (14 cases, 48.2%) were more frequent than those of buccal side (7 cases, 24.1%). CBCT images of DC showed definite root resorption and bucco-lingual tooth displacement. These findings were hardly observed on panoramic radiographs of DCs. Comparison of CBCT features of DC with those of OKC showed several different features. CBCT images of DC showed various characteristic radiographic features. Therefore, CBCT can be helpful for the diagnosis of DC radiographically.

    International Nuclear Information System (INIS)

    A five-year-old domestic longhair was presented with hind-limb ataxia and some degree of incontinence of two weeks' duration. An enlarged spinal canal from the twelfth thoracic (T-12) vertebra to the third lumbar (L(3)) vertebra was identified on survey radiographs. An intradural-extramedullary cavity at the twelfth (T-12) and thirteenth (T-13) thoracic vertebrae, filled with contrast material, was demonstrated on myelography. A left-sided hemilaminectomy was performed over this region, and a subarachnoid cavitation or cyst was found to be the cause of the severe spinal-cord compression. The cyst was drained. The cat showed improvement in the neurological signs during the first three weeks postoperatively. Six months later no neurological deficits were identified on follow-up examination

    Full Text Available Primary hydatid disease of spine is rare and spinal hydatitosis constitute only 1% of all hydatitosis. We report a case of recurrent primary intraspinal extradural hydatid cyst of the thoracic region causing progressive paraparesis. The patient was operated 16 years ago for primary spinal hydatid disease involvement and was instrumented dorsally for stabilization. The magnetic resonance imaging (MRI of thoracic spine showed a cystic lesion at T11-12 level and compressed spinal cord posterolaterally. Intraspinal cyst was excised through T11-12 laminectomy which made formerly. The early postoperative period showed a progressive improvement of his neurological deficit and he was discharged with antihelmintic treatment consisting of albendazole and amoxicillin-sulbactam combination.

  1. Magnetic resonance imaging for postoperative maxillary cyst

    International Nuclear Information System (INIS)

    Magnetic resonance images of 47 patients with postoperative maxillary cyst were analyzed for size, location, and signal intensity. The smallest cyst was confirmed at surgery to be 1 cmx1 cmx1 cm and the largest 5 cmx5 cmx5 cm. The cysts were usually found in the superomedial and inferomedial parts of the maxillary sinus (44%). Many patients (60%) had multiple cysts or bilateral cysts (30%). In most the signal intensity was low in the T1-weighted SE (500/40) images and high in the T2-weighted SE (2000/80) images. Cysts with a hemorrhagic component, though rare, showed high signal intensity in both T1-and T2-weighted images. (author)

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

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

Aortic wall is a very unusual site for the hydatid cysts. To the best of our knowledge, this is the first reported case of hydatid cyst located within the aortic arch lumen. Patient underwent ascending aortic and hemiarch replacement under hypothermic circulatory arrest and removal of the cyst. Patient had an uneventful recovery and has been on follow-up. Although the literature data are very limited, we believe that the aortic procedure of choice should be graft interpositon rather than patch repair. PMID:17215134

    We reviewed the clinical, radiological and surgical findings in patients with both pituitary adenoma and Rathke's cleft cyst. We retrospectively selected patients with both lesions from the 374 patients in whom a sellar/juxtasellar lesion was detected on MRI at 1.5 tesla. All patients received intravenous contrast medium. Concomitant pituitary adenoma and Rathke's cleft cyst were found in eight patients (2.1 %). The frequency of the combination was 3.5 % of pituitary adenomas and 11 % of Rathke's cleft cysts. Symptoms were always due to the adenoma, secreting adrenocorticotrophin in two patients and growth hormone in six. The adenoma was larger in five patients, and the cyst in three. The cysts gave variable signal. The adenoma was adjacent to the cyst in seven patients, and enclosed it in the other patient. As a result of experience with MRI, concomitant pituitary adenoma and Rathke's cleft cyst are now known not to be as rare as thought previously. When a nonenhancing cyst-like structure is demonstrated in a patient with pituitary adenoma, the possibility of a coexisting Rathke's cleft cyst should be considered. (orig.)

    Full Text Available Foregut cysts are various congenital lesions originated from emberyonic foregut. Bronchogenic, enterogenous and neuroenteric cysts are the most frequent forms of foregut cysts. They create different clinical symptoms based on their location. Enterogenous cysts comprise 4-5 percent of posterior mediastinal cysts and include esophageal, gastric and enteric cysts. A 61 year old woman referred to surgical clinic with dysphasia and regurgitation 6 months ago whose illness aggravared over the last 3 months. In physical examination, a lesion was seen in the right site of posterior mediastinum. Surgical excision was done and a ciliated columnar epithelium with two thin muscular layers were reported in pathology. In reality, the distinction between esophageal and bronchogenic cysts is not always clear. Both cysts present in mediastinum and their epithelial tissues are non-specific, however presence or lack of muscle layer in cyst-wall, proximity to gastrointestinal tract or tracheobronchial tree, adaption of clinical symptoms with paraclinic results and observations during surgical procedure can reveal certain diagnosis.

    A radiologic study of 139 dentigerous cysts (128 patients) indicated the followings: 1. There was higher incidence in males (62.99%) than in females (37.01%). The most common age group was 11-20 years and the average age was 23.6 years. 2. The most common clinical symptoms was swelling of the jaws (49 cases, 33.09%), and no symptoms was presented in 26 cases (18.71%). 3. Dentigerous cysts were found to be slightly more common in the maxilla (53.24%) than in the mandible (46.76%) and there was almost no difference in occurrence between right and left side. The maxillary supernumerary tooth was the most frequent site of the dentigerous cyst and no dentigerous cyst was found to be related to a deciduous tooth. 4. The most common radiographic findings was root resorption of the adjacent teeth (33.09%), and the central dentigerous cysts were 78 cases (56.12%), the lateral dentigerous cysts were 61 cases (43.88%). 5. The increased radiolucency at the crown portion of the tooth in a cystic cavity was seen in 44 cases (31.65%), and a case of dentigerous cyst was found in a edentulous patient, and 16 cases of multiple dentigerous cysts were found in 5 patients. 6. The ameloblastic changes in 8 cases, the keratinization of the cyst wall in 2 cases, and a case of epidermoid carcinoma were confirmed microscopically.

    Retrorectal hamartomas or tail gut cysts are rare congenital anomalies most commonly seen in a retrorectal location; most common in middle aged women. This article describes the radiological appearance in two cases of tail gut cysts in males, one a child with a visible perianal swelling since birth and the other, a 72-year-old man with symptoms for one week. In both, the tailgut cysts were in a right perirectal location. Presentation in such a location in males, at extremes of age, is unusual for tailgut cysts. PMID:20607026

    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 Ussi...

  17. Extra-articular soft tissue ganglion cyst around the knee: focus on the associated findings

    International Nuclear Information System (INIS)

    The aim of this study was to evaluate MR imaging findings of the associated findings in surrounding tissues of the extra-articular soft tissue ganglion cysts around the knee. We retrospectively reviewed MR images of 30 patients who had surgically confirmed extra-articular soft tissue ganglion cysts around the knee with focus on the associated findings in surrounding tissues, such as muscle, subcutaneous fat, bone, and nerve. The most common associated finding was the visualization of channel between ganglion cyst and the joint, which was demonstrated in 20 cases (continuous type in 12 cases and discontinuous type in 8 cases). Other associated findings were seen in 15 cases; pericystic edema (n=9), bony remodelling (n=3), and nerve involvement (n=3). The bony remodelling involved the proximal metaphysis of tibia in all 3 cases. Two patients with nerve involvement had deep peroneal nerve in subacute phase and one involved common peroneal nerve in chronic phase. The MR imaging is a useful imaging modality to evaluate the associated findings in extra-articular soft tissue ganglion cysts around the knee. The evaluation of these associated findings is helpful for the differentiation of ganglion cysts from other cystic lesions around the knee. (orig.)

    Symptomatic sacral perineural cysts are uncommon. Several hypotheses have been proposed to explain the etiologies of perineural cysts, but the accurate etiologies remain unclear. We experienced two cases of symptomatic sacral perineural cysts (Tarlov cysts) in one family, who presented with perianal paresthesia. Both of them were operated and postoperatively their symptoms were disappeared immediately. We experienced the excellent treatment outcome with the surgical management of symptomatic perineural cysts in the sacral region. We assume that the theory of congenital origin including a familial tendency is the most plausible of the hypotheses that have been proposed. PMID:19096672

    A variety of cystic lesions may develop in spinal canal. These cysts can be divided into intramedullary, intradural, extradural, cervical, thoracic, lumbar, and sacral cysts according to anatomical presentation, as well as arachnoid, meningeal, perineural, juxtafacet, discal, neurenteric cysts, and cyst-like lesions according to different etiologies. Mechanisms of initiation and growth vary for different cysts, such as congenital, trauma, bleeding, inflammatory, instability, hydrostatic pressure, osmosis of water, secretion of cyst wall, and one-way-valve effect, etc. Up to now, many treatment methods are available for these different spinal canal cysts. One operation method can be applied in cysts with different types. On the other hand, several operation methods may be utilized in one type of cyst according to the difference of location or style. However, same principle should be obeyed in surgical treatment despite of difference among spinal canal cysts, given open surgery is melely for symptomatic cyst. The surgical approach should be tailored to the individual patient.

    To evaluate the CT findings of ruptured corpus luteal cysts. Six patients with a surgically proven ruptured corpus luteal cyst were included in this series. The prospective CT findings were retrospectively analyzed in terms of the size and shape of the cyst, the thickness and enhancement pattern of its wall, the attenuation of its contents, and peritoneal fluid. The mean diameter of the cysts was 2.8 (range, 1.5-4.8) cm; three were round and three were oval. The mean thickness of the cyst wall was 4.7 (range, 1-10) mm; in all six cases it showed strong enhancement, and in three was discontinuous. In five of six cases, the cystic contents showed high attenuation. Peritoneal fluid was present in all cases, and its attenuation was higher, especially around the uterus and adnexa, than that of urine present in the bladder. In a woman in whom CT reveals the presence of an ovarian cyst with an enhancing rim and highly attenuated contents, as well as highly attenuated peritoneal fluid, a ruptured corpus luteal cyst should be suspected. Other possible evidence of this is focal interruption of the cyst wall and the presence of peritoneal fluid around the adnexa.

  15. Orbital dermoid and epidermoid cysts: Case study

    Directory of Open Access Journals (Sweden)

    Veselinović Dragan

    2010-01-01

    Full Text Available Introduction. Dermoid and epidermoid cysts of the orbit belong to choristomas, tumours that originate from the aberrant primordial tissue. Clinically, they manifest as cystic movable formations mostly localized in the upper temporal quadrant of the orbit. They are described as both superficial and deep formations with most frequently slow intermittent growth. Apart from aesthetic effects, during their growth, dermoid and epidermoid cysts can cause disturbances in the eye motility, and in rare cases, also an optical nerve compression syndrome. Case Outline. In this paper, we described a child with a congenital orbital dermoid cyst localized in the upper-nasal quadrant that was showing signs of a gradual enlargement and progression. The computerized tomography revealed a cyst of 1.5-2.0 cm in size. At the Maxillofacial Surgery Hospital in Niš, the dermoid cyst was extirpated in toto after orbitotomy performed by superciliary approach. Postoperative course was uneventful, without inflammation signs, and after two weeks excellent functional and aesthetic effects were achieved. Conclusion. Before the decision to treat the dermoid and epidermoid cysts operatively, a detailed diagnostic procedure was necessary to be done in order to locate the cyst precisely and determine its size and possible propagation into the surrounding periorbital structures. Apart from cosmetic indications, operative procedures are recommended in the case of cysts with constant progressions, which cause the pressure to the eye lobe, lead to motility disturbances and indirectly compress the optical nerve and branches of the cranial nerves III, IV and VI.

    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

    Full Text Available Pilonidal cysts and sinuses are described as dermoid cysts which contain follicles of hairs and sebaceous glands. They clinically present as a classic case of inflammation which comes with pain, local infection and redness. The origin of pilonidal disease remains controverse. There are many hypothesis as lack of hygiene on the affected area and a penetration and growth of a hair in the subcutaneus tissue caused by constant friction or direct trauma on the damaged area. The option for clinical treatment is very frequent. However, taking into consideration the incidence and the possibility of recidive, surgical treatment is presently recommended. Complications include cellulitis and abscess formation. Pilonidal cysts are mostly found on the sacral region. In the literature is found description of pilonidal cysts on the penis, interdigital region on the hands as well as on the cervical region. We present a case of pilonidal cyst located on the vault biparietal region, without malignant degeneration.

    Hydatid cyst (HC) in mediastinum is very rare. To the best of our knowledge, a case with multiple HCs in mediastinum is not reported already. We herein report a case of multiple HCs of the mediastinum and liver in a - 50 year-old woman presented with chest pain, cough and dyspnea for about two years. She had been treated for tuberculosis for 20 years. Chest CT scan showed multiple cysts in posterior mediastinum and one cyst in left lobe of liver. Via right posterolateral thoracotomy, multiple cysts were excised in mediastinum. And then, hepatic left lobe cyst was removed trans-diaphragmatically. Histopathologic examination confirmed HCs. Despite its rarity, primary HCs should be considered in the differential diagnosis of mediastinal multiple cystic lesions in endemic regions. PMID:20067057

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

    2011-01-01

    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.

The male to female ratio was 1:5, and the age distribution was 5 cases in adult and one in 5 year old girl. 2. The most frequent symptom was abdominal pain, which was followed by palpable mass and thin jaundice in frequency order. 3. All of them were type A' of Kimura classification, morphologically. 4. Of 5cases, 2 cases showed markedly distended gallbladder. Remaining one case was received cholecystectomy 15 years before this study. 5. Associated choledocholithiasis was reported to be rare, but we found 2 cases of multiple stones and 2 cases of single stone. 6. Combined other lesions were found in 3 cases - - chronic pancreatitis,pancreatic cancer, and ascites by bile leakage. 7. Ultrasonography can easily evaluate intrahepatic bile duct as well as extrahepatic bile duct, so the authors correctly diagnosed choledochal cyst type A' of Kimura classification by ultrasonography alone in 3 cases among 6

    Squamous cell carcinoma arising in an odontogenic cyst is uncommon. The diagnosis of carcinoma arising in a cyst requires that there must be an area of microscopic transition from the benign epithelial cyst lining to the invasive squamous cell carcinoma. We report a histopathologically proven case of squamous cell carcinoma arising in a residual mandibular cyst in a 54-year-old woman.

    Mesenteric cysts are rare intra-abdominal lesions with variable clinical symptoms and signs that make pre-operative diagnosis difficult. Optimal treatment is surgical excision of the cyst with laparotomy or laparoscopy. We present a case of mesenteric cyst that was misdiagnosed as para-ovarian cyst and managed laparoscopically by gynaecologists.

    To report the effectiveness of Minocin sclerotherapy in the treatment of renal cysts. We performed minocin sclerotherapy to 19 patients with 21 renal cysts composed of 17 cases of solitary renal cyst and three cases of multiple renal cyst and one case of polycystic kidney confirmed by ultrasound and CT. After aspiration of cyst fluid, if the amount was less than 50 ml, 500 mg of minocin was mixed with 3 ml of normal saline, if more than 50 ml, 1000 mg of minocin mixed with 5 ml of normal saline were injected, and each case was followed-up over 3 months by ultrasound. Of all 21 renal cysts, 14 cases were followed-up three months after minocin sclerotherapy. In 12 of 14 case, the size of the cysts decreased by 10% or collapsed completely. Of the remaining two cases, one collapsed after 6 months while the other recurred after 6 months. Three cases were followed up after 20 months and only one of them recurred. 19 of all 21 cases(91%) were cured, and two of 21 cases(9%) were recurred. Pain was the only complaint and four of 10 cases needed analgesics. Sclerotherapy with minocin has low recurrence-rate and low complication, and relatively early high cure-rate.

    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. PMID:24790764

    Full Text Available Abstract Background It is acknowledged that total cyst excision is a safe and ideal surgical treatment for congenital biliary duct cyst, compared to simple internal drainage. The aim of this study was to determine the optimal operation occasion and the effect of laparoscopy on congenital biliary duct cyst based upon total cyst excision. Methods From January 2002 to January 2011, 217 patients were admitted to Southwest Hospital for congenital biliary duct cyst. To determine the optimal surgery occasion, we divided these subjects into three groups, the infant group (age ≤ 3 years, the immaturity group (3 18 years, and then evaluated the feasibility, risk and long-term outcome after surgery in the three groups. To analyze the effect of laparoscopic technique on congenital biliary duct cyst, we divided the patients into the laparoscopy and the open surgery groups. Results Among the three groups, the morbidity from cholangiolithiasis before surgical treatment had obvious discrepancy (p 0.05. Similarly, no significant discrepancy was observed in the morbidity from postoperative complications or long-term postoperative complications (p > 0.05 between the laparoscopic and the open surgery groups. Conclusions We conclude that total cyst excision should be performed as early as possible. The optimal treatment occasion is the infant period, and laparoscopic resection may be a new safe and feasible minimally invasive surgery for this disease.

  14. CT Imaging Findings of Ruptured Ovarian Endometriotic Cysts: Emphasis on the Differential Diagnosis with Ruptured Ovarian Functional Cysts

    International Nuclear Information System (INIS)

    The purpose of this study is to assess the prevalence of abnormal CT findings in patients with surgically proven ruptured endometriotic cysts, as compared with those abnormal CT findings of ruptured ovarian functional cysts. This study included 13 retrospectively identified patients with surgically confirmed ruptured ovarian endometriotic cysts and who had also undergone preoperative CT scanning during the previous seven years. As a comparative group, 25 cases of surgically confirmed ruptured ovarian functional cysts were included. We assessed the morphologic features of the cysts and the ancillary findings based on CT. For the endometriotic cysts, the mean maximum cyst diameter was significantly larger than that of the functional cysts (70.1 mm versus 36.4 mm, respectively, p < 0.05). The endometriotic cysts frequently had a multilocular shape and a thicker cyst wall, as compared to that of functional cysts, and these differences were statistically significant. Among the ancillary findings, endometriotic cysts showed a significantly higher prevalence of loculated ascites, ascites confined to the pelvic cavity without extension to the upper abdomen, and peritoneal strandings and infiltrations (p < 0.05). Although 11 of the 25 cases of functional cysts showed active extravasation of contrast material at the ovarian bleeding site, only one of 13 cases of endometriotic cysts showed active extravasation. The diagnosis of ruptured endometriotic cyst should be suspected for a woman in whom CT reveals the presence of multilocular or bilateral ovarian cysts with a thick wall and loculated ascites confined to the pelvic cavity with pelvic fat infiltrations

    The resting cyst plays an important role in the life cycle of certain dinoflagellates. Cyst formation is of great significance to populations in terms of perseverance and dispersal. Dinoflagellates producing cysts spend much more time in the sediment than in the water column, and studies on cysts help to uncover dinoflagellate diversity. Cyst diversity and abundance within sediments can reflect the history of overlying dinoflagellates and environmental conditions, and thus serve as a historic...

    Orthokeratinized odontogenic cyst (OOC) is a developmental cyst of jaw and was initially considered by the World Health Organization (1992) as the uncommon orthokeratinized variant of odontogenic keratocyst (OKC). However, studies have shown that OOC has peculiar clinicopathologic aspects when compared with other developmental odontogenic cysts, especially OKC. So orthokeratinized odontogenic cyst now stands out to be a distinct entity. Clinically, it occurs as a single cyst, shows a predilec...

    This article reviews what is known about ganglion cyst formation, natural history (50% of cysts will spontaneously resolve), diagnosis, and management of this common malady. Although the exact mechanism of cyst formation is unknown, most current theories hold that extra-articular mucin “droplets” coalesce to form the main body of the tumor. Only subsequently are the “cyst wall” and pedicle (connecting the cyst to a nearby synovial joint) formed. Treatment options include watchful waiting, non...

    This case report describes a patient with severe back pain and radiculopathy. She was found to have a facet cyst within the lumbar spine that appeared to contain calcium on MRI and CT. Upon aspiration the cyst was found to contain calcium ammonium phosphate (struvite) and calcium phosphate (hydroxyapatite). Ammonia production in the presence of urease-producing bacteria is responsible for the production of struvite in the human body. We postulate that there was a prior infection of the facet with urease-producing bacteria, thus accounting for the production of the struvite within the facet cyst. (orig.)

    Full Text Available The first prenatal detection of an ovarian cyst was by Valenti in 1975. Since then antenatal and neonatal ovarian cysts are encountered more frequently due to the improvement of imaging techniques as well as routine antenatal ultrasound scanning. We discuss here the laparoscopic management of three cases of neonatal ovarian cysts. This approach is well tolerated by neonates, and it may overcome the controversy between the ′wait and see′ policy and early surgical intervention, as laparoscopy has both diagnostic and therapeutic value with minimal morbidity, and ovarian salvage whenever possible.

  10. Evaluation of bone scintigraphy in differential diagnosis of benign bone tumors

    International Nuclear Information System (INIS)

    Bone scintigraphy with sup(99m)Tc-phosphate compounds was evaluated from the analysis of 71 consecutive cases of various benign bone tumors whether the scintigrams could be helpful in their differential diagnosis. The characteristics of the scintigraphic image at the site of bone lesions were noticed as being marked (++), moderate (+) and poor or minimal (-), according to the degree of accumulation of the radioactivity. Fibrous dysplasia (8 among 9 cases) as well as aneurysmal bone cyst (3 among 4 cases) had strong tendency of marked accumulation. Poor or minimal accumulation was observed in almost all of the lesions of nonossifying fibroma including fibrous cortical defect (6 all cases), solitary bone cyst (4 among 6 cases) and enchondroma (3 among 4 cases). Moderate accumulation was said to be non-specific, since it could be encountered in any types of benign bone tumors. But it was noticed that the majority of the bone lesions of eosinophilic granuloma (7 among 9 cases) showed moderate accumulation and the scintigraphic evidence of the skeletal disease appeared to be less extensive than the roentgenogram. These scintigraphic characteristics realized in some benign bone tumors occasionally played an important role in clinical diagnosis, especially in the cases atypical on roentgenographic findings. Several instructive cases whose final diagnosis was strongly linked to the scintigraphic informations were demonstrated. (author)

Case Presentation This case report presents multiple COC, which involved the maxillary bone and sinus in a 30-year-old man. Several of these lesions were cystic, while the others were neoplastic in type, and the lesions were removed surgically. Discussion Based on a literature review available on this topic in English, our case study was found to be the first one with multiple COC, showing both the cystic and neoplastic histopathological variant. Considering the high rate of recurrence of neoplastic COC, the patients should benefit from a long follow-up after treatment.

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

    Full Text Available Cardiac hydatidosis is rare presentation of body hydatidosis. Incidence of cardiac involvements range from 5% to 5% of patients with hydatid disease. Most common site of hydatid cyst in heart is interventricular septum and left ventricular free wall. Right ventricular free wall involvement by cyst that ruptured to pericardial cavity is very rare presentation of hydatid cyst. Cardiac involvement may have serious consequences such as rupture to blood steam or pericardial cavity. Both the disease and its surgical treatment carry a high complication rate, including rupture leading to cardiac tamponade, anaphylaxis and also death. In the present report, a 43-year-old man with constrictive pericarditis secondary to a pericardial hydatid cyst is described.

    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

    The purpose of this study was to investigate the surgical outcomes and to determine indicators of the necessity of surgical intervention. Twelve consecutive patients harboring symptomatic sacral perineural cysts were treated between 1995 and 2003. All patients were assessed for neurological deficits and pain by neurological examination. Magnetic resonance of imaging, computerized tomography, and myelography were performed to detect signs of delayed filling of the cysts. We performed a release of the valve and imbrication of the sacral cysts with laminectomies in 8 cases or recapping laminectomies in 4 cases. After surgery, symptoms improved in 10 (83% of 12 patients, with an average follow-up of 27 months. Ten patients had sacral perineural cysts with signs of positive filling defect. Two (17% of 12 patients experienced no significant improvement. In one of these patients, the filling defect was negative. In conclusion, a positive filling defect may become an indicator of good treatment outcomes.

Two (17%) of 12 patients experienced no significant improvement. In one of these patients, the filling defect was negative. In conclusion, a positive filling defect may become an indicator of good treatment outcomes. PMID:16508691

    2009-01-01

    Full Text Available A 21-year-old male with developmental delay presented with abdominal pain of two days' duration. He was afebrile and his abdomen was soft with mild diffuse tenderness. There were no peritoneal signs. Plain x-ray demonstrated a large air-filled structure in the right upper quadrant. Computed tomography of the abdomen revealed a 9×8 cm structure adjacent to the hepatic flexure containing an air-fluid level. It did not contain oral contrast and had no apparent communication with the colon. At operation, the cystic lesion was identified as a duplication cyst of the sigmoid colon that was adherent to the right upper quadrant. The cyst was excised with a segment of the sigmoid colon and a stapled colo-colostomy was performed. Recovery was uneventful. Final pathology was consistent with a duplication cyst of the sigmoid colon. The cyst was attached to the colon but did not communicate with the lumen.

    International Nuclear Information System (INIS)

    Objective: To evaluate and follow the patients who underwent thyroglossal cyst and ducts excision (Sistrunks operation) regarding the recurrence and complications at our institution. Methodology: During the period between May 2010 and May 2013, 88 patients underwent thyroglossal cyst excision. These were assessed preoperatively clinically and by sonographic imaging and thyroid nuclear scanning in the out patient department. Post operative care, follow up and histopathological review after discharge was done up to 3 years for some patients. Results: 88 patients were included in this study; 49 were female and 39 males with female-male ratio 1.25:1. Mean age was 4.5 years (range 1.5-9). All of them underwent Sistrunks operation with the excision of the midportion of the hyoid bone. Mean hospital stay was 3 days (range 1-5 days). Three patients (3.4%) developed hematoma and swelling at site of the operation and were managed conservatively. Another 5 patients (5.6%) developed wound infection at the site of surgery and were managed by antibiotics and drainage of the abscess, 6 patients (6.8%) had recurrence of the cyst about 6 months after the surgery. Conclusion: Thyroglossal cyst surgery is common in pediatric surgical practice. Recurrence rates, infection rates and other complications in our hospital were within the global range and our results were acceptable. (author)

    Full Text Available Neonates may present with various causes of stridor. Nasopharyngeal cysts are rare congenital lesions causing difficulty in breathing. Differential diagnosis of nasopharyngeal cysts include thornwalds cyst, rathke cleft and craniopharyngioma, teratoma, epidemoid cysts, dermoid cyst, nasopharyngeal encephalocele, infected cyst and branchial cyst. Though branchial cysts are very rarely present in nasopharynx, they are easy to diagnose on MRI and fall under the category of preventable causes of neonatal stridor. Their surgical excision is the treatment of choice but sometimes owing to the other prematurities present the neonate period is not always the best time to operate. We report a case of a newborn child with nasopharyngeal branchial cyst presenting with stridor and managed conservatively with aspiration

    Iris cysts can arise from iris pigment epithelium or stroma. We present 3 cases of iris cysts which have been managed in different ways. 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

    Full Text Available Pericardial cysts are rare benign congenital mediastinal lesions. It accounts 30% of all mediastinal cysts. They are usually asemptomatic. They can produce the compression of the mediastinal structures typically caused the symptoms of dyspnea, thoracic pain, tachicardia and cough due to the unusual large size of the cyst. It can performed symptoms of lung atelectasia. The case was a sixty-five years old woman followed with a diagnosis of COPD for seven years. The patient was admitted to our center with the diagnosis of elevation of the right hemidiaphragm on chest radiography. The computed tomography revealed a cystic lesion adjacent to the right hemidiaphragm and cyst excision was performed via right thoracotomy. Patient%u2019s postoperative clinical findings indicated that the symptoms of COPD regressed completely and the patient did not require any further bronchodilator therapy. The aim of this case report is to demonstrate that the pericardial cysts can be missed in chest radiographs and impression of cysts may cause COPD like symptoms in these patients.

    Full Text Available Introduction: Hydatid cyst of the adrenal gland is extremely rare even in generalized hydatid disease, with less than 20 cases reported in world literature including those found in autopsy. Case outline: The authors present the second case of the adrenal gland hydatid cyst described in Serbian literature, in 52-year old woman. During the investigation for the epigastric pain by ultrasonography and computed tomography, calcified cyst of the sixth segment of the liver, 44Ч39 mm in diameter, was diagnosed. However, during an open surgery, it turned out to be the cyst of the right adrenal gland. The cyst as well as the entire adrenal gland was removed. The hydatid nature of the cyst was confirmed by histological examination. The postoperative recovery was uneventful. The patient has remained symptom-free over two years after the surgery. Conclusion: To the best of our knowledge, this is the second case reported in Serbian and 18th case published in world literature.

    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.

    2015-01-01

    Introduction: Intra-articular ganglion cysts of the knee joint are rare occurrences. They are usually encountered as incidental findings in magnetic resonance imaging (MRI), or in arthroscopy. They may originate from both the cruciate ligaments and the menisci, from the popliteus tendon and alar folds, infrapatellar fat pad of Hoffa, and subchondral bone cysts. Those arising from the Hoffa’s fat pad, usually present as palpable mass at anterior aspect of the knee joint. We report a case of intraarticular ganglion cyst of knee arising from the infrapatellar fat pad and protruding anterolaterally through retinacular rent into the subcutaneous plane. Case Report: A 19-year-old young man, presented with a painless gradually increasing swelling at the anterior aspect of left knee of 9 months duration. MRI scan revealed a multilobulated, cyst with septations within the anterior aspect of the knee joint, just inferolateral to the patella, with deep extension into the infrapatellar fat pad, and superficial extension into the subcutaneous space across the retinaculum. After diagnostic arthroscopy, we performed an open excision of the cystic mass and confirmed the retinacular rent pre-operatively. Conclusion: Arthroscopic resection and debridement is the gold standard treatment in ganglion cyst of the knee. However, a subcutaneous extension may lead to incomplete arthroscopic resection: Leaving behind the residual tissue which may cause recurrence. Therefore, proper pre-operative evaluation of MR images of these cases is very important. PMID:27299075

    Full Text Available Ovarian cysts are fluid filled sacs inside the ovary that are common among women during their reproductive years. Most cysts are harmless and go away without any treatment, but some may cause problems such as rupturing, bleeding, or pain; and surgery may be required to remove the cyst(s. When the follicles (sacs in the ovaries do not rupture, they form small cysts called 'simple cysts'. These form whenever ovary produces too much of estrogen hormone. 'Dermoid cysts' & 'chocolate cysts' are other types of cysts. 'Large' or 'pathological cysts' can occur in about 5% of women during their reproductive years. Management of Ovarian cyst through surgery is available to meet urgent medical need, but huge challenges remain to treat by medicines. Ayurveda, (the Science of Life which is the oldest well documented ancient Indian System of medicine is giving new ray of hope in the management of ovarian cyst (Kaphaj Granthi vikaar.

    Objective To investigate which structural MR abnormalities discriminate symptomatic knee osteoarthritis (OA), taking co-occurrence of abnormalities in all compartments into account. Methods The Netherlands Epidemiology of Obesity (NEO) study is a population-based cohort aged 45–65 years. In 1285 participants (median age 56 years, 55% women, median body mass index (BMI) 30 kg/m2), MRI of the right knee were obtained. Structural abnormalities (osteophytes, cartilage loss, bone marrow lesions (BMLs), subchondral cysts, meniscal abnormalities, effusion, Baker's cyst) at 9 patellofemoral and tibiofemoral locations were scored following the knee OA scoring system. Symptomatic OA in the imaged knee was defined following the American College of Rheumatology criteria. Logistic ridge regression analyses were used to investigate which structural abnormalities discriminate best between individuals with and without symptomatic OA, crude and adjusted for age, sex and BMI. Results Symptomatic knee OA was present in 177 individuals. Structural MR abnormalities were highly frequent both in individuals with OA and in those without. Baker's cysts showed the highest adjusted regression coefficient (0.293) for presence of symptomatic OA, followed by osteophytes and BMLs in the medial tibiofemoral compartment (0.185–0.279), osteophytes in the medial trochlear facet (0.262) and effusion (0.197). Conclusions Baker's cysts discriminate best between individuals with and without symptomatic knee OA. Structural MR abnormalities, especially in the medial side of the tibiofemoral joint and effusion, add further in discriminating symptomatic OA. Baker's cysts may present as a target for treatment.

    To evaluate the radiologic findings of intraspinal epidural arachnoid cyst. Six patients with surgically proven intraspinal epidural arachnoid cyst were included in this study. Four were free of specific past history, but two had a history of trauma. All underwent examination by plain radiogr4aphy, CT-myelography and MRI, and the following aspects were retrospectively analysed:vertebral pressure erosion, interpedicular distance, enlargement of neural foramina, as seen on plain radiograph, contrast-filling and lateral bulging of lesions through neural foramina on CT-myelograph, and signal intensity, size and shape of margin and epidural fat pattern, as seen on MRI. Three of four congenital intraspinal epidural arachnoid cysts were single in the thoracolumbar region, while in the other case, there were multiple cysts in the mid-and lower thoracic regions. Cysts were equivaleut in size to between four and six vertebral bodies. Plain radiographic findings of pedicular pressure erosion, widened interpedicular distance, and bilateral neural foraminal enlargement of several contiguous vertebrae were observed in all four cases. One showed posterior vertebral scalloping. On CT-myelograph, a contrast-filled cystic lesion occupying the posterior epidural space, with lateral bulging through neural foramina and anterior displacement of the contrast-filled thecal sac, was seen. On MRI, longitudinally elongated, well-demarcated cysts were seen to be present in the posterior epidural space;their signal intensity was the same as in CSF. An epidural fat cap pattern enveloping the upper and lower ends of the cysts was apparent in all cases. In two cases, traumatic intraspinal epidural arachnoid cysts were situated in the thoracolumbar and lumbosacral region, respectively, near a previously injured region and were smaller (equivalent to the height of three vertebral bodies). CT-myelograph and MRI showed that their effect on the thecal sac was compressive only. When pressure erosion of

  19. Percutaneous alcohol sclerotherapy for symptomatic congenital cysts

    International Nuclear Information System (INIS)

    Twenty patients with symptomatic congenital cysts in the liver, kidney, thyroid, and lower neck underwent, ultrasound guided percutaneous aspiration through a drainage catheter with temporary instillation of 95% ethanol into the cyst. Our procedure was based on the method as described by Bean and Rodan(16) in 1985. Additionally, two other steps were added to prevent the dilutional effect of residual cyst fluid. One was the preliminary washing of the cyst with alcohol. The other was to treat with 30% replacement of alcohol every 10 minutes during the treatment secession. Minor complications of transient temperature elevation and haziness occurred, but no major complications were encountered. After the alcohol treatment follow up examinations were performed with computed tomography or ultrasonography at 6 weeks, 6 months, 9 months and 15 months. Although there was diminished size, recurrence was noted in 6 of twenty patients(30%) at 6 weeks and one of twenty patients(5%) at 6 months. There was no recurrence at 9 months and 15 months. The results indicated that percutaneous aspiration and alcohol sclerotherapy are safe and effective therapy for symptomatic congenital cysts

    A cystic lesion adjacent to the dens with compression of the lower portion of the medulla oblongata was found on MRI in a 75-year-old male patient with a 2-month history of occipital pain and gait disturbance. Clinically, the patient showed mild tetraparesis, signs of spinal ataxia and symmetrical hyperreflexia. Following subtotal removal of the cyst via left-sided suboccipital craniotomy and left-sided hemilaminectomy of C1 the lesion was classified as synovial cyst on histopathological examination. Postoperatively, the quadriparesis almost completely subsided and the patient is currently doing well, 33 months after surgery. Synovial or ganglion cysts adjacent to the atlantoaxial articulation with ventral compression of the cervicomedullar cord represent rare surgical or radiological entities. Atlantoaxial synovial cysts have no typical radiographic appearance or specific neurological symptoms so that they are frequently misdiagnosed as intraspinal- or skull base tumour, rheumatoid lesion or ectatic vertebral artery. Since no ensuing complications or recurrences have been encountered in cases of incompletely removed cysts the less invasive operative approaches should be used to avoid destabilisation and subsequent additional surgical procedures.

    Full Text Available Surgical options for suprasellar arachnoid cyst are cystoperitoneal shunt, craniotomy fenestration and endoscopic fenestration. Endoscopic management has been found to be safe and effective. We report our experience with endoscopic management in 12 (male five, female seven; age range 8 months to 42 years patients with suprasellar arachnoid cyst. The endoscopic procedure included lateral ventricle puncture by precoronal burr hole and superior and inferior wall of the cyst was communicated with the lateral ventricle and the interpeduncular cistern respectively. All patients had hydrocephalus. Four pediatric patients had macrocephaly. All adult patients had visual disturbances. One adult patient presented with psychomotor disturbance along with features of raised intracranial pressure. All cases improved following endoscopic treatment. There were no complications or death. One patient required VP shunt. Postoperative MRI showed significant reduction in cyst volume in 11 patients. Follow-up ranged from 6 months to 6 and a half years. Our study suggests that endoscopic technique is a safe and effective alternative treatment for suprasellar arachnoid cyst. It prevents complications such as subdural effusion and intracranial hematoma, which are not uncommon with craniotomy fenestration.

  2. Postmenopausal Vaginal Endometriotic Cyst: A Case Report

    Full Text Available A seventy-three-year-old patient%u2019s vaginal examination revealed a semi-mobile cystic structure visualised at the middle third portion of the posterior vaginal wall. The cyst was excised and the cyst wall was sent for pathological examination. The histopathological examination of the cyst with CD10 staining and tests for nuclear estrogen receptor positivity and nuclear progesteron receptor positivity revealed that the cyst wall contained endometrial stromal cells, endometrial surface epithelial cells, and hemosiderin-laden macrophages. Endometriosis externa was diagnosed based on the above findings. The case we report here, of an isolated vaginal endometriotic cyst, is unique because of its presentation in a postmenopausal woman without any history of infertility, any gynecologic surgery, or hormone replacement therapy. The reasonable explanation for this case might include certain mechanisms such as the self-sustaining existence of endometriotic cells that were implanted during the premenopausal period to the vagina and that maintain local estrogen production. No single hypothesis can explain the pathophysiology of endometriosis, given all of its various forms and presentations.

    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

    Full Text Available The purpose of this study is to describe transient macular cysts in an infant and correlate their occurrence with normal development events. A newborn Caucasian girl presented with a protruding corneal mass in her left eye at birth. She underwent a complete ophthalmic examination. A keratinized staphylomatous malformation involving the entire cornea and precluding further visualization of the anterior and posterior segment was observed in the left eye. Spectral domain optical coherence tomography (SD-OCT of the right eye performed when the child was approximately 6-week-old had revealed an unexpected finding of macular cysts involving the inner nuclear and outer retinal layers. Corneal transplant in the left eye was performed a month later. Ocular examination under anesthesia just prior to surgery revealed normal intraocular pressure, anterior segment and retina in the right eye. SD-OCT was normal in both eyes and showed complete resolution of the cysts in the right eye. The patient had not been on any medications at that time. Although clinical retinal examination might be unremarkable, SD-OCT may reveal cystic spaces in the macula. In the absence of conditions known to be associated with macular edema, transient macular cysts may arise due to a developmental incompetence of the blood-retinal barrier or may represent transient spaces created during normal migration of retinal cells. Further study is warranted to delineate the entity of transient macular cysts in infancy.

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

    Full Text Available Hydatid cyst disease of lungs may not be symptomatic. It may present as spontaneous rupture in pleura or a bronchus. During spontaneous breathing, cyst content of endobronchially ruptured pulmonary hydatid cyst is mostly evacuated by coughing. However, during positive pressure ventilation such extruded fragments may lodge into smaller airway leading to an airway catastrophe. We present such accidental endobronchial rupture of pulmonary hydatid cyst during surgery, its prompt detection, and management by rigid bronchoscopy.

    Baker's cysts are fluid distensions of the gastrocnemius-semimembranosus bursa and are the most common cystic lesion around the knee. Typically cysts enlarge along intermuscular planes around the knee. We report three cases in which the expanding cyst did not respect these planes and dissected along an intramuscular route as confirmed by MR imaging. Such behaviour by Baker's cysts is hitherto unreported in the literature. Possible mechanisms to account for this phenomenon are discussed. (orig.)

  11. Development of the yellow potato cyst nematode Globodera rostochiensis (Woll.) on potatoes after gamma irradiation of cysts

    International Nuclear Information System (INIS)

    Gamma irradiation inhibited the development of the yellow potato cyst nematode, Globodera rostochiensis (Woll.) Behrens when cysts containing juveniles in anabiosis were irradiated with a dose of 0.5 kGy or higher. A dose of 0.5 kGy reduced the infestation level and the density of females/cysts on root of infested plants. However, a few cysts were found on roots of plants grown in pots with soil treated with a dose of 3.0 kGy. Development of the second generation of the potato cyst nematode (= F1 cysts that originated from irradiated cysts) was much weaker than that of the parental generation. The F1 females and/or cysts were found only in the control and in the 0.5 kGy treatment in low numbers. (author)

They communicate with the nucleus pulposus of the intervertebral disc and cause symptoms by radicular compression. We report a unique case of lumbar disc cyst that was associated with disc herniation and contralateral radiculopathy. A 22 year old male presented with one month history of back-ache radiating to the left leg. Magnetic Resonance Imaging (MRI showed L3-L4 disc herniation with annular tear and cystic lesion in the extradural space anterior to the thecal sac on right side, which increased in size over a period of 3 weeks. L3 laminectomy and bilateral discectomy and cyst excision was done with partial improvement of patients symptoms.

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

    Ultrasonographic characteristics of two common musculoskeletal lesions, ganglion cysts (GCs) and synovial cysts (SCs) are presented through a review of the literature. Although similar in many ways, these two lesions display different morphostructural characteristics justifying, in our view, their descriptions as separate entities. Mainly different from an anatomopathologic point of view, they also differ in their potential therapeutic implications. A symptomatic GC, refractory to conservative therapy, may require surgical excision of the cyst itself. For SC, therapy should primarily be oriented toward identifying and correcting the often coexisting intra-articular disease instead of only targeting merely its consequence, the SC. PMID:25190552

    Hydatid disease is a parasitic infection that is remains endemic in many countries, particularly the Middle East and Central Asia. Mediastinal hydatidosis is very rare (less than 0.1% of all hydatid disease cases) that have been only anecdotally in the literature. To the best of our knowledge only one case of multiple mediastineal hydatid cysts has been reported previously. We report the second cases of multiple mediastineal hydatid cysts and recommend that it can be considered in the differential diagnosis of multiple cystic mediastineal masses in endemic countries.

    Pilonidal sinus is a long-standing chronic inflammatory condition consisting of a sinus tract from the skin-lined orifice extending into subcutaneous tissue, with hairs attached to the wall of the tract and projecting outside of the opening. Penile location is rare, and differential diagnosis with severe balanoposthitis, epidermal cysts, and neoplasms can be difficult. We report a rare case of pilonidal cyst located between coronal sulcus and prepuce which, due to its ulcerated aspect and absence of a tract with projecting hairs, simulated a penile carcinoma.

A key to the success of T. gondii as a parasite 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. Because most of the antibodies and reagents that recognize the cyst wall recognize carbohydrates, identification of the components of the cyst wall has been technically challenging. 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 reduced cyst number and a fragile brain cyst phenotype characterized 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 confers essential sturdiness to the T. gondii tissue cyst critical for persistence of bradyzoite forms. PMID:24385904

    Ibne Karim M Ali

    Full Text Available 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.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.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.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.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.

  8. A Case Report on the Choledochal Cyst in Pregnancy

    2014-12-01

    Full Text Available Introduction: Choledochal cyst is a rare congenital abnormality of the biliary tract presented primarily in infants and young children. It is very uncommon for choledochal cyst to be demonstrated during pregnancy. In fact, its manifestations during pregnancy are nonspecific and variable. If symptoms of abdominal pain, and jaundice were observed, choledocal cyst should be considered as a differential diagnosis. MRI is regarded more reliable in order to diagnose the number and anatomic location of the cyst. Magnetic resonance cholangiopancratogeraphy is another diagnostic method which can be opted for in pregnancy. Moreover, Laprascopy can be utilized for the cyst fenestration treatment.

  9. Identification of an intraspinal arachnoidal cyst by CT

    International Nuclear Information System (INIS)

    Clarification of the subjective complaints caused by meningeal malformations represented by an arachnoidal cyst in the sacral region was achieved for the first time by analysing an arachnoidal cyst which had been determined by myelography, computed tomography, biopsy and histological examination. Principles of mechanics and dynamics play an important part. The pattern of complaints is mainly due to the communication between the cyst and the CSF space, as well as a valve mechanism with filling of the cyst. Surgical reduction or removal of the cyst, and elimination of the connection with the CSF, produced freedom from complaints. (orig.)

    International Nuclear Information System (INIS)

    The most common cause of echinococcosis in humans is Echinococcus granulosus. Although hydatid cyst is most frequently localized in liver (more than 65% of cases) and lung (25%) by means of portal and systemic circulation, it may involve other tissues and organs. Cardiac hydatid cysts account for only 0.5%-2% of all hydatid cysts, even in endemic areas. Of all cardiac hydatid cysts, the left ventricle accounts for 60%, right ventricle 10%, pericardium 7%, pulmonary artery 6%, left atrial appendage 6%, and interventricular septum 4%. We report the case of a myocardial hydatid cyst of the left ventricle in a 9-year-old boy. (author)

  11. Epidermoid Cyst of the Testicle: Unusual Magnetic Resonance Imaging Findings

    International Nuclear Information System (INIS)

    Epidermoid cyst of the testis is an uncommon benign tumor that can be treated by organ-preserving surgery when diagnosed preoperatively. Although some sonographic characteristics may be suggestive of epidermoid cysts, sonography is not completely diagnostic. Magnetic resonance imaging (MRI) findings may provide support for the diagnosis of epidermoid cysts. The MRI findings of testicular epidermoid cysts have been reported as either bull's eye or target in appearance, or with signal intensity characteristics more typical of a cystic lesion. In this paper, we present typical sonographic and unusual MRI findings of a testicular epidermoid cyst

    We present a case of suprasellar arachnoid cyst which was revealed by visual impairement and hypopituitarism. Neuroradiological imaging showed the peculiar association of the suprasellar cyst with cerebellar tonsillar herniation and a large asymptomatic cervical syringomyelic cavity. Surgical treatment of the suprasellar cyst allowed the reduction of both the cyst and the syrinx. A common pathophysiological mechanism of these lesions is discussed. We suggest the possibility that an initial obstruction of the basal cisterns caused the suprasellar cyst formation which led to medullar cavity formation. PMID:10790641

    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

    Epidermal cyst within a toe phalanx is an extremely rare condition. It is important to differentiate this benign lesion, which can be easily treated by curettage, from other benign and malignant lesions of the bone with a similar clinical presentation, and which may require amputation of the toe. This report describes one such lesion in the mid-phalanx of the fourth toe in a 48-year-old woman, and which was successfully identified by intra-operative frozen diagnosis and treated by curettage.

    Retrorectal, developmental tail gut cysts, include dermoid cysts, rectal duplication cysts and retrorectal cyst-hama-rtomas. Retrorectal cyst-hamartomas (RCH) are derived from remnants of the tail gut, the most caudal part of the embryonic hind gut, which normally involutes by the 8th wk of embryonic development (3-8 mm stage). They have specific radiological and histopathological features that distinguish them from other similar formations (dermoid cysts, enteric duplication cysts and terato...

    Dermoid cysts are malformations that rarely seen in oral mucosa and can be defined as an epidermoid when lining presents only epithelium. Epidermoid and dermoid cysts are rarely seen in intraosseous and there was a few report about their presentation in the jaws. The development in implant surfaces and surgical techniques has led to changes in treatment protocol such as immediate implant placement. Immediate implant placement has some advantages such as, reduction in the time of treatment and...

    A 31-year-old man presented with a recurrent abscess in the gluteal cleft. It was interpreted as a pilonidal sinus and he underwent surgery several times. The modified Bascom's asymmetric midgluteal cleft closure technique was used without satisfying clinical remission. Endoscopy, magnetic resonance imaging and transrectal ultrasound visualized a pre-sacral cyst, which was excised in toto with laterosacral approach of Kraske. A histological examination showed epidermal inclusion cyst. The post-operative course was uneventful. PMID:25612946

    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

  20. Diagnostic value of magnetic resonance imaging in postoperative maxillary cyst

    International Nuclear Information System (INIS)

    Magnetic resonance imaging (MRI) is superior to conventional X-ray tomography and CT scanning in detecting postoperative maxillary cysts (POMCs). We analyzed the MRI features of 51 cases (72 sides) and compared them with the operative findings of 42 cases (52 sides) of POMC. The total number of cysts diagnosed was 121. Multiple cysts were found in 37 sides (51%) and bilateral cysts were found in 21 cases (45%). According to classification of POMC based on location in the maxilla, the central cysts were found in only 38% of all cysts (peripheral ones in 62%). In the 42 patients operated on, 69 of 83 cysts which had been detected by MRI were confirmed, whereas there were two additional cysts which could not be diagnosed preoperatively. Sixty-four of 71 cysts were opened to the nasal cavity under endonasal endoscopic control. The other seven cysts (five sides) were operated on via a buccogingival incision. Detailed and accurate diagnosis by MRI and development of endoscopic instruments enabled endonasal surgery in most (91%) sides of the POMC. In five cysts of the superior type which are small, isolated and distant from the lateral wall of the nasal cavity, endoscopic endonasal surgery was not indicated. In conclusion, MRI for POMC was extremely helpful in selecting a surgical approach. (author)
