    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.

    Full Text Available Solitary bone cysts, also known as unicameral bone cysts or simple bone cysts, are benign tumors of the bone full of liquid. While typically seen on proximal humerus and femur bones, they are rarely seen on other bones. Simple bone cysts, diagnosed with X-ray. incidentally or for other reasons, are usually asymptomatic. In this case, a 25-year-old male patient with pathologic fracture of the proximal phalanx from an undiagnosed simple bone cyst was reported and referred to the authors' clinic to be treated with curettage.

Chondroblastoma of the calcaneum is uncommon and its association with secondary aneurysmal bone cyst is even rarer. Only two cases of calcaneal chondroblastoma associated with secondary aneurysmal bone cyst have been reported till date. A 22-year-old male presented to the department of orthopaedics with complains of pain and swelling in the left heel since the last 10 months. On clinico-radiological grounds differentials considered were giant cell tumour of bone and aneurysmal bone cyst. In view of the histopathological findings of bone curettage and results of special stain and immunohistochemical marker, final diagnosis of chondroblastoma with secondary aneurysmal bone cyst, left calcaneum was rendered. Although rare, chondroblastoma should always be considered in osteolytic lesions of calcaneum. The identification of secondary aneurysmal bone cyst component is important as it has higher chances of recurrence than usual chondroblastoma. PMID:27504302

  10. 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.

  11. 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

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

    We report on a 69-year-old woman with a solid variant of aneurysmal bone cyst (solid ABC) in the left humerus with a pathological fracture. Radiographically, the lesion exhibited a relatively well-defined osteolytic lesion in the diaphysis of the left humerus. On magnetic resonance (MR) imaging, the medullary lesion exhibited a homogeneous signal intensity isointense with surrounding normal muscles on the T1-weighted images and a mixture of low and high signal intensity on the T2-weighted images. Contrast-enhanced T1-weighted images revealed diffuse enhancement of the entire lesion. The pathological study showed a proliferation of fibroblasts, histiocytes, chronic inflammatory cells and numerous multinucleated giant cells in a collagenous matrix. Abundant osteoid formation in the matrix was observed, but the cells were devoid of nuclear atypia. Aneurysmal cystic cavities were absent. A review of the English literature found 22 cases of solid ABC of the long bones. (orig.)

    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.

    2006-09-01

    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 .

    2016-01-01

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

    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.

  6. Intracystic negative pressure may promote bone formation around jaw cysts

    Institute of Scientific and Technical Information of China (English)

    ZHAO Yi; HAN Qi-bing; LIU Bing

    2011-01-01

    The growth and enlargement of jaw cysts are associated with raised intracystic pressure and bone resorption surrounding the cysts. The major bone-resorbing cells are the osteoclasts. They are acting under the influence of local bone-resorbing factors: prostaglandins, proteinases and cytokines. It was found that positive pressure enhanced the expression of IL-1αmRNA and protein in epithelial cells of odontogenic keratocyst, and increased the secretion of matrix metalloproteinase and PGE in a co-culture of odontogenic keratocyst fibroblasts and epithelial cells. However, the signal intensities for IL-1α mRNA and protein in the epithelium were significantly decreased after marsupialization which relived intracystic pressure. Experimental study indicated that intermittent negative pressure could promote osteogenesis in human bone marrow-derived stroma cells (BMSCs) in vitro. We propose a hypothesis that bone formation around the cyst of the jaws would be stimulated by intracystic negative pressure.

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

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

    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.

    @@ An aneurysmal bone cyst is a non-neoplastic, Adestructive and expansile lesion consisting of a "blood-filled sponge" that is defined to represent a benign reactive vascularity.1-3 Szendroi et al4 suggested that the aneurysmal bone cyst corresponds to a haemodynamic disturbance that is primary or secondary venous malformation of the bones. The association with trauma including fracture has also been noted and 25%-71% of such patients have a history of trauma.57 Conventionally, malignant transformation of aneurysmal bone cysts is perceived as a rare occurrence except those induced by irradiation.8-10~ Both malignant fibrous histiocytoma and osteosarcoma have been reported in the malignant transformation cases.

    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.

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

    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.

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

    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

    Full Text Available The results of the study of diagnostically important metabolism parameters in patients with bone cysts in different stages of the disease are presented. It is shown that an increase activity of protein banding collagenase, alkaline phosphatase and also of hydroxyproline, glycosaminoglycans contents due to lower levels of calcium and inorganic phosphate levels increase in blood serum are expressed in a stage osteolysis than the step of separating. Decreasing the amount of glycosaminoglycans and collagen in bone indicates an intensification of catabolic processes in the connective tissue matrix. Diagnostically important indicators of the degree of disturbance of bone metabolism are the level of collagen, proteoglycans and activity of marker enzymes — collagenase and alkaline phosphatase. Based on the evaluation of sensitivity, specificity and diagnostic efficiency of the obtained results, we can recommend the threshold values of the investigated parameters of basic organic components and mineral metabolism of bone for the differential diagnosis of stages of bone cysts in children, which will serve as a basis for the development of appropriate diagnostic tests.

    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

    2001-06-01

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

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

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

Case An 11-year-old female presented with a swelling over her right iliac region and numbness along the medial aspect of thigh. Clinicoradiological diagnosis was aneurysmal bone cyst confirmed on fine needle aspiration cytology. Excision curettage (wide margin excision of the soft tissue tumor and intralesional curettage in the region of acetabulum of the tumor was performed in view of proximity to acetabular roof and endangered hip stability. Result At follow up of 18 months, the child has full painless range of movements in the hip joint with no recurrence. Conclusions Pelvic aneurysmal bone cysts are distinctly rare in pediatric age. The lesion was associated with an atypical symptom of numbness along the femoral nerve distribution. Hip stability and range of movements were major concern in this patient. Although many treatment options are described, surgical excision still remains the mainstay. In our case, we performed excision curettage, with good outcome.

    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.

    Aneurysmal bone cyst (ABC) arising in the petrous portion of the temporal bone is a rare entity with only five such reported cases in the literature. We report the case of a 28-year-old man who presented with a tender swelling in the right preauricular region with right ear discharge and conductive hearing loss of 4 years' duration. Computed tomography and Magnetic Resonance imaging showed a destructive lesion in the right petrous bone with cavitation consistent with the diagnosis of ABC. Gross total resection of the lesion was achieved and diagnosis was confirmed histologically. The patient had no recurrence at 12 months of follow-up. This report presents the unusual location of an uncommon bony tumor with a review of its clinical, radiological, and histopathological features as well as the treatment modalities available.

  1. Unicameral bone cyst of the lunate in an adult: case report

    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.

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

    Full Text Available Background: Simple bone cyst is a common benign lesion in the proximal humerus, especially in prepubertal children. Up to 75 percent of patients with the bone cyst have a pathologic fracture and the most significant complication is recurrent pathologic fracture. Since the process of spontaneous healing of these fractures is rare, treatment is required. Ideal treatment for simple bone cyst should stabilize pathologic fractures, assist healing and provide a quick return to normal activity with reduced complication and recurrence. Methods: In this descriptive case series study, 24 patients with simple bone cysts of the humerus were selected for retrograde flexible intramedullary nailing from the lateral cortex of the distal humerus, since 2000 to 2005 at Imam Khomeini Hospital, Tehran. The mean age of the patients was 14.4 years, ranging from 6-39 years. Results were evaluated by plain radiography using the classification system of Capanna et al. Results: The mean duration of follow up for 23 of the patients was 31 (9-51 months. One patient with short-term of follow-up was excluded. Of these patients, 91.3% were healed either completely (65.2% or with residual minor defect (26.1%. Only one cyst (4.3% persisted with no response to treatment and one patient (4.3% had a recurrence of the cyst. However, there was no instance of recurrent pathologic fracture among these patients. Conclusion: This study shows that flexible intramedullary nailing is an effective treatment for humeral simple bone cysts that reduces the chance of complication, recurrence of cyst or pathologic fracture. This technique provides sufficient stability for quick return to normal activity.

    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

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

    Full Text Available Abstract We report the case of a young adult who presented with a painful foot due to chondroblastoma associated with an aneurismal bone cyst. Chondroblastoma is a rare benign cartilaginous neoplasm that accounts for approximately 1% of all bone tumors and characteristically arises in the epiphysis of a long bone, particularly the humerus, tibia, and femur. Chondroblastoma can affect people of all ages. It is, however, most common in children and young adults between the ages of 10 and 20 years. Association of chondroblastoma with aneurysmal bone cyst is well documented however this association has only once been reported in the cuboid. Imaging techniques should be supplemented with an open biopsy for the final diagnosis. Management with curettage, use of high speed burr and bone grafting has shown very good outcomes.

    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.)

    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.)

  13. 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.)

    2015-01-01

    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.

    A 29-year-old woman complained of a 3-month history of left knee pain without trauma history. X-ray showed a well-defined osteolytic lesion with a sclerotic margin in the patella and magnetic resonance imaging showed T1-low and T2-high signal intensity with different fluid level. Our impression was an aneurysmal bone cyst. At surgery, the lesion was a blood-filled cystic cavity, surrounded by a gray or brownish tissue. Hemorrhagic soft tissues with recognizable bone fragments were observed. Curettage and autogenous bone graft was done. Microscopically, sheets of tumor cells were intermingled with some areas of eosinophilic chondroid matrix. The tumor cells showed oval-shaped nuclei with moderate eosinophilic cytoplasm. Several multinucleated giant cells and blood filled cystic cavities were observed. The final diagnosis was a chondroblastoma with a secondary aneurysmal bone cyst. At the post-operative 1.5-year follow-up, grafted bones were well incorporated radiographically and there were no recurrent evidence or any other abnormal symptoms. PMID:24639947

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

    Objective: Unicameral bone cyst is a nonneoplastic bone lesion characterized by its tenacity and risk of recurrence. Pathological fracture is common and is often the presenting symptom. The objective of the present study was to evaluate the results of hybrid external fixator for the treatment of a unicameral bone cyst with a pathological fracture. Methods: Hybrid external fixator for the treatment of a unicameral bone cyst was performed in twelve patients. These patients presented with a pathological fracture and were managed immediately with hybrid external fixator, of whom four had been managed conservatively at other clinics before they were referred to our department. The cyst was located in the proximal humerus in all patients. The mean age of the patients at the time of surgery was 8.7 years, and the mean duration of follow-up was 32.6 months. Radiographic evaluation was performed according to the criteria of Capanna et al., and the cyst was classified as completely healed, healed with residual radiolucency (osteolysis), recurred, or having no response. Results: The healing period ranged from three to eight months. Eight cysts healed completely, and three healed with residual radiolucent areas visible on radiographs. There was recurrence of one cyst that had healed with residual radiolucency. All of the cysts in the present study responded to treatment. A modulation of hybrid external fixator was necessary in three patients, as the bars had become too short after bone growth or the pins had been loose. No major complications were observed.Conclusion: Hybrid external fixator provides early stability, which allows early mobilization and thus obviates the need for a plaster cast. This method of treatment also allows for an early return to normal activity.

    Full Text Available Chondroblastoma with secondary aneurysmal bone cyst (ABC, especially in the anterior skull base, is an extremely rare condition. A 5-year-old boy presented with a large space-occupying lesion in the anterior skull base along with a left sided-epistaxis, proptosis and decreased vision. Radical excision of the lesion was performed by an endoscopic transnasal and transethmoidal approach. The patient recovered without any recurrence during a follow-up period of up to 28 months. Here, we review this rare case and discuss the clinical presentation and surgical treatment.

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

    Chondroblastoma is a benign bone tumor that typically arises in the epiphysis of a long bone. However, when it occurs in non-epiphyseal location in flat bones, it may create a diagnostic problem. We describe such a case of chondroblastoma arising in the iliac bone. A 29-year-old man was incidentally found to have a bony pelvic lesion while undergoing evaluation for Crohn's disease. The radiographs and CT revealed an expansile lytic lesion in the right iliac bone. A core biopsy of the lesion was performed. The histopathology revealed the lesion to be a chondroblastoma with secondary features of aneurysmal bone cyst. An en bloc surgical resection of the tumor was performed. (orig.)

    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

    Radicular cyst is one of the most commonly occurring cyst in the oral cavity it is usually preceded by trauma or an infectious condition which is followed by enlargement. In recent times there are several treatment procedures that are being applied in order to improve the postoperative condition and to accelerate the process of healing and regeneration in the affected site. A 22-year-old patient reported to our OPD with the chief complaint of swelling on the left side of the face since 2-3 months, on investigating it was diagnosed as Radicular cyst which was initially treated by endodontic treatment of the involved tooth followed by enucleation of the cyst further an apicoectomy was done. Finally a PRF and iliac crest graft was placed for aesthetic rehabilitation with 21. PMID:26266233

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

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

    The 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

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.

    Full Text Available INTRODUÇÃO: o cisto ósseo simples (cisto ósseo traumático, cisto ósseo hemorrágico, cisto ósseo solitário é uma lesão não-neoplásica que representa aproximadamente 1% de todos os cistos maxilares, acometendo as regiões de corpo e sínfise de mandíbula com maior freqüência. Trata-se de uma cavidade intra-óssea delimitada por fina camada de tecido conjuntivo frouxo, sem revestimento epitelial. É uma lesão assintomática comumente identificada em exames radiográficos de rotina, apresentando imagem radiolúcida unilocular bem definida. Sua etiopatogênese não está bem esclarecida, mas acredita-se que o trauma local seja um fator relacionado ao seu desenvolvimento. OBJETIVO: este trabalho relata dois casos de cisto ósseo simples descobertos em exames radiográficos de rotina de pacientes que estavam sob tratamento ortodôntico. RELATO DOS CASOS E DISCUSSÃO: em ambos os casos a hipótese diagnóstica foi confirmada através de biópsia incisional e exame histopatológico. O tratamento escolhido foi a curetagem óssea, radiografias panorâmicas de controle pós-operatório mostraram reparo ósseo no local. Nestes casos, discute-se se há relação do trauma associado ao tratamento ortodôntico com o surgimento do cisto ósseo simples, ou se representa apenas um achado radiográfico, que é mais freqüente nestes pacientes devido ao maior controle radiográfico a que são submetidos.INTRODUCTION: simple bone cyst (traumatic bone cyst, hemorrhagic bone cyst, solitary bone cyst is a non-neoplastic lesion which represents about 1% of all maxillary cysts, found mainly in mandibular body and symphysis. It is an intraosseous cavity covered by thin, loose fibrous connective tissue, without epithelial lining. Simple bone cysts are asymptomatic and are commonly found in routine radiographic examination as a well defined unilocular radiolucent lesion. Its etiopathogenesis remains obscure, but the local trauma is frequently related to its

    Full Text Available Aneurysmal bone cysts (ABCs are relatively rare but well-described expansile, osteolytic psuedocysts are most commonly seen in the long bones, pelvis, and vertebra. Although a well-described lesion, much confusion exists in its pathogenesis especially of the associations of this lesion with other lesions. Approximately, one-third of patients with ABC present simultaneously with another bone pathology. The aim of this paper is to describe a rare case of simultaneously occurring ABC of the maxilla and mandible with the mandibular lesion occurring predominantly as a giant cell granuloma. The paper discusses the various histopathological variations of ABC as well as different lesions associated with ABC and tries to provide a review of different pathogenesis theories of this interesting lesion.

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

    Full Text Available Abstract Background Choice of appropriate MR pulse sequence is important for any research studies using imaging-derived data. The aim of this study was to compare semiquantitative assessment of subchondral bone marrow edema-like lesions and subchondral cysts using intermediate-weighted (IW fat-suppressed (fs spin echo and Dual Echo Steady State (DESS sequences on 3 T MRI. Methods Included were 201 subjects aged 35-65 with frequent knee pain. 3T MRI was performed with the same sequence protocol as in the Osteoarthritis Initiative (OAI. In a primary reading subchondral bone marrow edema-like lesions were assessed according to the WORMS system. Two hundred subregions with such lesions were randomly chosen. The extent of subchondral bone marrow edema-like lesions was re-evaluated separately using sagittal IW fs and DESS sequences according to WORMS. Lesion size and confidence of the differentiation between subchondral bone marrow edema-like lesions and subchondral cysts located within or adjacent to them was rated from 0 to 3. Wilcoxon signed-rank tests and chi-square statistics were used to examine differences between the two sequences. Results Of 200 subchondral bone marrow edema-like lesions detected by IW fs sequence, 93 lesions (46.5% were not depicted by the DESS sequence. The IW fs sequence depicted subchondral bone marrow edema-like lesions to a larger extent than DESS (p Conclusions In direct comparison the IW fs sequence depicts more subchondral bone marrow edema-like lesions and better demonstrate the extent of their maximum size. The DESS sequence helps in the differentiation of subchondral bone marrow edema-like lesions and subchondral cysts. The IW fs sequence should be used for determination of lesion extent whenever the size of subchondral bone marrow edema-like lesions is the focus of attention.

    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

    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.

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

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

    Background Echinococcosis is still endemic in many countries, including China, where it is especially prevalent in the northwest. The aim of this study was to enrich the international literature about the treatment of intracranial hydatid cysts.Methods We retrospectively reviewed the clinical features, radiological manifestations, and surgical outcome of 97 patients with intracranial hydatid cysts, who received surgical treatment at the Neurosurgical Department of First Affiliated Hospital of Xinjiang Medical University from 1985 to 2010 and followed up the patient via sending a questionnaire or telephone contact. Clinical outcome was evaluated using the Karnofsky Performance Scale Index.Results Headache and vomiting were the most common initial symptoms in our patients. Neurological deficits caused by the mass effect of the cysts were seen in 82 cases. On the X-ray, significant bone erosion was seen in only two cases with epidural hydatid cysts. Round-shaped and thin-walled homogeneous low-density cystic lesions without surrounding edema and enhancement were the main findings on computerized tomography (CT) in 95 patients with intraparenchymal hydatid cysts, while two cases with epidural hydatid cysts presented as a heterodensity lesions. On magnetic resonance imaging (MRI), hydatid cyst presented as a round-shaped low signal lesion in T1-weighted images and high signal lesion in T2-weighted images, without enhancement after contrast media injection, while the two cases with epidural cysts presented as mixed signal masses. Surgical removal of cyst was performed in all cases. Total removal was achieved in 93 cases without rupturing the cyst wall. Only two cysts ruptured during the dissection, resulting in two surgery-related mortalities. There was no other additional neurological deficit caused directly by surgery. In 97.2% of the patients, the Karnofsky Performance Scale score was 80 to 90 at the last follow-up.Conclusions Intracranial hydatid cyst is still a

A bewildering variety of developmental, odontogenic and non-odontogenic cysts are seen. Epidermoid cyst is a rare developmental cyst of the oro-facial region which results from entrapped epidermal elements without adnexal appendages. Dermoid and epidermoid cysts occur in oro-facial region with an incidence of 6.9-7% and represents less than 0.01% of all oral cavity cysts. Here we report two cases of epidermoid cysts occurring at unusual locations involving upper left maxillary region lateral to the nose and pinna of the ear.

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

    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.

  16. Amoxicillin concentrations in serum, jaw cyst, and jawbone following a single oral administration.

    Akimoto, Y; Kaneko, K; Tamura, T

    1982-05-01

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

    Objective To discuss the diagnosis, differential diagnosis and therapeutics of the juxtaarticular bone cyst in the acetabulum. Methods Between August 1990 to April 2009, nineteen cases of clinical data of the juxta-articular bone cyst in the acetabulum data were collected from hospital records and analyzed retrospectively. There were 11 males and 8 females, with an average age of 42.3 years (range, 18-59). Seventeen patients felt an aching pain in the hip. The duration of symptoms was from 2 months to 20years with the median 15 months. All the radiographs showed a well-demarcated oval or circular radiolucent defect, close to subchondral bone, and outlined by a thin rim of sclerotic bone. Five cases accompanied with developmental dysplasia of the hip. After curettage of the bone cyst, 14 patients received iliac crest autogenous bone grafts, 3 patients received xenoma spongy bone-graft particles, and 2 patients received artificial bone grafts. Results Fourteen patients were precisely diagnosed as bone cyst by radiograph, and 4 patients were diagnosed by CT and MRI. The major axes of the focus were 2-4 cm in 16 patients, and 4-8 cm in 3patients. The sizes of the focus had no relationship with the symptoms and the course of the disease. Seventeen cases of the focus were located at the anterior superior of the bearing surface of the acetabulum. All patients were successfully followed up from 11 months to 13 years, averaged 6.2 years, and no relapses occurred during the follow-up period in every case. Fourteen patients felt asymptomatic, 3 patients felt uncomfortable in hip occasionally, and 2 patients with developmental dysplasia of the hip felt ameliorated in the initial stage of the therapy, followed by aggravation accompanying the hip joint space narrow. Conclusion Bone graft after thorough curettage of the capsular space was an effective therapy for the juxta-articular bone cyst in the acetabulum, and the anatomic distribution of radiological lesions indicated that

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.

    The purpose of this study was to review and re-evaluate the well-known ultrasonographic characteristics of cysts of the thyroglossal duct. 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.

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

    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.

    Objective To analyze the clinical features, imaging characteristics, differential diagnosis, clinical treatment methods and recurrence rate of aneurysmal bone cysts of the metacarpals and phalanges of the hand. Methods The clinical data of 12 patients with aneurysmal bone cysts of the metacarpals and phalanges of the hand who were adopted from 2002 to 2012 were retrospectively analyzed, including the clinical symptoms and signs, X-ray and Magnetic Resonance Imaging ( MRI ) features, intraoperative general characteristics, tumor performance, operative methods, bone graft and postoperative recurrence rate. Results Among the 12 cases, there were 8 cases in the metacarpal and 4 cases in the phalange. No deifnite characteristics existed referring to the age or gender. Local inlfation in 8 cases and pain in 6 cases were the main clinical features. The X-ray showed expansive lytic lesion, and soap-bubble-like and balloon-like bone destruction was noticed in the advanced stage. The MRI showed cyst cavities of various sizes and different signal intensities and intralesional lfuid-lfuid level. During the operation, the bone cortex became purple and thin and swelled. Curettage and bone grafting by a high-speed drill were performed on 4 patients, and resection and reconstruction on 8 patients. Postoperative recurrence was found in 1 case. The deifnitive diagnosis was made by the histopathological examination in all the patients. Combined giant cell tumors were noticed in 1 case. Conclusions Aneurysmal bone cysts of the metacarpals and phalanges of the hand is an infrequent disease, without speciifc clinical manifestations. It is very dififcult to make an early diagnosis, and it should be differentiated from other hand bone tumors. Based on the history characteristics and the X-ray and MRI examinations, the correct diagnosis ratio can be distinctly improved. The recurrence rate can be greatly reduced under the treatment of thorough curettage by a high-speed drill and resection

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

    2012-01-01

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

    BACKGROUND: The treatment of an ovarian cyst relies on its nature, and accurate preoperative discrimination of benign and malignant cysts is therefore of crucial importance. This study was undertaken to review the literature concerning the preoperative diagnosis and treatment of ovarian cysts....... METHODS: Articles concerning ovarian cysts from a medline literature search during the period 1985-2003 were included in addition to articles found as references in the initial publications. RESULTS: Different methods for discriminating between benign and malignant ovarian cysts are discussed....... The diagnosis and the treatment are assessed in relation to age, menopausal status, pregnancy, and whether the cyst is presumed to be benign or malignant. In general, expectant management is the choice in premenopausal and pregnant women with non-suspicious cysts and normal levels of CA-125. In postmenopausal...

    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.

    Full Text Available : Hydatid cyst caused by the larval stage of the parasite Echinococcus is manifested by slowly growing cystic mass. E. Granulosus accounts for the majority of the cases whilst E. Multilocularis and E. Vogeli are rare. Human happen to be accidental or incidental intermediate host and, as far as the parasite is concerned, a dead end. Liver is the most common organ involved and, together with the lung accounts for 90% of cases. The 10% cases that do not involve the liver and lung usually affect muscle, peritoneum, bone, spleen, pancreas, heart, kidney and brain instead. Here we describe a case of hydatid cyst of peritoneum

    To evaluate the usefulness of a dental CT software program in the assessment of jaw cysts and in the differentiation of odontogenic keratocysts and other cysts. Seventeen patients with proven jaw cysts(8 maxillae and 9 mandibles) were evaluated with a dental CT sofware program for location, locularity, the presence or absence of marginal scallping, and height to length ratio. For the delineation of involvement or displace-ment of neurovascular bundles, cortical erosion, perforation or expansion, and tooth root resorption by the jaw cysts, images from this program were compared to conventional images. Seventeen lesions icomprised 15 odontogenic cysts (five odontogenic keratocysts, five radicular, three residual and two dentigerous cysts) and two non-odontogenic cysts (one nasopalatine duct cyst and one postoperative maxillary cyst). Images of jaw cysts obtained with the dental CT software program delineated much more clearly than conventional images the status of neurovascular bundle and cortical bone, but there was no clear difference between the two modalities in delineating tooth root erosion. Dental CT findings of five mandibular odontogenic keratocysts were scalloped margin in all, mandibular ramus involvement in four, height to length ratio below 60% in four ,and multilocularity in two. The findings of the other 12 cysts (eight maxillae and four mandibles) were unilocularity in all, smooth inner margin in ten, height to length ratio below 60% in only two, and ramus involvement in none. A dental CT software program is an improved imaging modality for assessing jaw cysts;and findings which tend to indicate odontogenic keratocysts are marginal scalloping, mandibular ramus involvement, prominent spread along the marrow space and multilocularity.

    Full Text Available A cyst following implantation of respiratory epithelium during surgical procedures has been documented only rarely. A variety of names have been attached to this lesion: respiratory mucocele, respiratory implantation cyst, surgical ciliated cyst, and surgical (implantation cyst. In seven prior case reports, the interval between the initiating surgical procedure and diagnostic biopsy of the resultant well-circumscribed radiolucency and histopathological demonstration of distinctive pseudostratified ciliated columnar epithelial lining has varied from 4 to 40 years. In the case reported here, chin augmentation used "residual maxillary bone" as the donor tissue and likely transplanted sinonasal mucosa into the mandible during orthognathic surgery, resulting in a painful anterior mandibular cyst lined by respiratory epithelium that was ablated 16 years later.

    Full Text Available Eruption cyst is a benign cyst associated with a primary or permanent tooth in its soft tissue phase after erupting through the bone. It is most prevalent in the Caucasian race. Intraoral examination of four patients revealed eruption cyst. Among these, in three patients it occurred in the maxillary arch and one had it in the mandibular arch. All were associated with permanent tooth. Surgical treatment was done in three cases and in one case the cyst disappeared gradually and tooth erupted in normal pattern. Four cases of eruption cyst from India are presented and literature on this condition is reviewed. It is clinically significant in that knowledge among general dentists is very essential regarding this developmental disturbance to reach the correct diagnosis and to provide proper treatment.

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

    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.

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

  4. To Cut or not to Cut: Can Large Periapical Cysts be Treated by Endodontic Treatment only?

    Directory of Open Access Journals (Sweden)

    MHK Motamedi

    2010-05-01

    Full Text Available Introduction: The periapical cyst originates from the epithe-lium in a granuloma and is frequently associated with an inflammatory response to a necrotic pulp. This condition is clinically asymptomatic but can result in a slow-growth, bone resorption and swelling in the affected region.The hypothesis: Some authors support that if the endodontic infection is eliminated, the immune system is able to promote lesion repair, while others believe that surgical intervention is invariably nec-essary to remove cyst epithelium. This hypothesis indicates that large periapical cysts may be treated by only nonsurgical endodontic treatment.Evaluation of the hypothesis: Radicular cysts exist in two structurally distinct classes namely, those containing cavities completely enclosed in epithelial lining (periapical true cysts and those containing epithelium-lined cavities that are open to the root canals (periapical pocket cysts. From a clinical point of view a periapical pocket cyst may heal after conventional root canal therapy whereas an apical true cyst is less likely to be resolved without surgical intervention. During the endodontic therapy of teeth associated with periapi-cal cysts, root canal instrumentation could be done slightly beyond the apical foramen. This will produce a transitory acute inflammation and destruction of the protective epithelial layer of the cyst, converting it into a granulated tissue, which has better resolution. Instru-mentation beyond the apical foramen could be carried out because it would help in cyst resolution through the relief of the intra-cystic pressure.

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

    2016-03-01

    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.

    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.

    The purpose of this study was to determine the incidence of meniscal cysts, assess the frequency of various magnetic resonance (MR) imaging characteristics, and emphasize radiographic observations not commonly reported. A total of 2,095 consecutive knee MR imaging reports from a 22 month period were retrospectively reviewed for the presence of meniscal cysts. Two musculoskeletal radiologists reviewed the cases where cysts were reported. A meniscal cyst was considered present if abnormally increased signal was identified within an enlarged meniscus (i.e., intrameniscal cyst) or if a loculated fluid-intensity lesion with a clear connection to the adjacent meniscus was identified (i.e., parameniscal cyst). Presence or absence of a meniscal tear, intrameniscal and parameniscal signal intensity, patient age, sex, location of meniscal cyst, presence of discoid meniscus, and size of the parameniscal cyst component were recorded. All knee imaging examinations were performed on a 1.5T MR unit. Imaging findings were correlated with arthroscopic reports when available. A total of 167 cases (8.0%) of meniscal cysts were diagnosed in 161 patients. Of the 167 cysts, 69 (41.3%) were located in the lateral meniscus and 98 (58.7%) in the medial meniscus. In 6 patients (3.7%), meniscal cysts were present in both menisci of the same knee. Twelve (7.2%) meniscal cysts were associated with discoid menisci. Ninety-seven (57.8%) meniscal cysts were associated with meniscal tears. Of the total number of meniscal cysts, 104 (62.3%) had a parameniscal cyst. An isolated intrameniscal cyst was present in 63 (37.7%) cases. One hundred (96%) of the parameniscal cyst components were isointense to fluid on T2-weighted FSE images. All cysts exhibited abnormal intrameniscal signal. Only 14 (8.4%) of the intrameniscal components were isointense to fluid on T2-weighted FSE images. The arthroscopic reports of 88 of the 161 (54.7%) patients were available for review and correlation. A tear extending to

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

    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 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.

    Magnetic resonance imaging (MRI) features of 11 surgically resected pelvic tailgut cysts were analyzed with reference to histopathologic and clinical data. Homogeneity, size, location, signal intensity, appearance and presence of septa and/or nodules and/or peripheral rim and involvement of surrounding structures were studied. Histological examination demonstrated 11 tailgut cysts (TGC), including one infected TGC and one TGC with a component of adenocarcinoma. Lesions (3-8 cm in diameter) were exclusively or partly retrorectal in all cases but one, with an extension down the anal canal in five cases. Lesions were multicystic in all patients but one. On T1-weighted MR images, all cystic lesions contained at least one hyperintense cyst. The peripheral rim of the cystic lesion was regular and non or moderately enhancing in all cases but the two complicated TGC. Nodular peripheral rim and irregular septa were seen in the degenerated TGC. Marked enhancement of the peripheral structures was noted in the two complicated TGC. Pelvic MRI is a valuable tool in the preoperative evaluation of TGC. (orig.)

    Energy Technology Data Exchange (ETDEWEB)

    Ahuja, A.T.; King, A.D.; Metreweli, C

    2000-10-01

    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)

    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

    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.

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.

    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

    A 52 year-old construction worker presented with progressive painful blurring of vision in the left eye associated with redness for past 1 month. There was a history of penetrating injury in the same eye 10 years ago and he underwent primary wound toilet and suturing, lens removal with intraocular lens implantation. Slit lamp examination revealed a corneal scar at 9’oclock, a large transilluminant iris cyst superotemporally and adherent to corneal endothelium. It was extended from angle of the pupil and obstructing the visual axis. The patient underwent excision of an iris cyst through superior limbal incision. Viscodissection was done to separate the cyst from the corneal endothelium and underlying iris stroma. Trypan blue ophthalmic solution was injected into the cyst to stain the cyst capsule. Post operatively 7 days, vision improved to 6/7.5 without complication. There was no recurrence up to 1 year postoperation. Histopathological finding revealed a benign cyst mass lined by simple cuboidal to non-keratinized stratified squamous epithelium. We had achieved a good surgical outcome with no complication to date for our case study. We advocate this modified surgical method to completely remove iris cyst.

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

    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.

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.

  5. Ovarian cysts on prenatal MRI

    International Nuclear Information System (INIS)

    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.

    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

    2013-06-01

    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.

    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 Epidermoid cysts are benign slow growing more often extra-axial tumors that insinuate between brain structures, we present the clinical, imaging, and pathological findings in 35 years old female patients with atypical epidermoid cysts which was situated anterior, middle & posterior cranial fossa. NCCT head revealed hypodense lesion over right temporal and perisylvian region with extension in prepontine cistern with mass effect & midline shift and MRI findings revealed a non-enhancing heterogeneous signal intensity cystic lesion in right frontal & temporal region extending into prepontine cistern with restricted diffusion. Patient was detoriated in night of same day of admission, emergency Fronto-temporal craniotomy with anterior peterousectomy and subtotal resection was done. The histological examination confirms the epidermoid cyst. The timing of ectodermal tissue sequestration during fetal development may account for the occurrence of atypical epidermoid cysts.

  15. 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 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.

    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.

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

    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.

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

    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.

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

    The 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.

  7. 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.

    Full Text Available Introduction: Dermoid cysts are congenital tumors caused by entrapment of ectoderm during embryogenesis. The most common localization are the gonads and less than 10% are in the head and neck. They are slow growing and generally observed between the second and third decades of life, being unusual in chilhood. Description: We report a case of a 5 year old male with recurrent respiratory infections, mouth breathing and snoring with apneas and daytime sleepiness. On physical examination tonsillar hypertrophy and a 4 cm sublingual tumor are detected. As complementary tests are performed overnight polysomnography with AHI of 18.3 / h and ultrasonography, reported as cystic mass with multiple rounded echogenic structures inside. Results: The patient was diagnosed with severe OSA and tonsillectomy and intraorally enucleation of tumor (as diagnosis and treatment were performed; with histopathological diagnosis of dermoid cyst. In the postoperative control we check the resolution of respiratory events and snoring. Discussion: Dermoid cysts of the oral cavity (where sublingual localization is the most common represent only 0,01% of all cysts and 1,6% of all dermoid cysts. Usually present as slow-growing asymptomatic mass, even if they reach large size can compromise swallowing, speech or breathing and eventually cause, as in our case, a severe OSA. The surgical treatment allows to confirm the diagnosis an avoid the risk of infectious complications and eventual malignant transformation.

    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

    Between 1974 and 1993, 22 patients with bronchogenic cysts were operated on in our hospital; there were 14 men and 8 women, ranging in age from 11 to 62 years, The cyst locations were mediastinal in 13 (59.1%) and intrapulmonary in 9 (40.9%). There were symptoms (chest pain and recurrent bronehiolits) in 20 patients (91%). The preoperative complications included infection in the lung and in the cyst and dysphagia due to esophageal eornpression. Chest pain was the main symptom in mediastinal cyst and recurrent infection of lung in intrapulmonary cyst. Plain chest radiograms showed that a rousd shadow, occasional air-fluid levels, and peripheral calcification may be found in cysts. An operation is the best treatment for cysts. All cysts were completely excised. No postoperative complieations, late complica-tions, or recurrence developed in our patients.

    Hydatid cyst disease is a zoonotic disease caused by Echinococcus granulosus, E.multilocularis or E.Vogli. The most common primary site is liver (75%) followed by lungs (5-15%) and other organs constitute 10-20%. Peritoneal hydatid cysts are very rare especially primary peritoneal hydatid. Secondary peritoneal hydatid cysts are relatively common, which usually occurs due to rupture of primary hepatic hydatid cyst. We present a rare case of large primary peritoneal hydatid cyst misdiagnosed as torsion of ovarian cyst that underwent Laparotomy with cyst excision and postoperative Albendazole therapy.

    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

    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

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

    Objective. To evaluate the surgery in simple ovarian cysts.Methods. From Jan. 1994 to Dec. 1999, 221 women with simple ovarian cysts were admitted into ourhospital. The diameter of cysts was <5 cm in 76 cases, and was≥5 cm in 145 cases ultrasonically.One hundred and eighty-four patients underwent laparosocopy, and thirty-seven underwent laparotomy.Results. Histological findings showed no malignancy in this series. Simple cysts, paraovarian cystsand corpus luteum were found histologically in 90.8% of cases with cysts <5 cm, and 60% of those withcysts >7 cm respectively, their difference was significant (X2=-37.13, P<0.001). The simple cysts, paraovar-ian cysts and corpus luteum cysts were found in 81.5% of postmenopausal women and 84.0% of pre-menopausal women. Conclusion. Patients with cysts >7 cm are indicated for surgical procedures, while a period of fol-lowup is acceptable for patients with cysts <7 cm, and surgery is advisable if the cyst is persistent dur-ing followup. Postmenopausal women with cysts should have operations.

    2014-12-01

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

  5. Chronic hematic cyst of the temporomandibular joint

    International Nuclear Information System (INIS)

    Hematic cyst refers to accumulation of blood or blood breakdown products in a non epithelium-lined fibrous tissue capsule. Hepatic cyst is a term often used for deeply placed, incompletely resorbed hematoma hemorrhagic cyst, which may remain unchanged and unidentified for long periods of time. Trauma is the major causative factor, although it is often vague or totally uncalled by the patient. Chronic hematic cysts are uncommon lesions those can present diagnostic challenge. In this article we report a first case of a chronic hematic cyst of the temporomandibular joint TMJ. (author)

    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.

    Bone tumors and tumorlike lesions of the spine are rare entities and may harbour diagnostic problems. In this article we discuss the epidemiology, topographic aspects, clinical and radiologic features as well as the diagnostic management of vertebral bone tumors. Entities that should be more familiar to the radiologist (i.e. osteoid osteoma, osteoblastoma, hemangioma, giant cell tumor, chordoma, aneurysmal bone cyst) are considered in more detail. (orig.)

  8. 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

    We herein report the case of an idiopathic liver cystic mass which aggressively infiltrated the thoracoabdominal wall. A 74-year-old woman who had a huge cystic lesion in her right hepatic lobe was transferred to our hospital for further examinations. Imaging studies revealed a simple liver cyst, and the cytological findings of intracystic fluid were negative. She was followed up periodically by computed tomography (CT) scans. Seven years later, she complained of a prominence and dull pain in her right thoraco-abdominal region. CT revealed an enlargement of the cystic lesion and infiltration into the intercostal subcutaneous tissue. We suspected the development of a malignancy inside the liver cyst such as cystadenocarcinoma, and she therefore underwent surgery. A tumor extirpation was performed, including the chest wall, from the 7th to the 10th rib, as well as a right hepatic lobectomy. Pathologically, the lesion consisted of severe inflammatory change with epithelioid cell granuloma and bone destruction without any malignant neoplasm. No specific pathogens were evident based on further histological and molecular examinations. Therefore the lesion was diagnosed to be a destructive granuloma associated with a long-standing hepatic cyst. Since undergoing surgery, the patient has been doing well without any signs of recurrence.

    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.

    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

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

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

    Full Text Available The most common symptoms of Mullerian cyst are abdominal discomfort and palpable abdominal mass. The diagnosis is based on the histological findings. Retroperitoneal Mullerian cysts should be completely excised. We report a case of a 41 years old woman treated for 2 retroperitoneal Mullerian cysts completely resected surgically. Retroperitoneal mullerian cyst is rare, the diagnosis is difficult preoperatively due to the lack of pathognomonic clinical and radiologic features. Its surgical excision is necessary to avoid recurrences. Mullerian cyst of the retroperitoneum is an extremely rare disease. Only 15 cases have been reported in the literature. They are characterized by the development of Mullerian epithelium-lined cysts in the retroperitoneum similar to the lining epithelium of the fallopian tubes and the endometrium.

    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.

    In all animals, germline cells differentiate in intimate contact with somatic cells and interactions between germline and soma are particularly important for germline development and function. In the male gonad of Drosophila melanogaster, the developing germline cells are enclosed by somatic cyst cells. The cyst cells are derived from cyst stem cells (CySCs) of somatic origin and codifferentiate with the germline cells. The fast generation cycle and the genetic tractability of Drosophila has ...

    Full Text Available Cystic lesions of the mediastinum may be congenital or acquired. The differential diagnosis depends on their location in the mediastinum. Cysts in the posterior mediastinum are generally developmental cysts and are neurogenic or of foregut origin. We report the case of a 14-year-old boy, who presented with dry cough and progressively increasing breathlessness, and was found to have a cystic lesion in the posterior mediastinum. Fine needle aspiration from the cyst helped make a diagnosis of tuberculosis.

    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.

    2011-01-01

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

  17. Concomitant pituitary adenoma and Rathke's cleft cyst

    International Nuclear Information System (INIS)

    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.)

    2007-09-01

    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.

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

    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...

    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.

    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.

    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.

    Full Text Available Abstract Hydatid disease, a parasitic infection is caused by Echinococcus granulosus. It has serious impact on health and economy especially in countries where it is endemic. It occurs frequently in liver and lung. The disease is chronic and cyst can localize in different organs. A hydatid cyst occurrence in the head and neck is extremely rare. To know the distribution of disease can help in its control and prevention. We report a case of primary cervical hydatid cyst in 20 year old female. A high index of suspicion is required to diagnose hydatid cyst in rare locations like this. Hydatid cyst should be considered in differential diagnosis of benign swellings of head and neck region, so that it can be managed during surgery to prevent acute anaphylaxis.

    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.

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

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

    The best surgical treatment of cerebral arachnoid cysts is yet to be established. Treatment options are shunting, endoscopic fenestration or microsurgical fenestration through craniotomy.Data from 69 patients with cerebral arachnoid cysts treated in our institution between 1997 and 2007 were...... reviewed.Cysts were located infratentorially in 20% (n = 14) and supratentorially in 80% (n = 55); of these 73% (n = 40) were in the middle cranial fossa. Mean cyst size was 61 mm (range 15-100 mm). The most common symptoms were headache (51%), dizziness (26%), cranial nerve dysfunction (23%), seizure (22......-up was 30 months. In the surgical series 79% (n = 45) had a good outcome.We conclude that the surgical treatment of arachnoid cysts has an overall good outcome. In our institution the best results were obtained with microsurgical decompression through craniotomy....

  7. Chylous mesenteric cysts: a rare surgical challenge.

    2014-03-01

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

    The purpose of this study was to evaluate the CT findings of thyroglossal duct cysts. Sixteen patients with pathologically proved thyroglossal duct cysts were included in the study. CT scans were assessed retrospectively for shape, size, location, density of the central portions, septations, rim enhancement, changes in the adjacent fascial planes and investment within the strap muscles in the infrahyoid cysts. Thirteen cases of thyroglossal duct cysts were seen as round or oval cystic masses, two cases of them were seen as irregular-shaped lobulated cystic masses, and one case was seen as ovoid soft tissue mass. The cysts were from 1.4 to 5.7 cm in diameter (mean, 2.6 cm). The cyst was infrahyoid in 15 cases and suprahyoid in one case. The cyst was located in midline in eight cases, off midline in four cases, and both midline and off midline in four cases. The density of the central portions ranged from 15 to 82HU (mean, 32HU). Septations were noted in four cases. Rim enhancement was seen in 14 cases (93%), and heterogeneously enhancing soft tissue mass was seen in one case. In four cases, abnormal fascial planes were observed. All but one of the infrahyoid cysts (14/15) were embedded within the strap muscles, and one case of them was located anteriorly to strap muscles. CT permits one to make the diagnosis a thyroglossal duct cyst with a high degree of accuracy, as it can differentiate thyroglossal duct cysts from the other anterior neck masses by their typical location, characteristic morphology, and investment within the strap muscles.

    This article reviews the role of CT and MR imaging in the diagnosis of benign bone tumors and tumor-like lesions of bone with with regard to differential diagnosis, the assessment of tumor-related complications, and the detection of postoperative recurrence. Indications for cross-sectional imaging of specific lesions, including osteoid osteoma, osteoblastoma, enchondroma, osteochondroma, intraosseous lipoma, hemangioma, giant cell tumor, aneurysmal bone cyst, simple bone cyst, and eosinophilic granuloma, are discussed, and advantages and disadvantages of the different imaging modalities are illustrated on the basis of pathologically confirmed cases.

    The authors evaluated six cases of surgically proven choledochal cysts diagnosed by real time ultrasonography. The results were as follows: 1. 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

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

    2015-01-01

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

    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.

    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.

    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.

    Full Text Available 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.

    2016-01-01

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

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

    The 'bone within a bone' appearance is a well-recognized radiological term with a variety of causes. It is important to recognize this appearance and also to be aware of the differential diagnosis. A number of common conditions infrequently cause this appearance. Other causes are rare and some remain primarily of historical interest, as they are no longer encountered in clinical practice. In this review we illustrate some of the conditions that can give the bone within a bone appearance and discuss the physiological and pathological aetiology of each where known.

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

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

    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.)

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

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

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

    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.

  11. Dermoid cyst in the mouth floor

    International Nuclear Information System (INIS)

    The Dermoid cyst account for the 0.01 % of all cysts of buccal cavity. Its more frequent location is in the mouth floor. This is the case of a female patient aged 19 who approximately 7 years noted an increase of volume under tongue growing gradually and noting outside face and the discomfort at to speak and to chew. Complementary studies were conducted and under general anesthesia a surgical exeresis was carried out by intrabuccal approach achieving excellent esthetic and functional results. Histopathologic diagnosis matched with a dermoid cyst of mouth floor. Patient has not lesion recurrence after three years after operation. We conclude that the Dermoid cyst of mouth floor appear as benign tumor of middle line. The intrabuccal exeresis demonstrates esthetic and functional benefits. (author)

    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

    Hydatic disease caused by Echinococcus granulosus is an endemic disease and an important public health problem in some countries of the world. The results of surgical treatment are associated with a high rate of mortality, morbidity, postoperative recurrence and a long period of hospital stay and the medical treatment results are still controversial. Although the percutaneous aspiration and treatment of liver hydatid cysts were considered to be contraindicated due to risks of anaphylactic shock and dissemination of clear-crystal fluid into the abdomen, several reports of successful percutaneous treatment of liver hydatid cysts have been published in the literature. Today, percutaneous treatment of liver hydatid cysts is the most effective and reliable treatment procedure in the selected cases. In this review, indications, contraindications, method and techniques, healing criteria, complications, results and importance of the percutaneous treatment of liver hydatid cysts are discussed.

    Full Text Available Abstract Introduction Retroperitoneal cysts are uncommon, with an estimated incidence of 1/5750 to 1/250,000. Case presentation A male patient was admitted with an abdominal pain, jaundice and fever. Clinical examination and investigations confirmed an idiopathic benign retroperitoneal cyst. He underwent surgery and was discharged after making good recovery. Conclusion Retroperitoneal cysts are very rare, and most of the time they are discovered incidentally. Patients may be asymptomatic or present with abdominal pain, referred pain to the legs or weight loss. Imaging may help diagnose these lesions, but surgery is the keystone in confirming the diagnosis. This case is very rare and very educational as it highlights an unusual presentation of a benign retroperitoneal cyst. In our patient, the course of the disease was unique as the patient presented with jaundice.

    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.

    Echinococcosis is a cyclozoonosis characterized by cystic lesions usually situated inside or outside the liver. We discuss the case of a 77-year-old woman with a recurrent hydatidosis with a cyst arising from the liver, growing through the lateral right abdomen wall, and reaching the subcutaneous tissue of the lumbar region. In the literature, rare subcutaneous or muscular localizations of hydatid cysts are described, however, there is no mention of a cyst growing over the abdominal wall muscles, shaped like an hourglass, partially in the liver and partially in the subcutaneous tissue, as in our case.We have not found any pathogenetic explanation for this growth pattern which is not typical of the biological behaviour of a hydatid cyst.

    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.

    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

    In a grid investigation, dinoflagellate cysts were collected from sediments in Xiamen Western Harbor in May of 2000,from which five species of cysts were identified: Alexandrium tamarensis, A. minutum, Lingulodinium polyedra,Gonyaulax scrippsae and Gymnodinium catenatum, account for about 21% in the species composition. The quantitative analysis of the sediments shows that the number of dinoflagellate cysts varies from 51 to 256 cysts/g of sediment, the highest value (>200 cysts/g) being recorded at the stations of the central part of the bay, while the lowest (<100 cysts/g) at the bay mouth. A good linear relationship is found between cyst amount and fine-grained sediments. Complex physiognomies on the seabed, topographty in the bay and weak water exchange are the main factors not only in cyst accumulation but also in their distribution pattern, and have resulted in the difference in cyst densities between the inner bay and the outer bay in the harbor.

    BACKGROUND: Choledochal cysts are classiifed into ifve types based on the location of the cyst. Mixed types of choledochal cysts are extremely rare. Only ifve cases of mixed typeⅠ andⅡ choledochal cysts have been reported, of which one was an adult case. We report a mixed typeⅠandⅡ choledochal cyst in a 25-year-old man. METHODS: The unusual nature of the choledochal cyst, suspected on magnetic resonance cholangiopancreatography RCP to be typeⅠ initially, was conifrmed by laparotomy to be a mixed typeⅠ+Ⅱ cyst. Excision of the cyst and hepaticojejunostomy were performed. RESULT: The operation was uneventful, and the patient recovered well. CONCLUSIONS: Mixed type choledochal cysts are rare, and may be missed on imaging, unless careful evaluation is done. The operative method may not need to be modiifed signiifcantly, as in the management of our case.

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

    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.

    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

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

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

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

    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.

    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.

    2014-01-01

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

    A 5-year-old neutered male domestic shorthair cat was presented for examination of a subcutaneous mass in his tail. The mass was firm, non-painful, oval, and approximately 2.5 × 3.5 cm. Surgical exploration revealed a well-circumscribed, encapsulated mass. The mass was removed and sectioned for histopathological examination. In gross section, it was filled with numerous dark hairs. Histologically the mass was consisted of haired skin with dermal cystic structures lined by stratified squamous epithelium. The cyst lumen contained squamous debris and filled with keratinous material. Numerous hair shafts were extended from the wall of the cyst. The sebaceous and apocrine gland adnexal structures were also observed which confirmed the diagnosis of dermoid cyst. No tumor recurrence was observed after surgery in fallowing checkups. Cutaneous or subcutaneous cysts of all types are considered rare in cats and to our knowledge this is the third reported case of cutaneous dermoid cyst of cats in veterinary literature which is different from the other cases because it occurred in dorsal midline in tail area whereas others occurred in flank area.

    Full Text Available 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.

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

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

    Full Text Available Hydatidosis due to Echinococcus granulosus is an endemic parasitic zoonosis characterized by worldwide distribution particularly in Mediterranean countries. The most commonly involved anatomical locations are the liver and lung. Occasionally the cyst may progressively increase in size, mimicking gross ascites or intrabdominal tumor. Herein, are reported a case of a 40-year-old patient with a giant exophytically expanded hepatic echinococcus cyst, misdiagnosed as an abdominal malignancy during formal investigation. The patient was admitted to the hospital complaining for mild diffuse abdominal tenderness, moderate abdominal pain, nausea, diarrhoea, and vomiting. A CT scan revealed the presence of a giant abdominal mass 25×21×14 cm, resembling a tumor, adherent to the liver edges and parietal peritoneum, displacing intestinal loops. During the ensuing days the patient’s clinical condition worsened, and he became febrile. Exploratory laparotomy was performed, and an exophytically grown giant liver hydatid cyst was removed, despite the radiological findings and the preoperative clinical suspicion.

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

  10. 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)

    Li, T.; Browne, R. M.; Matthews, J. B.

    1997-01-01

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

    Jaw cyst lining cells have an active transporting mechanism for Na+ ion and K+ion, a secreting mechanism and a selecting mechanism, and they allow permeation of electrolytes, lipids and protein into cysts. The components within the cysts have a controlling metabolism, and keep the system stable. Tumour wall cells of cystic ameloblastoma have only a passive transporting mechanism for various substances. Their nature differs from that of jaw cyst lining cells.

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

    Toxoplasma gondii infects up to one third of the world's population. 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

    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.

    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)

    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.

    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.

    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

    2016-04-01

    Primary bone tumors of the spine are less common than metastases or multiple myeloma. Based on the patient's age and the radiologic pattern and topography of the tumor, a very approximate differential diagnosis can be established for an osseous vertebral lesion. This article shows the radiologic manifestations of the principal primary bone tumors of the spine from a practical point of view, based on our personal experience and a review of the literature. If bone metastases, multiple myeloma, lymphomas, hemangiomas, and enostoses are excluded, only eight types of tumors account for 80% of all vertebral tumors. These are chordomas, osteoblastomas, chondrosarcomas, giant-cell tumors, osteoid osteomas, Ewing's sarcomas, osteosarcomas, and aneurysmal bone cysts.

    Full Text Available The term residual cyst is used most often for retained radicular cyst from teeth that has been removed. Residual cysts are among most common cysts of the jaws. The location of all odontogenic cysts is usually intraosseous. The peripheral (extraosseous presentations are rare. The peripheral presentation of residual cyst has never been reported in the literature. In this article, the role of CT in diagnosing an unusual peripheral presentation of a residual cyst is discussed.

    2013-02-01

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

    Directory of Open Access Journals (Sweden)

    Ana Maria Abreu Velez

    2011-01-01

    Full Text Available Context : Trichilemmal (pilar cysts are common skin lesions that often present on the scalps of mature men and women. These cysts often become inflamed when the wall of the cyst ruptures, but few reports have addressed the immunologic features of this process. Case Report: A 22-year-old female presented with rapidly growing nodule on her left cheek, with evidence of acute inflammation. Skin tissue for hematoxylin and eosin examination, as well as for immunohistochemical analysis was taken and reviewed. As controls, we utilized two archival, non-inflamed trichilemmal cysts. Hematoxylin and eosin staining demonstrated classic features of an inflamed trichilemmal cyst. No cytologic atypia was noted, and no significant number of mitotic figures was identified. Immunohistochemistry stains revealed that several cell cycle/tumor suppressor/apoptotic markers, antigen presenting cell markers, metalloproteinases and T cell response markers were highly expressed inside and around the disrupted cyst. The control, non-inflamed cysts were negative for the same markers. CD1a was also appreciated within the epidermis, suprajacent to the inflamed cyst. Conclusions : Upregulation and/or downregulation of selected cell cycle regulator and/or tumor suppressor/apoptotic markers, as well as antigen presenting cells and some protein kinases could recruit and activate T lymphocytes and other inflammatory cells to the non-disrupted cyst for unknown reasons. The immune response may be involved in the initial cyst rupture, or induced by an unknown alteration in the cyst. Larger studies are needed to address these questions.

    Full Text Available Abstract Background To review the clinical and pathological characteristics of median raphe cysts and to classify the lesions according to pathogenesis and histopathological findings. Methods The medical records of patients who were diagnosed with median raphe cysts between 2001 and 2010 were reviewed to document the clinical presentation and pathological findings of the cysts. Results Most patients were asymptomatic; however, 9 patients had inflammatory or infectious cysts that were tender or painful. Four patients who had cysts on the parameatus and distal prepuce had difficulty voiding. Hematuria and hematospermia were noted in 2 cases. Thirty-one cysts were lined with an urothelium-like epithelium, and a squamous epithelium lining was found in 3 cases. In 2 cases, a well-formed mucinous glandular structure was observed. The other 20 cysts consisted of mixed epithelia. After excision of the cysts under local or general anesthesia, an urethral fistula developed as a complication in only 1 case. Conclusions Median raphe cysts are benign lesions formed due to tissue trapping during the development of urethral folds. The cysts can be defined into 4 types based on pathological findings: urethral, epidermoid, glandular, and mixed. The associated symptoms and signs should be taken into consideration when determining the treatment for the cysts.

    Full Text Available Background: Odontogenic cysts and tumors are lesions that tend to arise from the tooth apparatus or its remnants. Odontogenic cysts and tumors constitute an important aspect of oral maxillofacial pathology as they can be diagnosed in general dental practice. Aim: The purpose of this study was to evaluate the prevalence of odontogenic cysts and tumors diagnosed in the UAE and to compare the results with findings in the literature. Materials and Methods: Data of odontogenic cysts diagnosed between 1990 and 2010 were collected from the files of the Oral Pathology Laboratory and Oral Surgery Department of Tawam Hospital, UAE. Results: Most of the prevalent odontogenic cysts are radicular cysts (69.1% - followed by dentigerous cysts (7.9%. Among the odontogenic tumors, the most prevalent is odontoma (12.2% followed by ameloblastoma (2.9%. The middle and posterior mandible was the most common anatomic site for the formation of cysts and tumors. In fact, 93.4% of patients over 40 years presented with odontogenic cysts, whereas 6.3% presented with odontogenic tumor. Odontoma as odontogenic tumor was seen mostly in the first and second decades of life. Conclusion: The prevalence of odontogenic cysts was similar to that reported in the literature, with inflammatory cysts occurring most frequently.

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

    We present our experience in the management of choledochal cysts from 1999 to 2009. A retrospective review of all charts with a diagnosis of choledochal cysts in our institution in this ten-year period. Data was collated using Excel. A total of 17 patients were diagnosed with choledochal cyst: 9 females and 8 males. The average age at diagnosis was 28 months (range from 0 to 9 years). The most common presenting symptoms were obstructive jaundice 6 (35%) and abdominal pain and vomiting 4 (23%). Ultrasound (US) was the initial diagnostic test in all cases with 4 patients requiring further investigations. All patients underwent Roux-en-Y Hepaticojejunostomy. The average length of stay was 11 days. Patients were followed up with Liver Function Tests (LFTS) and US 4-6 weeks post-operatively. Three patients developed complications including post-op collection, high drain output requiring blood transfusion and adhesive bowel obstruction. Our overall experience with choledochal cyst patients has been a positive one with effective management and low complication rates.

    Jiménez Urueta Pedro Salvador

    2014-07-01

    Full Text Available Background. Choledochal cyst is a rare abnormality. Its esti- mated incidence is of 1:100,000 to 150,000 live births. Todani et al. in 1981 reported the main objection for performing a simpler procedure, i.e., hepaticoduodenostomy, has been the risk of an “ascending cholangitis”. This hazard, however, seems to be exaggerated. Methods: A laparoscopic procedure was performed in 8 consecutive patients with choledochal cyst between January 2010 and Septem- ber 2012; 6 females and 2 males mean age was 8 years. Results. Abdominal pain was the main symptom in everyone, jaundice in 1 patient and a palpable mass in 3 patients. Lapa- roscopic surgical treatment was complete resection of the cyst with cholecystectomy and hepaticoduodenostomy laparoscopy in every patient. Discussion and conclusion. A laparoscopic approach to chole- dochal cyst resection and hepaticoduodenostomy is feasible and safe. The hepaticoduodenal anastomosis may confer additional benefits over hepaticojejunostomy in the setting of a laparoscopic approach. The creation of a single anastomosis can decrease operative time and anesthetic exposure.

It occurs exclusively within the retrorectal space and rarely in the perirenal area or in the subcutaneous tissue. A prerectal and retrovesical location of tailgut cyst is extremely rare. To the best of our knowledge, only three cases have been reported in the English literature. We experienced an unusual case of tailgut cyst developed in the prerectal and retrovesical space in a 14-year-old boy. Abdominal computed tomography demonstrated a prerectal cyst which was located at the anterolateral portion to the rectum. The cyst contained yellowish inspissated mucoid material. Microscopically, the cyst was lined by squamous, columnar, cuboidal and transitional epithelia and the wall was fibrotic with dispersed smooth muscle cells. Although tailgut cyst arising in prerectal area is extremely rare, its possibility should be considered in differential diagnosis of a prerectal and retrovesical cystic mass. PMID:16937513

    Acute bleeding within a colloid cyst of the third ventricle represents a rare event causing sudden increase in the cyst volume that may lead to acute hydrocephalus and rapid neurological deterioration. We report a case of spontaneous rupture of haemorrhagic third ventricular colloid cyst and its management. A 77-year-old ex-smoker presented with unsteady gait, incontinence and gradually worsening confusion over a 3-week period. Brain CT scan findings were highly suggestive of a third ventricular colloid cyst with intraventricular rupture. He underwent cyst excision and histopathology, which confirmed the radiological diagnosis with evidence of haemorrhage within the cyst. A ventriculo peritoneal shunt was performed for delayed hydrocephalus. Surgical management of these patients must include emergency ventriculostomy followed by prompt surgical removal of the haemorrhagic cyst.

    Full Text Available Cystic lesions of vagina are relatively uncommon and an incidental finding during routine gynaecological examination. Mullerian cysts are congenital cysts of vagina, usually reported during childbearing age group. These cysts mostly arise at the level of cervix and extend anteriorly in relation to bladder, but very rarely they may also extend posteriorly. This is a rare case of posterior vaginal wall cyst of Mullerian origin. A 36-year-old multi para (P2L2 both SVD, presented with a mass descending through vagina since 2-3 months. Pelvic examination revealed a 5x5 cm cystic mass arising from the posterior vaginal wall. Complete excision of the cyst was done. The cyst was filled with chocolate coloured material and histopathology confirmed a Mullerian cyst. [Int J Reprod Contracept Obstet Gynecol 2015; 4(1.000: 245-246

    To investigate the distribution, abundance, and species composition of dinoflagellate cysts in the Yellow Sea, surface sediment samples were collected at 37 sites, including the Korean dump site. Twenty-one di-noflagellate cyst taxa were identified, with the assemblages dominated mainly by Spiniferites bulloideus, Operculodinium centrocarpum, and cyst of Alexandrium catenella/tamarense type. A high frequency of O. centrocarpum in the Yellow Sea was observed for the first time, and it is likely that this can be attributed to the dynamics of the Yellow Sea Cold Water Mass and the Changjiang (Yangtze) River runoff. Total cyst concentrations ranged from 23 to 48 442 cysts/g dry weight, and high cyst concentrations were recorded adjacent to the dumping site. This result suggests that anthropogenic activities such as ocean dumping s-timulate the growth of dinoflagellates in the Yellow Sea, which in turn leads to high levels of dinoflagellate cyst production.

    Pineal cysts, both simple and complex, are commonly encountered in children. More cysts are being detected with MR technology; however, nearly all pineal cysts are benign and require no follow-up. To discover the prevalence of pineal cysts in children at our institution who have undergone high-resolution 3-T MRI. We retrospectively reviewed 100 consecutive 3-T brain MRIs in children ages 1 month to 17 years (mean 6.8 {+-} 5.1 years). We evaluated 3-D volumetric T1-W imaging, axial T2-W imaging, axial T2-W FLAIR (fluid attenuated inversion recovery) and coronal STIR (short tau inversion recovery) sequences. Pineal parenchymal and cyst volumes were measured in three planes. Cysts were analyzed for the presence and degree of complexity. Pineal cysts were present in 57% of children, with a mean maximum linear dimension of 4.2 mm (range 1.5-16 mm). Of these cysts, 24.6% showed thin septations or fluid levels reflecting complexity. None of the cysts demonstrated complete T2/FLAIR signal suppression. No cyst wall thickening or nodularity was present. There was no significant difference between the ages of children with and without cysts. Cysts were more commonly encountered in girls than boys (67% vs. 52%; P = 0.043). There was a slight trend toward increasing pineal gland volume with age. Pineal cysts are often present in children and can be incidentally detected by 3-T MRI. Characteristic-appearing pineal cysts in children are benign, incidental findings, for which follow-up is not required if there are no referable symptoms or excessive size. (orig.)

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

  5. Lumbar intraspinal juxtafacet cysts: MR imaging and CT-arthrography

    International Nuclear Information System (INIS)

    Purpose: To present data on the MR imaging appearance of lumbar intraspinal juxtafacet cysts (JFC) and to assess the importance of additional CT arthrography. Material and Methods: Twenty-eight patients (16 women, 12 men) with a mean age of 64 years (range: 43-82), who underwent MR imaging because of radicular pain or spinal claudication, were found to have an intraspinal cyst associated with the facet joint. In 14 patients, additional CT-arthrography was performed to determine whether a communication exists between the cyst and the facet joint and to try to rupture the cyst. Results: In T2-weighted images, juxtafacet cysts show a typical pattern consisting of a hyperintense center and hypointense rim. The center is likely to be inhomogeneous because of recurrent hemorrhage in the cyst. In T1-weighted images, the cysts are hypo/isointense. Irregular hyperintensity may indicate subacute hemorrhage, which may aggravate the clinical symptoms. MR allows superior visualization of the cyst in all anatomical planes. It also enables assessment of typical accompanying changes, such as degenerative spondylolisthesis and facet hypertrophy. All patients, who had CT-arthrography, were found to have a direct communication between joint space and cyst. Transarticular rupture of the cyst was possible in five patients. Two of these five patients had good to excellent improvement, and the remaining three patients underwent surgery. (orig.)

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

    Background Choledochal cyst is rare in western countries. The relatively high incidence of coexistent hepatobiliary disease increases the difficulty of the surgical management of choledochal cyst. Here we analyze the diagnosis and treatment of congenital bile duct cyst in 122 Chinese adults.Methods The clinical data of 122 patients with congenital choledochal cysts admitted from 1981 to 2006 were analyzed.Results Clinical symptoms in most cases were nonspecific, resulting in delayed diagnosis. Sixty-one patients (50%) had coexistent pancreatobiliary disease. Among the 122 patients, 119 patients underwent ultrasonic examination;ERCP/MRCP was performed in 63 cases and CT in 102 cases. Abnormal pancreatobiliary duct junction was found in 48 patients. Sixteen patients had malignant lesions in the bile duct, arising in 11 of them from incomplete choledochal cyst that underwent various operations including cystenterostomy or cystojejunostomy. There was significant difference between the patients who underwent incomplete cyst resection and complete cyst resection in malignancy rate of bile duct (Chi square test, P= 0.000; odds ratio, 7.800; 95 % confidence interval, 2.450 to 24.836).Conclusions ERCP, CT and MRCP had proved their great values in the classification of the disease. Cyst excision with Roux-en-Y hepaticojejunostomy is recommended as the treatment of choice for patients with type Ⅰ or type Ⅳ cysts. For type Ⅴ cyst (Caroli's disease) with recurrent cholangitis, liver transplantation should be considered.

    Plasma cell tumors are lymphoid neoplastic proliferations of B cells. Multiple myeloma is the disseminated type of this disorder, while localized forms of plasma cell neoplasms are solitary plasmacytoma of bone that is observed as centrally localized in bones, and extramedullar plasmacytoma (EMP) that develops in soft tissues. EMP of the head and neck region is a rare malignant tumor comprising approximately 3% of all plasma cell tumors, and approximately 0.4% of all head and neck malignancies; among them, plasmacytoma of the maxilla is extremely rare. The authors present a case of a patient affected by an EMP of the maxilla simulating a maxillary radicular cyst comparing our results with the recent literature. EMP entity requires a meticulous overview of the patient by the specialist and overall the control of any signs or symptoms of systemic diseases, a fact that would mark a dramatic change in the treatment and prognosis for the patient.

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

    A 31-year-old Filipino active duty marine presented with a 2-year history of a waxing and waning nodule on his left cheek that had been incised and drained on multiple occasions. The patient had no significant medical history other than a positive purified protein derivative test with negative chest x-ray finding treated with a 9-month course of isoniazid in 2010. He denied cough, fever, chills, night sweats, weight loss, joint/bone pain, or prior trauma to the area. On initial examination, there was a 1×1-cm erythematous indurated nodule associated with an overlying violaceous scar on his left preauricular cheek. Since the lesion was presumed to be an inflamed epidermal cyst, it was initially treated with 0.1 cc of interlesional triamcinolone acetonide (10 mg/cc). At 1-month follow-up, the lesion was slightly less indurated, but an excisional biopsy was performed to remove the residual nodule. The biopsy showed an essentially normal epidermis with focal dermal fibrosis below which were multiple collections of histiocytes and multinucleated giant cells surrounded by a dense lymphoplasmacytic infiltrate with numerous eosinophils (Figure 1). A few multinucleated giant cells contained large thick-walled spherules, some with endospores, consistent with Coccidioides immitis (Figure 2). Serological tests showed positive serum for C immitis IgG antibodies with low levels of complement-fixing antibodies (1:2). IgM antibodies were negative. Findings from chest x-ray and bone scan failed to reveal evidence of systemic disease. Although the infectious disease physician felt that the patient most likely had primary cutaneous coccidioidomycosis (PCC), since the duration of the infection was unknown and the patient was Filipino, thereby increasing his risk of dissemination, he was placed on a daily regimen of 400 mg of oral fluconazole until his complement fixation titers became undetectable.

    We describe the imaging findings in 3 children with choroid plexus cysts (CPC) at the foramen of Monro. All CPC measured less than 2 cm and produced symptoms of raised intracranial pressure when located at the foramen of Monro where there was obstruction to the cerebrospinal fluid (CSF) flow. Two of our patients had relief of symptoms after resection of the cyst. One patient with inoperable cardiac defects died and had no surgery performed. Cranial sonography and CT-ventriculography are the modalities of choice in evaluating ventriculomegaly when the diagnosis of occult obstructive CPC is entertained in children. Cranial sonography is indicated in infants with an open fontanelle and CT-ventriculography is reserved for older children with hydrocephalus which is not responding to shunting. (orig./GDG).

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

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

    Full Text Available Introduction Calcifying odontogenic cyst (COC is a unique and uncommon odontogenic cyst classified into four groups of cystic, odontoma producing, ameloblastomatous proliferating and neoplastic ones. Case Presentation A 34-year-old Iranian man complaining of a painless facial and palatal swelling of the left side of the maxilla persisted for approximately three years was referred to the department of oral and maxillofacial surgery, Hamadan University, Iran. Panoramic film revealed a well-defined multilocular mixed radiolucent and radioopaque lesion of the maxilla at the left side. An incisional biopsy was obtained. Based on the histopathologic findings, ameloblastomatous COC was diagnosed. Discussion We reported a rare case of COC. According to Praetorius et al. classification, this patient comes under the category of type 1C (ameloblastomatous proliferating. Many patients with ameloblastomatous COC should be reported to understand its biological behavior as possible.

    Glandular odontogenic cysts (GOCs) are rare intrabony solitary or multiloculated cysts of odontogenic origin. The importance of GOCs lies in the fact that they exhibit a propensity for recurrence similar to keratocystic odontogenic tumors and that they may be confused microscopically with central mucoepidermoid carcinoma. Thus, the oral and maxillofacial radiologists play an important role in definitive diagnosis of GOC based on distinctive cases; though they are rare. In large part, this is due to the GOC's complex and frequently non-specific histopathology. This report describes a case of GOC occurrence in the posterior mandibular ramus region in a 17-year-old female, which is a rare combination of site, age, and gender for occurrence.

    2015-01-01

    Cystic lesions of the pancreas (CLPs) are increasingly diagnosed due to the growing utilization of cross-sectional imaging modalities. The differentiation between true cysts (epithelial tumors) and nonepithelial lesions (such as pseudocysts) relies on clinical and imaging characteristics, but more reliably obtained by endoscopic ultrasound (EUS) fine-needle aspiration. Due to their malignant potential, some of the true pancreatic cysts require further assessment and periodic follow-up. Therefore, it is important to establish a solid diagnosis at the time of detection of the various types of pancreatic cysts. Due to the limitations of cytology and biochemical markers in accurately classifying cyst pathology, the search for specific molecular markers associated with each type of cyst is ongoing. In this chapter, we will review some of the emerging molecular markers in pancreatic cystic fluid and their potential impact on endosonography and pancreatic cyst management. PMID:26643693

    Full Text Available Introduction. The presence of a serous cyst in the tympanic membrane implies the description of a new or unpublished entity based on our knowledge whose origin may be very unlikely explained on actual embryologic and anatomic background. Clinical Case. We present a case of a 45-year-old woman with progressing right hearing loss. Physical examination revealed a whitish, round-shaped malformation in the posterior-inferior quadrant of the right tympanic membrane. The cyst was removed with a transcanal tympanoplasty. Discussion. A thorough PubMed search that involved the terms tympanic membrane gland, epithelial inclusion cysts, mucous-secreting cyst, and tympanic cyst has shown no positive results. The first description of an unknown entity, such as a tympanic membrane serous cyst, may be the key for clinicians to start paying attention to patients who suffer from similar pathologies and may pass unnoticed because of their rarity or peculiarity.

    2012-02-01

    Splenic cysts are relatively uncommon, and are usually asymptomatic. They are benign, typically treated conservatively and followed up with ultrasound examination, with few reported complications. We report a case of a simple splenic cyst that was followed up on imaging over a seven-year period. During that time, the cyst gradually enlarged from 5 cm to 12 cm in diameter, however the patient remained asymptomatic. After seven years, the patient was admitted with abdominal pain and a pelvic mass. The spleen was located within the pelvis, which was felt to be due to the weight of the cyst which caused the spleen to migrate out of its normal position. This case illustrates an extremely unusual complication, and suggests that while most splenic cysts may be managed conservatively, enlarging cysts may be prone to gravitational effects and prophylactic treatment should be considered.

    Full Text Available Paediatric penile cysts are uncommon. We report a five-year-old child with an asymptomatic progressively growing cyst on the ventral aspect of the penis after a hypospadias repair. The patient presented to the Cooper Health Clinic, Dubai, United Arab Emirates, in March 2012. A complete excision of the cyst was performed. Histology results delineated a capsulated benign trichilemmal cyst. No recurrence or complications were reported in the 26 months following the excision. We recommend an early and complete excision of all penile cysts to prevent the risk of urethral obstruction, infection, inflammation and rare malignant changes. This is the first reported case of a penile trichilemmal cyst in a child.

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

    As technology advances, the techniques of laparoscopic surgery are being refined and their aplication is expanding to include many disease processes and organs. The new-generation laparoscopic instruments are becoming smaller (less than 5 mm). Expected advantages include improvements in cosmesis and patient satisfaction, and decreased postoperative analgesic requirements. Non-neoplastic cysts of the spleen are rare, and their management has evolved from total open splenectomy to laparoscopic ...

    Several diseases cause cystic or cyst-like parenchymal lung abnormalities including adult pulmonary Langerhan’s cell histiocytosis (PLCH), lymphangioleiomyomatosis (LAM), emphysema, end-stage interstitial lung disease, and cystic bronchiectasis. Many of these diseases can now be diagnosed with high accuracy by the use of high-resolution computerized tomography (HRCT). In fact, HRCT of chest has proved a major breakthrough in the diagnosis of these diseases. We are presenting a young man with ...

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

    In connection with their two own cases, the authors deal about the giant cholesterol cysts of the petrous apex. The lesions which are to be differentiated from epidermoid cysts are cholesterol granulomas. Their petrous apex location explains their characteristic large appearance. As each cholesterol granuloma, they occur when a bony cell is obstructed. This chronic obstruction induces mucosal edema then bleedings which lead to the formation and, by the lack of drainage, to the accumulation of cholesterol crystals. These crystals initiate a non specific reaction to foreign bodies, a granuloma, which also can bleed. Thus, a continuous cycle perpetuates the growth of the lesion. This lesion, when it is localized in the petrous apex, can reach a big size before the appearance of some signs. Usually, these are otologic (sensorineural hearing loss, tinnitus, vertigo) and/or cranial nerve palsies (V, VI, VII). C.T. scan (well defined, sharply marginated bony expansible lesion with isodense to the brain central part) and M.R.I. (central region of increased intensity on both T1 and T2 weighted images and peripheral rim of markedly decreased signal intensity in all instances) features are characteristic enough to allow diagnose with other petrous apex lesions (cholesteatoma, mucocele, epithelial cyst, histiocytosis X, ...). Surgical treatment must try to evacuate and to aerate the cavity or perhaps to obliterate it with fatty pieces in order to prevent the recurrence. PMID:1299772

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

    Full Text Available Primary hydatid cyst in the pelvis is rare, and usually presents with pressure symptoms affecting the adjacent abdominal organs. We describe a rare hydatid cyst which was eroding the sacral hallow, protruding into the right sciatic foramen and presenting as a radiating pain and weakness of right lower limb due to compression of the lumbosacral nerve roots. Laparotomy with removal of cyst and postoperative treatment with albendazole is effective in controlling the disease and preventing recurrence.

    Developmental foregut cysts, whether bronchogenic, esophageal, gastroenteric or pericardial, are frequently encountered in the mediastinum, and are also occasionally found in the upper abdomen, where they can mimic adrenal, pencreatic, renal or gastric masses. We present the computed tomographic (CT) and histologic findings of an intramuscular bronchogenic cyst of the gastric body, mimicking a retroperitoneal cystic mass. CT scanning demonstrated the presence of a relatively hyperattenuating cystic mass without enhancement. Histologic examination revealed a bronchogenic cyst secreting mucoid materials.
