[Simple bone cysts in childhood. Retrospective study of 15 cases and review of literature].

We present a review of 15 cases of simple bone cyst treated by curettage and bone grafting or intralesional steroids injection. We analysed the localisation, cyst activity, the number of cavities and the occupied area, valuing the results according to the Neer and Chigira classification. We have noticed a higher rate' of cure with curettage and bone grafting than with steroids injection (p: 0.01). The activity of the cyst, the uni-multilocutarity and the area related to a greater index of recurrence and failure in the cases treated by steroids injection, although this is statistically non significant.

Unusual jaw-bone cysts.

Four cases of unusual types of jaw-bone cysts (paradental, lateral periodontal/botryoid type, sialo-odontogenic, and intraosseous dermoid cyst) are reported. Radiographic and histopathologic features are described. Current literature is reviewed with special attention given to radiographic, histogenetic, and histopathologic aspects of these entities.

Radiological and clinical features of aneurysmal bone cyst of the jaws.

PURPOSE: To evaluate the clinical and radiological features of aneurysmal bone cyst (ABC) of the jaws. MATERIALS AND METHODS: A total of 64 cases (60 from the English-language literature and four new cases) were studied and critically evaluated with emphasis on the radiological features. RESULTS: Age at time of initial diagnosis ranged from 4-78 years, with a mean age of 21.5 years and median age of 17 years. There were no differences in gender distribution. The ratio between the mandible and maxilla was 2.4:1. Ninety-two per cent of the lesions were located in the posterior region of the jaws. Lesions were radiolucent in 87% of cases, radiopaque in 2% and mixed in 11%. Fifty-three per cent were multilocular, 43% unilocular and 3% not loculated. The border of the lesions was defined but not corticated in 39%, well defined in 33% and diffuse in 28%. CONCLUSIONS: ABC has a variable radiological appearance and should be considered in the differential diagnosis of any unilocular or multilocular radiolucent lesion of the jaws as well as any mixed radiolucent-radiopaque lesion.

Unicameral bone cyst in the scapula.

This is a case report of a 21 year old man with a unicameral bone cyst of the scapula. The occurrence here, as in other flat bones, is rare. The unusual location presents a diagnostic problem, but as in other flat bones, the prognosis after treatment by bone grafting is very good.

[Stimulated osteogenesis in bone cysts].

This method deduces from classical therapeuticál principle of bone jaw cysts from Partsch (1892, 1910) and Schulte (1959, 1960, 1964) and has regard the modern results of biomaterial research. It is used mixing of anorganic and organic materials, which proportion is in accordance to normal bone tissue. In 39 till now operated cases of different bone defects we attained good clinical events. The first cases are controlled since two years.

Aneurysmal bone cyst of the atlas: successful treatment through selective arterial embolization: case report.

OBJECTIVE AND IMPORTANCE: Aneurysmal bone cysts (ABCs) are benign and expansile osteolytic lesions that can occur in any location in the spine, including the craniovertebral junction. Aggressive resection followed by bone grafting has been the mainstay of treatment, with selective arterial embolization as a presurgical adjunct. Complete excision of these lesions at the craniovertebral junction is associated with high surgical morbidity. We report a case of successful treatment of an ABC of the atlas in a child with selective arterial embolization alone. CLINICAL PRESENTATION: A 10-year-old girl presented with persistent neck pain after a snowboarding accident. Computed tomography and magnetic resonance imaging of the cervical spine revealed an expansile cystic mass involving the right lateral mass of C1. Digital subtraction angiography revealed a tumor blush, which, along with the cystic appearance of the lesion, was consistent with an ABC. INTERVENTION: The arterial feeders to the lesion were selectively embolized with polyvinyl alcohol particles. Three sessions of embolization were required to eradicate the blood supply to the lesion completely. CONCLUSION: Complete surgical resection of ABCs at the craniovertebral junction can be associated with high morbidity secondary to the highly vascular and destructive nature of these lesions. The case discussed here demonstrates the viability of selective arterial embolization as a primary and stand-alone modality of treatment.

Solitary bone cyst of the jaws: radiographic review of 44 cases.

Solitary bone cyst is a radiolucent lesion classified as a pseudocyst with a variety of reported shapes including round, oval, and irregular. In the long bones, a truncated cone shape has been described, and the fallen trabecula sign is seen in association with pathologic fracture. The purpose of this study was to classify and document the various shapes, to describe the width versus height dimensions of jaw SBCs, to determine the identifying signs of trauma, and to evaluate other reported radiographic features. Radiographs of 44 SBCs in 43 patients were studied. Sixty-four percent demonstrated the cone shape, and four subtypes of this shape were identified. Other shapes included oval (16%), irregular (16%), and round (4%). Radiographic signs of trauma were observed in 28% of the cases. No evidence of the "fallen trabecula sign" was found in this series.

Amyloid bone cysts of the femoral neck. Impending fractures treated by curettage and bone grafting.

We performed curettage and bone grafting of amyloid cysts of the femoral neck in five patients on long-term haemodialysis. All had had hip pain on weight-bearing. The duration of haemodialysis before the operation averaged 15 years and the average age of the patients was 53 years. All the large cystic lesions were located in the anterosuperior quadrant of the femoral neck. At operation, they were found to consist of fibrous tissue containing amyloid deposits. Postoperatively, all five patients had painless hips and the grafts had incorporated into the bone defects.

Aneurysmal bone cyst of the skull.

A case of a 48-year-old woman with aneurysmal bone cyst of the skull is reported. By using estrogen, which is one of the chemical embolizing agents, the abnormal vascular shadow disappeared and clinical symptoms were improved. The significance of selective external carotid angiography in the diagnosis of this lesion is discussed and the benefit of this therapeutic method is argued.

[Aggressive aneurysmal bone cyst in childhood (author's transl)].

Case presentation of a four year old child with aggressive aneurysmal bone cyst of the fourth lumbar vertebra. Microscopic examination demonstrates a benign lesion. The roentgenographic pattern reflects a tumorlike bone destruction with signs of malignancy. Clinically, progression and invasion, similar to a semimalignant tumor, is noticed. The possible nature of this aggressive behaviour is discussed.
