Summary Aneurysmal bone cysts occurring within the calvarium are uncommon. The following case report describes the radiological and pathological findings of a temporal bone aneurysmal bone cyst with intra- and extracranial manifestations. The pertinent literature is reviewed. 相似文献

Aneurysmal bone cyst (ABC) of the temporal bone is rare. The nature of the underlying disorder that converted into the ABC might, however, be difficult to ascertain on imaging as well as on histopathology. The unusual CT and MRI findings in a case of ABC of the temporal bone are presented. This had transdural intracerebral spread with a large component of solid enhancing matrix but no peripheral calcific rim. The patient was an adult of 45 years with a history of headache for more than 1 year. 相似文献

BACKGROUND: Aneurysmal bone cyst (ABC) is a benign, expansive, osteolytic lesion that mainly occurs in young people, and involves the skull bones only exceptionally. The origin of ABC is controversial: secondary reactive bone lesion, or primary disease that represents an independent nosological entity. Blunt head trauma was suggested as a possible etiological factor. CASE REPORT: A case of a 19-year-old man with primary ABC of the right frontal bone was reported. The lesion was totally excised through frontal craniotomy, and the skull bone defect primarily reconstructed with an acrilate cranioplasty. Five years after the surgery, the patient was without signs of local recurrence. CONCLUSION: Clinical and neuroradiological presentation of the skull ABC was not specific. Pathohistology confirmed the diagnosis. Total excision was the treatment of choice. 相似文献

Aneurysmal bone cysts is a benign, slow growing expansile lesion usually found in long bones or vertebrae. Only 5 cases of ABC of the ethmoid bone have been reported in the literature. Plain radiographs are not specific. CT and MRI are very useful to depict the extent of the lesion and demonstrate the presence of blood-fluid levels, which is a characteristic finding of ABC. We present one atypical case of ABC of the ethmoid bone in a 15-year-old female characterised by its extensive involvement and its rare location. 相似文献

Aneurysmal bone cysts are benign fibrosseous lesions of the bone that are rarely detected in the temporal bone. Seventeen cases of aneurysmal bone cysts with histological confirmation involving the temporal bone were reported in the literature. We report a case of left temporal aneurysmal bone cyst in a 52-year-old male with the clinical findings of periauricular painful swelling, decreased hearing, and facial paralysis. A magnetic resonance image of the patient showed a well-circumscribed multi-loculated expansile lesion of the left temporal bone during the first admission to the hospital. The lesion recurred 1 year after the subtotal resection with a more solid appearance. In addition, we review the literature for these rare lesions. 相似文献

A correlated histologic and radiographic study of nine giant-cell tumors, six aneurysmal bone cysts, and one combined lesion is presented. Clinical findings and plain radiographic appearances were found to overlap. Angiographically, the giant-cell tumors were richly vascularized, with a marked intratumoral contrast uptake, occasional irregular tumor vessles, a prominent peritumoral arterial net-work, and early draining veins. Microscopic examination revealed fine, capillary-like and somewhat larger, angulated, sinusoid vessels, and occasional small, bloodfilled cysts within the tumor. Conspicuous arteries, veins, and capillaries surrounded the tumor. The aneurysmal bone cysts at angiography were predominantly avascular in the interior, surrounded by a thin hyperemic zone in the peritumoral tissue, with sometimes early filling of veins. Microscopically, the aneurysmal bone cysts showed large, anastomosing, bloodfilled vascular channels, and a moderate number of capillaries within the solid, fibrous areas and the granulation tissue. It is concluded that angiography, particularly with a subtraction technique, may be a valuable diagnostic method in the pre-operative differentiation of giant-cell tumors from aneurysmal bone cysts. 相似文献
