Cavernous Hemangioma of the Middle Fossa : -Case Report and Review of the Literature-

概要

A 70-year-old female was treated surgically for an extracerebral cavernous hemangioma of the middle fossa. The literature contains reports of one autopsy and 20 operative cases of cavernous hemangioma of the middle fossa. We compared these cases with cerebral cavernous hemangiomas and found that the incidence is high in Japanese females and in individuals over 20 years of age (average age, 43 years). Signs and symptoms are usually disturbed visual acuity or ocular movement rather than manifestations of increased intracranial pressure. Plain x-rays showed destruction of the sella without hyperostotic changes of the sella or the middle cranial fossa. CT scans showed isodensity/high-density areas of a dumbbell configuration, with the smaller part in the sella and the larger part in the middle fossa. Other CT features were contrast enhancement and evidence of atrophic processes in the surrounding brain. Conventional angiography showed an avascular mass lesion, but tumor staining was demonstrated only by prolonged injection, selective angiography, or subtraction. A review of the literature and our own operative findings suggest that the origin of this tumor is the cavernous sinus. Total removal of such tumors is difficult because of profuse intraoperative bleeding, and operative mortality is high (38%). It should be stressed that correct preoperative diagnosis is very important in decreasing operative deaths.
