A case of convexity cavernous hemangioma associated with meningioma

A case of convexity cavernous hemangioma associated with sellar meningioma with parasellar extension is presented. A 61-year-old female who had complained of left blepharoptosis and diplopia was admitted to our hospital. On admission she showed left oculomotor nerve palsy. Plain CT revealed an isodense mass in the sellar and parasellar region. Computed angiotomography demonstrated that this mass was enhanced heterogeneously and filled the sellar turcica and extended superiorly. And homogeneously enhanced mass in the convexity without mass effect was observed. Angiogram revealed no tumor stain in any phase. With these findings, this case was diagnosed as the multiple meningiomas preoperatively. Left frontotemporal craniotomy was carried out, and subtotal removal of sellar and parasellar tumor and total removal of convexity tumor were performed. Pathologically the sellar and parasellar tumor was diagnosed as meningioma, convexity tumor as cavernous hemangioma derived from dura mater. Convexity cavernous hemangioma derived from dura mater is very rare, only one case was reported previously. Only 2 cases of cavernous hemangioma associated with meningioma have been reported in the literature. Correlation between cavernous hemangioma and meningioma is discussed. It is possible to owe this complication to the developmental abnormality concerning with inner factor like genetic factor and so on, because both tumors are mesodermal origin. However it is proper to regard that this complication occurred by chance.
