Abstract

Supratentorial hemangioblastoma is encountered very rarely, with only about 110 cases reported. This report concerns a case of a suprasellar hemangioblastoma associated with thoracic meningioma. A 62-year-old man was admitted with visual disturbance of the left eye. T2-weighted magnetic resonance imaging (MRI) showed a high signal intensity mass in the suprasellar region without perifocal edema. T1-weighted MRI with gadolinium showed a homogeneously enhanced mass. The angiogram revealed remarkable tumor staining originating from the right and left internal carotid arteries (ICA) and the left external carotid artery (ECA). On the basis of the pre-operative diagnosis of tuberculum sellae meningioma, total tumor removal was performed. Photomicrographs of the specimen showed numerous capillaries divided by stroma cells. Positive immunostaining for factor VIII related antigen (F VIII RAg) was observed in endothelial cells, but immunostaining for epithelial membrane antigen (EMA) was not observed in any cells. A diagnosis of suprasellar hemangioblastoma was made on the basis of these findings. The patient suffered paraparesis on the postoperative seventh day. Since MRI showed a thoracic tumor, a second total tumor removal was performed. The tumor was diagnosed as a meningothelial meningioma. The patient was discharged without evidence of new neurological deficits. Our experience shows that, when a mass is vascularized in the cerebral hemisphere, the possibility of hemangioblastoma needs to be taken into consideration.
