Abstract
Supratentorial hemangioblastoma is encountered very rarely. About 60 cases in all have been reported. The authors present a case of supratentorial hemangioblastoma and cerebellar hemangioblastoma occurring 7 years after surgery for spinal hemangioblastoma.
A 23-year-old male was admitted with severe headache and vomiting. Neurological examination showed paraplegia, left cerebellar disturbance, and horizontal nystagmus on lateral gaze to the left. Computerized tomography scans and bilateral axillar artery angiograms showed a left cerebellar cystic mass with two mural nodules. In consequent operations, two hemangioblastomas were found; one in the left cerebellar hemisphere and the other attached to the cerebellar tentorium under the left occipital lobe. The histology of these tumors revealed the well-differentiated morphology of hemangioblastomas. The authors discuss some clinical aspects of the supratentorial hemangioblastoma associated with infratentorial or spinal hemangioblastoma, and also the differential diagnosis between angioblastic meningioma and hemangioblastoma.
