Supratentorial hemangioblastoma in a child. Case report.

Hemangioblastomas are rarely seen in the supratentorial region, especially in childhood. The case of a 10-year-old boy with left parieto-occipital cystic hemangioblastoma is reported. The neoplasm was not attached to the dura, nor was it associated with von Hippel-Lindau syndrome or with erythrocythemia. Cerebral angiography showed no evidence of a vascularized tumor, whereas computerized tomography gave more accurate information. The gross and microscopic appearance of the lesion is described, and a review of similar cases previously reported in the literature is presented.
