title: Cerebellar hemangioblastoma with clear nuclei. Case report and ultrastructural study.
abstract: A case of cystic cerebellar hemangioblastoma with previously unreported light and electron microscopic features is reported. Deposits of intranuclear, osmiophilic, lipid-like material produced unusual stromal cells, with distended clear nuclei similar to empty cysts at the light-microscopic level. This description expands the morphologic spectrum of this rare tumor.
