Detailed study of fine structure of intracranial hemangiopericytoma shows that this neoplasm, formerly designated as capillary “angioblastic meningioma,” conforms in all respects to hemangiopericytomas encountered in other organ systems. Ultrastructural features of intravascular cells in transitional type “angioblastic meningioma” were similar to those described for meningiomas in general. The present observations reemphasize the possibility of a histogenetic relationship between intracranial hemangiopericytoma and hemangioblastoma and suggest the exclusion of both of these variants of vascular tumors from the group of meningiomas.
