This is a report of the clinico-pathologic findings in six cases of histologically verified malignant meningiomas-three hemangiopericytic and three anaplastic types. They were three males and three females and two of them were reoperated for recurrence. The hemangiopericytic types had similar angiographic and macroscopic features and malignant characteristics such as increased mitoses. The anaplastic types lacked typical arrangement, but had a large number of mitoses, increased cellularity, focal necrosis, pleomorphism, anaplasia, and the adjacent normal parenchymal infiltration. However the metastasis was not yet proven in these cases.
