title: [Malignant hemangiopericytoma in computed tomography].
abstract: CT findings of eight malignant hemangiopericytomas are presented. CT revealed well-circumscribed mass lesions in five cases, whereas three tumors showed invasive growth. Cystic areas were found in four hemangiopericytomas, and a dystrophic calcification was seen in one case. Following intravenously injected contrast material, all tumors demonstrated a distinct enhancement.
