Hemangiopericytoma is a vascular neoplasm of variable and unpredictable malignancy, composed of proliferating capillary pericytes surrounding endothelial-lined tubes or sprouts. The histological appearance is diagnostic. The treatment of primary intracranial hemangiopericytoma is surgical excision, supplemented by radiotherapy. Local tumor recurrence after many years is common, and late and widespread metastasis can occur. Long-term follow-up is mandatory.
