PURPOSE: To study the imaging findings of meningeal hemangiopericytomas. MATERIAL: and method: Four cases of meningeal hemangiopericytomas are reported, two involving the spine and two intracranial in location. RESULTS: An extra-axial and heterogeneous pedunculated mass, without calcification should suggested a diagnosis of hemangiopericytoma especially if a bone erosion is noted; meningioma is the main differential diagnosis. CONCLUSION: CT scan as well as MR imaging are not specific but may provide findings consistent with a diagnosis of hemangiopericytoma. A long follow up of these patients is required because of frequent recurrences and delayed metastases.
