متن کاملMorphologic patterns and imaging features of intracranial hemangiopericytomas: a retrospective analysis
OBJECTIVES Hemangiopericytomas (HPCs) are rare intracranial tumors. Their differential diagnosis using computed tomography (CT) and magnetic resonance imaging (MRI) is difficult because of similarities in morphologic features with other intracranial tumors and meningiomas. METHODS We retrospectively analyzed the clinical data and CT and MRI findings of 32 patients diagnosed with HPCs via hist...
متن کاملIntracranial Hemangiopericytomas : A Retrospective Study of 15 Patients with a Special Review of Recurrence.
OBJECTIVE Although surgical resection is used to treat meningeal hemangiopericytoma (MHPC), there is a high risk of subsequent recurrence. This study investigated factors associated with treatment outcomes and recurrence in patients who had undergone surgical resection of intracranial MHPC.

متن کاملIntracranial meningeal hemangiopericytomas in children and adolescents: CT and MR imaging findings.
Intracranial meningeal hemangiopericytomas in children and adolescents are prone to bleeding during surgery. CT and MR imaging may serve a role in preoperative diagnosis. The purpose of this report was to describe the radiologic findings in 9 pathologically proved cases of intracranial meningeal hemangiopericytomas in children and adolescents. The average duration of symptoms was short (mean, 4...
