title: An unexpected lesion in cerebellopontine angle: hemangiopericytoma.
abstract: hemangiopericytoma (hPC) is a rare tumor by definition and intracranial hPC makes up to less than one percent of all the intracranial tumors. It is a dural base tumor and its clinical features and radiological findings are similar to meningiomas. however, cerebellopontine angle hemangipericytoma had only been reported twice and would almost always be misdiagnosed. definite diagnosis is important, as the treatment of hPC is different from meningiomas and acoustic neuromas. we report a case of a young female who presented with atypical symptoms of left cerebellopontine angle mass. A literature review of the nature of the disease, radiological findings, immunohistochemical features and treatment options of the tumor are described.
