DOI : 10.5505/tjo.2017.1536 Intracranial meningeal hemangiopericytoma is a rare vascular tumor with a high rate of both local recurrence and the development of distant metastases. The aim of this report is to present the first case of recurrent meningeal hemangiopericytoma with an isolated femur metastasis and discuss the clinical features and treatment of this rare tumor. A 46-year-old woman was admitted with the complaint of sudden loss of consciousness and subsequently underwent an urgent craniotomy with total excision of the lesion. The diagnosis was meningeal hemangiopericytoma. The patient presented with a painful left hip 5½ years after the initial surgery for the primary tumor. A lytic lesion, which was 4x4.5 cm in diameter, was seen on an X-ray of the proximal left femur. The patient underwent lesion removal surgery and pathological diagnosis was compatible with meningeal hemangiopericytoma. At 69th month, no progression has been observed in follow-up. Long-term follow-up is mandatory for meningeal hemangiopericytoma due to high recurrence rate many years after diagnosis. Further multi-institutional studies are strongly needed to understand the clinical behavior and treatment modalities of this rare disease.
