title: Intracranial hemangiopericytoma with extracranial metastasis occurring after 22 years.
abstract: A 65-year-old man developed pancreatic and pubic tumors 22 years after craniotomy for a left sphenoid ridge tumor. The histological finding of the primary sphenoid ridge tumor was meningotheliomatous meningioma. The histological appearance of the biopsy specimen of the pubic tumor was hemangiopericytoma. The recurrent intracranial tumor was treated by radiosurgery, and the metastatic tumors were treated by conventional irradiation. Intracranial tumors rarely metastasize outside the central nervous system, except for meningeal hemangiopericytomas. This case indicates that meningeal hemangiopericytoma may metastasize many years after the initial onset and requires long-term follow up.
