title: Meningeal hemangiopericytoma in childhood.
abstract: Meningeal hemangiopericytoma (MHP) is extremely rare in childhood. Mean age at diagnosis is between 38 and 43 years. We present an 8-year-old boy with MHP of the middle cranial fossa. Imaging findings were indistinguishable from an aggressive bone tumor such as Ewing's sarcoma. Imaging findings are presented and discussed. Our case indicates that MHP should be considered in the differential diagnosis of skull-base tumors despite the fact that MHP is extremely rare in childhood.
