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

Hemangiopericytoma (HPC) is an uncommon neoplasm arising from Zimmerman pericytes around capillaries and postcapillary venules. Most HPCs are located in the musculoskeletal system and the skin. Central nervous system HPCs are rare. 1 Meningeal HPCs (M‐HPCs) constitute < 2.5 % of all meningeal tumors and < 1 % of all intracranial tumors. 2-4
