Intracranial Hemangiopericytoma in a Child: A Case Report with Magnetic Resonance Spectroscopy Findings.

Hemangiopericytoma is a hypervascular soft tissue sarcoma with a predilection for the extremities. It has two clinical types according to the age of presentation: Infantile hemangiopericytoma ( < 1 years) and adult type hemangiopericytoma ( > 1 years). The intracranial location is very rare and accounts for only 0.4-1% of all primary brain tumors, with only 10% detected in the pediatric age group. The differential diagnosis of this rare tumor from other extra-axial masses plays an important role in proper treatment planning. There are few case reports in adult patients indicating that magnetic resonance spectroscopy (MRS) can play a role in the differential diagnosis. Here, we present imaging findings of this rare tumor, including MRS at 3.0T of an intracranial hemangiopericytoma in a 4.5 year old boy.
