intracranial hemangiopericytomas (hpc) are rare vascular tumors. they account for 0.4% of primary central nervous system tumors. hpc is more commonly located supratentorially and tends to occur in a younger age group, with average age at presentation of 38–42 years. the tumor was found throughout the entire cns, usually superficially and closely related to the meninges. moreover, they have a st...
