Hemangiopericytoma Arose From the Site of Meningioma Resection.

Intracranial hemangiopericytoma (HPC) is a rare tumor and accounts for 0.4% of all primary central nervous system tumors. However, it has aggressive behavior in growth and infiltration. The importance of diagnosis and treatment between HPC and meningioma cannot be overemphasized. It is rare that HPC arises from the site of benign meningioma resection. And it would be benefitted to take HPC into account when coming across a patient with meningioma "recurrence." (C) 2017 by Mutaz B. Habal, MD.
