Abstract
- Primary intracranial hemangiopericytoma is rare and resemble meningioma on imaging study. It shows meningeal attachment, and is usually isointense with gray matter on T1-weighted MR image with heterogeneous enhancement and prominent vascular flow voids on T2-weighted image. Cystic type of hemangiopericytoma is very rare and only 3 cases have been reported in the literature which arised in the middle fossa, cerebellum, and occipital area. Ventricular hemangiopericytomas were reported in 9 cases, and all of them were solid type. Authors experienced a peculiar case of cystic hemangiopericytoma in the 3rd ventricle and report it with review of the literature.
