Abstract

Choroid plexus papillomas are highly vascular tumors, and such tumors causing subarachnoid hemorrhage have been reported in literature. Similarly, few articles have reported atypical fourth ventricular choroid plexus tumors in adults. However, such an atypical tumor presenting with grossly hemorrhagic transformation without any acute symptoms could not be found in the literature.
