Patient Data

Gender: Male
CT

Intraparenchymal hemorrhage with lower attenuating "filling defect". Hemorrhage extends into ventricular system as well as into subarachnoid space. Minor hydrocephalus.

Case Discussion

Initial CT demonstrates intraparenchymal, subarachnoid and intraventricular blood, with hydrocephalus

Within the hematoma, a rounded lower density area is present which is suspicious for a large aneurysm. 

CTA (not shown) confirmed the presence of an aneurysm which was further imaged with angiography. 

The aneurysm was filled with numerous coils.
