Case Discussion

The pattern of subarachnoid hemorrhage is patient suggests that this is a centrally located anterior circulation aneurysm, which CTA confirms. The patient proceeded to angio-embolization with coiling resulting in a good angiographic result. 

ACOM aneurysms most often arise from the junction of ACOM and the dominant A1 segment.
