There is a 20*25 mm signal void round lesion anterior to the midbrain in midline position with mild pressure effect, in keeping with a basilar tip aneurysm.
No further intracranial aneurysm or vascular malformation identified.
Case Discussion
Basilar artery aneurysms are less common than anterior circulation aneurysms and rupture less frequently, but their critical location necessitates careful evaluation.
