Answer for BIR CoW 14 Mar 2021
Vertebral artery aneurysm
Findings
MR images reveal acute perimesencephalic haemorrhage with saccular aneurysm of the distal Left vertebral artery (V4 segment )suggestive of ruptured left vertebral artery aneurysm
Discussion
Intracranial vertebral artery aneurysms are relatively uncommon of all intracranial aneurysms. Vertebral artery aneurysms include VA-PICA aneurysms, Vertebrobasilar junction aneurysms, distal PICA aneurysms and distal vertebral artery aneurysms. Microsurgical clipping remains the mainstay of treatment, however ruptured posterior circulation aneurysms are technically difficult to expose and clip and their management and surgical outcomes are poorer compared to the anterior circulation aneurysms. Endovascular coil occlusion are preferred in patients with higher risk of surgery.
