An Eighty four year old lady presented with subarachnoid haemorrhage (Hunt & Hess Grade II; Fisher Grade 3). Angiogram (Fig. 1.1) revealed a small basilar top aneurysm with a broad neck. The aneurysm was lobulated, and the neck was more towards the origin of left PCA. Both vertebral arteries were extremely tortuous with loops just beyond the origin and at the V2 segments.
