Cerebral angiogram. Lateral (A) and anteroposterior (B) catheter angiograms, the left vertebral artery injection showing the right superior cerebellar artery aneurysm. The aneurysm was repaired by endovascular coiling, leaving minimal or no residual neck visible on the lateral (C) and anteroposterior (D) views after treatment. Gadolinium-enhanced magnetic resonance angiography seven days later shows a small residual neck (E, F). At the last follow-up 51 months later, there has been some growth of the residual neck on magnetic resonance angiography (G, H).
