title: MR angiographic demonstration of an intracranial aneurysm not seen on conventional angiography.
abstract: A patient with documented subarachnoid hemorrhage underwent conventional angiography, which was negative. MR angiography performed immediately after the conventional angiogram demonstrated a 4-mm anterior communicating artery aneurysm. This finding was confirmed 1 week later with repeat angiography, and the aneurysm was clipped surgically.
