We report a case of fatal subarachnoid hemorrhage from nontraumatic rupture of an aneurysm at the basilar terminus in which both computed tomography angiography and conventional angiography showed evidence of active bleeding. The time period from initial ictus to CT angiography was 30-50 minutes and to conventional angiography was 120-140 minutes. This case illustrates that aneurysmal bleeding is not necessarily as brief as a few seconds and can last up to 30 to 50 minutes and perhaps longer. Continued bleeding from an intracranial aneurysm is a rare event that can be recognized using computed tomography angiography and likely indicates a poor prognosis.
