title: Active hemorrhage of intracranial aneurysms: diagnosis by CT angiography.
abstract: Two cases of active hemorrhage from an intracranial aneurysm demonstrated by CT angiography are presented. In each case, extraluminal opacified blood was seen entering a recent hemorrhage surrounding the aneurysm, simulating a vascular structure. This is a potential pitfall in the interpretation of CT angiograms in patients with recent subarachnoid hemorrhage.
