title: Aneurysm re-rupture during computed tomography angiography.
abstract: Re-rupture of cerebral aneurysms during conventional angiography, demonstrated by contrast leakage into the extravascular space, is well known and well documented. However, the occurrence of this complication during computed tomography (CT) angiographic examinations has rarely been published despite its extensive use. We present the clinical and radiological features of a rebleeding event during a CT angiographic study. No hemodynamic or contrast-related factors can be evoked predisposing to he occurrence of this complication during this imaging technique. This, along with the short study time, may explain the rarity of this coincidence.
