title: Computed tomography findings in ruptured arteriovenous malformations of the corpus callosum.
abstract: Computed tomography (CT) is of proven value in the evaluation and localization of intracranial hemorrhage. The recognition of various patterns of subarachnoid, intracerebral, and intraventricular hemorrhage is necessary in order to provide accurate localization and to predict probable etiology of the bleed. We present three cases with angiographically proven ruptured arteriovenous malformations involving the midline of the corpus callosum. The clinical presentation and CT findings are discussed. We believe this represents a distinctive pattern of hemorrhage specific for this entity.
