Although peripheral vascular thrombic events are recognized as a serious extra-intestinal complication of inflammatory bowel disease, the occurrence of cerebral vascular events in association with acute exacerbations of this group of diseases is rare. In this article, relevant literature is reviewed and three children, 5, 12, and 13 years of age, who presented with clinical and magnetic resonance imaging evidence of an acute cerebrovascular event in association with an acute exacerbation of their inflammatory bowel disease are described. Except for the presence of anemia, hematologic and coagulation studies were unremarkable, and a search for evidence of a systemic vasculitis proved negative.
