Abstract
In a young woman with Takayasu's arteritis, standard roentgenographic studies suggested a diagnosis of Crohn's ileocolitis. Mesenteric angiography was performed and revealed specific abnormalities diagnostic of Crohn's disease, namely, the zoning sign in the cecum with a hypervascular inner layer and a hypovascular outer layer, and paraintestinal inflammatory neovasculature adjacent to the ascending colon. In addition, several helpful but nonspecific findings were demonstrated, and these features are reviewed. This patient represents another example of large vessel lesions associated with inflammatory bowel disease.
