Takayasu's Arteritis in Crohn's Disease

This report describes a patient with coexistent Grohn's colitis and Takayasu's arteritis involving the thoracic aorta, superior mesenteric artery, and left hepatic artery. Unlike most previously reported cases of this association, characteristic histopathology is demonstrated. This case is also unusual in that the Takayasu's arteritis presented as aneurysmal disease instead of occlusive disease. We believe that Takayasu's arteritis may represent another of the many extraintestinal manifestations of inflammatory bowel disease.
