[33-year old patient with thoraco-abdominal pain and differences of blood pressure]

We report on a 33-year-old women with ulcerative colitis, who presented with inspiratory thoracic pain due to perimyocarditis. Furthermore, postprandial abdominal pain associated with diarrhea and different blood pressure values on both arms were recorded. Computed tomography revealed embolism of the pulmonal arteries and angiography demonstrated stenoses of the subclavian and renal arteries and the celiac trunc suggesting the diagnosis of Takayasu's arteritis. A coronary or infectious etiology could be excluded. Since a coincidence of Takayasu's arteritis and ulcerative colitis has been reported in the literature, abdominal pain and diarrhea can either be explained by the inflammatory bowel disease or by chronic ischemia due to intestinal vasculitis. Differential diagnosis will be facilitated by the future course of the disease.
