Ehlers-Danlos syndrome mimicking mesenteric vasculitis: therapy, then diagnosis

The etiology of acute intraabdominal bleeding is often unclear at the time emergent arteriography is performed. During localization and embolization, the arteriogram may suggest the diagnosis of vasculitis. However, controlling the bleeding remains the priority. Connective tissue diseases such as Ehlers-Danlos syndrome (EDS) may also cause bleeding and mimic vasculitis and must be included in the differential diagnosis. We present such a case in which the initial findings were misleading.
