[Aortic abdominal aneurysm rupture leading to a massive gastrointestinal bleeding in a patient with Behçet's disease].

INTRODUCTION

Arterial involvement in Behçet's disease is rare, present in 2-8% of cases. Aortic aneurysms represent the most frequent arterial lesions encountered in this disease and are associated with high mortality.

CASE REPORT

We report the exceptional observation of an abdominal aortic aneurysm ruptured to the duodenum, responsible of a massive gastro intestinal bleeding in a patient with Behçet's disease requiring an emergent surgical intervention. The outcome was favorable.

DISCUSSION

The clinical presentation of abdominal aortic aneurysms in Behçet's disease is often atypical leading to an important diagnosis delay and favours the rupture of the aneurysm.
