Renal artery aneurysms and pseudoaneurysms are an uncommon clinical problem with a low incidence rate. They are abnormal dilatations of the vessel lumen with some different natures. However, the rupture of an aneurysm and pseudoaneurysm is the most dreaded complication because it causes death of the patient. There are many causes of renal artery aneurysm and pseudoaneurysm, including Behçet's disease; however, renal involvement in Behçet's disease is less frequent. We report a case of renal artery pseudoaneurysm induced by Behçet's disease and treated successfully with coil embolization. A 56-year-old woman with Behçet's disease presented with an incidental left renal artery pseudoaneurysm measuring 18 mm. We successfully performed endovascular treatment with coil embolization instead of surgical treatment.
