Extracorporeal shock wave lithotripsy (ESWL) can lead to rare but severe arterial complications. The causal relationship of ESWL with arterial pseudoaneurysm formation in a patient with Behçet disease is discussed. A 35-year-old man presented with acute recrudescence of right flank pain caused by ureteral lithiasis immediately after having undergone a last session of ESWL. Abdominal examination revealed a painful pulsatile mass in the right iliac region. Contrast-enhanced computed tomography identified a pseudoaneurysm of the right external iliac artery in a patient with a medical history of Behçet disease. The pseudoaneurysm was treated endovascularly, including the use of a covered stent with intensive immunosuppressive therapy. We obtained successful exclusion of the pseudoaneurysm. This case highlights that arterial pseudoaneurysm may occur after ESWL in patients with Behçet disease. Strict follow-up after ESWL sessions is necessary.
