Isolated spontaneous dissection of visceral artery without associated aortic dissection is rare, although more cases have recently been reported because of the rapid advancement of diagnostic imaging techniques. Complications are ischemia, aneurysm formation and rupture. We present a case with rupture of isolated dissection of the celiac artery with pseudoaneurysm formation. The patient was a 54-year-old male smoker without any recorded medical history, who underwent sonography, multidetector CT angiography (CTA), contrast-enhanced MR angiography (CE-MRA), and DSA. The final diagnosis was rupture of isolated celiac artery dissection with the formation of pseudoaneurysm. Resection of the pseudoaneurysm was performed. The postoperative course was uneventful except for biliary fistula resulting from ischemia and necrosis of compressed common bile duct. The patient was in good condition in follow-up. This case indicated noninvasive CTA and MRA had an important role in the detection and follow-up of celiac artery dissection and its complications.
