Giant renal artery pseudoaneurysm 18 months after blunt trauma

Abstract

Renal artery pseudoaneurysms are uncommon vascular lesions that require a high degree of suspicion because they are usually difficult to diagnose. Posttraumatic renal artery pseudoaneurysms should be treated because spontaneous resolution is extremely unusual, and the risk of aneurysm rupture is high. We describe the case of a patient who presented with a pulsatile mass in the right upper quadrant and recurrent abdominal pain 18 months after blunt trauma. Arteriography and multislice computed tomography angiography revealed a pseudoaneurysm measuring 22 cm in the right renal artery. The patient was successfully treated with conventional open surgery.
