Giant renal artery pseudoaneurysm 18 months after blunt trauma

Renal artery pseudoaneurysms are uncommon vascular lesions that require a high degree of suspicion because they are usually difficult to diagnose.

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
