A rare etiology of right lower back pain in a young man: contained rupture of the common iliac artery aneurysm.

Abstract

Relatively rare aneurysms of the common iliac artery are abnormal dilatations of the vessel, which can be complicated by a rupture that, in rarer cases, may be contained by surrounding structures. Imaging, particularly CT angiography, plays a key role in diagnosis. We report a case of a contained rupture of the common iliac artery aneurysms responsible for hydronephrosis, obstruction of the common iliac vein, and lysis of the adjacent vertebra.
