%X Cystic medial necrosis is a disorder of large arteries, particularly the thoracic aorta, characterized by an accumulation of a basophilic ground substance in the media with cyst-like lesions. A male in his late 20s was brought to our trauma bay after he met with a road traffic accident with a complaint of abdominal pain. Clinical examination revealed tenderness in the left lumbar region. The contrast-enhanced computerized tomography revealed an aneurysm of size 11×9.6×9.2 cm in the left lateral aspect of the abdominal aorta at the origin of the left renal artery. Intraoperatively, an aneurysm of size 10×10 cm from the juxta renal abdominal aorta was identified, and aortic rent was repaired with a polyester graft. The tissue was sent for histopathology, which showed complicated atherosclerosis with cystic medial degeneration and aneurysmal rupture of the abdominal aorta containing thrombus. The patient had an uneventful postoperative course and is doing well without any complaints at a two-year follow-up.
