Thoracoabdominal aorta coarctation with bilateral renal artery involvement: diagnosis with multidetector CT angiography (MDCTA).

Atypical coarctation of the descending thoracic and abdominal aorta is a very uncommon vascular disease. Congenital, acquired, inflammatory, and infectious etiologies have been proposed. Patients typically presents with uncontrolled secondary hypertension in the upper half of the body or hypotension in the lower extremities in the first three decades of their lives. We report the case of a 20-year-old man with severe hypertension. Diffuse coarctation of thoracoabdominal aorta associated with bilateral renal artery stenosis was demonstrated clearly by multidetector CT angiography. This is the first case of atypical aortic coarctation diagnosed by MDCTA.
