Infra-renal abdominal aorta hypoplasia in a case of Down syndrome depicted by multidetector computed tomography angiography.

We report the case of a 3-day-old newborn with Down syndrome suffering from congenital infra-renal aortic hypoplasia. To our knowledge, this is the first report of a Down syndrome case with infra-renal abdominal aorta hypoplasia depicted by multidetector computed tomography angiography. In cases with no palpable pulsations in the lower extremities, multidetector computed tomography angiography is a fast and reliable diagnostic tool for the evaluation of distal aortic lesions.
