Multidetector computed tomography of congenital anomalies of the thoracic aorta.

Author information

Division of Thoracic Radiology, The University of Texas Health Science Center, San Antonio, TX, USA.


Congenital abnormalities may affect any segment of the thoracic aorta. Their clinical presentation is quite variable, and some may require prompt and precise diagnosis to avoid complications. Associated cardiovascular comorbidities are common, and their presence and type may significantly affect prognosis, management, and patient outcome. Nowadays, state-of-the-art multidetector computed tomography has replaced invasive angiography in the evaluation of patients with suspected aortic disease. With the advent of this technology that allows diagnostic scans even in small infants and newborns, radiologists must be familiar with anatomy and pathophysiology of these uncommon diseases. The embryology, morphology, and imaging findings of these anomalies, divided according to their anatomic location, are reviewed.
