CTICasesPseudo-coarctation of the Aorta
Imaging findings
Frontal radiographs show a mediastinal mass displacing the trachea. Sagittal CT reconstructions demonstrate a characteristic "kink" in the aorta at the level of the ligamentum arteriosum, with the arch positioned higher than normal.
Key takeaways
Pseudo-coarctation is a congenital lesion often associated with a bicuspid aortic valve (seen in this patient). It is distinguished from true coarctation by the absence of a significant pressure gradient and the specific anatomical configuration of the high-riding arch.
