Cardiac-MRI demonstration of the ligamentum arteriosum in a case of right aortic arch with aberrant left subclavian artery

Figure 3 Four sequential frFSE T2-weighted cardiac-gated axial images (A-D) and sequence (E). A-D: The ligamentum arteriosum from its proximal attachment on Kommerell’s diverticulum (KD) to its distal anchorage site on the superior aspect of the left pulmonary artery (LPA) origin; E: The complete course of the ligamentum arteriosum, which is appreciable anteriorly to the esophagus and trachea. Arrows indicate ligamentum arteriosum. VC: Vena cava; LBCV: Left brachio-cephalic vein; T: Trachea; E: Esophagus; LCA: Left common carotid artery; AA: Ascending aorta; DTA: Descending thoracic aorta; ALSC: Aberrant left subclavian artery.
