case_images: The chest radiograph showed a grossly enlarged cardiac shadow, an enlarged pulmonary trunk and a small-calibre ascending aorta. No rib notching was noted

case_images: Chest radiography (Fig. 1) showed gross cardiomegaly and a dilated pulmonary trunk.
case_images: Computed tomography images showing: (A) and (B) a small-calibre ascending aorta with the aortic arch interrupted after the origin of the left common carotid artery (arrow in A) and separated from the left subclavian artery (arrowhead in B) and descending aorta (curved arrow in B). The pulmonary trunk (* in A) was markedly dilated. (C) A ventricular septal defect could also be visualized (arrow)

case_images: CT (Fig. 2) revealed discontinuity between the ascending aorta and descending aorta, with the descending aorta and left subclavian artery supplied by the grossly enlarged pulmonary trunk (measuring 6 cm in diameter) via a patent ductus arteriosus (PDA).
case_images: Magnetic resonance imaging (MRI). (A) and (B) Contrast-enhanced magnetic resonance angiography (MRA) with subtraction showing aortic interruption and an enlarged pulmonary artery supplying the left subclavian artery and descending aorta via a patent ductus arteriosus. No significant collateral flow was present. (C) T2W TRUFI sagittal image showing a patent ductus arteriosus (straight arrow) supplying the left subclavian artery (arrowhead) and descending aorta (curved arrow). (D) SSFP cine image showing a bicuspid aortic valve (arrow). (E) Evidence of a ventricular septal defect (arrow) and right ventricular hypertrophy (curved arrow) was also seen
