Figure 1: Computed tomography angiogram images. (a) Oblique axial section showing atretic tricuspid valve (tailed arrow) and hypoplastic right ventricle and enlarged atria. (b and e) Coronal section showing a large aneurysm along the course of collateral (blue dotted arrows) and branching to both lungs. Lots of tiny collaterals are seen in the left mediastinal hilum (open red arrow). (c and d): Volume rendered reconstruction with aneurysmal major aortopulmonary collateral in pink color seen arising from right subclavian artery (*) close to right vertebral artery origin. The left vertebral artery (white arrow) is having a direct origin from left-sided aortic arch and is hypoplastic compared with right one
