17-year-old boy with unruptured right sinus of Valsalva aneurysm, contrast-enhanced CT (a) Axial image reveals a large outpouching (An) arising from the right coronary sinus with eccentric thrombus (*) and peripheral thin calcification and normal LCS and NCS. (b) Oblique sagittal image shows partially thrombosed aneurysm (arrow) with normal aortic root (Ao). (c) Oblique coronal image shows aneurysm with dilated pulmonary artery (arrow) with normal ascending aorta and aortic annulus. Ao = Aortic root, LCS = Left coronary sinus, LV = Left ventricle, MPA = Main pulmonary artery, NCS = Non-coronary sinus, RA = Right atrium, RV = Right ventricle.

The lumen of the aneurysm was partially opacified by the contrast, with a large eccentric non-enhancing thrombus noted along the dome of the aneurysmal sac [Figure 1]. The left coronary artery appeared normal in course and caliber [Figure 1].
17-year-old boy with unruptured right sinus of Valsalva aneurysm, contrast-enhanced CT (a) Coronal image shows aneurysm (An) compressing the RVOT (arrow) with dilatation of RA and RV. (b) Axial image shows the aneurysm extending along right atrio-ventricular groove (arrow). (c) Oblique coronal image shows dilated right cardiac chambers, intrahepatic IVC, and hepatic veins (arrow). An = Aneurysm, LA = Left atrium, LV = Left ventricle, RA = Right atrium, RV = Right ventricle, RVOT = Right ventricular outflow tract, IVC = Inferior vena cava.

There was resultant gross asymmetric dilatation of the right atrium and ventricle and associated dilatation of the inferior vena cava and hepatic veins suggestive of congestive changes [Figure 2].
