Cardiac Computed Tomography Pictorial Equivalent of Angiographic Gooseneck Sign in a Case of Atrioventricular Septal Defect with Cor Triatriatum Sinister

In the literature, multiple radiological signs of clinically important congenital cardiovascular abnormalities have been described which are named as per the object they resemble. These signs are very useful in learning. The Gooseneck sign is a sign seen in left ventricle catheter angiography in case of an atrioventricular septal defect. This sign has not been demonstrated on a cardiac computed tomography (CT) so far, to the best of our knowledge. We present a case showing cardiac CT pictorial equivalent of angiographic Gooseneck sign.
