(A, B) Reformatted computed tomography (CT) coronary angiogram images showing an anomalous left coronary artery (red arrows) arising from the pulmonary artery with a diffusely dilated and tortuous course of the main left coronary artery and its branches, along with multiple collaterals. Note the origin of the right coronary artery (blue arrows) from the right coronary cusp with a dilated and tortuous course. The right coronary artery is noted supplying the left coronary artery via multiple collaterals. (C) Oblique coronal reformatted image of the CT coronary angiogram showing the origin of the RCA and LCA with their courses. LCA, left coronary artery; RCA, right coronary artery.
