  FIGURE 1. Contrast‐enhanced CT angiographic images of the RCA, demonstrating three regions of aneurysmal dilatation. Proximal RCA with aneurysmal dilatation in the perpendicular short‐axis view (A) and in the long‐axis view (B), in total measuring 4.3 × 2.9 × 9.8 mm. The short axis (C) and the long axis (D) of the aneurysmal dilatation of the RCA at the origin of the acute marginal artery, measuring 6.4 × 4.8 × 10 mm. Likewise, in the short axis (E) and the long axis (F), it is depicted at the bifurcation of the PDA and the atrioventricular nodal artery, measuring 4.5 × 3.2 × 11 mm

  FIGURE 2. Contrast‐enhanced CT angiographic images of the LMCA and branches. Image A demonstrates a prominent LAD with irregular margins without aneurysmal dilatation of the segment between the bifurcation with the LCX and the first septal branch. Image B in long axis ({) and image C in short axis (○) depict aneurysmal dilatation of the bifurcation of the LAD and LCX, measuring 4.3 × 4.0 × 5.1 mm
