case_images: 56-year-old male patient admitted with chest pain diagnosed with three coronary arteries originating separately from the right coronary sinus. Axial oblique maximum intensity projection image shows left anterior descending artery (short white arrow), right coronary artery (open arrow), and left circumflex artery (long white arrow) - three coronary arteries originating from the right coronary sinus.

case_images: 56-year-old male patient admitted with chest pain diagnosed with three coronary arteries originating separately from the right coronary sinus. (a) Volume-rendered three-dimensional image (VR-3D) shows the left anterior descending artery (LAD) originating from the right coronary sinus (short white arrow) and passing between the aorta (Ao) and the pulmonary artery (Pa) (open arrow: right coronary artery). (b) MDCT image shows LAD diagonal branch with myocardial bridging (arrowheads).
