Computed tomography coronary angiography (CTCA) showed that there was no lumen stenosis in the left anterior descending artery or left circumflex artery (Figures 1A,B).
Computed tomography coronary angiography shows the WCA in the right coronary artery. Volume rendering reconstruction (A), Maximum intensity projection (B) and Curved multiplanar reconstruction (C) revealed multiple twisting channels in the proximal segment of the right coronary artery and merged again into a normal conduit. Small patchy calcification was observed in the structure. (D) Consecutive cross-sectional images at the lesion site showed twisting and multiple small channels.

Patchy calcification was found in the structure (Figures 2A-D).
Coronary angiographic findings of the patient. (A) and (B) showed the braid-like change at the proximal portion of RCA. There was a normal blood flow in the distal segment of the anomaly. (C) and (D) revealed the normal left anterior descending artery and left circumflex artery.

In order to further clarify the possible etiology, the patient underwent coronary angiography (CAG), which demonstrated the same imaging findings as the CTCA (Figures 3A-D).
