Right coronary artery aneurysm with fistula to left ventricle: multislice CT appearance.
A 34-year-old male presented with prior radiographic evidence of enlargement of the right side of the heart. ECG-gated enhanced multislice CT was performed. Axial source images revealed a diffuse, hugely enlarged right coronary artery (RCA) aneurysm. The distal portion of the RCA flowed directly into the left ventricle (LV), suggesting an RCA to LV fistula. 3D volume rendered images clearly revealed a huge, enlarged RCA aneurysm from the proximal, mid, and distal portions of the RCA. The distal portion of the RCA aneurysm disappeared abruptly without showing distal branching, also suggesting an RCA to LV fistula.
