Subtotally thrombosed large proximal RCA fistula with right atrium together with anomalous origin of RCA in 21-year-old male with palpitations. Semitransparent 3D volume rendered image (a) showing anomalous origin of ectatic RCA arising from left coronary cusp with faintly opacified coronary artery fistula draining into right atrium due to subtotal thrombosis. Axial oblique MIP image (b) at the level of aortic root shows the anomalous origin of RCA and its malignant interarterial course with subtotal thrombosis of proximal RCA fistula. Axial oblique MIP image (c) at higher level reveals the remaining length of the subtotally thrombosed proximal RCA coronary fistula with its draining site into right atrium with possible extension of thrombus tail inside right atrium
