From: Giant right coronary artery aneurysm mimicking a right intra-ventricular mass: a case report
(A) TEE revealed a 3.5 × 2.7 cm cystic mass (white arrows) with hyperechoic external capsule locating below the annulus of posterior tricuspid leaflet; (B, C) Coronary CTA revealed an irregular mass (white arrows) with internal contrast enhancement and thick external capsule locating below the tricuspid valve. A feeding vessel (black arrow) originating from RCA (white arrow head) was identified; (D) 3D reconstruction of coronary arteries confirmed that the mass was supplied by RCA and left coronary artery disease was eliminated; (E) After detaching the posterior leaflet from the tricuspid annulus, the mass (white arrows) was detected with collagen-like degenerative fibrous coating; (F) The RCA aneurysm was resected and the posterior leaflet was repaired and reattached to the annulus by continuous suture with 5–0 prolene.
