CTICasesCongenital Right Ventricular Diverticulum
Imaging findings
CT abdomen and chest show an incidental, small, well-defined outpouching arising from the right ventricular (RV) apex, in continuity with the RV lumen, without surrounding mass effect or pericardial effusion.
Key takeaways
Congenital right ventricular diverticula are rare, benign cardiac anomalies characterized by a localized outpouching containing all myocardial layers. They are typically incidental findings and must be distinguished from acquired pseudoaneurysms (which lack myocardial layers and occur post-infarct or trauma) and pericardial hemangiomas.
