CTICasesRight Ventricular Apical Diverticulum
Imaging findings
Cardiac MRI shows an out-pouching at the apex of the right ventricle that beats synchronously with the myocardium, representing a congenital diverticulum rather than a hemangioma or pseudoaneurysm.
Key takeaways
Right ventricular diverticula are rare congenital anomalies. Unlike pseudoaneurysms, which have a narrow neck and do not contract, congenital diverticula contain all myocardial layers and display synchronous contractility, carrying a benign prognosis.
