A Rare Case of Pediatric Ventricular Pseudoaneurysm as a Sequelae of Ascending Aortic Dissection

Background: Aortic dissection is a critical cardiovascular condition characterized by the separation of the aortic wall layers, leading to the formation of a false lumen that can compromise blood flow and result in severe complications. While it is predominantly observed in adults, pediatric cases, although rare, can occur and may lead to unusual sequelae such as ventricular pseudoaneurysms. Case presentation: A 9 - year - old boy with complaints of breathlessness for a month and vague chronic chest pain. ECG and ECHO were performed which showed chronic ischemic changes and inferior wall aneurysm. On CT examination, the topogram revealed a well- defined elliptical diffuse eggshell calcification involving most of the left cardiac silhouette. CT thoracic angiogram showed a well - defined elliptical outpouching arising from the inferior wall of the left ventricle with a thin rim of wall calcification. A peripheral wedge - shaped non - enhancing area in the lower pole of the spleen was seen, suggesting a splenic infarct. Conclusion: This case report illustrates a rare but significant sequela of ascending aortic dissection in a pediatric patient?a ventricular pseudoaneurysm. It serves as a reminder of the complexities involved in diagnosing and managing aortic dissections in younger populations.
