An Autopsy Case of Abdominal Aortic Aneurysm in a Pediatric Decedent With Tuberous Sclerosis Complex.

Abstract: Vascular involvement in tuberous sclerosis complex (TSC) is uncommon and even more so in pediatric patients. When asymptomatic, these vascular abnormalities carry increased risk of rupture with increased morbidity and mortality. Here, we describe a case of a ruptured unrecognized abdominal aortic aneurysm in an 11-month-old patient with a history of TSC. The abdominal aortic aneurysm was discovered at autopsy and highlights the rarity of abdominal aortic aneurysm in pediatric patients diagnosed with TSC and the importance of screening for associated aneurysmal disease in the pediatric population with TSC. Furthermore, the extensive retroperitoneal hemorrhage seen in this case also highlights a rare but potential mimic of abuse in the pediatric population.
