Abdominal aortic aneurysm in a child with tuberous sclerosis.

Abdominal aortic aneurysm is rare in the pediatric population and even more uncommon in association with tuberous sclerosis. We have presented a unique case of a 3-year, 8-month-old girl who was successfully treated. She was admitted because of breakthrough seizures. A painless pulsatile abdominal mass on examination prompted an abdominal ultrasound scan, which identified a large saccular abdominal aortic aneurysm. Urgent replacement of the abdominal aorta with a 12-mm woven Dacron graft was undertaken. A postoperative ultrasound evaluation confirmed the successful repair. She was growing well when examined 7 months after surgery.
