Abdominal aortic aneurysm in a neonate.

This is the second reported case of abdominal aortic aneurysm in neonates to be presented in the English language literature. The first case was reported by Howorth in 1967. In addition to the presence of abdominal aortic aneurysm, this neonate has nesidioblastosis and sequestration of the lungs. The combination of these three rare anomalies in one infant is fascinating and has not been reported.
