[Abdominal aortic aneurysm and Bourneville's tuberous sclerosis].

The authors report on a case of tuberous sclerosis diagnosed in the neonatal period on the basis of intracardiac tumor, rib anomalies and cerebral calcifications. At 4.5 months of age the infant presented acute abdominal pains which led to the discovery (ultrasound identification confirmed by CT scan) of a giant ectasia of the whole abdominal aorta. The infant died 2 days later from the rupture of this aortic aneurysm.
