The association between abdominal aortic aneurysm and tuberous sclerosis is rare. We present 3-year-old girl with a pulsatile abdominal mass in the pediatrician´s medical review. An abdominal evaluation showed a 6cm infrarenal abdominal aortic aneurysm. The patient underwent open repair with a 14-mm Dacron tube graft. The histological examination revealed connective tissue proliferation, fibrosis, and calcification of the aortic wall. Frequent follow-ups with ultrasounds showed no alterations. Due to the high risk of rupture, early surgical repair is the first-line therapy.Keywords: Tuberous sclerosis, abdominal aortic aneurysm, congenital heart disease (CHD), vascular disease, genetics
