Rare complications of neurofibromatosis 1 diagnosed incidentally in two children

Abstract

Neurofibromatosis 1 (NF1) is an autosomal-dominant disorder with various clinical expressivity and complications. Arterial hypertension may be present in patients with NF1 and is secondary to vasculopathy or pheochromocytoma. We herein describe two children (17 and 4 years old) diagnosed late with NF1 after severe arterial hypertension had been discovered due to pheochromocytoma and middle aortic syndrome. Routine measurement of arterial pressure is mandatory in children with NF1, in order to diagnose the complications of this disease.
