Arterial hypoplasia in neurofibromatosis 1

We describe the case of a 14-year-old boy with neurofibromatosis 1, associated with multiple abnormalities on the right side, namely hypoplasia of both limbs with long bone malformations, hypoplasia of the iliac, femoral and popliteal arteries without hemodynamic abnormalities, and stenosis of the renal artery which, later, evolved into hypertension. This case, similarly to another one reported, underlines the need to evaluate the vessels in patients with neurofibromatosis 1 and limb asymmetry.
