Color duplex ultrasonography in detecting renal artery abnormalities in a patient with neurofibromatosis 1: a case report

Neurofibromatosis type 1 (NF1) is a rare disease; it involves not only the nervous system, but also both large and small arteries. Common vascular complications of NF1 include arterial stenosis, aneurysms, and arteriovenous fistulas involving the abdominal aorta and its branches. A coexisting left renal artery stenosis and aneurysm in a pediatric patient with NF1 was initially detected by color duplex ultrasonography in our institute.
