Hypertension in patients with neurofibromatosis is often essential, but some patients also present with RVHT (see the image below). These patients have a pattern of RAS similar to that observed in FMD. However, involvement of the intrarenal arteries and arterioles may also exist. Neurofibromatosis usually involves the renal arteries of both kidneys. [9]
