Neurofibroma is a benign lesion of unknown origin that may occur in the peripheral nerve, soft tissue, skin or bone. It occurs as a solitary lesion more commonly than as a multiple lesion or in neurofibromatosis (NF-1 or von Recklinghausen's disease).he lesion visible on plain film may be a neurofibroma that has worked into the bone by pressure erosion or it may be a non-ossifying fibroma that is associated with NF-1. On ultrasound, a neurofibroma is a well-defined hypoechoic mass. On CT scan, a neurofibroma is a hypodense, well-defined mass.
