ABSTRACT
A 10-year-old boy presented with a mass on the left side of his face for many years, left ear deafness, and limited vision in the left eye. Enhanced CT of the face and neck showed a multilobulated low attenuation mass in the left parotid space, with nodularity and involvement of branches of the left facial nerve. There was a mass in the left orbital apex that extended into the left cavernous sinus, exopthalmos of the left eye, and erosion of the medial portion of the greater wing of the left sphenoid. Partial removal of the mass in the left parotid space was performed. Histopathological examination revealed plexiform neurofibromas. CT and MR imaging findings in neurofibromatosis type 1 patients with craniofacial abnormalities are discussed.
