Neurofibroma of the auriculotemporal nerve.

Despite the extensive branching of the trigeminal nerve, solitary neurofibromas along its branches are a rare finding. We report our management of a neurofibroma of the right auriculotemporal nerve in a 46-year-old women. A chain of small nodules palpable in the right postauricular region was associated with increasing pain radiating into the postauricular and temporoparietal regions of her head. Magnetic resonance imaging and computed tomography showed several small ovoid lesions extending from the postauricular region to the infratemporal fossa. The lesions were removed surgically. The facial nerve adhered to the dorsal side of the largest nodule, but this could be removed without sequelae. The auriculotemporal nerve was identified as the nerve of origin and was removed together with the lesions. Histopathological examination was consistent with a neurofibroma with early plexiform cell formations. Clinical findings are discussed.
