Thermally induced transient trigeminal sensory neuropathy: Imaging findings

We report the clinical and imaging features of a patient with transient par tial trigeminal sensory neuropathy thought to have been induced by thermal injury to the tongue. Abnormal thickening and enhancement of the mandibular division of the trigeminal nerve was revealed by MR imaging. The diagnosti c considerations for masslike enlargement of the trigeminal nerve should in clude transient/inflammatory processes, as well as more common and sinister conditions, such as tumor.
