title: Tegmental pontine hemorrhage with pure trigeminal motor impairment.
abstract: We report a patient with a right dorsolateral pontine syndrome including right masticatory weakness without facial hypesthesia. Brain computed tomography showed a right dorsolateral pontine hemorrhage. Blink reflex study indicated preservation of spinal tracts and sensory nuclei of the trigeminal nerve. Right masseter electromyography revealed denervation. This patient provides a good correlation between clinical, radiological and electrophysiological findings and nuclear organisation of the trigeminal nerve.
