OBJECTIVES: To describe a patient with a demyelinating brainstem lesion who developed right-sided trigeminal neuralgia triggered by auditory stimuli and to discuss the pathophysiological mechanisms underlying this unusual phenomenon.
DESIGN: Case report.
SETTING: Referral center.
PATIENT: A 27-year-old man who presented with clinical signs of a brainstem lesion developed right-sided trigeminal neuralgia triggered by auditory stimuli to the right ear. Magnetic resonance imaging and electrophysiological studies demonstrated a demyelinating lesion in the pons affecting the right lateral lemniscus and the right trigeminal pathway. This phenomenon completely subsided within 4 days. After a relapse, the diagnosis of clinically definite multiple sclerosis was made.
CONCLUSION: Lateral spread of impulse activity within the demyelinating pontine lesion is the likely explanation for the unusual phenomenon of trigeminal neuralgia triggered by auditory stimuli.
