Trigeminal sensory neuropathy is a clinical diagnosis in which the main feature is facial numbness limited to the territory of one or more sensory branches of the trigeminal nerve. We report a 44-year-old woman who presented with numbness and neuralgic pain at her left face. Brief electric shock-like pain lasted about a few seconds and occurred at least 5 times a day. The pain was triggered by chewing and facial washing. On neurologic examination, light touch sensation was decreased in the V2 and V3 dermatomes of the left face including the tongue, lips, and gum. While pinprick and temperature sensation were preserved. Brain magnetic resonance imaging (MRI) showed a left pontine infarction. Presumably, an ischemic injury may have led to increased neuronal activity in the trigeminothalamic tract. We suggest the paroxysmal facial pain is possible as an episodic activation of the trigeminal neurons by triggering. (Korean Journal of Stroke 2007;9:91-93)
