Abstract

Trigeminal sensory neuropathy is a clinical diagnosis in which the main feature is facial numbness limited to territory of one or more sensory branches of the trigeminal nerve. We describe a 46-year-old woman who presented with left facial numbness in the territories of maxillary nerve and mandibular nerve. MRI disclosed a lesion in left trigeminal nerve root entry zone. In Blink test stimulating infraorbital foramen, ipsilateral R1 was delayed compared with contralateral R1. Lesion in pons or medulla can present as trigeminal sensory neuropathy.
