Abstract
|
|
|
Trigeminal sensory neuropathy can represent chronic pain, anesthesia or paresthesia symptoms that affects the trigeminal
nerve, which carries sensation from the face to brain. Because the clinical findings do not permit accurate lesion localization, brain MRI must be used to visualize the entire course of the fifth cranial nerve. A 57-years-old man presented with subacute sensory change of V2 and V3 area of left face for 2 weeks. He had complained of progressive hypoesthesia and pain of left face. The facial NCS and blink reflex study revealed left trigeminal neuropathy. Brain MRI showed linear enhancement of pontine segment in left trigeminal nerve. After steroid treatment, there are improvementsof symptoms and MRI findings.
