CASE 60


A 56-year-old woman presented to her physician with the chief complaint of excruciating facial pain that comes and goes. Triggered by eating, drinking, and face washing, the pain occurs on her nose, upper cheek, upper lip, and upper teeth. The patient has lost weight since her last visit 10 months ago and is dehydrated. The physical examination was unremarkable and a magnetic resonance imaging (MRI) study of the head revealed demyelination of a cranial nerve. Based on these findings, the patient was diagnosed with cranial nerve neuralgia and was initially treated with carbamazepine, an oral anticonvulsant. When the patient developed tolerance to this medication, microvascular decompression surgery was performed.
