Undifferentiated Trigeminal Autonomic Cephalalgia in Lateral Medullary Infarction

Abstract

A 58-year-old man presented with severe retro-orbital headache with autonomic symptoms, vertigo, dysarthria, dysphagia, hypaesthesia, dysmetria, and ataxia. Brain magnetic resonance imaging demonstrated lateral medullary infarction with no evidence of vertebral artery dissection. Undifferentiated trigeminal autonomic cephalalgia may occur in the setting of lateral medullary infarction, probably secondary to trigeminal system dysfunction.
