Abstract

The generally accepted taste pathway in an animal projects ipsilaterally from the solitary nucleus. However, the path-way of gustatory fibers in the human brainstem has not been sufficiently clarified. A 57-year-old hypertensive man was admitted with sudden dizziness and hemiageusia. A neurological examination revealed also a diminution of taste on the left half of his tongue. A MRI showed a high signal intensity in the right lower pontine area. This case suggests that the unilateral lesion of the pons may lead to contralateral taste disturbances. Key Words : Ageusia, Facial nerve, Cerebral infarction
