[Case of gustatory disturbance caused by pontine infarction].
We reported a 72-year-old man presented with gustatory disturbance. He lost bitter, salty, sour and sweet sensation on the left half of the tongue. No other neurologic signs were observed. Brain MRI showed the cerebral infarction in the left middle cerebellar peduncle. The lesion was suspected of affecting the gustatory tract running from the nucleus solitalius to the pontine taste area in the upper pons. The gustatory tract is generally recognized to be located medially from the medial lemniscus and the reticular formation. Our case suggests that the tract would be located laterally from the medial lemniscus and the reticular formation.
