Abstract

Taste disorder is not rare in patients with acute stroke is not usually evaluated. There is also controversy about central gustatory pathways. We report one case of ipsilateral hemiaguesia induced by a right middle cerebral artery infarction. A right-handed 70-year-old woman presented with headache. She had a history of hypertension and diabetes mellitus. The systemic examination revealed no abnormalities. Neurologic examination revealed left side hemispatial neglect and right side hemiageusia. Brain MRI showed high signal intensity in the right middle cerebral artery territory including the temporal lobe and parietal lobe with sparing insular cortex on T2 and diffusion weighted image (DWI). This case is suggestive of the existence of an uncrossed ascending gustatory pathway, explaining the ipsilateral hemiageusia above the midbrain lesion. KeyWords:Hemiaguesia, Dysgeusia, Taste disorder
