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.
