Abstract

|
We report a patient who developed left side hemineglect after a right pontine ischemic lesion. An 82-year-old woman without histories of stroke and dementia was admitted because of left side weakness and dysarthria. On neurological examination, she had no visual field defects, but she was unable to detect stimuli presented in the left side of space. She also had the extinction to simultaneous presentation of visual stimuli. Her brain MRI showed an infarct in the right pons. The hemineglect symptom had improved by two weeks after the onset. We propose that her hemineglect was cause by the right pontine lesion. The underlying mechanisms of the hemineglect associated with pontine lesion are not clear, but we hypothesize that it may be due to diaschisis in the left cerebellum or right frontal or parietal lobe, or due to disruption of noradrenergic pathway projecting to association cortices.
