A woman had a left superior cerebellar artery infarct associated with reduced hexamethyl-propileneamine oxime uptake on SPECT scan of the basal ganglia and frontoparietal areas of the opposite hemisphere performed poorly in some neuropsychological tests indicating right hemisphere dysfunction. There was a lengthening of reaction and movement times with the hand ipsilateral to the lesion. These deficits were temporary. A unilateral cerebellar lesion can produce neuropsychological deficits, possibly because of hypoperfusion in contralateral frontoparietal regions, but spontaneous neuropsychological remissions may occur.

Résumé:

Résumé:

Fonction neuropsychologique avec une lésion cérébelleuse unilatérale. Il s’agit d’une patiente ayant eu un accident cérébro-vasculaire suite à une thrombose de l’artère cérébelleuse supérieure et qui a présenté une diaschisis cerebello-corticale à la scintitomographie (SPECT) avec hexamethylpropileneamine oxime (HMPAO). L’évaluation neuropsychologique a été suggestive d’une dysfonction frontopariétale droite, la même localisation que celle de 1’hypoperfusion constatée au SPECT. Une lésion cérébelleuse unilatérale peut déterminer des déficits suggestifs d’une dysfonction neuropsychologique frontopariétale contralatérale en présence d’un scan normal.
