A patient with left parietal lobe infarction presenting with bilateral limb-kinetic apraxia, bilateral agraphaesthesia, and bilateral astereognosis

We report a 77-year-old male who presented with acute cerebral infarction in the left posterior central gyrus and left superior parietal lobule, and left supramarginal gyrus and its subcortical white matter, resulting in bilateral agraphaesthesia, bilateral astereognosis, and bilateral limb-kinetic apraxia. It is generally known that limb-kinetic apraxia and sensory dysfunction appear on the contralateral side of the lesion, but in this case, limb-kinetic apraxia and some sensory dysfunction appeared on the ipsilateral upper limb as well as the lesion. This suggests that, similar to Liepmann's theory, hemispheric dominance and interhemispheric connectivity are involved.
