Pure sensory stroke caused by a small cortical infarct in the middle cerebral artery territory.

Abstract

A patient with the sudden onset of a pure sensory deficit involving cortical modalities in his left hand and foot is described. CT scan suggested the lesion responsible for the deficit was a small cortical infarct in the middle cerebral artery territory, involving the middle part of the post-central gyrus and interrupting thalamo-cortical pathways in the corona radiata.
