Preserving the ability to discriminate between left and right; A case study

Abstract

AbstractLeft‐right orientation, a function related to the parietal lobe, is important for many daily activities. Here, we describe a left‐handed patient with a right parietal brain tumour. During awake surgery, electric stimulation of the right inferior parietal lobe resulted in mistakes in his left‐right orientation. Postoperatively our patient had no problems in discriminating left right. This case report shows that monitoring of left‐right orientation during awake brain tumour surgery is feasible so that this function can be preserved.
