4 patients with malignant right parietal brain tumors (2 with gliomas and 2 with metastases) presented with difficulties in driving due to visual hemineglect, thought at first to be due to absent-mindedness or forgetfulness. Visual neglect is one aspect of the syndrome of unilateral neglect, which is a selective disturbance in the internal representation of the body image and processing of information from the extrapersonal space. The cerebral mechanisms underlying the phenomenon are reviewed.
