Abstract
A boy with a focal lesion of the right cingulum, subjected to cingulectomy for the removal of a tumor [astrocytoma grade 1], is the 1st reported case of an isolated unilateral cingulum lesion. The presenting symptoms consisted of serious behavioral abnormalities: lack of social restraint, heightened sexuality, bulimia and aggressiveness, all of which ceased after surgery. Neuropsychological tests, done before and after the operation, provided no evidence that the higher cognitive functions, including memory were impaired.
