Ganser syndrome and lesion in the temporoparietal region

Ganser syndrome is a rare dissociative disorder. It has been reported in association with various functional psychiatric disorders and organic states, most often in patients with head injury and stroke, especially those involving the frontal lobes. The present case of Ganser syndrome had features of hysterical dissociation but was found to have haemorrhage in the temporoparietal region of the dominant hemisphere. The complexities of Ganser syndrome in the presence of an organic lesion with an overwhelming emotional component are discussed.
