Mirror speaking after neurosurgery. A case history.

The case is reported of a 23 year old patient, who at the age of nine underwent neurosurgery for an angiomatous meningioma of the right temporal lobe, and immediately afterwards realized he was able to speak backwards nearly as well as normally. Presently, the patient still retains this ability which is associated with analogous mirror reading and writing. Neurological examination and EEG, CT data as well as the scores of some neuropsychological tests are added.
