Klinefelter's syndrome with atypical presenting features.

The authors thought it would be of interest to present this case which proved to be Klinefelter's syndrome with "xxy" pattern, as the patient presented with episodes of abnormal behaviour lasting for a few minutes. Ho would suddenly become anxious, look perplexed, start clenching his fists and at times complain of thoughts tha some persons were trying to attack him. He also felt as if he were hearing voices talking to him. Observation in the hospital and EEG recording helped to rule out temporal lobe epilepsy and a diagnosis of Klinefelter's syndrome with personality disorder and psychogenic attacks of abnormal behaviour was made at the time of discharge.
