A 19-year-old man with paroxysmal kinesigenic dyskinesia (PKD) taking 200mg carbamazepine per day for six years was admitted to our hospital because of a medical certificate for soldiers. The dyskinesias were usually precipitated by sudden movements and these attacks occurred several times a day and had a brief duration (less than one minute). The drug was abruptly withdrawn seven days before the brain imaging and video-electroencephalography monitoring. Magnetic resonance imaging showed cytotoxic edema in the splenium, which were completely resolved three months later (Figure).
