Eating the meat of pheasants which was killed by potassium cyanide, a 27 year old man developed several symptoms of minor intoxication. A few days later, the patient became mute, apathy, somnelent and indifferent but without any parkinsonia features or dementia. On CT brain scan, bilateral symmetrical and non-enhancing focal low densities are noticed in basal ganglia, similar to the carbon monoxide intoxication.
