Alien hand syndrome is a perplexing and uncommon clinical diagnosis. We report an unusual manifestation [i.e. "spontaneous masturbation"] of alien hand syndrome in a 73-yr-old man with a right anterior cerebral artery infarct affecting the right medial frontal cortex and the anterior portion of the corpus callosum. We conclude that alien hand syndrome should be considered in patients who present with a feeling of alienation of one or both upper limbs accompanied by complex purposeful involuntary movement.
