title: [A case of multiple sclerosis with alien hand (diagonistic dyspraxia)].
abstract: In this paper, we describe a case of mutiple sclerosis (MS) with diagonistic dyspraxia and the callosal lesions in MRI. The patient was a 54-year-old woman with 12 year-history of suffering from MS. Her clinical symptoms were left alien hand, mild euphoria, right blindness, left visual deficit (0.06), mild weakness of right upper limb, complete paraplegia of lower limbs, total sensory deficit below middle sternal level and neurogenic bladder. She was right-handed person and her alien hand was such a manner; when she intended to use spoon with right hand, her left hand aimlessly began to hold and release a cup or dish. Then, she was diagnosed as diagnostic dyspraxia. Neuropsychological examinations disclosed left hemispheric dysfunction including left hand agraphia and disconnection of the callosum. MRI showed patchy lesions in the callosum, right optic radiation, both side thalamus (left > right), left cerebral peduncle, and spinal cord of cervical to the thoracal portion. Although the functional disorders and the radiological atrophy of the callosum, the clinical manifestation of the callosal disconnection in MS cases has been scarcely reported, and this case seems to be a quite rare condition to be described.
