    Abstract:
    A 36 year-old woman beginning with spastic paraparesis at her age of 11 visited us for evaluation of progressive muscular weakness of the distal portions of the upper extremities and difficulty in speaking at her age of 33. The neurological features at the present are as follows; fine horizontal gaze-nystagmus, impaired smooth pursuit ocular movement, highly spastic paraplegia with pes equino-varus necessitating canes and the wheel-chair, highly accentuated PTRs and ATRs associated with positive Babinski's sign, diminished or absent deep reflexes in the upper extremities, moderate muscular wasting with fasciculation on the tongue and distal portions of the upper extremities (rt less than lt). Sensory or cerebellar functions remain normal. No autonomic finding has been manifested. The HTLV-I antibody titers of serum (eg. PA method: x8192 ) and cerebrospinal fluid are highly positive in various methods. That of her mother (no blood-transfusion history) is positive. The provirus genome analysis on peripheral lymphocytes using the Southern blotting method by the cleaving enzyme Psi I was unable to discriminate that of an ATL patient. MRI of the central nervous system revealed higher signal area (short SE) at the C5/6 region and atrophy of C7/8 region. Neither a definite lesion in the lower brain stem, cerebellum nor cerebral hemispheres was identified. The skeletal muscle X-ray CT on the lower extremities revealed the atrophic flexor thighs and the anterior tibial and peroneal muscles. Needle EMG showed the prominent neurogenic changes in the atrophic muscles. Oral prednisolone therapy for four months relieved nystagmus and difficulty in walking, slightly. She, however, discontinued because of its side effect.(ABSTRACT TRUNCATED AT 250 WORDS)
