A 66-year-old female suffering from HTLV-1 associated myelopathy (HAM) for more than 30 years was hospitalized because of memorial impairment, deafness, dysarthria, dysphagia, and complete paraplegia. She first noticed stiffness and weakness of the right leg at 35 years of age. Gait disturbance was slowly progressed and complete paraplegia developed 18 years later. Neurological examinations on admission revealed that she was bedridden with decubitus, mental deterioration (pre-dementia of subcortical type), bilateral optic nerve atrophy, severe sensory-neural deafness, dysarthria, complete paraplegia, and marked neurogenic bladder. Laboratory data showed mild normocytic anemia and moderate diabetes mellitus. Anti-HTLV-1 antibody titers in serum and CSF were 78,192X and 1,024X, respectively (PA method). Serum levels of soluble IL-2 receptor was markedly elevated (2,200 U/ml). Peripheral blood lymphocytes showed spontaneous proliferation when cultured for 5 days (3H-thymidine uptake; 45,285 cpm/5 X 10(4) cells). MRI examinations of the spinal cord disclosed a predominant atrophy of lower thoracic cord without any compressive lesions. Brain MRI showed diffuse high intensity lesions of the periventricular area on T2 weighted images. Such abnormalities were predominantly found in fronto-parietal region and were quite similar to those of leuko-ariosis. Single photon emission CT using 123I-iodoamphetamine showed hypoperfusion of cerebral white matter on delayed image. It has been reported that intellectual impairment and brain atrophy are not usually seen in HAM patients. The present case, however, shows that such abnormalities of the central nervous system could occur in HAM patients with a long duration of illness.
