We report the demonstration by magnetic resonance(MR)imaging of brain involvement in two of four subjects with human T-cell lymphotropic virus type I(HTLV-I)associated myelopathy.The four cases had slowly progressive spastic paraparesis,urinary incontinence,and positive HTLV-I antibodies in serum or CSF or both.Magnetic resonance revealed areas of abnormal intensity in the cerebral hemispheres of two of these cases;one of them also showed brain stem involvement.No spinal cord lesions could be detected in any case by MR. |
