A 70-year-old female was admitted due to progressive paraparesis, paresthesias, and urinary retention for 2 months. After 2-year of ATT, her situation improved. The MRI changes are as follows: (a) sagittal T2-weighted image reveals a long, high intensity signal from C1 to T1 in the spinal cord before treatment regimen, (b) T1W contrast image showing patchy enhancement and thickening of the cord, (c) the diffuse lesions on axial T2-weighted images, (d) a year later the swelling of the cervical spinal cord disappeared on sagittal T1-weighted images, (e) the hyperintensity resolved following 1 year of ATT, and (f) no lesion is visible on axial T2-weighted images.
