case_images: Magnetic resonance imaging (MRI) of the spinal cord at the first attack showed a long-segment T2 hyperintensity (Figure 1).
case_images: Spinal cord MRI taken during the inflammatory myelitis episode. Sagittal (a-c) and axial (d-f) MR images of the thoracic spine show a long-segment T2 hyperintensity, with increased enhancement observed.. MRI, magnetic resonance imaging.

case_images: Therefore, in September 2023, treatment was switched to inebilizumab [Figure 3(a)]. Before the administration of inebilizumab, the patient's serum CK level remained normal at 88 U/L (1.5 mukat/L) [Figure 3(b)]. Simultaneously, we tracked changes in CK levels in the patient, which gradually returned to normal after 27 days [Figure 3(b)].
