(A) Fluid attenuation inversion recovery (FLAIR) image showed hyperintensity in the cortical region of right frontal and parietal lobes without white matter involvement (Case 1). (B) Diffusion weighted imaging (DWI) showed no obvious signal change in the cortex (Case 1). (C) MRI scan showed the abnormality disappeared at the follow-up scan (Case 1). (D) Hyperintensity in the cortical regions of left parietal lobes in MRI FLAIR images 7 years before this episode (Case 1). (E) DWI showed no obvious signal change in the cortex (Case 1). (F) MRI scan showed the abnormal lesions disappeared at the follow-up scan (Case 1). (G) Hyperintensity in the cortical regions of left frontal and parietal lobes in MRI FLAIR images (Case 2). (H) DWI showed mild hyperintensity in the involved cortical regions (Case 2). (I) Gadolinium enhanced T1-weighted image showed meningeal linear enhancements in the sulci of left brain lobes (Case 2). (J) T2-weighted image showed hyperintensity in the spinal cord from thorax 2 to 9 segments. (Case 2).

Two days later, the patient presented with weakness in both lower limbs and a brain MRI scan revealed the presence of diffuse cortical lesions in the left cerebral hemisphere ( Figures 1G-I ). The spinal cord MRI scan identified the presence of myelitis from the T2 to the T9 segments ( Figure 1J ).
