1.5-T MRI of brain at the 5 months follow up. Abnormal hypointensity on T1-weighted images (A), hyperintensity on T2-weighted images (B), and hypointensity on fluid-attenuation inversion recovery (FLAIR) images are observed in the brain lesions’ core (C). Additionally, hyperintensity around the brain lesions’ core on FLAIR imaging (D) suggested the softening of the lesions and secondary gliosis, as seen on coronal MRI slices. Hyperintensity on diffusion-weighted imaging (DWI) in the brain lesions disappeared (D) and hyperintensity on apparent diffusion coefficient (ADC) imaging increased (E), as seen on coronal MRI slices. Brain abscesses showed slight enhancement, as seen on the MRI sagittal image (F). White and black arrows indicate lesions
