Figure 2

Typical four typies images of EBLs are displayed according to the following MRI sequences, as available: fluid-attenuated inversion recovery (FLAIR), T1W+Gd, diffusion-weighted imaging (DWI), apparent diffusion coefficient. The top rows represent neuroimaging at time of EBLs appeared, and the bottom rows represent post-EBLs repeated neuroimaging. Tumefactive-like lesion: No enhanced tumefactive-like lesions in cerebellar hemisphere shrink in repeating imagings of two months later. ADEM-like lesion: No enhanced extensive bilateral white matter brain lesions are markedly expanded in the subsequent MRI of three months later. PRES-like lesion: No enhanced lesions in left occipital lobe completely resolve in less than four weeks. MS-like lesion: No enhanced multifocal lesions locate in the periventricular and subcortical white matter. The MR images of follow-up are not supplied. The DWI, ADC images and MR images of follow-up are not supplied. All the DWI and ADC images reveal changes consistent with vasogenic edema.
