Magnetic resonance imaging spectrum of acute hemorrhagic leukoencephalitis: Four case reports

Figure 1 Magnetic resonance imaging brain findings in a 19-year-old female at initial presentation and on follow-up. A-C: Axial T2 weighted images showing multifocal hyperintensities in subcortical and deep white matter with corpus callosum involvement; D-F: Axial Fluid attenuated inversion recovery (FLAIR) images demonstrating confluent hyperintensities in bilateral cerebral white matter and corpus callosum; G: Sagittal T2-weighted image showing fluffy white matter and callosal hyperintensities; H and I: Axial T1 weighted image (H) showing internal hyperintense areas within white matter lesions, which on Susceptibility weighted imaging (SWI) phase image (I) are showing negative phase effect suggestive of hemorrhages; J and K: DWI and apparent diffusion coefficient images showing patchy diffusion restriction; L: Post-contrast T1-weighted image showing no enhancement; M and N: Follow-up T2-weighted images showing resolution of white matter lesions; O: Follow up SWI image showing multiple hemorrhagic residues in white matter; P and Q: Follow-up FLAIR images showing resolution of white matter lesions; R: Follow-up SWI phase image showing multiple residual hemorrhagic foci.
