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

Figure 3 Magnetic resonance imaging brain findings of an 18-year-old female patient during hospitalization and on follow up. A: Axial T2 weighted image showing multifocal subcortical and deep white matter hyperintensities in the bilateral cerebral hemispheres; B: Axial Fluid attenuated inversion recovery (FLAIR) image showing multiple white matter hyperintensities; C: Sagittal T2 weighted image revealing involvement of the corpus callosum; D: Axial T1 weighted image showing hypointense lesions with internal, hyperintense foci in the affected areas; E: Axial Susceptibility weighted imaging (SWI) phase image demonstrating a negative phase effect, suggestive of hemorrhagic components. F: Axial post contrast T1 weighted image showing no obvious enhancement; G–J: Follow-up T2-weighted (G, H) and FLAIR (I, J) images showing resolution of previously noted white matter hyperintensities; K and L: Follow up SWI images revealing an increased number of hemorrhagic residues compared to initial imaging.
