(A) Axial FLAIR and (B) gradient echo (GRE) MR images at the level of basal ganglia show multifocal FLAIR hyperintense lesions at gray-white matter junction and in bilateral basal ganglia. None of the lesions shows evidence of hemorrhage (B)

Magnetic resonance imaging (MRI) (Siemens Avanto, Erlangen, Germany) was performed the next day which revealed multifocal T2-weighted (T2W) and fluid attenuated inversion recovery (FLAIR) hyperintensities in bilateral cerebral hemispheres including basal ganglia [Figure 1].
(A) Axial DWI MR image at the level of basal ganglia shows restricted diffusion within these lesions. (B) Contrast-enhanced T1W MR image shows peripheral rim enhancement of the lesions

Some of these regions showed restricted diffusion and subtle peripheral contrast enhancement [Figure 2].
Follow-up GRE MR image, done after 72 h, shows multifocal areas of blooming within the lesions, suggestive of hemorrhage

Repeat MRI was performed which revealed hemorrhages [Figure 3] in the lesions that were noted previously.
