Figure 1: Axial sections of contrast-enhanced MRI brain showing FLAIR (a) hyperintensity in bilateral thalami which show intense restriction of diffusion (b) with corresponding low ADC values (c) and blooming on gradient sequence (d) in center part of lesions giving “double doughnut sign” appearance. There is symmetrical T2 hyperintensity (e) in bilateral deep cerebellar white matter. There was no enhancement in postcontrast T1-weighted images (f)
