Axial T2W (a) and FLAIR (b and c) images showing edematous and hyperintense cortical and subcortical area of bilateral parieto-occipital regions (a and b) in symmetrical distribution along with hyperintensity in cerebellar white matter and medulla (c). Sagittal FLAIR image (d) showing medullary and cervicomedullary junction hyperintensity. T2W = T2-weighted, FLAIR = fluid-attenuated inversion recovery

MR angiography (time of flight) of renal arteries were normal. Magnetic resonance imaging (MRI) showed altered signal intensity areas involving bilateral cortical and subcortical parieto-occipital regions, bilateral cerebellar hemispheres, medulla, cervicomedullary junction, and cervical spinal cord until C6 vertebral level [Figures 1 and 2].
