On admission day 2, axial fluid-attenuated inversion recovery (FLAIR) images show abnormal hyperintense areas bilaterally in the cerebellar hemispheres, watershed regions, and white and grey matter of the occipital and occipitoparietal lobes. Axial FLAIR images show hyperintense areas in white matter predominating in the periventricular region indicating leukoaraiosis (a, b, c, d, e). Axial diffusion weighted image (DWI) images show hyperintense areas in these lesions and the right thalamus (f, g, h, i, j). Apparent diffusion coefficient (ADC) map shows low signal intensities in the bilateral cerebellar hemispheres and watershed regions (k, o). ADC map shows low signal intensities in the cortical and subcortical regions with small areas of high signal intensity in the surrounding area (l, m, n). These image patterns indicate that the lesions were damaged by extensive cytotoxic edema with restricted vasogenic edema. Most hyperintense areas on DWI on 2 days after admission disappeared by 7 days after admission (p, q, r, s, t)
