Axial MRI from the referring hospital and on admission to our hospital. MRI findings of FLAIR (A) and T1-weighted image with Gd enhancement (B) from the referring hospital (1.5T). Increased white matter lesions are visible in the right parietal lobe on FLAIR images (A), and a T1-weighted Gd enhanced image revealed abnormal enhanced parenchymal lesions along the parietal sulci (B). On admission, these lesions worsened in both FLAIR (C) and T1-weighted enhanced images (D). High signal intensity in the apparent diffusion coefficient (ADC) map (E) and low signal intensity in the diffusion-weighted image (F) suggested its edematous nature. No microhemorrhages were observed with Gradient recalled echo-T2* imaging (3T) (G).
