Figure 1: A 14-year-old male with right-sided hemiparesis started 3 hours before MRI. (a) Plain CT scan does not show significant density abnormality. (b) MRI T2-weighted Fluid Attenuated Inversion Recovery image does not show significant signal intensity abnormality of cerebral parenchyma even if hyperintensities of distal branches of middle cerebral artery are visible and suggest vessel occlusion (arrow). (c) MRI Diffusion-weighted image shows bright signal of left insular and temporal cortex indicating cytotoxic edema (arrows). (d) 3D-Time of Flight MR-angiogram shows poor representation of distal branches of left middle cerebral artery (arrows).
