CT and MRI of hypoxic ischemic encephalopathy
Axial CT without contrast of the brain (above) shows diffuse cerebral edema causing loss of the gray matter white matter junction. Axial T1 without contrast (middle left), FLAIR (middle middle) and T2 (middle right) MRI several days later show developing laminar necrosis. Diffusion weighted imaging (below) shows diffusion restriction throughout the gray matter, white matter, and basal ganglia.

The diagnosis was severe hypoxic ischemic encephalopathy.
