There is hypoattenuation in the basal ganglia and thalami with loss of the normal gray-white differentiation (dashed lines). There are findings of diffuse cerebral edema with effacement of all basilar cisterns, cerebral sulci, and the ventricles. In addition, there is a “pseudo-subarachnoid” hemorrhage appearance (green arrows) caused by the edematous and hypodense brain being in close apposition to the normal MCA and ACA branches which appear hyperdense. Notice also how hyperdense the dura (e.g. falx, tentoria) appear compared to the edematous brain. These are all findings of profound hypoxic ischemic injury.
