Comatose status post PEA arrest on 12/14/2015. Evaluate anoxic brain injury. Prominent restricted diffusion involving the gray matter and to lesser extent subcortical white matter of the entire cerebral cortex. There is also restricted diffusion within the caudate heads bilaterally. Pattern is compatible with an acute to subacute anoxic brain injury.There is only mild associated edema and no significant mass effect. The lateral ventricles and basal cisterns remain widely patent. Scattered foci of periventricular white matter T2 hyperintensity compatible with chronic small vessel ischemic changes.The expected intracranial vascular flow voids are present.No intracranial hemorrhage. Prominent opacification of the paranasal sinuses as well as the bilateral mastoid air cells. Postoperative changes from a left cataract removal.
Findings compatible with acute to subacute anoxic brain injury involving the near entirety of the cerebral cortex as well as partial involvement of the basal ganglia. No significant associated mass effect or herniation.
