53-year-old female status post cardiac arrest, new ischemic stroke, evaluate for prognostication purposes. There is evidence of prominent restricted diffusion in multiple areas throughout the brain including the bilateral thalami, cerebellar hemispheres and vermis, posterior frontal, parietal, temporal, occipital lobes, and perhaps portions of the bilateral basal ganglia. There is associated vasogenic edema most prominently involving the left parieto-occipital region but also involving the right parietal occipital region. There is gyriform hyperintense T1 and susceptibility abnormality within the left parieto-occipital region compatible with subacute hemorrhage. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. There is mild paranasal sinus fluid and mucosal thickening. There are partly imaged postoperative findings in the cervical spine. There appears to be swelling of the anterior tongue. The patient is intubated as well. There is diffuse low signal of the bone marrow, which may be related to renal osteodystrophy.
1. Bilateral subacute ischemic lesions mainly involving the bilateral posterior cerebral hemisphere with subcortical vasogenic edema and subacute petechial hemorrhagic conversion involving left parietal-occipital regions, perhaps indicating superimposed posterior reversible encephalopathy syndrome.2. Swelling of the anterior tongue may indicate angioedema or the effects of compression.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
