Male 34 years old s/p arrest, remains comatose, evaluate for extent of brain injury, unresponsive off sedation >24 hrs Focus increased diffusion and mildly decreased ADC signal in the posterior right temporo-occipital lobe (401/271) and left inferior cerebellar vermis (401/264) with associated FLAIR abnormality suspicious for subacute infarctions. Mild susceptibility artifact within the right temporo-occipital lobe suggestive of hemorrhagic conversion. Encephalomalacia with surrounding FLAIR abnormality noted within the left inferior parietal lobe involving the supramarginal and angular gyrus suggestive of remote infarct. There is no evidence of intracranial mass. 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. The orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.
1. Subacute infarcts within the right temporo-occipital lobe, which demonstrates hemorrhagic conversion, as well as the left inferior cerebellar vermis. 2. Chronic left parietal infarct involving the supramarginal and angular gyrus.
