66-year-old female with altered mental status and recent history of PRES. There is interval near resolution of several areas of bilateral posterior cerebral hemisphere cortical and subcortical, superior frontal lobe, as well as bilateral thalami T2 hyperintensity. There are scattered foci of T2 hyperintensity in the bilateral cerebral white matter, a few of which appear to be new or more conspicuous compared to the prior exam. There are no areas of restricted diffusion. There is no evidence of intracranial hemorrhage, mass, or acute infarct. There is an unchanged punctate focus of susceptibility in the left frontal lobe, which is nonspecific, but likely related to trace mineralization or chronic hemosiderin. The ventricles and sulci are unchanged. 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.
Interval near-resolution of abnormality predominantly involving the bilateral posterior cerebral hemispheres likely related to PRES. However, a few nonspecific scattered cerebral white matter lesions appear to be new or more conspicuous, but no evidence of acute infarction. I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
