History of inflammatory breast cancer with possible new CNS metastasis. There is subcortical vasogenic edema in the left precentral gyrus and to a lesser extent the right postcentral gyrus. There are otherwise scattered areas of cerebral and pontine white matter T2 hyperintensity. There is no evidence of intracranial hemorrhage or acute infarct. 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 skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable. There are bilateral lens implants.
Subcortical vasogenic edema in the left precentral gyrus and to a lesser extent the right postcentral gyrus may represent metastatic disease, although characterization is limited due to the lack of intravenous contrast. Otherwise, scattered areas of cerebral and pontine white matter T2 hyperintensity may represent chronic small vessel ischemic disease.
