Female, 67 years old, with history of breast cancer, now multiple lung nodules, concern for brain metastases. Extensive patchy periventricular T2 hyperintensity is seen. A chronic infarct is suspected within the left cerebellar hemisphere. No evidence of restricted diffusion is detected.No findings are seen to suggest parenchymal edema or mass effect. On postcontrast images, no pathologic parenchymal or extra-axial enhancement is detected.No evidence of significant intracranial hemorrhage is detected. There are a few scattered punctate foci of susceptibility, for example within the bilateral thalami, which may reflect chronic microhemorrhage. No abnormal fluid collections are seen. The ventricles are normal in size and morphology.
1.Evidence of advanced chronic microvascular disease and at least one small chronic infarct in the left cerebellum.2.No findings to suggest intracranial metastatic disease.
