52-year-old female with a history of metastatic breast cancer status post whole brain radiation. The enhancing medial right cerebellar lesion measures 3 x 3 mm (series 11, 46), previously 5 x 4 mm. There are two enhancing lesions in the left cerebellar hemisphere. The more superior lesion measures 2 x 2 mm (series 11, image 42), previously 4 x 4 mm and the more inferior lesion is no longer discretely measurable due to faint, indistinct enhancement (series 11, image 27). The enhancing lesion in the white matter adjacent to the lateral right thalamus measures 8 x 5 mm (series 11, image 7), which is unchanged in size, although the surrounding T2 signal abnormality has decreased. No new enhancing lesions are identified. There is patchy T1 hyperintensity in the bilateral globi pallidi. 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. There are no focal skull lesions. The orbits, paranasal sinuses, and scalp soft tissues are grossly unremarkable.
1.Interval decrease in size of metastatic lesions in the left and right cerebellum.2.Unchanged size of a lesion in the deep white matter adjacent to the right thalamus, but with a decrease in surrounding edema.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
