History of breast cancer and metastases to the brain, status post radiotherapy. As compared to the prior exam, there is interval increase in the size of the enhancing lesions along the periphery of the cerebellar hemispheres, which are associated with vasogenic edema. The lesion along the left inferior paramedian cerebellum demonstrates increased enhancement and measures approximately 8 mm, whereas it measured 4 mm on 1/28/2016. Another lesion along the right lateral cerebellum has also increased in size, measuring 17 mm in its greatest dimension, as compared to 13 mm on the prior exam. Additionally, enhancing lesions are newly apparent in the right paramedian cerebellum and superior left cerebellum vermis. The cerebral hemispheres and brainstem are otherwise unremarkable and there is no evidence of acute infarction or herniation. The ventricles are unchanged, including a punctate cyst in the region of the foramina of Monro. The orbits and skull appear to be intact.
Interval increase in size and number of the cerebellar metastatic lesions.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
