metastatic breast cancer to brain, post SRS follow up. Again there is a focal enhancing nodular lesion on the left frontal lobe middle frontal gyrus likely located on the subcortical gyrus subcortical white matter. Comparing to prior scan, the size of the enhancement appears to be slightly smaller (3.5mm to 3mm).The right pre central gyrus around the paracentral lobule lesion (about 2mm) does not show any interval change since prior exam.There is no associated perilesional edema. There is no other enhancing lesion on this scan.There is no evidence of acute ischemic or hemorrhagic lesion on this scan.The ventricles, sulci and cisterns are symmetric and unremarkable. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.
No change of right pre-central gyrus close to paracentral lobule lesion since prior exam.Slightly decreased in size of the left frontal middle frontal gyrus lesion since prior exam.
