46 years, Female, breast cancer metastases to brain post surgery and radiation therapy. Surveillance. There are postoperative findings related to resection of right medial cerebellar metastasis. There is linear enhancement along the resection cavity and persistent T2 FLAIR hyperintensity. Slight decrease in size of enhancing right pontine lesion measuring 11 x 7 mm, previously 11 x 12 mm, with decreased associated T2 hyperintensity. There is no new mass or mass effect. No midline shift or herniation. The right medial occipital enhancing nodule is not significantly changed. There are unchanged faint punctate foci of enhancement within the right corona radiata and the left middle frontal gyrus. There is encephalomalacia of the anterior aspect of the left superior medial frontal lobe, unchanged. There is scattered cerebral white matter T2 hyperintensity, which is nonspecific. There is no restricted diffusion to suggest acute ischemia. There is intracranial hemorrhage. The ventricles are within normal limits in size and configuration. Major flow-voids are preserved.
1.No new or enlarging lesion is identified to suggest disease progression. Slight interval decrease in size of right pontine lesion and decrease in surrounding edema. Additional tiny enhancing foci are not significantly changed.2.No significant change in postoperative findings related to resection of a right medial cerebellar metastasis, with no evidence of recurrence.3.No evidence of recurrence within the left anterior frontal lobe treatment bed.
