54 years, Female, metastatic pancreatic cancer to brain, status post SRS. Examination for repeat SRS. Limited post gadolinium 3-D T1 and susceptibility weighted sequences of the brain were obtained per radiation treatment planning protocol.There is a 2 mm enhancing lesion in the left cerebellar hemisphere, series 501 image 46, which is suspicious for metastasis and as seen on recent MRI from 4/26/2016. No associated hemorrhage.Again seen is a small resection cavity involving the left inferior parietal lobule without mass or enhancement to suggest recurrent tumor. There is susceptibility related to chronic blood products in this region. No other suspicious intracranial enhancement is appreciated. A cavernoma with an associated developmental venous anomaly is again seen in the right parietal lobe showing no significant interval change. No evidence of hydrocephalus, intracranial mass effect, midline shift, or herniation.
1. Examination for repeat radiation treatment planning. Again seen is a 2 mm left cerebellar hemisphere enhancing lesion suspicious for metastasis.2. Evidence of left parietal tumor resection without evidence of recurrence.3. Stable right parietal cavernous malformation.
