54 years, Female, pancreatic cancer, surveillance after SRS There is a 2 mm enhancing lesion in the left cerebellar hemisphere, series 10 image 42, which is suspicious for metastasis and not appreciably changed since 4/26/2016. No associated edema or hemorrhage. No new parenchymal or meningeal enhancement is seen. 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. Surrounding FLAIR hyperintensity compatible with gliosis is also not significantly changed in the interval. Minimal additional scattered T2/FLAIR hyperintense foci are nonspecific and not appreciably changed in the interval.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.There is a 6 x 9 mm enhancing lesion involving the squamous portion of the right temporal bone, which in retrospect measures 3 x 5 mm on prior MRI from 4/26/2016. No significant osseous intracranial mass effect.
1. Compared to 4/26/2016, there is no significant change in size of 2 mm left cerebellar enhancing lesion likely representing metastasis. No new parenchymal or meningeal enhancement.2. Enlarging right temporal calvarial lesion, likely representing metastasis, measures 6 x 9 mm, previously 3 x 5 mm on 4/26/2016. No associated intracranial mass effect.3. Evidence of left parietal tumor resection without evidence of local recurrence.4. Stable right parietal cavernous malformation.
