Surveillance of brain metastases from melanoma. There is redemonstration of small, nonenhancing foci of gliosis in the left pons and right genu of the corpus callosum appearing similar to the prior study. There were enhancing lesions in these locations on remote prior studies. There is an additional small focus of gliosis involving the callosal splenium on the left which is unchanged and may be related to prior metastasis, ischemia or other injury. There is no evidence of abnormal intracranial enhancement on the current study to suggest active metastatic disease. There is no mass effect, midline shift or herniation. The ventricles and cisterns are normal in size and configuration. The major cerebral flow voids are intact. There are small mucous retention cysts in the maxillary sinuses. There is diffuse T1 hypointensity of the bone marrow without discrete destructive osseous lesions, which may represent marrow reconversion. The orbits are unremarkable.
No evidence of active intracranial metastatic disease.
