SCLC with brain treated metastases, now with new word finding difficulties. There has been interval decrease in size and/or resolution of the intracranial metastases. For example, a right inferomedial cerebellar lesion measures 5 mm in diameter, previously 10 mm. There is unchanged extensive white matter T2 hyperintensity diffusely. There is no evidence of acute infarct. There is an unchanged nonspecific punctate focus of susceptibility effect in the inferior pons. The ventricles and basal cisterns are unchanged in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.
