Metastatic NSCLC. There is interval decrease in size of a lesion along the right postcentral sulcus that measures up to 5 mm, with a small amount of susceptibility effect, which has not significantly changed. Some of the images are degraded by patient motion, but there is no definite evidence of additional brain metastases. There are mild scattered foci of nonspecific high T2 signal in the cerebral white matter without enhancement. There is no evidence of acute infarct. There is no midline shift. The ventricles are unchanged in appearance. There is an persistent nonspecific left parietal scalp lesion that measures up to 12 mm.
1. No significant change in size of the treated metastasis in the right postcentral sulcus. 2. Persistent nonspecific left parietal scalp lesion.
