Lung cancer. There are a few subcentimeter intrinsically T1 hyperintense lesions at the grey-white matter interfaces of the left frontal and right occipital lobes, which may demonstrate superimposed enhancement, are perhaps slightly larger in size than in August 2016. However, there are no new enhancing lesions. There is a background of mild nonspecific cerebral white matter T2 hyperintensity. There is no evidence of acute infarct. The ventricles and basal cisterns are normal 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. However, there is a partially imaged hypointense lesion in the C2 vertebra.
