Lung cancer, s/p chemoRT, planning for resection. There are unchanged subcentimeter foci of susceptivity effect and adjacent streaky enhancement in the right middle frontal gyrus white matter. There are a few nonspecific cerebral white matter T2 hyperintense foci. There is no evidence of acute infarct. There are trace bilateral frontal convexity subdural effusions. 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, paranasal sinuses, and scalp soft tissues are grossly unremarkable. There are biparietal foramina. There is unchanged dorsiflexion of the dens.
1. The abnormalities in the right frontal lobe may represent mineralization from prior injury or inflammation, cavernous malformations, and/or microhemorrhages, perhaps related amyloid angiopathy, as opposed to metastatic disease. 3. Unchanged dorsiflexion of the dens.
