Female, 60 years old, with history of metastatic lung adenocarcinoma, surveillance scan. Two subcentimeter foci of enhancement seen previously within the right postcentral gyrus, and a third within the left superior frontal gyrus, are no longer evident. Mild associated T2 hyperintensity has also resolved in these locations.No evidence of any new enhancing or nonenhancing intracranial lesion is seen. Ill-defined periventricular T2 hyperintensity is again seen compatible with prior therapy. No evidence of parenchymal edema or mass effect is seen. No restricted diffusion is detected.There is no evidence of any significant intracranial hemorrhage or abnormal extra axial fluid. The ventricular system is normal in size.
1.Interval resolution of subcentimeter lesions seen in the right post central gyrus and left superior frontal gyrus.2.No new intracranial lesions are evident.
