82 years, Male, stage III non-small cell lung cancer. No intracranial mass or mass-effect. No abnormal parenchymal or meningeal enhancement. Several foci of T2/FLAIR hyperintensity are seen in the bilateral subcortical and periventricular white matter, which are nonspecific, but compatible with mild chronic small vessel ischemic changes. There is global parenchymal volume loss commensurate with patient's advanced age. No restricted diffusion to suggest acute ischemia. No intracranial hemorrhage. The ventricles are within normal limits in size and configuration. Major flow-voids are preserved.Sella and orbits are grossly within normal limits. There are bilateral lens implant. Paranasal sinuses and mastoid cells are grossly clear. No suspicious lesions in the calvarium.
1. No evidence of intracranial metastatic disease.2. Mild chronic small vessel ischemic changes and global parenchymal volume loss which is appropriate for patient's age.
