65 years, Male, new right chest wall mass with preliminary pathology demonstrating NSC. Evaluate for metastatic disease. No restricted diffusion to suggest acute ischemia. No intracranial hemorrhage. No intracranial mass or mass-effect. The ventricles are within normal limits in size and configuration. There is a chronic right pontine infarct which was acute on prior MRI from 2013. There are patchy foci of T2/FLAIR hyperintensity in the bilateral subcortical and periventricular white matter, which are nonspecific, but compatible with chronic small vessel ischemic disease and mildly progressed since prior. There are foci of T2/FLAIR signal abnormality in the right frontal corona radiata as well as in the left anterior subinsular region compatible with chronic infarcts which are new since prior. Post-gadolinium sequences are mildly motion degraded. However there is no abnormal parenchymal or meningeal enhancement. Major flow-voids are preserved. There is a partially empty sella which can be normal variant. Moderate polypoid opacification of the left maxillary sinus is again seen similar to 2/18/2013. There is also a small right maxillary mucus retention cyst. Calvarium and extracranial soft tissue structures are grossly unremarkable.
1. No evidence of intracranial metastatic disease.2. Since 2/18/2013, there has been mild progression of chronic small vessel ischemic disease. There are small chronic infarcts which are new since prior study, as detailed above. Chronic right pontine infarct again seen.
