NSCLC restaging. Some of the images are degraded by patient motion. There are two punctate foci of susceptibility effect in the left frontal and parietal lobes without associated enhancement. Otherwise, there is no evidence of gross tumors. There is a small linear area of high T2 signal and restricted diffusion in the right cerebellar hemisphere. There is mild diffuse cerebral volume loss. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, and scalp soft tissues are grossly unremarkable. There is right maxillary sinus retention cyst formation. There is mild fluid within the right mastoid air cells.
1. Two punctate foci of susceptibility effect in the left frontal and parietal lobes without associated enhancement are nonspecific and may represent chronic microhemorrhages. No evidence of intracranial metastases otherwise. 2. Small acute infarct in the right cerebellar hemisphere.
