Metastatic head and neck caner with suspicious lesion on head CT. There are at least six bilateral cerebral hemisphere nodular and ring-enhancing lesions with minimal to mild vasogenic edema. For example, the largest measures up to 9 mm in the left middle frontal gyrus. There is also a punctate enhancing lesion in the left cerebellar hemisphere. There is no evidence of acute intracranial hemorrhage or cerebral infarction. The ventricles are normal in size and configuration. There is no midline shift or herniation. The orbits, paranasal sinuses, and mastoid air cells are unremarkable.
1. Several subcentimeter supratentorial and infratentorial subcentimeter lesions are compatible with metastases.2. Multiple skull lesions are also compatible with metastases.
