 The image quality is somewhat degraded by motion artifact. There is no evidence of intracranial hemorrhage, mass, or acute infarct. There is no abnormal intracranial enhancement. There are scattered nonspecific punctate foci of abnormal T2 hyperintensity within the periventricular and subcortical white matter and left cerebellar hemisphere, which may represent chronic small vessel ischemic changes. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. There are extensive calvarial, skull base, and upper cervical spine lesions, consistent with treated metastases.
1. No definite evidence of intracranial metastases.2. Multiple osseous metastases, with involvement of the central skull base, which can account for cranial nerve deficits.
