 There are multiple, approximately 10, nodular and peripherally-enhancing lesions at the grey-white matter interfaces. For example, the largest infratentorial lesion measures up to 7 mm in the left middle cerebellar peduncle and the largest supratentorial lesion measures up to 8 mm in the right inferior frontal gyrus. There is negligible edema associated with the lesions. There is no evidence of intracranial hemorrhage or acute infarct. There is a small developmental venous anomaly along the inferior and anterior aspect of the right thalamus. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits and scalp soft tissues are grossly unremarkable. There are small mucous retention cysts in the bilateral maxillary sinuses.
Multiple subcentimeter supratentorial and infratentorial lesions are compatible with intracranial metastatic disease.
