Metastasis to the midbrain. Report of two cases.
Two patients with metastasis from lung carcinoma of the midbrain are presented. The computerized tomographic (CT) findings mimicked a primary pineal tumor, but autopsy confirmed a metastatic nodule in the midbrain in both cases. The rational approach to posterior third ventricular tumors seen on CT in adulthood is discussed.
