Calcified metastatic brain tumor--two case reports.

A 29-year-old man and a 46-year-old woman presented with calcified brain metastasis from pulmonary adenocarcinoma. Both patients had a relatively benign clinical course and prolonged survival after total removal of the tumors. The male patient was still alive 2 years 3 months after surgical resection of the metastatic and primary tumors. The female patient had had brain metastasis 8 years after surgical resection of lung cancer, and survived for 3 years 3 months after removal of the brain metastasis. The MIB-1 indexes of the two cases were relatively low compared with other cases of brain metastases. Calcification and low MIB-1 index may indicate longer survival in patients with metastatic tumors if the primary tumor is controlled.
