title: Calcified intracranial metastatic tumor mimicking meningioma--case report.
abstract: A 60-year-old female presented with mild cerebellar dysfunction due to a calcified tumor attached to the undersurface of the tentorium cerebelli demonstrated by cranial computed tomography, and a lung mass on a chest x-ray film. The calcified nature and location made preoperative differentiation between metastatic brain tumor and meningioma difficult. Operation subsequently revealed that the brain tumor was a metastasis from lung adenocarcinoma. Metastatic brain tumors can be calcified, and should be considered in the differential diagnosis of calcified intracranial lesions.
