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.
一名60岁女性因颅部计算机断层扫描显示小脑幕下表面附着有钙化肿瘤而出现轻度小脑功能障碍，胸部X光片显示肺部有肿块。钙化的性质和位置使得术前鉴别转移性脑肿瘤和脑膜瘤很困难。手术随后发现脑肿瘤是肺腺癌的转移灶。转移性脑肿瘤可以钙化，在颅内钙化病变的鉴别诊断中应予以考虑。
