摘要
为了回顾性研究肺癌脑转移瘤CT特征的表现，对经手术病理证实的42例肺癌脑转移CT特征的表现进行了总结分析。结果发现：肺癌脑转移的CT表现常多发于大脑皮质或皮质下区，腺癌脑转移以结节状瘤灶多见，瘤旁水肿程度不一。鳞癌脑转移以环状强化多见，瘤旁水肿重，占位效应明显。对等密度无水肿转移瘤灶提示增强扫描的重要性。对肺癌单发脑转移的诊断及转移时间也进行了探讨。从多方面认识到不同的肺癌脑转移瘤有不同CT特征表现。
To retrospectively study the CT characteristics of brain metastasis from lung cancer, the CT appearances of 42 cases of confirmed brain metastasis from lung cancer were analyzed. The CT findings of intracerebral metastasis from lung cancer often occurred at cerebral cortex and subcortex. Intracerebral metastasis of adenocarcinoma appeared as focus of tubercle, and peritumoral edema degree was varied. Metastasis squamous cell carcinoma appeared as ring-shaped enhancement, peritumoral edema was serious, and the occupying effect were obvious. The contrast enhancement was important in equated density metastasis lesions without edema.The diagnosis of single metastatic lesion and the time of metastasis were discussed. The characteristic manifestations of CT in the brain metastasis from lung cancer were varied.
