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。
In order to retrospectively study the CT features of brain metastases from lung cancer, the features of CT features of 42 cases of brain metastases confirmed by pathology were analyzed. The results showed that the CT manifestations of brain metastases from lung cancer were often found in the cerebral cortex or subcortical areas. The brain metastases of adenocarcinoma were more common with nodular tumors, and the degree of peritumoral edema was not uniform. The squamous cell brain metastasis was more common in the ring enhancement, and the peritumoral edema was heavier with a significant space-occupying effect. Equal density noduplication metastases suggest the importance of enhanced scanning. The diagnosis and metastasis time of single brain metastases from lung cancer are also discussed. It is recognized in many aspects that different lung cancer brain metastases have different CT features.
