摘要
目的:探讨不同组织学类型肺癌脑转移的MRI表现。方法:回顾性分析36例行MRI检查、经手术病理证实为肺癌脑转移且已明确肺癌组织学类型的病例。结果:36例中,单发转移10例,多发转移26例;鳞癌19例,腺癌13例,小细胞癌1例,大细胞癌3例;36例107个转移灶中,鳞癌71个,腺癌30个,小细胞癌2个,大细胞癌4个;各种病理类型的肺癌脑转移瘤灶中,鳞癌重度水肿比例最高(57.7%),囊性变最多(45.1%),腺癌转移瘤卒中出现率最高(30.0%)。结论不同组织类型的肺癌脑转移有不同的MRI表现。
Objective:To study the MRI findings of brain metastases of lung cancer with different histology.Methods:36 cases of brain metastases of primary lung cancer with different histology confirmed by operation and pathology were retrospectively analyzed.Results:In 36 cases,10 cases were solitary and 26 cases were multiple.The primary tumor was lung adenocarcinama in 13,squamous cell cancer in 26,small cell lung cancer in 1 and large cell carcinoma in 3.In 107focuses of 36 cases was squamous cell cancer in 71,adenocarcinama in 30,small cell lung cancer in 2 and large cell carcinoma in 4.Squamous cell carcinoma had a high proportion of edema and cystic degeneration,adenocarcinama of bleeding.Conclusion: The MRI findings of metastatic encephaloma were different due to a different types of original carcinoma.
