肺癌脑转移156例的MRI特征分析

MRI Characteristics of Lung Cancer with Brain Metastases

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156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:156例中,单发转移47例,多发转移109例;腺癌73例,鳞癌59例,小细胞癌19例,大细胞癌5例;156例479个转移灶中,腺癌279个,鳞癌132个,小细胞癌49个,大细胞癌17个;各种病理类型的肺癌脑转移病灶中,鳞癌重度水肿比例最高(56.06%),囊性变最多(44.10%),腺癌转移瘤卒中出现率最高(30.47%)。结论:不同组织类型的肺癌脑转移有不同的MRI表现特点。

Objective：To analyze the MRI characteristic of different histopathological type lung cancer with brain metastases.Methods：A total of 156 patients with MRI and pathologically proved intracranial metastases from lung cancer with certain histopathology were reviewed retrospectively.Results：In 156 patients,that were simple metastases 47 cases,multiple metastases 109 cases;the primary tumor was lung adenocarcinoma in 73 cases,squamous cell cancer in 59 cases,small cell cancer in 19 cases,large cell cancer 5 cases;in 479 metastases of 156 patients,it was adenocarcinoma 279 masses,squamous cell cancer 132 masses,small cell cancer 49 masses,large cell cancer 17 masses.In different histopathological type brain metastases of lung cancer,it was the highest rate（56.06%） of serious edema and the most cystic rate（44.10%） for squamous cell cancer,it was the highest rate（30.47%） of stroke for adenocarcinoma metastases.Conclusion：Various MRI features may used to prove brain metastases of different histopathological type of lung cancer.
