Abstract
BACKGROUND: Leptomeningeal metastases (LM) is one of the most serious complications of advanced non-small cell lung cancer (NSCLC) due to the lower quality of life and poor prognosis. The aim of this study is to analyze the clinicopathological features and prognosis of patients with LM from NSCLC (NSCLC-LM).Entities:

1脑MRI改变。A:2015-01-12 T2FLAIR序列未见明确转移灶; B and C:2015-05-17治疗前; MRI:T2FLAIR相冠状位及T1WI矢状位图像与A图像比较, 双侧顶叶脑沟变窄; D:2015-05-17治疗前; MRI:轴位T1WI增强序列显示双侧额顶叶沿脑沟分布的线状明显强化影; 右侧软脑膜增厚并明显强化; E:2015-09-18治疗后; MRI:轴位T1WI增强序列显示, 双侧额顶叶脑沟内线状强化影有所减少。
Patterns of brain MRI.A:No metastases in the T2FLAIR image; B and C:2015-05-17;MRI:before treatment:The coronal T2FLAIR and sagittal T1WI image demonstrated shallow sulcus in bilateral parietal lobe compared with image A; D:2015-05-17;MRI:before treatment:The axial T1WI enhanced image showed linear enhancing meninges along the surface of bilateral frontal and parietal lobe; meninges was thicking and enhancing on the right side; E:2015-09-18 MRI after treatment:The axial T1WI enhanced image showed decreased along the surface of bilateral frontal and parietal lobe.
