摘　　要：目的探讨颅脑损伤后神经源性肺水肿(neurogenic pulmonary edema,NPE)X线表现与其发病机制的相关性。资料与方法结合NPE的发病机制学说,回顾分析8例符合NPE临床诊断标准患者的胸部X线表现,5例为重型颅脑外伤,其中2例为术后;3例为自发性颅内出血,其中2例为术后。结果8例颅脑损伤继发NPE患者均表现为两肺弥漫性水肿,其早期胸部X线表现为两肺透亮度降低,两肺肺纹理增多、增粗、模糊,晚期则表现为多发斑片状或融合成大片状、云雾状模糊阴影。结论NPE胸部X线表现具有特征性,主要与其发病机制中的毛细血管渗透学说相关。Objective To analyze the correlation of X-ray manifestation and pathemechanism in neurogenic pulmonary edema（NPE）after brain injury.Materials and Methods The chest X-ray of 8 patients identified as NPE were analyzed retrospectively：5 cases were severe brain injury including 2 postoperative cases;3 cases were spontaneous intracranial hemorrhage,among them,2 cases were postoperative.Results 8 cases of NPE showed diffuse pulmonary edema. A descent of the brightness,increased and vague pulmonary markings of two lungs were the chest X-ray features of early NPE. Multiple patchy shadows,big patchy shadows,and cloudy shadows were the chest X-ray manifestation of late NPE.Conclusion The NPE has specific chest radiological manifestation,X-ray manifestations are highly correlated with blood capillary permeability.
