摘要
目的探讨百草枯中毒患者肺损伤的CT表现及临床价值。方法州顾性分析6例斤争枯中毒患者肺损伤的CT影像学资料，根据中毒时间分早期（1～2d）、中期（3～14d）、晚期（〉14d）3个阶段。对中毒患者进行CT表现与临床表现的对比。结果6例百草枯中毒患者中3例死亡，2例肺纤维化，1例痊愈。早期CT表现：3例无异常。2例磨玻璃样变，1例肺纹理增多、模糊；中期CT表现：6例磨玻璃样变、马赛克征．6例师实变，4例胸膜下线，4例出现伴行支气管扩张，2例少量胸腔积液；晚期CT表现：4例肺实变及纤维化，3例磨玻璃样变、马赛克征，1例胸腔积液，1例纵隔气肿。结论百草枯中毒的临床表现与CT表现基本相符，具有相对分期特征，有助于临床对病情的及时评什，从而指导临床治疗。
Objective To investigate the CT features of pulmonary injury in paraquat poisoning. Methods The chest CT image of lung injury in 6 cases of paraquat poisoning were analyzed retrospectively. According to different period of poisoning, the 6 cases were divided into 3 types： the early stage of poisoning （within 2 d）, the middle stage of poisoning （3-14 d）, the late stage of poisoning （〉14 d）. A comparison between CT signs and the pathological features of patients was made. Rusults Among this 6 eases, 3 cases died, 2 cases pulmonary fibrosis was noted, 1 cases recovered. According to different period of poisoning, the 6 cases were divided into 3 stages： in the early stage of poisoning （within 2 d ）, 3 cases of all patients showed nothing remarkable, 2 cases showed ground-glass opacity, 1 case showed fuzzy lung-marking. In the middle stage of poisoning （3-14 d）, all 6 cases showed ground-glass opacity, mosaic attenuation; 6 cases showed pulmonary consolidation; 4 cases showed subpleural lines; 4 cases showed bronchiectasis; 2 cases showed mid-lower pleural effusion. In the late stage of poisoning （〉14 d）, 4 cases showed pulmonary consolidation and pulmonary fibrosis, 3 cases showed ground-glass opacity and mosaic attenuation, 1 case showed mid-lower pleural effusion; 1 case showed mediastinal emphysema. Conclusion The clinical pathology process of paraquat poisoning was in line with CT finding which was related with clinical stage and was helpful for clinical assessment of paraquat poisoning promptly and to guide the clinical treatment.
