摘要
目的探讨CT特征分析对不典型或早期高原肺水肿(HAPE)的诊断价值。方法回顾性分析50例经临床诊断为早期HAPE的患者胸部CT特征,总结CT对早期高原肺水肿的诊断价值。结果50例中,病灶发生部位累及单侧肺35例,其中右肺25例,左肺10例;累及双侧肺15例。35例病变局限于1个肺叶,10例病变发生在2个肺叶,5例病变累及3个及以上肺叶。CT表现早期HAPE胸部CT影像学特征包括双肺支气管-血管束增多、增粗,浅淡磨玻璃样改变,多角形、类圆形及小斑片状密度增高影,网格状改变,肺野外带结节影,主肺动脉内径增宽,叶间胸膜增厚,代偿性肺气肿等。结论胸部CT检查是诊断HAPE的重要方法之一,可明显提高早期或不典型HAPE的诊断准确率。
Objective To evaluate the diagnostic value of CT features in atypical or early high-altitude pulmonary edema(HAPE).Methods The CT features of chest of 50 patients with early HAPE were analyzed retrospectively,and the diagnostic value of CT in early HAPE was summarized.Results Among the 50 cases,35 cases involved unilateral lung and 15 cases involve bilateral lung,including 25 cases of right lung and 10 cases of left lung.Bilateral lung was involved in 15 cases.The lesions were localized in one lobe in 35 cases,in two lobes in 10 cases,and in three or more lobes in 5 cases.Early HAPE chest CT imaging features included increased and thickened bronchial-vascular bundles in both lungs,light ground-glass like changes,polygonal,quasi circular and small patchy high-density shadows,grid-like changes,nodule shadows in the lateral field of the lung,widened inner diameter of main pulmonary artery,thickened interlobular pleural,and compensatory emphysema.Conclusions Chest CT examination is one of the most important methods in the diagnosis of HAPE,which can significantly improve the diagnostic accuracy of early or atypical HAPE.
