目的提高对肝移植术后肺部感染CT表现的认识,以提高诊断准确率。方法回顾性分析45例肝移植术后肺部感染病例的CT资料。结果CT主要表现为实变影32例,以右下肺或双下肺分布多见;磨玻璃影22例,双肺弥漫性分布多见;结节影10例,均为多发、双肺分布,直径均<3cm(其中直径<1cm者7例),包括两肺弥漫性粟粒样结节3例;网格样影或线样影4例,分布于两肺上叶2例,广泛分布于两肺各叶2例。不同感染类型表现,细菌感染以实变影最常见,其次为磨玻璃影;真菌感染实变影、磨玻璃影、结节影均较常见。结论CT对于肝移植术后肺部感染的诊断具有重要价值。
Objective To improve the understanding of CT findings of pulmonary infection after liver transplantation in order to improve the diagnostic accuracy. Methods The CT data of 45 cases of lung infection after liver transplantation were retrospectively analyzed. Results CT was mainly manifested as consolidation of 32 cases, the lower right lung or double lower lung distribution more common; ground glass in 22 cases, common diffuse lungs; nodules in 10 cases, were multiple, both lung distribution , Diameter <3cm (including 7 cases of diameter <1cm), including two pulmonary diffuse miliary nodules in 3 cases; grid or line-like shadow in 4 cases, distributed in two lungs in 2 cases, widely distributed in Two leaves of two lungs. Different types of infection, bacterial infection in real variable shadow most common, followed by ground glass shadow; fungal infection consolidation shadow, ground glass shadow, nodules are more common. Conclusion CT is of great value in the diagnosis of pulmonary infection after liver transplantation.
