摘　　要：目的探讨侵袭性肺部真菌感染(IPFI)CT表现特点。方法回顾性分析71例IPFI患者的CT检查资料和病历资料。观察三种主要CT表现在肺野内分布情况,比较不同免疫状态IPFI患者CT表现。结果 IPFI主要CT表现为结节或肿块、肺内实变影及磨玻璃影,病变以两肺分布为主(P<0.05),结节或肿块、肺内实变影下肺野分布率高于上肺野(P<0.05),肺野外周区域分布率高于肺野中央区域(P<0.05)。免疫抑制患者多发肺实变率高于免疫正常患者,而单发肺实变率低于免疫正常患者,胸腔积液发生率高于免疫正常患者,差异均有统计学意义(P<0.05)。结论 IPFI主要CT表现为结节或肿块、肺内实变影及磨玻璃影,而结节或肿块影以两肺下野及外周区域分布为主,不同免疫状态IPFI患者CT表现有所不同,多发肺内实变影常多见于免疫功能低下患者,而单发实变影则多见于免疫功能正常患者。Objective To investigate CT features of invasive pulmonary fungal infection （IPFI）. Methods CT examination data and medical records of 71 patients with IPFI were analyzed retrospectively. Observe three kinds of CT findings in pulmonary field distribution,and compare CT findings of different immune status in patients with IPFI. Results The most common CT findings of IPFI were nodules or masses, pulmonary consolidation and ground glass opacity in lungs, the lesions were located in two lung zones （P〈O.05）, the field distribution rate of pulmonary nodule or mass and pulmonary consolidation that were located in lower lung was higher than that in the upper lung （P〈0.05）, the distribution rate of lung peripheral region was higher than that of the central region （P〈0.05）. The rate of immunosuppressed patients with multiple pulmonary consolidation was higher than that of patients with normal immune, while the rate of immunosuppressed patients with solitary pulmonary consolidation was lower than that of patients with normal immune ,the incidence rate of pleural effusion was higher than that of patients with normal immune. There was significant difference （P〈0.05）. Conclusion The most common CT findings of IPFI are nodule or mass ,pulmonary consolidation and ground glass opacity in lung ,the nodules or masses are located in the lower and peripheral regions of both lungs, CT findings of patients with IPFI in different immune status is different, multiple pulmonary consolidation are seen most frequently in the patients with impaired immune, while more of solitary pulmonary consolidation can be seen in the patients with normal immune.
