侵袭性肺曲霉菌感染MSCT特征及对预后的评价

目的观察侵袭性肺曲霉菌感染MSCT特征,探讨MSCT对其预后的评价价值。方法选择2011年2月-2015年10月间115例拟诊为侵袭性肺曲霉菌感染的患者为研究对象,均接受胸部MSCT检查,观察侵袭性肺曲霉菌感染的MSCT征象,比较血液病与非血液病患者侵袭性肺曲霉菌感染MSCT征象,并分析治愈好转组及恶化死亡组患者治疗0W、2W、4W及8W肺部病变形态学变化。结果在85例确诊的侵袭性肺曲霉菌感染中,MSCT共正确诊断81例,其MSCT表现包括斑片影、实变、团块影、结节、空洞、星月征、枝桠征及晕轮征,其中空洞例数最多,其次为结节、斑片影及晕轮征。病变以双侧多发为主,中下肺多见。与非血液病患者侵袭性肺曲霉菌感染MSCT征象比较,血液病患者斑片影、团块影、结节、空洞、星月征、枝桠征及晕轮征的比例均显著增高,组间比较差异具有统计学意义(P0.05)。治疗4W及8W,治愈好转组斑片影、结节及空洞病灶的比例均显著低于恶化死亡组,差异具有统计学意义(P0.05)。结论 MSCT能够准确显示侵袭性肺曲霉菌感染病灶的特征,具有很高的诊断准确率,并可以对患者预后进行评估。

MSCT Characteristics and Its Prognosis Value in Pulmonary Aspergillosis Invasion

Objective To observe the MSCT features of invasive pulmonary fungal infection, To evaluate the prognostic value of MSCT. Methods 115 cases diagnosed as invasive pulmonary aspergillosis patients from February 2011 to October 2015 were chosen as the research object, all underwent chest MSCT examination, To observe the MSCT findings of invasive pulmonary aspergillosis, Comparison of blood disease and blood disease of non invasive pulmonary aspergillosis MSCT signs, Analysis and cure group and death group of patients with deterioration of the changes of 0W, 2W, 4W and 8W in treatment of pulmonary lesion morphology. Results Invasive pulmonary aspergillosis in 85 cases of infection, 81 cases were diagnosed correctly by MSCT, The MSCT findings included patchy shadow, consolidation, mass, nodules or cavities, and branches of sign, sign and halo sign, The maximum number of empty, Followed by nodules, patchy shadow and halo sign. Lesions in the bilateral multiple, middle and lower lung. With the blood disease of non invasive pulmonary aspergillosis MSCT features, The blood spot disease shadow, mass, nodules or cavities, and sign, sign and halo sign is the proportion of branches were significantly increased, The differences between groups were statistically significant (P<0.05). The treatment of 4W and 8W, the cure group shadow plaques, nodules and lesions void ratio were significantly lower than the deterioration of the death group, The difference was statistically significant (P<0.05). Conclusion MSCT features of invasive pulmonary aspergillosis lesions accurately, Has a high diagnostic accuracy, It can evaluate the prognosis of patients.
