目的:探讨病毒性肺炎影像表现及其病理基础。方法:从符合临床诊断标准的病毒感染的40例肺炎病例的肺部影像资料中分析病毒性肺炎的影像特征及病理基础。结果:这40例病毒感染的肺炎的X线平片及CT平扫影像资料中提取其具有特征性的影像特点,其具有纤维条索状密度增高影(34例)占80%,短条交织网状密度增高影(29例占70%),小结节影(30例占71%),间质性肺炎样改变(8例占20%),磨玻璃密度影(19例占48%),以肺实变为主的影像(7例占17%)。结论:病毒性肺炎主要以间质性炎症为主,较少在早期表现为肺实质性炎症,其与其他肺间质性病变鉴别缺乏特异性,因此应结合实验室检查及对病变进程及治疗中的影像资料结合临床进行回顾性复诊。
Objective: To investigate the imaging manifestations of viral pneumonia and its pathological basis. Methods: The imaging features and pathology of viral pneumonia were analyzed from the lung images of 40 cases of pneumonia in line with the clinical diagnostic criteria. Results: The characteristic features of X-ray plain film and CT plain film were obtained from 40 cases of virus-infected pneumonia. The results showed that the density of fiber-like cords increased to 80% (34 cases) Mesh density increased (29 cases accounted for 70%), small nodules (30 cases accounted for 71%), interstitial pneumonia-like changes (8 cases accounted for 20%), ground glass density (19 cases accounted for 48% , Mainly lung consolidation (7 cases accounted for 17%). Conclusions: The main types of viral pneumonia are interstitial inflammation, with less manifestation of pulmonary parenchymal inflammation in the early stage and lack of specificity in distinguishing other pulmonary interstitial lesions. Therefore, laboratory tests should be combined with the pathological progress and treatment The image data combined with clinical retrospective review.
