摘要
目的分析CT检查56例病毒性肺炎的情况,并就其CT特征及表现进行总结探讨。方法选择2018年1—12月在本院就诊的56例病毒性肺炎患者作为研究对象。所有患者均行CT检查,分析其CT影像资料,观察其特征及表现。结果经CT检查发现,56例患者均存在不同程度的双肺病变。其中14例双肺所有肺叶、肺段均受累,22例左肺叶上段受累,8例左肺叶下段受累,10例右肺叶上段受累,2例右肺叶下段受累。56例患者行CT观察到29例存在磨玻璃影、24例存在碎石征、11例存在小片状模糊影、8例为大片状实影、3例存在支气管气象、5例存在小结节影、5例存在胸膜下网状影、3例存在条索。56例患者中13例伴有胸腔积液,其中4例双侧胸腔均有积液,单侧胸腔积液9例;3例伴有气胸,其中左侧气胸1例、右侧气胸2例;11例发现纵隔淋巴结增大,其中3例直径超过1.5 cm、5例直径在1~1.5 cm、3例直径<1 cm;6例肺门增大的情况,表现为肺门密度增大、影增宽。结论病毒性肺炎主要以间质性病变为主,可不同程度累及肺实质,CT检查主要以磨玻璃影、碎石征为特征,病变分布无特异性,结合临床症状可进一步明确诊断。
Objective To analyze the CT examination of 56 cases of viral pneumonia,and summarize the CT characteristics and manifestations.Methods The study period was from January to December,2018.According to the retrospective analysis method,56 cases of viral pneumonia patients treated in our hospital during this period were taken as examples.All patients underwent CT examination,CT image data were analyzed,and their characteristics and manifestations were observed.Results CT examination showed that all the 56 patients had different degrees of double lung disease.Among them,14 patients had bilateral lung involvement in all lobes and segments,22 in upper left lobe involvement,8 in lower left lobe involvement,10 in upper right lobe involvement,and 2 in lower right lobe involvement.In 56 patients,CT observation showed that 29 patients had ground glass shadow,24 had detritus sign,11 had small patchy fuzzy shadow,8 had large patchy solid shadow,3 had bronchial meteorology,5 had small nodules shadow,5 had sub pleural reticular shadow,and 3 had cords.Among the 56 patients,13 had pleural effusion,including 4 bilateral pleural effusions and 9 unilateral pleural effusions.There were 3 patients with pneumothorax,including 1 patient with left pneumothorax and 2 patients with right pneumothorax.Mediastinal lymph node enlargement was found in 11 patients,the diameter of lymph node was more than 1.5 cm in 3 patients,5 patients had a lymph node diameter between 1 and 1.5 cm,and 3 patients had a lymph node diameter less than 1 cm.In 6 cases,pulmonary hilar enlargement was characterized by enlarged pulmonary hilar density and shadow.Conclusions Viral pneumonia is mainly resulted interstitial lesions,which may involve lung parenchyma to varying degrees.CT examination is mainly characterized by vitreous opacity and detritus sign,and the lesion distribution is not specific.Combined with clinical symptoms,further diagnosis could be made.
