摘　　要：目的分析成人乙型流感病毒肺炎患者的临床特点及影像学特征,提高临床医师对乙型流感病毒肺炎的认识。方法收集2021年1月至2022年12月在首都医科大学附属北京中医医院发热门诊临床诊断的成人乙型流感病毒肺炎患者的临床资料。对患者的临床症状、血常规结果及肺部CT结果进行分析总结。结果共收集到24例成人乙型流感病毒肺炎患者的临床资料。发病至就诊时间(2.7±0.3)d。全部患者均有发热,其中14例体温>39℃。血常规及降钙素原水平正常,而C反应蛋白水平升高[(56.28±32.35)mg/L]。氧饱和度均正常(≥95%)。肺部CT多表现为单侧分布的小片状磨玻璃密影,部分表现为间质性病变导致的条索状影。结论乙型流感病毒感染也可导致肺炎,但较为局限,预后较好。Objective To analyze the clinical and imaging characteristics of adult patients with influenza B viral pneumonia and improve the understanding of influenza B viral pneumonia in clinicians.Methods The clinical data of adult patients with influenza B virus pneumonia were collected from January 2021 to December 2022 in the fever clinic of Beijing Hospital of Traditional Chinese Medicine affiliated to Capital Medical University.The clinical symptoms,blood routine results and lung computed tomography(CT)results were analyzed and summarized.Results The clinical data of 24 adult patients with influenza B virus pneumonia were collected.The time from onset to treatment was(2.7±0.3)d.All patients had fever,and 14 of them had body temperature>39℃.Blood routine and procalcitonin levels were normal,while C-reactive protein levels were elevated[(56.28±32.35)mg/L].Oxygen saturation was normal(≥95%).The pulmonary CT findings were mostly small flake ground glass shadows distributed on one side,and some of them were cord shadows caused by interstitial lesions.Conclusions Influenza B virus infection can also cause pneumonia,but is relatively limited and has a good prognosis.
