5例新型冠状病毒肺炎患者的胸部HRCT表现

Diagnosis of 5 cases COVID-19 with chest HRCT imaging

目的分析新型冠状病毒肺炎患者的胸部高分辨CT(HRCT)表现,探讨其诊断价值。方法回顾性分析新疆医科大学第一附属医院收治的5例确诊新型冠状病毒肺炎(COVID-19)患者的临床和影像资料。结果5例患者胸部影像均有异常发现,3例HRCT表现为肺野外带磨玻璃样密度影,累及一叶或多叶,呈楔形或扇形分布,且分布在肺野外带胸膜下,病变内可见血管增粗和由小叶间隔增厚所致的“铺路石”征;1例表现为右肺上叶胸膜下边缘模糊的小结节,另外1例表现为右肺中叶外带磨玻璃样密度影。结论COVID-19患者胸部HRCT表现具有一定的特点,但诊断尚需要结合临床病史和核酸检测结果确定。

ObjectiveTo analyze the Chest High Resolution CT(HRCT)imaging of COVID-19,and to evaluate its value for diagnosis.MethodsA retrospective analyses were performed for 5 patients suffered with COVID-19 and diagnosis was confirmed by positive coronavirus nucleic acid detection.ResultsThe chest imaging of 5 patients were abnormal.Among them 3 patients showed multiple ground glass opacity(GGO)density lesions,which appeared as sort of lobular,wedge or fan in shape,distributing in lung parenchymal near pleural,inside those lesions there were thickened vascular and“paving stones sign”which caused by thickening of interlobular/interlobular septa;One case presented with sub-pleural single unclear margin nodule in the right upper lobe while another one with a subtle patch-like GGO lesion in the peripheral zone of right middle lobe.ConclusionThere were certain imaging feature of COVID-19 on chest HRCT,which will play an important role in clinical,yet confirmed diagnosis should be made by comprehensive consideration of imaging,epidemic history and nucleic acid test.
