北京协和医院普通型新型冠状病毒肺炎患者的初诊临床特征及CT影像学表现

目的初步探讨北京协和医院新型冠状病毒肺炎(COVID-19)初诊患者的临床特征及CT影像学表现。方法回顾性分析北京协和医院收治的13例2019-nCoV核酸检测阳性的COVID-19患者的流行病学史、临床特征、实验室检查及胸部CT影像学表现,对肺部CT异常病灶的部位、分布、密度及其他伴随征象进行分析,并综合判断患者的临床分型。结果 13例患者临床分型均为普通型,平均年龄为(46.8±14.7)岁(27～68)岁。10例有武汉接触史,2例有近期旅行史,1例有北京郊区出游史。92.3%(12/13)患者白细胞总数正常或降低,15.4%(2/13)患者淋巴细胞数降低。92.3%(12/13)患者发热,11例因发热就诊,2例(15.4%)表现为低热;8例(61.5%)有干咳。13例患者胸部CT均有异常,病变主要沿支气管束及胸膜下分布为主,8例病变相对局限(1～3个肺叶受累)、累及右下叶或左下叶多见,5例为双肺弥漫多发病变。10例(76.9%)患者胸部CT以磨玻璃影表现为主,7例(53.8%)部分磨玻璃影合并局灶实变影,10例(76.9%)病变内见血管束穿行、增粗,12例(92.3%)有支气管壁...

Preliminary Study on Clinical Features and CT Findings of Common-type Coronavirus Disease 2019 Patients in Peking Union Medical College Hospital

Objective To summarize the clinical characteristics and chest CT findings of coronavirus disease 2019(COVID-19)patients in Peking Union Medical College Hospital(PUMCH). Methods A total of 13 patients with COVID-19 confirmed at PUMCH from January 20 to February 6,2020 were selected as the research subjects.Their epidemiological histories,clinical characteristics,laboratory tests,and chest CT findings were analyzed retrospectively.The location,distribution,density,and other accompanying signs of abnormal lung CT lesions were recorded,and the clinical types of these patients were assessed. Results The clinical type was “common type” in all these 13 patients aged(46.8±14.7)years(range:27-68 years).Ten patients had a travel history to Wuhan or direct contact with patients from Wuhan,2 cases had recent travel histories,and 1 case had a travel history to Beijing suburb.The white blood cell(WBC)count was normal or decreased in 92.3% of the patients and the lymphocyte count decreased in 15.4% of the patients.Twelve patients(92.3%)had a fever,among whom 11 patients were admitted due to fever and 2 patients(15.4%)had low fever.Eight patients(61.5%)had dry cough.The CT findings in these 13 patients were all abnormal.The lesions were mainly distributed along the bronchi and under the pleura.The lesions were relatively limited in 8 patients(affecting 1-3 lobes,predominantly in the right or left lower lobe),and diffuse multiple lesions of bilateral lungs were seen in 5 patients.The CT findings mainly included ground glass opacities(GGOs)(n=10,76.9%),focal consolidation within GGOs(n=7,53.8%),thickened vascular bundle passing through the lesions(n=10,76.9%),bronchial wall thickening(n=12,92.3%),air bronchogram(n=10,76.9%),vacuole signs in the lesions(n=7,53.8%),fine reticulation and interlobular septal thickening(n=3,23.1%),reversed halo-sign(n=2,15.4%),crazy-paving pattern(n=2,15.4%),and pleural effusion(n=2,15.4%).Conclusions Most of our patients diagnosed with COVID-19 at PUMCH had a travel history to Wuhan or direct contact with patients from Wuhan.The first symptoms of COVID-19 mainly include fever and dry cough,along with normal or reduced counts of WBC and lymphocytes.CT may reveal that the lesions distribute along the bronchi and under the pleura;they are typically localized GGOs in the early stage but can become multiple GGOs and infiltrative consolidation in both lungs in the advanced stage.Scattered vacuole signs may be visible inside the lesions in some patients.
