武汉儿童医院为一例首发症状为急性阑尾炎的隐匿新型冠状病毒肺炎患儿进行了急诊腹腔镜阑尾切除术。术后肺部CT所示：右肺下叶背段见一类圆形致密影，边缘略呈磨玻璃样改变。咽拭子2019新型冠状病毒(SARS-CoV-2)核酸检测呈阳性，COVID -19诊断成立。患儿发病前与确诊为COVID -19的祖母密切接触，提示家庭内传播是儿童2019-nCoV感染的重要传播途径。本例患儿发病初期新型冠状病毒肺炎呼吸道症状不明显，早期以恶心、呕吐、腹痛为主。在疫情未结束之前，来自疫区或有接触史，涉及外科急症需要手术的患儿，术前肺部CT检查筛查新型冠状病毒肺炎非常必要。“,”Emergent laparoscopic appendectomy was performed for a boy of occult novel coronavirus pneumonia with a presenting symptom of acute appendicitis at Wuhan Children’s Hospital. Postoperative lung computed tomography (CT) indicated a round dense shadow with slightly ground-glass-like margins in the dorsal segment of right lower lung. Pharyngeal swab nucleic acid test was positive for 2019-nCoV and thus a definite diagnosis of COVID -19 was made. Prior to the onset , he had close contacts with his grandmother with a definite diagnosis of COVID -19. It proved that intra-family transmission was an important transmission route for pediatric 2019-nCoV infection. In this case, the respiratory symptoms of COVID -19 were not obvious during an early stage. The major symptoms were nausea, vomiting and abdominal pain. For individuals coming from the epidemic area, with a history of exposure and developing acute surgical conditions, preoperative pulmonary CT scan is necessary for screening COVID -19.
