摘要

背景:尽管RT-PCR检测通常被认为是诊断SARS-CoV-2的金标准,但它们并非没有缺陷,检测到感染的可能性取决于进行检测的时间。由于陷阱不同,存在假阴性的可能性。因此,COVID-19流行期间疑似患者的影像学特征、生化检查异常与症状的相关性是必要的。病例介绍:在此,我们报告一名42岁男性患者,表现为高热、干咳、头痛和头晕。他进行了两次RT-PCR检测,结果均为阴性。胸部x光片显示双肺混浊,转到肿瘤医院做肺癌筛查。患者接受了胸部hrct和实验室检查以进一步评估,并被确定为典型的COVID-19症状。结论:胸部HRCT表现典型且实验室检查结果异常的临床症状患者,即使两次RT-PCR检测均为阴性,也应考虑为COVID-19患者进行隔离治疗。

Patient with false negative RT-PCR for COVID-19 referred to cancer hospital for lung cancer screening: A case report
Background: Even though RT-PCR tests are generally considered the gold standard for diagnosing SARS-CoV-2, they are not without flaws, and the likelihood of detecting an infection varies depending on when the test is performed. There is chance of false negative due to different pitfalls. So there is essential of correlation of radiological characteristics, abnormalities in biochemical tests and symptoms of suspected patient during COVID-19 epidemic. Case presentation: Herein, we report a 42-year-old male patient with high-grade fever, dry cough, headache and dizziness. He went for the RT-PCR test two times and reported negative. On the chest X-Ray, there was opacity on both lungs and referred to cancer-hospital for lung-cancer screening. The patient underwent chest-HRCT and laboratory tests for further evaluation and was identified as typical COVID-19 findings. Then the patient was isolated and treatment of given according to COVID-19 treatment guidelines   Conclusion: It is concluded that a clinically symptomatic patient with typical chest HRCT and abnormal lab findings for COVID-19 should be considered as a COVID-19 patient and isolated even with two negative RT-PCR tests.
