The request for CT (computed tomography) diagnostic in patients with suspected COVID-19 pneumonia has become part of the daily clinical routine. We reported a case of a 61-year-old patient with flu-like symptoms and a suspected COVID-19 pneumonia. After a negative PCR-test (polymerase chain reaction), a non-contrast enhanced CT was performed which revealed a suspicious hyperdensity in the left pulmonary artery and a pneumonia in the left lower lobe. A contrast enhanced CT confirmed a pulmonary embolism. An acute pulmonary embolism is a major complication and a main differential diagnosis of COVID-19. A hyperdense pulmonary artery sign (PAS) is a sensitive sign for a pulmonary embolism. Non-enhanced chest CT scans should be checked for hyperdense PAS in suspected of COVID-19 patients.
对疑似新型冠状病毒肺炎患者进行CT（计算机断层扫描）诊断的要求已成为日常临床工作的一部分。我们报告了一例61岁有流感样症状且疑似新型冠状病毒肺炎的患者。在聚合酶链反应（PCR）检测呈阴性后，进行了非增强CT检查，结果显示左肺动脉有可疑高密度影以及左下叶肺炎。增强CT证实为肺栓塞。急性肺栓塞是新型冠状病毒肺炎的主要并发症和主要鉴别诊断之一。肺动脉高密度征（PAS）是肺栓塞的一个敏感征象。对于疑似新型冠状病毒肺炎患者，应在非增强胸部CT扫描中检查是否存在肺动脉高密度征。
