Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a recently discovered coronavirus which has caused a global outbreak of severe pneumonia with complications leading to hypoxic respiratory failure, acute respiratory distress syndrome (ARDS), cytokine storm, disseminated intravascular coagulation (DIC), and even gastrointestinal symptoms. While ground-glass opacity (GGO) is a typical radiographic finding associated most frequently with COVID-19 pneumonia, other less commonly noted atypical radiographic lung features include isolated lobar or segmental consolidation without GGO, discrete small nodules (centrilobular, "tree-in-bud"), lung cavitation, and smooth interlobular septal thickening with pleural effusion. Pneumomediastinum in COVID-19 patients has rarely been reported. A finding of pneumopericardium is unusual too. This report discusses the case of a young male with COVID-19 pneumonia who was found to have both these features on computed tomographic (CT) scans of his chest on presentation.
严重急性呼吸综合征冠状病毒2（SARS-CoV-2）是一种最近发现的冠状病毒，它已在全球引发了严重肺炎的爆发，其并发症会导致低氧性呼吸衰竭、急性呼吸窘迫综合征（ARDS）、细胞因子风暴、弥散性血管内凝血（DIC），甚至胃肠道症状。虽然磨玻璃影（GGO）是与新型冠状病毒肺炎最常相关的典型影像学表现，但其他较少见的非典型肺部影像学特征包括无GGO的孤立性肺叶或肺段实变、散在小结节（小叶中心性、“树芽征”）、肺空洞形成以及伴有胸腔积液的光滑小叶间隔增厚。新型冠状病毒肺炎患者出现纵隔气肿的情况鲜有报道。心包积气的发现也不常见。本报告讨论了一名患有新型冠状病毒肺炎的年轻男性病例，其在就诊时胸部计算机断层扫描（CT）上发现了这两种特征。
