Paraseptal emphysema can be smoking-related but has other causes, including surfactant deficiency, COVID-19, and age. The typical acute chest tomographic findings of COVID-19 include bilateral ground-glass opacities with or without consolidation and interstitial thickening in a peripheral and posterior predominant distribution. Evolution of these findings can occur and ultimately lead to fibrosis. The development of bullae, pneumomediastinum, and pneumothorax can occur as complications of non-invasive or mechanical ventilation. This case report describes incidental paraseptal lucencies that mimicked paraseptal emphysema in a patient with acute hypoxemic respiratory failure secondary to COVID-19 without a prior history of smoking only requiring a high-flow nasal cannula.
间隔旁肺气肿可能与吸烟有关，但也有其他原因，包括表面活性剂缺乏、新冠病毒病（COVID-19）和年龄。COVID-19典型的急性胸部断层扫描表现包括双侧磨玻璃影，可伴有或不伴有实变，以及以周边和后部为主的间质增厚。这些表现可能会演变并最终导致肺纤维化。肺大疱、纵隔气肿和气胸的发生可能是非侵入性或机械通气的并发症。本病例报告描述了一名继发于COVID-19的急性低氧性呼吸衰竭患者出现的偶然间隔旁透亮区，该患者无吸烟史，仅需高流量鼻导管吸氧，这些透亮区酷似间隔旁肺气肿。
