Tracheomegaly is a medical condition where the tracheal diameter is greater than the upper limits of normal. Tracheomegaly can be classified as primary or secondary. Primary tracheomegaly is usually congenital. Secondary tracheomegaly can be due to multiple causes, including connective tissue disease, infections, autoimmune diseases like sarcoidosis, and prolonged mechanical ventilation. Here, we describe the first reported case of tracheomegaly secondary to coronavirus disease 2019 (COVID-19) pneumonia and COVID-induced interstitial lung disease (ILD). While many cases of tracheomegaly are asymptomatic, patients can have symptoms like cough, dyspnea, hemoptysis, or even respiratory failure. Tracheomegaly is associated with a higher risk of recurrent lower respiratory tract infections, chronic cough, bronchiectasis, and tracheobronchomalacia. Early recognition of COVID-19-induced tracheomegaly can help initial early management and reduce the incidence of infections.
气管扩大是一种气管直径大于正常上限的医学状况。气管扩大可分为原发性或继发性。原发性气管扩大通常是先天性的。继发性气管扩大可能由多种原因引起，包括结缔组织病、感染、结节病等自身免疫性疾病以及长期机械通气。在此，我们描述了首例报告的继发于2019冠状病毒病（COVID-19）肺炎和COVID诱导的间质性肺病（ILD）的气管扩大病例。虽然许多气管扩大病例无症状，但患者可能出现咳嗽、呼吸困难、咯血甚至呼吸衰竭等症状。气管扩大与下呼吸道反复感染、慢性咳嗽、支气管扩张和气管支气管软化的风险较高有关。早期识别COVID-19诱导的气管扩大有助于早期初步管理并降低感染发生率。
