Tracheal and bronchial diverticula are outpouchings arising from the trachea or bronchus. We present a case of a 35-year-old female who presented to the emergency department following a motor vehicle accident and was found to have multiple round, air-filled structures within the mediastinum on computed tomography of the thorax, concerning for pneumomediastinum. The patient had a negative fluoroscopic esophagography and subsequent imaging indicated tracheal and bronchial diverticula. While they are often asymptomatic and incidentally found, tracheal and bronchial diverticula may be misdiagnosed as pneumomediastinum, especially in the setting of blunt or penetrating trauma to the thorax.
气管和支气管憩室是起源于气管或支气管的囊袋状突出物。我们报告一例35岁女性病例，该患者在机动车事故后就诊于急诊科，胸部计算机断层扫描发现纵隔内有多个圆形、含气结构，怀疑为纵隔积气。患者食管荧光透视检查结果为阴性，后续影像学检查显示为气管和支气管憩室。虽然气管和支气管憩室通常无症状且为偶然发现，但它们可能被误诊为纵隔积气，尤其是在胸部受到钝性或穿透性创伤的情况下。
