In patients with pulmonary sarcoidosis, air trapping as evidenced by expiratory high-resolution computed tomography (HRCT) is not specific for a given stage of disease. Air trapping can occur at the level of the secondary lobule, as well as in distributions suggesting sublobular, subsegmental, and segmental involvement. While air trapping can be a nonspecific finding, it is a common feature in patients with pulmonary sarcoidosis and is a supportive diagnostic finding.
在肺结节病患者中，呼气期高分辨率计算机断层扫描（HRCT）显示的空气潴留对疾病的特定阶段并不具有特异性。空气潴留可发生在次级肺小叶水平，也可呈提示小叶下、亚段和段受累的分布。虽然空气潴留可能是一个非特异性表现，但它是肺结节病患者的常见特征，也是一个支持性诊断依据。
