title: Airways obstruction in patients with sarcoidosis: expiratory CT scan findings.
abstract: 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.
