This study retrospectively evaluated 213 patients. We excluded patients in the final analysis who did not meet criteria for any of the 3 clinical radiographic findings: patients with isolated mediastinal lymphadenopathy (LAD), adenopathy associated with a suspicious nodule or mass, and adenopathy associated with other radiographic findings consistent with sarcoidosis. The final analysis includes patients diagnosed by bronchoscopy with solid-organ malignancy, sarcoidosis, or lymphoma.
