Transbronchial Needle Aspiration in the Diagnosis of Intrathoracic Lymphadenopathy

Abstract

We conclude that TBNA, using 19-gauge histologic needles through a flexible bronchoscope, is a valuable tool in the diagnosis of intrathroracic adenopathy, particularly in patients with tuberculosis and sarcoidosis. TBNA should be considered in the diagnosis of intrathoracic adenopathy before other invasive procedures.
