Endoscopic ultrasonography in pulmonary tuberculosis

Endoscopic ultrasonography (EUS) has become a well-established modality in the evaluation of mediastinal and abdominal lesions. Several case reports have shown EUS to be effective in the evaluation of extrapulmonary tuberculosis. However, no report on EUS evaluation of pulmonary tuberculosis exists in current literature. In this case report, we present a patient with a parenchymal lung abnormality incidentally discovered on EUS and later diagnosed as pulmonary tuberculosis. We believe this case demonstrates a feasible role of EUS in the diagnosis of solid TB lesions within mediastinum and/or central and superior lung parenchyma. Furthermore, we would suggest that the addition of fine needle aspiration might produce a high diagnostic yield with minimal patient discomfort.
