Endobronchial ultrasound appearance of pulmonary artery thrombus in a patient with thymic carcinoma.

A 27-year-old man presented with superior vena cava syndrome. Chest radiographs revealed a large mediastinal mass. He underwent mediastinoscopy at an outside institution, which revealed a poorly differentiated carcinoma consistent with thymic carcinoma. Staging procedures included an endobronchial ultrasound transbronchial needle aspiration, which confirmed cancer spread to right hilar (11R), subcarinal (7), and right lower paratracheal (4R) lymph node stations. A right pulmonary artery thrombus (Figure 1) was also identified on endobronchial ultrasound transbronchial needle aspiration and confirmed by computed tomographic imaging (Figure 2).
