Left hilar lung cancer in a 51-year-old man. A and B TTE showed an irregularly shaped hyperechoic mass near the left hilum of the pulmonary artery bifurcation with left pulmonary artery and left pulmonary vein invasion. C Contrast-enhanced CT shows an irregularly shaped mass with mediastinal lymph node metastasis and obstructive atelectasis. D The pathologic diagnosis of this mass was moderately differentiated squamous cell carcinoma. TTE indicates transthoracic echocardiography; CT indicates computer tomograph; LA, left atrium; PA, pulmonary artery
