Posterior mediastinal mass (esophageal cancer) in a 69-year-old man. A TTE showed a round hypoechoic or heterogeneous echo mass with hypoechoic periphery and irregular hyperechoic interior, similar to “pseudo kidney” shape. B and C Contrast-enhanced CT showed a regularly shaped mass with inhomogeneous low-density shadow, obvious inhomogeneous enhancement behind left atrium. The esophageal wall was diffusely and irregularly thickened, and the corresponding lumen was irregularly narrow. D The pathologic diagnosis of this mass was esophageal squamous cell carcinoma. TTE indicates transthoracic echocardiography; asterisks, mass; LA, left atrium
