Fig. 4From: The value of transthoracic echocardiography in the detection of extra-cardiac lesionsMiddle mediastinal mass (pericardial cyst) in a 41-year-old woman. A and B TTE showed a well-circumscribed anechoic mass between the heart and the liver. C and D Contrast-enhanced CT showed a regularly shaped mass with the cystic hypodensity and no enhancement. E The pathologic diagnosis of this mass was pericardial cyst. The wall of the cyst was lined with cuboidal epithelium, and the cavity was filled with clear cystic fluid.
