Ultrasound diagnosis of a middle mediastinal mass

Abstract

of mediastinal masses. Ultrasound has played a very minor role in imaging masses in this location, being utilized only in very anterior lesions or those immediately adjacent to the chest wall.In lower mediastinal masses, however, ultrasound can be superior to CT, both in differentiating cystic from solid lesions and in demonstrating diaphragmatic relationships. In the following case, ultrasound played a major role in the diagnosis of a bronchogenic cyst of the lower middle mediastinum. FIGURE 1.

A case of mediastinal lymphangioma: endosonographic appearance

“…Ultrasonography can also be used to show mediastinal lesions adjacent to pleura and pericardium. Anechoic, thin-walled lesions may be diagnosed as benign cysts with the use of ultrasonography [9].…”
