(A) Posteroanterior chest roentgenogram shows a round opacity (arrow) at the retrocardiac region of left lower zone. (B) Noncontrast, reformatted, coronal computed tomography (CT) images of the thorax show a well-defined mass along the medial aspect of the left hemidiaphragm at the lower lobe, with a slightly inhomogeneous and hypodense inner structure. (C) Contrast-enhanced CT series show a well-defined lesion along the posterior left hemidiaphragm with a thin enhancing capsule (arrow). No air or calcification is evident in the mass. (D) No fluorodeoxyglucose uptake can be seen in the positron emission tomography scan.
