FIGURE 3.

A 51-year-old man with a benign solitary fibrous tumor of the pleura manifesting as a mediastinal tumor. This patient had underlying hepatocellular carcinoma. The enhanced chest CT transverse at the diaphragm level image of the mediastinal window shows a 2.8 cm paraesophageal mass with a smooth margin and heterogenous attenuation in the posterior mediastinum, mimicking metastatic lymphadenopathy or a neurogenic tumor. The whole-body ¹⁸F-fluorodeoxyglucose positron emission tomography CT transverse image shows no hypermetabolism in the tumor (not shown).
