FIGURE 2.

A 71-year-old woman with a benign solitary fibrous tumor of the pleura manifesting as a nonspecific solitary pulmonary nodule. The enhanced chest CT transverse image of the mediastinal window at the basal segmental pulmonary arteries shows a 1.3 × 1.0 cm nonspecific solitary pulmonary nodule in the right middle lobe with a smooth margin and homogenous attenuation. On the follow-up CT after a year, the nodule showed interval growth with a 1.5 × 1.2 cm size and with the same CT characteristics (not shown). The whole-body ¹⁸F-fluorodeoxyglucose positron emission tomography CT transverse image shows mild hypermetabolism (maxSUV: 1.8) (not shown).
