segment, and 21.7-mm-thick pleural effusion on the right side of the chest were detected. On PET-CT, the SUVmax values of the mass and nodule were 26.11 and 7.88, respectively. Minimal involvement of the pleural effusion (SUVmax: 2.11) was observed. Lesions with high uptake rates were observed at L3 and L4 vertebral bodies and the right iliac wing. Serosanguinous fluid taken by thora- centesis was exudative and cytology results were nonspe- cific. Transthoracic needle aspiration biopsy (TNA) was performed twice on the nodule in the right lung, but the pathology results were not diagnostic. Diffuse large B-cell lymphoma was diagnosed by tru-cut biopsy, and the patient was referred to the hematology clinic.PPL is equally common in men and women, with its incidence peaking during the 6th and 7th decades of life.[5,6] The ages of our patients are consistent with the literature. PPL is usually diagnosed late due to the non- specific clinical presentation and radiographic appear- ance. Patients are usually followed as a diagnosis of pneumonia, pulmonary tuberculosis, organizing pneumo- nia, or interstitial lung disease. Incisional or excisional biopsy is required for a definitive pathological diagno- sis.[7,8] There is no standard defined procedure for a diagnostic approach. The diagnostic value of bronchos- copy has been found to be relatively low.[9] Wang et al. recently reported the success rate of CT-guided core nee- dle biopsy in clinical diagnosis to be 84%. In this study, there was no difference in the diagnostic success rate
