F-18 FDG uptake in a malignant localized fibrous tumor of the pleura.
In the case presented here, FDG-PET was performed to evaluate the possibility of malignancy. High FDG accumulation, with a standardized uptake ratio (SUR) of 3.0, was noted in an upper nodular compartment of the mass that exhibited malignant features histopathologically. It was suggested that FDG-PET is helpful to know which parts of lesions are benign or malignant in patients with LFTP whose prognoses are usually difficult to predict.
