Abstract

Abstract: We report a case of granulocyte colony-stimulating factor (G-CSF)–producing inflammatory myofibroblastic tumor of the pleura in a 71-year-old man. Contrast-enhanced CT demonstrated multiple pleural masses with pulmonary hilar lymph nodes swelling. 18 F-FDG PET/CT demonstrated marked focal FDG uptake in the thoracic masses with diffuse uptake in the bone marrow. Based on the pathological findings and elevated serum G-CSF level, the patient was diagnosed as G-CSF–producing inflammatory myofibroblastic tumor. Because G-CSF–producing tumors demonstrate aggressive clinical course, early and accurate diagnosis is important.
