RESUMEN
ABSTRACT: A 27-year-old man, with a history of non-Hodgkin lymphoma 8 years ago, was admitted due to 9 months of persistent sternal pain. Chest CT revealed a mass in the sternum. 18 F-FDG PET/CT was performed, demonstrating a radioactive accumulation mass in the sternum, accompanied by massive osteogenesis and osteolysis. Histological and immunohistochemical analysis of ultrasound-guided fine-needle aspiration biopsy samples confirmed the diagnosis of aggressive osteoblastoma. We present a rare case of aggressive sternal osteoblastoma, instead of lymphoma recurrence, on 18 F-FDG PET/CT in an adult with history of lymphoma.
