Abstract

A 60-year-old man visited our hospital because of the incidentally found mass of the rib on chest radiography. Chest X-ray showed expansile bony hypertrophy on left 5th rib and bone setting of the computed tomography scan of chest revealed 4.2x2.5 cm sized, elongated bony expansion with geographic radiolucent lesion in the medullary cavity and cortical thinning. Technetium-99m bone scintigraphy showed diffusely increased radioactivity along the left 5th rib. We present this case to discuss about a possible differential diagnosis in this type of lesion.
