Paget disease affects 5% of the population older than 40 years. The incidence of malignant transformation ranges from 0,7% to 14 % and the most common histological type is osteosarcoma. This case describes a 75 year old male with polyostotic Paget’s disease and rare malignant degeneration in the right ulna whose histological type was malignant fibrous histiocytoma. The radionuclide scan with MDP Tc 99m showed a cold area which was associated with marked increase in MDP - Tc 99 M uptake throughout all of the other affected bones and the same was seen on the Tl 201 imaging. In oposite to a few reports in the literature , the authors showed marked Talio-201 uptake in Paget’s disease , wheter malignant degeneration is present or not.
