MRI of Paget's disease of bone

Abstract

Paget's disease is a relatively common condition in the elderly population and is not uncommonly seen as an incidental finding on imaging studies, including magnetic resonance imaging (MRI). It is important, therefore, for the radiologist to be aware of the MRI manifestations of the condition, so as not to mistake it for more sinister pathology. MRI can also be used to investigate the various complications of Paget's disease, particularly sarcomatous degeneration. This review describes the appearances of uncomplicated Paget's disease during its different pathological stages and in the setting of its various complications.
