The clinical and radiographic findings of four patients with multicentric giant cell tumor (GCT) of bone and Paget disease were retrospectively reviewed. Three patients underwent magnetic resonance (MR) imaging evaluation; all patients underwent computed tomography (CT). The MR characteristics of the bone component in pagetic GCT appeared to reflect the pagetic phase; a sclerotic pattern was largely represented by hypointense marrow signal intensity on images obtained with both long and short repetition times (TRs) and echo times (TEs). Conversely, a tumor appearing in a mixed pagetic phase demonstrated more heterogeneous signal intensity with all pulse sequences. Extensive soft-tissue components, noted in all cases, showed largely intermediate signal intensity on short TR/TE images and foci of increased signal intensity on longer TR/TE images. In most cases, dramatic reduction in tumor bulk was noted with the use of steroids alone. An awareness of this entity is important because the appearance of lytic lesions with soft-tissue extension in patients with Paget disease does not necessarily imply a grave prognosis. Serial CT or MR imaging is helpful in monitoring the remissions and exacerbations that reflect response to therapy in Paget disease and GCT.
