 | Media file 1: Photomicrograph of bone involved with late-stage Paget disease demonstrates intersecting remodeling lines forming a mosaic pattern. |
 | Media file 2: Lateral radiograph of the tibia in a patient with Paget sarcoma reveals a destructive bone-forming mass in the proximal tibia (osteosarcoma). |
 | Media file 3: Anteroposterior radiograph of the hip in a patient with Paget disease demonstrates dense sclerosis involving the femoral head and neck (arrows). This is a high-risk area for insufficiency fracture. |
 | Media file 4: Anteroposterior radiograph of the femur in a patient with late-stage Paget disease reveals a transverse insufficiency fracture through the proximal femoral shaft (banana fracture). |
 | Media file 5: Lateral skull radiograph in a patient with Paget disease demonstrates a large, well-circumscribed lytic lesion (arrows) in the frontal and parietal bones (osteoporosis circumscripta). |
 | Media file 6: Lateral radiograph of the calvarium in a patient with Paget disease reveals multiple patches of sclerotic bone in the calvarium (cotton wool appearance). |
 | Media file 7: Lateral radiograph of the lumbar spine in a patient with Paget disease demonstrates enlargement of an involved vertebral body (arrow), with sclerosis more prominent at the vertebral endplates (picture frame vertebra). |
 | Media file 8: Lateral radiograph of the upper thoracic spine reveals a densely sclerotic vertebral body (ivory vertebra) caused by Paget disease (arrow). The appearance mimics findings that can be observed with malignant neoplasm such as lymphoma or metastatic disease. |
 | Media file 9: Anteroposterior radiograph of the pelvis demonstrates thickening of the right iliopectineal line (small arrows), as well as later-stage involvement with Paget disease, including trabecular coarsening and patchy sclerosis (large arrow). |
 | Media file 10: Anteroposterior radiograph of the right hip, coned down on the obturator ring, reveals patchy sclerosis and disorganized coarsened trabecula characteristic of late-stage Paget disease. An insufficiency fracture of the ischium inferior to the acetabulum (arrows) is present. |
 | Media file 11: Coned down anteroposterior radiograph of the knee demonstrates an abnormal lucency in the distal femur with a flame-shaped or "blade of grass"-shaped proximal margin caused by the advancing lytic phase of Paget disease (black arrows). Courtesy of Lee F. Rogers. |
 | Media file 12: Lateral coned down radiograph of the tibia reveals replacement of the tibial tubercle with pagetic bone that has mixed osteolysis and sclerosis (arrows). |
 | Media file 13: Anteroposterior radiograph of the distal forearm demonstrates mixed-phase Paget disease in the distal radius with lytic disease proximally (white arrows) and coarsened trabeculae more distally (black arrow). |
 | Media file 14: Anteroposterior radiograph of the proximal femur involved with intermediate (mixed phase) Paget disease reveals characteristic insufficiency fractures on the convex surface of the bone (arrow). |
 | Media file 15: CT image of the first sacral vertebra demonstrates marked cortical thickening (arrows) and trabecular coarsening. Courtesy of Lee F. Rogers. |
 | Media file 16: Axial T1-weighted MRI of the knee in a patient with Paget disease reveals prominent dark lines in the medullary bone, indicating trabecular coarsening (arrows). Courtesy of Lee F. Rogers. |
 | Media file 17: Sagittal T1-weighted MRI of the lumbar spine demonstrates enlargement of the fourth lumbar vertebral body with no central canal encroachment (arrows). Courtesy of Lee F. Rogers. |
 | Media file 18: Whole-body bone scan in a patient with polyostotic Paget disease reveals intense uptake of radiopharmaceutical in the femur, pelvis, spine, and proximal right humerus. The cortical discontinuity of the proximal right humerus represents an insufficiency fracture (arrow). Courtesy of Lee F. Rogers. |
 | Media file 19: Anterior image of the thoracic and lumbar spine in a 75-year-old man demonstrates intense radiopharmaceutical uptake in the third lumbar vertebra, which is involved with Paget disease (arrows). Courtesy of Lee F. Rogers. |
