(a) Pelvic radiograph of a patient with disseminated Hodgkin lymphoma showing faint increased sclerosis in the right femur intertrochanteric region (white arrowhead) with layered periosteal reaction in the right proximal femur metadiaphyseal region (white arrow). Note apparent normal appearance of the left proximal femur. (b) T1-weighted and (c) contrast-enhanced T1-weighted fat-saturated MR images showing multiple foci of T1 hypointense and enhancing marrow lesions (white arrows) in both femora. (d) Diffusely increased sclerosis of the vertebral body (white arrow) compared with adjacent normal vertebral body (black arrow) is described as ivory vertebrae in another patient with Hodgkin lymphoma.
