Note: This case has been tagged as "legacy" as it no longer meets image preparation and/or other case publication guidelines.
Juxta-articular osteopaenia involving tarsals, metatarsals and phalanges.
Multifocal areas of bone resorption involving multiple tarsals, metatarsals, phalanges as well as distal end of tibia and fibula.
Coronal view shows multifocal areas of predominantly well-defined abnormal marrow signal appearing hypointense on T1WI.
On the axial images there are multifocal areas of predominantly well-defined hyperintense signal on STIR. Subtle enhancement of a few of the bony lesions and area of extra-osseous soft tissue component (arrow) on post contrast T1 fat saturated image.
CT-guided biopsy reveal diffuse large B-cell lymphoma.
Patchy dense tumor infiltrates with severe crushing artefact of the marrow. Morphological details are lost. The diagnosis of B cell lymphoma is based on strong CD20 and CD45 staining of a dense crushed lymphoid infiltrate.

The radiological appearance of bone lymphoma is variable and nonspecific, varying from focal lytic lesions with geographic margins to mixed sclerotic/lytic lesions or diffuse permeative processes.
