Abstract
CASE
A 68-year-old man with a history of unprovoked deep vein thrombosis (DVT) presented with recurrent knee effusions after the initiation of anticoagulation. Radiographs showed soft-tissue swelling without a distinct skeletal lesion. Magnetic resonance imaging, however, showed a marrow-replacing process in the distal femur. Subsequent biopsy demonstrated B-cell lymphoma.
CONCLUSION
This is a rare case of a primary lymphoma of bone mimicking synovial disease. It also highlights the fact that an unprovoked DVT may be a harbinger of an undiagnosed underlying malignancy.
