Radiological manifestations of skeletal lymphoma.

Lymphoreticular neoplasms primarily arise in extraskeletal locations with skeletal involvement usually secondary to hematogenous spread or by direct invasion from surrounding involved lymph nodes or soft tissues. Primary lymphoma of bone is relatively rare in comparison. Lymphoma encompasses Hodgkin's and non-Hodgkin's disease, Burkitt's lymphoma, and mycosis fungoides. Skeletal disease may present with symptoms localized to the site of bone involvement, as an incidental finding on imaging for other reasons, or as part of the staging of the disease. It is important that the radiologist is cognizant of the many presentations of skeletal lymphoma. We present a review of the radiological imaging of skeletal lymphoma with conventional radiographs, computed tomography, scintigraphic studies, and magnetic resonance imaging.
