Disseminated Primary Non - Hodgkin ’ s Lymphoma of Bone : A Case Re

for approximately 3% of primary malignant bone tumors and for 5% of extranodal lymphoma (1). In the majority of cases, the tumor involves the extremities and less frequently the axial skeleton. Disseminated malignant lymphoma is extremely rare, representing 0.8% of malignant non-Hodgkin’s lymphoma(NHL) (2). Here, we encountered primary NHL of bone involving the skull, spine, both upper and lower extremities and the pelvis without involvement of lymph nodes or other tissue. We report radiographic and MR findings of this case of pathologically proven NHL involving the whole skeleton and findings suggesting resolution of the lesion on follow-up radiography and MRI after chemotherapy.
