Objective To explore the imaging diagnosis of primary bone non-Hodgkin lymphoma.Methods Sixteen cases of bone non-Hodgkin lymphoma verified by pathology were analyzed retrospectively.16 cases were examined by X-ray,8 cases were also checked by CT and 4 cases examined by MRI.Results The lesions were located in the costal bone (1 case),iliac bone(1 case),tibia(1 case),calcaneus(1 case),humerus(2 cases),femu(r5 cases)and vertebrae(5 cases),4 cases with pathological fracture.The CT and X-ray showed 5 cases were infiltrating type,6 cases were osteolytic type,1 case was cystic expansion type,1 case was mixed-type.In 4 cases,MRI showed slightly hypointense or homogeneous on T1WI,slightly hyperintense or homogeneous on T2WI,slightly or moderate enhancement in contrast enhancement.Conclusion Compared with X-ray,CT can more clearly indentify the lesions such as destruction of bone,the sclerotic reaction.MRI can more clearly identify the lesions such as the early changes of bone mineral content invaded by lymphoma and the early involvement of bone marrow.
