Objective To analyze the imaging features of primary lymphoma of bone(PLB) Methods 17 cases of PLB,proved by pathology,included 12 cases male,5 cases female(age range from7 to 80,the mean age 47.5).X-ray films and CT images were obtained in all 17 cases,MRI images in 12 cases.Results(1)Location:6 cases with the tumor were found in femur,3 cases in ilium and thoracic spine respectively,2 cases in tibin,humerus and lumbar spine respectively,1 case in sacrum and sternum respectively(2)Number:in all 17 cases,only one case involved multiple bones,the other involved solitary bone.(3)Charactersistics:osteolytic destruction,sclerosis,light periosteous reaction,soft tissue masses and pathological fractures of vertebrae.Conclusion(1) PLB is lack of characteristic imaging features,so we should combine X-ray,CT and MRI images to observe lesions.(2)It is very difficult to differentiate PLB from other malignant tumors of bone.But slight clinical symptom of the whole body,small invasion or osteolysis with large soft tissue mass,slight periosteous reaction,all above can strongly imply the diagnosis of PLB.
