Abstract Objective: To study the MRI findings of primary lymphoma of bone(PLB) and evaluate MRI scanning in the diagnosis of the disease. Methods: A retrospective analysis was made on imaging of 8 patients with pathologically proved PLB. The unenhanced and enhanced scanning was performed in all patients. Results: There was single bone involvement in 7 cases and multiple involvement in 1 case. Seven cases were B-lymphocytes, while 1 case was T-lymphocytes. Most of the lesions showed iso- or hypo-intense signal on T1WI and iso- or slightly hyperintense signal on T2WI. Lesions showed significantly homogeneous or inhomogeneous enhancement. Various size soft-tissue masses were present in all cases. Conclusion: PLB mainly involved vertebrae and pelvis. There was single bone involvement in most cases of PLB. The comparatively typical features of MRI were a large accompanying soft tissue mass, slight periosteal reaction, and isointensity on T2WI with significantly enhancement. The plain and enhanced MRI scanning were all very helpful in the diagnosing of PLB.
