摘　　要：目的分析骨原发性淋巴瘤的MRI及CT表现。方法选取医院30例原发性骨淋巴瘤患者,其中17例接受MRI及CT检查,13例仅接受MRI检查,观察并分析两种检查的成像特点。结果CT诊断率为(70.0%),其中肱骨4例、股骨5例、胫骨3例、胸椎3例、腰椎1例、髂骨2例、骶骨1例,2例病变累及多骨。MRI诊断率为(73.33%),其中肱骨3例、股骨6例、胫骨3例、胸椎2例、腰椎2例、髂骨1例、骶骨1例,4例病变累及多骨。骨质破坏特征为溶骨性、有骨质硬化反应、轻度骨膜反应、软组织肿块及病理性骨折。结论PLB术前诊断困难,MRI与CT可显示影像学特征,两者相互结合有助于提高影像学检查的特异性。Objective To analyze the MRI and CT features of primary bone lymphoma.Methods A total of 30 patients with primary bone lymphoma in our hospital were selected.Among them,17 cases received MRI and CT examination,and 13 cases only received MRI examination.Results The diagnostic rate of CT was 70.0%,including 4 cases of humerus,5 cases of femur,3 cases of tibia,3 cases of thoracic vertebrae,1 case of lumbar vertebrae,2 cases of ilium and 1 case of sacrum.The diagnostic rate of MRI was 73.33%,including 3 cases of humerus,6 cases of femur,3 cases of tibia,2 cases of thoracic vertebrae,2 cases of lumbar vertebrae,1 case of ilium and 1 case of sacrum.4 cases involved multiple bones.Bone destruction was characterized by osteolysis,osteosclerosis,mild periosteal reaction,soft tissue mass and pathological fracture.Conclusion It is difficult to diagnose PLB preoperatively.MRI and CT can demonstrate the imaging features of PLB,and the combination of MRI and CT helps to improve the specificity of imaging examination.
