摘　　要：目的探讨骨原发性非霍奇金淋巴瘤影像表现及诊断价值。方法回顾性分析16例经手术病理证实的骨原发性非霍奇金淋巴瘤。16例患者均行相应部位X线检查,8例行CT检查,4例行MRI检查。结果16例中病变位于肋骨、髂骨、胫骨、跟骨各1例,肱骨2例,股骨5例,脊椎5例,4例合并病理性骨折。X线及CT表现为浸润型5例,溶骨型6例,囊状膨胀型1例,混合型4例。MRI检查4例均为椎体淋巴瘤,表现为T1WI呈等或稍低信号,T2WI呈等或稍高信号,增强扫描呈轻至中度强化。结论长骨及脊椎为本病好发部位,影像表现以浸润型和溶骨型多见,骨质破坏范围相对较小而软组织肿块较大为特点,CT对本病的骨质改变和骨膜反应等观察优于X线。MRI对早期骨质改变和软组织侵犯的显示优于X线和CT。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 eases 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）,femur（5 cases） and vertebrae（5 cases）, 4 cases with pathological fracture. The CT and X-ray showed 5 cases were int＇dtrating 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,sIighfly hypefintense or homogeneous on T2WI,slighyly or moderate enhancement in contrast enhancement. Conclusion Compared with X- ray,CT can more dearly 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.
