摘　　要：目的探讨原发性骨淋巴瘤(PBL)的多影像学表现及其特征。方法经穿刺或手术病理证实原发性骨淋巴瘤22例,回顾性分析其X线、CT及MRI特点。结果本病多见于长管状骨干骺端或骨盆,椎体次之,22例中发生于股骨6例、骨盆5例、椎体3例,肱骨、胫骨及颅骨各2例,肩胛骨及肋骨各1例。X线平片、CT扫描对病变的大小、骨破坏边界显示效果较好,MRI对观察骨髓及骨旁软组织受侵的准确性极高。结论 X线平片、CT及MRI对诊断该病均具有一定的影像特征,各种检查方法各有其优缺点,应结合多种影像检查以增加病变显示信息量,提高正确诊断率。Objective To evaluate the multiple imaging manifestations and characteristics of primary bone lymphoma （PBL）. Methods Retrospective analysis was done by means of studying X-ray plain film, computerized tomography （CT） and magnetic resonance imaging （MRI） features in 22 cases of PBL that had been confirmed by biopsy or surgical pathology. Results The lesion occurred mostly in the metaphysis of long bone or in pelvis, and second to it was in vertebra. Of the 22 cases, those with PBL in fe- mur, pelvis and vertebral body accounted respectively for 6, 5 and 3. The number of the cases with PBL in humerus, tibia and skull was 2, and that in scapula and rib was 1, respectively. X-ray plain film and CT had good findings in showing the boundary ot lesion area and the extent of bone destruction, and MRI was good at showing the lesions of bone marrow involvement, as well as the involved soft tissue adjacent to bone. Conclusion X-ray plain film, CT and MRI for diagnosis of the disease have a certain image features, but all kinds of examination method has both advantages and disadvantages, multiple imaging examination should be com- bined to increase lesion information quantity.
