摘　　要：目的探讨原发性骨淋巴瘤(primary lymphoma of bone,PLB)相关影像表现特点,以提高对该病的诊断和鉴别诊断能力。方法回顾性分析经穿刺细胞学或手术病理证实的7例PLB患者的X线、CT及MRI影像表现。结果 7例患者2例单骨发病,5例多骨发病,最常累及股骨、髂骨,骨质破坏以浸润型为主,骨皮质可见T2WI高信号"肿瘤通道",周围软组织肿块多巨大,累及关节者,关节间隙保持正常。结论 PLB与其它恶性骨肿瘤鉴别困难,但具有以下特点:全身症状轻、溶骨型骨质破坏(尤其长骨远端)伴或不伴骨膜反应及骨皮质增厚、软组织肿块明显而骨质破坏轻微、病变有包绕关节趋势(关节间隙保持正常)。Objective To describe the imaging appearances of primary lymphoma of bone （PLB）, including conventional radiographic, CT and MR imaging features. Methods We retrospectively reviewed 7 cases of PLB proved by puncture cytology or pathology. Results These 7 cases included 2 patients with single destruction and 5 patients with primary multifocal osseous lymphoma. Common location was femur and ilium, meanwhile, common appearance was lyric lesion. Cortical bone appeared ＂tumor tunnel＂ , which revealed high SI in Tz weighted MR imaging. Soft-tissue masses were mostly unappropriate size associated with little cortical destruction. Extension across joints persisted in normal joint space. Conclusion PLB is difficult to differentiate from other osseous tumors, however there are some characters： subclinical, lyric destruction （espaeially diametaphysis of a long bone） with or without periosteal and endosteal reaction, unappropriate softtissue mass associated with little cortical destruction, extension across joints with normal joint space.
