摘　　要：目的：探讨骨淋巴瘤的影像学表现及诊断价值。方法回顾性分析25例经病理证实的骨恶性淋巴瘤患者的影像学表现，其中原发性骨淋巴瘤6例，继发性骨淋巴瘤19例。25例均行 X 线及 CT 检查，其中12例行MR 检查，3例行 SPECT 检查。结果 X 线、CT 表现为骨质破坏溶骨型7例，浸润型11例，骨质硬化型2例，混合型5例。12例 MR 检查，10例 T1WI 信号呈等或低信号，T2WI 呈等或稍高信号，以 T2WI 脂肪抑制序列显示最为清楚，呈中、高信号。T1WI 及 T2WI 均呈低信号2例。病灶周围出现软组织肿块者13例，增强扫描后呈中度均匀或不均匀强化。3例全身骨显影中均表现为病变处放射性浓聚灶。结论综合分析 X 线、CT、MR 及骨显影的影像学表现，对骨淋巴瘤诊断颇具价值。Objective To investigate the image manifestations and diagnostic value of bone lym-phoma. Methods The imaging findings of 25 patients with bone malignant lymphoma confirmed by pa-thology were retrospectively analyzed,which including 6 cases of primary lymphoma of bone and 19 cases of secondary lymphoma infiltration of bone. Twenty-five cases underwent X-ray and CT examination, 12 cases underwent MR examination,3 cases underwent SPECT examination. Results X-ray and CT findings showed：lesions were osteolytic in 7 cases,infiltrative in 11 cases,sclerotic in 2 cases and mixed in 5 cases. Twelve cases of MR imaging showed that,10 cases were equal or low signal intense on T1WI, equal or slightly hyperintense on T2WI,moderate to hyperintense on fat suppression T2WI. Two cases were low signal intense on T1WI and T2WI. The soft tissue masses around the lesions in 13 cases were seen with moderate uniform or non-uniform enhancement after injection of contrast medium. Whole-body bone SPECT showed local uptake lesions in 3 cases. Conclusions Imaging features of X-ray,CT,MR and nuclear medicine are helpful for the diagnosis of bone lymphoma.
