摘　　要：目的分析原发性骨淋巴瘤(PBL)的影像学表现,提高对该病的认识。方法搜集经活检及手术病理证实的PBL患者20例,回顾性分析其影像学特点。结果 20例中,股骨6例、颅骨4例、胫骨3例、脊柱3例、锁骨、肱骨、骶骨及髂骨各1例。根据骨质破坏特点,分为浸润型11例,溶骨型7例,骨质硬化型1例,混合型1例,其中3例合并病理性骨折。19例有较明显的软组织肿块,CT检查13例软组织肿块密度稍低于邻近肌肉组织,内无坏死及钙化;MRI检查9例,病灶T1WI上呈等、稍低信号,其中5例在T2WI上表现为稍高信号,4例为不均匀信号,增强后较明显强化。结论 PBL影像学有一定的特点:常伴有明显的软组织肿块,临床症状相对较轻,骨破坏以浸润型、溶骨型为主,增强后明显强化。To analyze the imaging characteristics of primary bone lymphoma （PBL） , and to deepen the understanding of it. Methods Totally 20 cases of PBL confirmed by biopsy and surgical pathology were included in the study. The imaging appearances were retrospectively discussed. Results Among 20 cases of PBL,there were 6 cases in femur, 4 cases in skull, 3 cases in tibia, 3 cases in vertebra, 1 case in clavicle, humerus, sacrum and ilium, respectively. According to the type of bone destruction, there were infiltrating destruction （ n = 11 ） , osteolysis （ n = 7） , osteosclerosis （ n = 1 ） , and mixed type （ n = 1 ）. 3 cases of pathologic fracture were demonstra- ted in these 20 cases. 19 cases had distinct soft tissue mass. The density of 13 cases on CT was little lower than that of peripheral muscle and they were without necrosis or calcification. Totally 9 cases on MRI, and the lesions were equal or slightly low signal on T1WI. Five ca- ses were higher signal and four cases were heterogeneous signal on T2WI. The leisions had obvious enhancement. Conclusion PBL had some characteristics. It often had distinct soft tissue mass, relatively mild clinical symptoms, bone destruction focus on the infiltrating and osteolysis type and usually had obvious enhancement.
