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。
Objective To analyze the imaging findings of primary bone lymphoma (PBL) and to improve the understanding of the disease. Methods Twenty patients with PBL confirmed by biopsy and pathology were collected and their imaging features were retrospectively analyzed. Results In 20 cases, there were 6 cases of femur, 4 cases of skull, 3 cases of tibia, 3 cases of spine, 1 case of clavicle, humerus, sacrum and ilium. According to the characteristics of bone destruction, there are 11 cases of infiltration, 7 cases of osteolytic, 1 case of osteoid sclerosis and 1 case of mixed type, of which 3 cases were complicated with pathological fracture. 19 cases had obvious soft tissue mass, CT examination of 13 cases of soft tissue mass density slightly lower than the adjacent muscle tissue, no necrosis and calcification; MRI examination in 9 cases, T1WI lesions were slightly lower signal, including 5 cases in the T2WI Performance was slightly higher signal, 4 cases of non-uniform signal, enhanced significantly enhanced. Conclusion PBL imaging has certain characteristics: often accompanied by obvious soft tissue mass, clinical symptoms are relatively mild, the destruction of the infiltration of bone type, osteolytic type, enhanced significantly enhanced.
