摘要

目的:探讨原发性骨淋巴瘤(Primary bone lymphoma,PBL)的影像表现特点。方法:回顾性分析经病理证实26例PBL患者的X线平片、CT和MRI表现。结果:26例中男14例,女12例,年龄20~73岁,平均(40.7±5.8)岁。26例中位于颅骨7例,股骨5例,肱骨4例,脊柱4例,锁骨2例,髂骨2例,胫骨1例,腓骨1例。X线和CT表现:溶骨型21例,混合型3例,硬化型1例,囊状型1例。伴病理性骨折3例,轻度骨膜反映3例,有较明显的软组织肿块21例。MRI检查7例:信号均匀3例,信号不均匀4例;病灶于T1WI上呈等、稍低信号,T2WI上呈稍高信号5例,呈等信号2例。增强扫描7例:肿瘤中度强化5例,显著强化1例,轻度强化1例。结论:PBL影像学有一定的特点,骨破坏多见于溶骨型,增强后以中度强化为主,常伴有明显的软组织肿块。

Abstract

Objective: To investigate the imaging characteristics of primary bone lymphoma(PBL). Methods: The X-ray, CT and MRI findings of 26 cases with pathology proven PBL were retrospectively analyzed. Results: Of 26 cases, 14 cases were male and 12 cases were female with a mean age (40.7±5.8) years(range 20 to 73 years). The lesions of PBL were located in the skull(n=7), the femur(n=5), the humerus(n=4), the spine(n=4), the collarbone(n=2), the ilium(n=2), the tibia(n=1), fibula(n=1) in 26 cases. The X-ray and CT findings: dissolved bone type(n=21), hybrid type(n=3), sclerosis type(n=1), cystic type(n=1). Three cases were with the pathological fracture, 3 cases with the slight periosteal reflect, and 21 cases with apparent mass lesion(n=21). MRI findings(n=7): the uniform signal (n=3), the nonuniform signal (n=4); the lesions in isosignal or slightly low signal on T1WI, the slightly high signal on T2WI(n=5), the isosignal(n=2). The enhanced scanning(n=7): the moderate strengthening(n=5), the significantly strengthen(n=1), mild strengthen(n=1). Conclusion: PBL imaging has certain characteristics, the bone destruction often appear in dissolved bone type, give priority to with moderate enhancement, often accompanied by obvious soft tissue mass.
