不同部位骨原发性非霍奇金淋巴瘤的影像表现对比分析

目的:对比分析发生于不同部位的骨原发性非霍奇金淋巴瘤(PNLB)的影像表现.方法:搜集经手术病理及免疫组化证实的25例PNLB患者,按照病变发生部位分为四肢骨组(13例)和躯干骨组(12例).对两组的患者发病年龄、骨质破坏类型、软组织肿块大小及包绕骨病变形式、MRI信号特点进行分析.结果:四肢骨组的患者发病年龄(中位年...

Comparative analysis of imaging findings of primary non-Hodgkin lymphoma of bone in different locations

Objective:The purpose of this study was to comparatively analyze the imaging features of primary non-Hodgkin lymphoma(PNLB)of bone in different locations.Methods:25 patients with primary non-Hodgkin lymphoma confirmed by pathology were included in this study from 2004 to 2005.According to the location,the cases were divided into two groups:limb bone group(13 cases)and trunk bone group(12 cases).The age,type of bone destruction,soft tissue mass,signal pattern of the two groups were analyzed.Results:The age of limb bone group(median age 44 yo)was younger than that of the trunk bone group(median age 54 yo).Single lesion was more common in the limb bone group(77%),and osteolytic bone destruction and mixed bone destruction was more common(46%,respectively).In the trunk bone group,osteolytic bone destruction was the main type of bone destruction(50%),and there was no significant difference between the two groups(P>0.05).Although the soft tissue mass was more common in the two groups(72%),the size of soft tissue mass in the limb bone group was larger with a surrounding growing pattern.MRI signal characteristics were not specific.Conclusion:In the limb bone group,patients with primary non Hodgkin's lymphoma of bone are relatively young;bone destruction was mainly osteolytic and mixed destruction;single lesion was more common,and the size of soft tissue mass was larger.While in the trunk bone group,the age was older;soft tissue mass was smaller with a surrounding growing pattern.
