摘要
目的：观察淋巴瘤浅表肿大淋巴结的超声声像图特征,探讨其超声诊断价值。方法：分析34例淋巴瘤病人48个受累浅表肿大淋巴结声像图,并选择36例病人45个良性反应性增生肿大淋巴结做对比。比较两组淋巴结长径与短径（L/S）的比值、淋巴门髓质部形态,血流灌注类型、血管数目、分布及其血流分级,并比较两组病人浅表肿大淋巴结分布部位数。结果：淋巴瘤组淋巴结常多处肿大,多数呈类圆形（L/S〈2）,淋巴门髓质消失,被淋巴瘤侵入的淋巴结呈高灌注,在中心及周边均可有彩色血流显示,血管外形多粗细不均、杂乱,分支多,走行移位、扭曲,血流分级Ⅱ~Ⅲ级。良性肿大淋巴结所显示的血管外形多粗细均匀、平直,分支少,走行规则、对称,血流分级0~Ⅱ级。结论：超声对淋巴瘤引起的浅表肿大淋巴结有较高的诊断价值。
Objective：To investigate the sonographic characteristics of superficial lymphadenopathy in lymphoma and evaluate the diagnostic value of sonography.Methods：The sonograms of 34 lymphoma cases with 48 superficial lymph nodes were reviewed and compared with 36 cases with 45 benign reactive hypertrophic ones.The characteristics between two groups were compared the sites,the long-to-short ratio（L/S）、the echogenic of hilus、peripheral blood perfusion types,distribution,and the number of blood vessels and the gradation of blood flow were observed with PDI.Results： Most of the lymphomatous lymph nodes were nearly round,Absent of hilus,and usually in multilocations.The lymph nodes were invaded by lymphoma exhibited high perfusion,and there are colorful blood flow in center and peripheral.The blood distribution of lymphoma nodes exhibited malposition,deformation disorder and distortion with II to III grade blood flow.The blood flow in benign enlarged lymph nodes exhibited in regular shape,and its blood grade was 0 to II.Conclusion：Sonography is valuable for the evaluation of superficial lymphadenopathy in lymphoma.
