【摘要】 目的　探讨浅表肿大淋巴结彩色多普勒血流显像的血流形态及分布特征鉴别浅表肿大淋巴结的性质。方法　前瞻性分析 81例患者的 95个淋巴结 ,其中反应增生性肿大淋巴结 1 6例 2 0个病灶 ,淋巴瘤 35例45个病灶 ,转移性淋巴结 30例 30个病灶。彩色多普勒血流显像观察上述病灶的血流形态并进行以下分型 :Ⅰ型 ,居中的门样血流并有规则的放射状分支 ;Ⅱ型 ,偏中心的门样血流伴或不伴不规则的放射状分支 ;Ⅲ型 ,包膜下环绕血流 (Ⅲa )、不规则网状血流 (Ⅲb)和多中心的门样血流 (Ⅲc) ;Ⅳ型 ,点状、短条状血流。结果　绝大多数( 85 .0 % )反应增生性淋巴结表现为Ⅰ型 ,少数为Ⅱ型 ( 1 0 .0 % ) ;淋巴瘤则表现为Ⅱ型 ( 33.3% )和Ⅲ型( 64.5 % ,其中 ,Ⅲa 2 8.9% ,Ⅲb 2 2 .2 % ,Ⅲc 1 3.4% ) ;转移性淋巴结多为Ⅳ型 ( 66.7% )和Ⅲb型 ( 2 6.7% )。淋巴瘤的血流分型与其分化程度有一定关系 ,转移淋巴结的血流分型与其组织来源无关。结论　淋巴结彩色多普勒血流显像血流形态及分布有助于浅表肿大淋巴结的鉴别诊断 ,并对淋巴瘤的分化程度有一定的提示作用。更多还原

【Abstract】 Objective To depict the characteristics of the flow shape and distribution of superficial lymphadenophathy and to clarify the effiency of color Doppler flow imaging and power Doppler sonography in the differential diagnosis.Methods Prospectively,81 cases with 95 lesions were observed and clarified as four vascular patterns by sonography and were correlated with the histopathological or clinical diagnosis.The four vascular patterns were as follows: type Ⅰ shows central hilar vascularity with radial symmetric branches; type Ⅱ shows eccentric hilar vascularity with deformed radial branches; type Ⅲ shows subcapsular vessels(Ⅲa),mixed vessels(Ⅲb),or multifocal hilar vasculature(Ⅲc); type Ⅳ shows spotted or peripheral flow signals.Results The majority ( 85.0% ) of the benign reactive nodes revealed a vascular pattern of type Ⅰ,while a few ( 10.0% ) showed that of type Ⅱ.The most( 97.8% ) of lymphoma showed the patterns of type Ⅱ( 33.3% ) and type Ⅲ( 64.5% , and Ⅲa 28.9% ,Ⅲb 22.2% ,Ⅲb 13.4% ,respectively).The vascular patterns of metastatic lymphadenopathies were of type Ⅳ( 66.7% ) and type Ⅲb(26.7%).The lymphoma which revealed a vascular pattern of type Ⅱ were mostly of high grade differentiation in pathological results.The differrent vascular types of metastatic nodes has no correlation with its histologic source.Conclusions Color Doppler sonography is a valuable method for aid in the differential diagnosis of superficial lymphadenophathy by using findings of intranodal vascularity.更多还原
