高频彩色多普勒超声对猫抓病性淋巴结炎的诊断价值

摘要

Objective To Investigate the value of diagnosing cat-scratch lymphadenitis (CSD) using high frequency color Doppler ultrasound.Methods 8 cases with lymphadenitis confirmed by needle biopsy and surgery causing by CSD from February 2014 to August 2014 were analyzed.The number,size,shape,distribution,change of the echo and blood flow of lymph node were observed.Results The increscent lymph nodes in the newly diagnosed 8 cases with CSD by high frequency color Doppler ultrasound were mainly distributed in the neck,armpits,upper limbs and groins.There were 4 cases with the increscent lymph nodes in only one part of bodies,and 4 cases in multiple parts of bodies.Some increscent lymph nodes were surrounding by small lymph nodes.The increscent lymph nodes were mostly low echo or very low echo.The corticomedullary differentiation was not clear.The increscent lymph nodes were spherical,oval or lobulated in shape,and blood flow.Conclusion It is a quick and easy method of diagnosing the CSD using high frequency color Doppler ultrasound with the medical history of pet scratched or contacted.Follow-up confirms that high frequency color Doppler ultrasound diagnosis coincided with the laboratory examination diagnosis and clinical diagnosis.It can give the main reference for clinical work.%目的 探讨高频彩色多普勒超声(简称高频彩超)对猫抓病性淋巴结炎的诊断价值.方法 纳入2014年2月至2016年8月经实验室检查及临床穿刺活检与手术确诊的8例猫抓病性淋巴结炎患者,观察其淋巴结的数目、大小、形态、分布、回声变化以及血流情况.结果 超声初诊为猫抓病8例患者的肿大淋巴结主要分布于颈部、腋窝、上肢及腹股沟.单个部位的淋巴结肿大者4例,多个部位淋巴结均有肿大者4例.部分肿大淋巴结周围伴有小淋巴结卫星样分布.肿大的淋巴结多呈均匀低回声或极低回声,皮髓质分界不清,球形、椭圆形或分叶状.其内血流多为低阻型.结论 明确有宠物抓伤及接触病史的前提下,高频彩色多普勒超声对猫抓病性淋巴结炎的诊断快捷、方便,随访证实与实验室检查及临床诊断一致,可为临床治疗提供重要的参考依据.
