摘　　要：目的探讨阑尾粘液性囊腺瘤的超声声像图特征,评价超声对阑尾粘液性囊腺瘤的诊断价值。方法回顾性分析14例阑尾粘液性囊腺瘤患者超声图像,总结其声像图特点,与手术及病理检查结果相结合。结果阑尾粘液性囊腺瘤的超声特征为肿瘤位于右下腹,一端与盲肠相通,一端为盲端,大小不一,但横径一般>2cm,呈单房或多房,长条状或椭圆形,壁较厚,较光滑,内有细小絮状光点,透声欠佳,肿瘤周边炎症反应轻微,无网膜包裹,肠系膜无肿大淋巴结。结论超声对诊断阑尾粘液性囊腺瘤有重要价值。Objective To explore the ultrasound characteristics of mucinous cystadenoma of the appendix and evaluate its diagnostic value.Methods Fourteen cases of mucinous cystadenoma of the appendix were diagnosed by ultrasonic examination and confirmed by surgery and pathology.The ultrasound findings and distribution of color Doppler flow signals were observed and analyzed in comparison with the surgical and pathological results.Results Ultrasound revealed a unilocular or multilocular cystic mass located in the right lower quadrant area with clear boarders,smooth and thick wall,and inconsistent internal echogenicity.The maximal outer diameter of the mass was 2 cm or greater in attachment to the cecum,lacking of periileal inflammatory changes such as in the periileal lymph nodes and echogenic periappendiceal epiploon.Conclusion Ultrasound is of high value in the diagnosis of mucinous cystadenoma of the appendix.
