韧带样型纤维瘤病的超声诊断探讨

Study of Ultrasound in the Diagnosis of Desmoid - type Fibromatoses

目的:本文通过分析韧带样型纤维瘤病的超声声像图表现,从而提高超声对该病的认识和诊断水平。方法:回顾性分析经手术病理证实的13例韧带样型纤维瘤病的超声特征,其中腹外型6例,腹壁型6例,腹内型1例。结果:13例肿瘤的内部回声欠均匀,无囊性变,内部血供均较丰富。其中,腹壁及腹外型病变质硬、固定,腹内型肠系膜病变质硬、活动度大。浸润性生长者形态不规则、边界欠清、无明显包膜。膨胀性生长者形态规则、边界较清楚、可见部分包膜。结论:韧带样型纤维瘤病有一定的超声声像图特征,结合病史、体征,可对该病的诊断或鉴别诊断提供重要依据。

Objective： Through analyzing the ultrasonography characteristics of desmoid-type fibromatoses , to promote the di- agnostic accuracy and understanding of this kind of disease. Methods： Ultrasound image features of 13 cases of desmoid-type fibroma- toses confirmed surgically and pathologically were analyzed retrospectively. Six cases were the extra-abdominal type ,6 cases were in ab- dominal wall muscles and 1 was the intra-abdominal type. Results：The common features of 13 cases were uneven internal echo, no cystic changes and abundant color doppler blood flow. Among these cases, the features of extra-abdominal type and abdominal wall type were hard and fixed, as for the intra-abdominal type, the mass in the mesentery was hard and with large range of movement. The ag- gressive-growing cases had irregular figure, ill-defined border and had no obvious coat. The expansive growing cases had regular figure, well-defined border and part of the capsule was visible. Conclusion： Desmoid-type fibromatoses has certain sonographic characteris- tics. Combined with clinical history and physical sign, the sonographie characteristics provide important basis for diagnosis or differenti- al diagnosis of this tumor.
