彩色多普勒产前诊断胎儿脐带囊肿的影像学分析(附一例报告与文献复习)

The Imaging Analysis of Umbilical Cord Cyst by Color Doppler Flow Imaging

目的：探讨胎儿脐带囊肿的声像图特点，提高对该病的认识。方法通过对曲阜市人民医院收治的一例胎儿脐带囊肿并结合1991～2014年中文文献对该病进行回顾性分析。结果共收集119例脐带囊肿，其中89例为单发，20例为多发，45例位于胎儿侧，25例位于胎盘侧；均表现为低回声、边界清晰的囊性肿块。结论超声是观察和诊断脐带囊肿最有价值的影像学方法。

Objective To discuss the ultrasonographic characteristic of umbilical cord cyst and to deepen the recongnization of the disease. Methods One case was selected from the iles of the QUFU People’s Hospital, and others had been diagnosised and reported from 1991 to 2014 in Chinese literature were reviewed. The clinical and ultrasonic features in 119 patients with umbilical cord cyst were reviewed. Results In China 119 cases were reported, 45 cases were located near the fetus and 25 cases near the placenta. All cases revealed single, well-deined and cystic masses with hyperechogencity. Conclusion Ultrasound is the most valuable imaging methods for diagnosing umbilical cord cyst.
