阴式三维超声在阴道壁表皮囊肿中的应用

Application of transvaginal three-dimensional ultrasonography in epidermal cysts of vaginal wall

目的探讨经阴式三维超声对阴道壁表皮囊肿的诊断价值。方法回顾性分析经阴式三维超声诊断、病理证实的阴道壁表皮囊肿患者的声像图特点。结果 20例阴道壁表皮囊肿患者共有囊肿24个。声像图表现为边界清,椭圆形高回声。囊肿多位于阴道后壁下段,常单发,一般<1 cm。全部患者均无临床症状,多发生于生育年龄妇女。二维超声显示囊肿位于阴道前壁1个、后壁21个、左侧壁2个;三维超声显示囊肿位于左前壁1个、左后壁13个、右后壁8个、左侧壁2个。结论经阴式三维超声与二维超声图像相结合可为临床提供更准确的囊肿定位信息。

Objective To investigate the value of transvaginal three-dimensional ultrasonography in the diagnosis of vaginal cysts of vaginal wall. Methods The features of ultrasonic imaging of 20 cases with vaginal cysts of vaginal wall confirmed by transvaginal three-dimensional ultrasonography and pathology were retrospectively analyze. Results There were 24 cysts among the 20 cases. The ultrasonic features of the cysts were well-defined borders with oval hyperechogenicity. Most cysts were single and located in the lower posterior vaginal wall with diameter 〈1 cm. All the cases had no clinical symptoms and most of them got cysts in childbearing age. According to two-dimensional ultrasonography, 1 lesion was located in the anterior vaginal wall, 21 in the posterior vaginal wall, and 2 in the left-lateral vaginal wall. According to transvaginal three-dimensional ultrasonography, 1 lesion was located in the left-anterior vaginal wall, 13 in the left-posterior vaginal wall, 8 in the right-posterior vaginal wall, and 2 in the left-lateral vaginal wall. Conclusion The combination of transvaginal three-dimensional ultrasonography and two-dimensional ultrasonography can provide clinical diagnosis with more accurate information about the location of cysts.
