卵巢纤维瘤的超声诊断探讨

Ultrasonic diagnosis of ovarian fibroma

目的：探讨术前超声诊断卵巢纤维瘤的价值。材料与方法：回顾性分析我院１９９０～２０００年１０年间经手术病理证实的２８例卵巢纤维瘤的声像图特征。结果：①提出卵巢纤维瘤可分为衰减型和混合回声型两型。②术前超声对卵巢纤维瘤的诊断率为８５．７１％，较临床诊断率明显为高（５７．１４％）。③超声对衰减型纤维瘤诊断率较高，可达９５．４５％。而对混合回声型纤维瘤诊断率较低，仅５０％。④纤维瘤的彩色血流显示率为３３．３３％，其中衰减型较低为２５％，混合回声型较高为６６．６７％。⑤腹部加阴道超声检查（８７．５０％）对卵巢纤维瘤的诊断率较单纯腹部超声检查（８５．００％）更高。结论：术前超声，尤其是腹部与阴道超声联合检查，对卵巢纤维瘤具有较高的诊断率，对临床制定手术方案具有重要参考价值。

Objective: To discuss the value of preoperative ultrasonography in diagnosing ovarian fibroma. Materials and Methods: Analyzing ultrasonographic features of 28 cases of ovarian fibroma proved by operation and pathology. Result: ① Ovarian fibroma could be divided into two echo types: 'decayed' and 'mixed'. ②Ultrasonic confirmed diagnosing ratio(85. 71% ) was higher than that of clinic(57. 14% ). ③Ultrasonic confirmed diagnosing ratio of decayed echo fibroma(95. 45% ) was higher than that of mixed type (50%). ④Color now in fibroma was 33. 33% positive, and lower in decayed type(25%) than in mixed type(66. 67% )⑤ The con- firmed diagnosing ratio was higher in those undertaking transabdominal and transvaginal ultrasonography(87.50%) than in those only undertaking transvaginal ultrasonography(85. 00%). Conclusion: Ultrasonography of ovarian fibroma, especially transabdominal ultra- sonography plus transvaginal ultrasonography, is valuable in preoperative diagnosing.
