BACKGROUND & OBJECTIVES: This study was carried out to determine the appearance of various cystic ovarian lesions on transvaginal real-time ultrasonographic elastography and to investigate its potential in the differential diagnosis of cystic ovarian lesions.
Twenty six women (age range, 27-71 yr; mean age 42 ± 16 yr) with cystic ovarian masses underwent transvaginal B-mode and Doppler ultrasonography, and transvaginal real-time ultrasonographic elastography. Those having ovarian cysts with solid components underwent to biopsy or surgical excision. The elasticity colour code (pattern 1-5), and strain index of cystic ovarian lesions were analyzed and associated with histopathological diagnosis.
Eleven of 26 ovarian cysts (42%) (diameter range, 3.2-4.5 cm) without solid component were not colour coded with blue or colour coded with blue-red-green heterogenous mosaic pattern. Fifteen of 26 cystic ovarian lesions (58%) (diameter range, 3.5-6.5 cm) had solid components. Among these, two had colour pattern 5, their strain indexes were 3.7 and 4, and their histopathologic diagnosis were germ cell carcinoma. One had colour pattern 5, with strain index 13.6, and histopathologic diagnosis was clear cell carcinoma.
INTERPRETATION & CONCLUSIONS: Transvaginal real-time ultrasonographic elastography has potential role in the differential diagnosis of cystic ovarian lesions and this technique may be useful in differentiation of the benign lesions from those of malignant.
本研究旨在探讨经阴道实时超声弹性成像在各种卵巢囊性病变中的表现，并探讨其在卵巢囊性病变鉴别诊断中的应用价值。
对 26 例（年龄 2771 岁，平均年龄 42±16 岁）卵巢囊性肿块患者进行经阴道二维超声、彩色多普勒超声及实时超声弹性成像检查，对有实性成分的卵巢囊肿进行活检或手术切除。分析卵巢囊性病变的弹性彩色编码（15 型）和应变指数，并与组织病理学诊断相关联。
26 个卵巢囊肿（直径 3.24.5 cm）中，11 个（42%）无实性成分，未出现蓝色或蓝-红-绿混合马赛克样彩色编码；26 个有实性成分的卵巢囊性病变（直径 3.56.5 cm）中，15 个出现彩色编码（58%），其中 2 个为 5 型，应变指数分别为 3.7 和 4，组织病理学诊断为生殖细胞癌；1 个为 5 型，应变指数为 13.6，组织病理学诊断为透明细胞癌。
经阴道实时超声弹性成像在卵巢囊性病变的鉴别诊断中有一定的应用价值，该技术可能有助于区分良性和恶性病变。
