Abstract:
Objective:To investigate the ultrasonographic and clinical features of postmenopausal ovarian endometriosis(OEM).Methods:Clinical, transvaginal sonography(TVS)and pathological data of 26 postmenopausal OEM patients confirmed by surgery and histology in our hospital from June 2014 to June 2019 were included in this retrospective analysis.The ages of patients ranged from 47 to 65 years(median age: 57 years old), and the age at natural menopause was(48.8±3.3)years.The duration after menopause was 1-25 years(median duration: 8 years). Transvaginal sonography(TVS)results were compared with pathological data.Results:A total of 36 adnexal lesions were found by TVS.Postoperative pathological examination confirmed 39 lesions, of which 76.9%(30 cases)were OEM lesions and 23.1%(9 cases)were non-OEM lesions in the ovary.92.3% of the adnexal lesions(36 cases)were effectively screened by TVS, and 3 lesions less than 1 cm were missed in the ovary.Among 26 subjects, unilateral OEM lesions accounted for 84.6%(22 cases). Simple cysts were the most common concurrent condition(6 cases), followed by uterine leiomyoma(4 cases), ovarian cancer(2 cases)and serous cystadenoma(1 case). The sizes of 30 postmenopausal OEM lesions ranged from 0.8 cm to 6.6 cm, and 53.3%(16 cases)were anechoic, typical of OEM on TVS.TVS found that 40.0%(12 cases)showed no specific sonographic features, 16.7%(5 cases)showed a heterogeneous echo pattern, 13.3%(4 cases)showed a homogeneous hypoecho pattern, and 10.0%(3 cases)showed a hypoechoic mass with strong internal echo, following a shadow behind it.The rate of missed diagnoses of 30 postmenopausal OEM lesions by TVS was 30.0%(9 cases), of which 23.3%(7 cases)were misdiagnosed as solid masses in the adnexal area on TVS, and 6.7%(2 cases)were missed on TVS(OEM lesions less than 1.0 cm).Conclusions:Ultrasonographic heterogeneity exists in postmenopausal OEM patients.Unilateral and anechoic ultrasound is the most common type of ultrasound imaging.It is of great significance to pay attention to TVS examination and corresponding ultrasound imaging analysis in postmenopausal women for the early diagnosis of postmenopausal OEM.
