VP63.13: Association of 2D and 3D transvaginal ultrasound findings of adenomyosis in symptomatic women of reproductive age: a prospective study

To evaluate the association of 2D and 3D transvaginal ultrasound (TVUS) findings with adenomyosis symptoms. This cross-sectional study enrolled 78 women, between 18–40 years old with abnormal uterine bleeding (AUB), infertility and/or pelvic pain, from January to December 2018. All included patients underwent 2D TVUS and 3D TVUS performed by an expert sonographer. TVUS signs of adenomyosis were identified according to the consensus of MUSA group. Adenomyosis was classified as focal of the inner myometrium or (JZ), focal of the outer myometrium and diffuse. Mean age was 31.6 ± 5.8 years old. The prevalence of adenomyosis by TVUS was 55.12%. The types of adenomyosis were the focal of the inner myometrium or (JZ) in 51.1%, focal of the outer myometrium in 25.6% and the diffuse in 23.3%. Logistic regression analysis of clinical variables showed significant association of TVUS findings of adenomyosis with older age and with the presence of abnormal uterine bleeding (AUB). The linear striae at 2D TVUS presented significant specificity for AUB (91.3%; p = 0.037) and the myometrial cyst presented significant specificity for dysmenorrhea (100%; p = 0.346). Irregular JZ at 3D TVUS had relevant specificity for AUB (78.2%; p = 0.003) and interrupted JZ had significant specificity for the presence of dyspareunia (72%; p = 0.04). We observed increased prevalence of infertility and abnormal uterine bleeding as more severe was the adenomyosis at TVUS. Findings of adenomyosis by 2D and 3D transvaginal ultrasound showed association with age, dysmenorrhea, abnormal uterine bleeding and dyspareunia. There was greater prevalence of symptoms as more severe was the adenomyosis evaluated by TVUS.
