VP07.02: Ultrasonographic diagnosis of adenomyosis associated at Müllerian anomalies

Two main theories have been proposed to explain the origin of adenomyosis. The first theory postulated that adenomyosis results from invagination of the endometrial basalis into the myometrium as a repair mechanism after injury. Alternatively, it has been posited that during Mullerian duct development and fusion, some remnants of the embryonic tissue may be misplaced in the myometrium, subsequently giving rise in adult women to adenomyosis. The objective of our study is to evaluate the presence of adenomyosis in patients who had Müllerian anomalies (CUAs). From 01/01/2018 to 31/12/2019 265 patients with CUAs were included. We evaluated the presence of adenomyosis in these patients. CUAs were classified according to the ESHRE-ESGE consensus of uterine anomalies. We recorded the presence of adenomyosis in each class of anomaly. Of 265 was 39 (14.71%) also presented adenomyosis. Relationship of adenomyosis and uterine anomaly and relative frequency (%) are shown in table 1. No findings of adenomyosis in the hypoplasia group (U5) were observed. The most prevalent Müllerian anomaly associated with adenomyosis corresponds to U4 or hemi-uterus. We believe that in patients with Müllerian anomalies a thorough search for adenomyosis must be performed, especially in the cases of hemi-uterus.
