Treatment-related changes in adenomyosis: a primer for radiologists.

Adenomyosis is a common, estrogen-dependent condition where endometrial tissue grows within the myometrium, often accompanied by smooth muscle hypertrophy. Initially thought to represent a condition primarily seen in multiparas with menorrhagia, and dysmenorrhea, adenomyosis is now increasingly recognized in younger patients and those with infertility and subfertility. As a result, conservative treatments aimed at preserving the uterus and improving reproductive outcomes have gained attention to treat adenomyosis. While research has largely focused on managing abnormal uterine bleeding and dysmenorrhea, there is limited evidence on the treatment of infertility associated with adenomyosis, particularly in terms of imaging follow-up. This paper reviews the emerging literature, highlighting key imaging findings before and after uterus-preserving treatments for adenomyosis, to better inform management and decision-making.
