Adenomyosis is a condition where endometrial tissue that lines the uterus grows into the muscles of the uterus. The growth makes the uterine walls thicker and may lead to substantial and painful menstrual bleeding, as well as extended menstrual periods.
An ultrasound may be done to check for growths or tumours in the uterus. An MRI may also be done if a diagnosis is not possible with an ultrasound.
A pelvic examination may be done to check the uterus for swelling.
