The ultrasound manifestation of adenomyosis is a diffusely enlarged uterus, and if an ultrasound is performed during menstruation, multiple dark areas of fluid in the myometrium will be found, which, when combined with the clinical history, is adenomyosis. In clinical practice, patients with adenomyosis often present with particularly heavy menstruation and progressively worse menstrual pain. It is recommended that some treatment can be given, for example, a Mannedol ring can be applied to shrink the endometrium, and the treatment will be achieved. If the treatment with the IUD is not effective and the patient does not have fertility requirements, surgery may be an option. In addition, adenomyosis may clinically cause infertility in about 50% of patients.
