What does adenomyosis mean?

Adenomyosis means that tissue similar to the uterine lining grows into the muscle wall of the uterus (the myometrium). Because this tissue still responds to hormonal cycles, it can swell and bleed with your period—but it’s trapped in the uterine muscle, which can trigger inflammation and pain.

For many people, adenomyosis shows up as heavy or prolonged bleeding, severe cramps, pelvic pressure, or fertility challenges, and the uterus may become enlarged and tender. Unlike endometriosis, adenomyosis stays within the uterus (though it can be diffuse throughout the muscle or more localized as an adenomyoma). If your symptoms fit this pattern, our team can help you make sense of imaging findings and discuss options that match your goals—whether that’s symptom control, fertility planning, or definitive treatment.
