How is adenomyosis diagnosed?

Healthcare providers often diagnose adenomyosis based on symptoms and one or more of these tests:

  • Pelvic exam: During a pelvic exam, your provider may notice that your uterus has gotten larger, softer, or more painful when palpated.
  • Ultrasound: A transvaginal ultrasound uses sound waves to produce images of pelvic organs. These images can sometimes show thickening of the muscle raising suspicion for adenomyosis.
  • Imaging scans: Magnetic resonance imaging (MRI) scans can show uterine enlargement and thickening of certain areas of the uterus which can be indicative of adenomyosis.
  • Biopsy: Because tissue grows within the uterus walls, the only way to biopsy tissue is after a hysterectomy, which removes the uterus.
