Adenomyosis

Endometriosis interna; Adenomyoma

Last reviewed: July 23, 2012.

Adenomyosis is uterine thickening that occurs when endometrial tissue, which normally lines the uterus, moves into the outer muscular walls of the uterus.

Causes

The cause is unknown. Sometimes adenomyosis may cause a mass or growth within the uterus, which is called an adenomyoma.

The disease usually occurs in women older than 30 who have had children.

Symptoms

Note: In many cases, the woman may not have any symptoms.

Exams and Tests

During a pelvic exam, the doctor may find an soft and slightly enlarged uterus. The exam may also reveal a uterine mass or uterine tenderness.

An ultrasound of the uterus may help tell the difference between adenomyosis and other uterine tumors. MRI can be helpful when ultrasound does not give definite results.

Treatment

Most women have some adenomyosis as they near menopause but few women have symptoms, and most women don’t require any treatment.

In some cases, pain medicine may be needed. Birth control pills and a progesterone-containing intrauterine device (IUD) can help decrease heavy bleeding.

A hysterectomy may be necessary in women with severe symptoms.

Outlook (Prognosis)

Symptoms usually go away after menopause. A hysterectomy completely relieves symptoms.

When to Contact a Medical Professional

Call for an appointment with your health care provider if you develop symptoms of adenomyosis.

What works?

  • Diagnosis: EndometriosisDiagnosis: Endometriosis
    Period (menstrual) pain is very widespread: About half of all women have it. Some women have such severe pain that every month, for one to three days they are unable to pursue their daily activities. Often, normal doses of painkillers do not help anymore. If this is the case with you, you could have endometriosis.
