Abnormal Uterine Bleeding: Why, When, and Who Should Consider Imaging?

Why • When • Who Series

Abnormal uterine bleeding (AUB) is a common concern among women of all ages, presenting as irregular or heavy menstrual bleeding, sometimes with lower abdominal pain. The causes vary widely depending on the patient’s age and range from benign structural issues to hormonal dysfunction, fertility-impacting conditions, and malignancies that require urgent attention.

I’m Dr. Vahid Alizadeh. In this article from the “When, Why, Who” series, I will explain how imaging plays a crucial role in diagnosing the causes of AUB and informing treatment plans, ensuring that women receive accurate and timely care.

Abnormal Uterine Bleeding (AUB) MRI Imaging

 A Patient’s Journey:

From Chronic Symptoms to Clear Answers

A 38-year-old woman has experienced heavy, irregular periods for over a year, with intermittent pelvic pain. She has seen multiple physicians and undergone laboratory tests, but her symptoms persist. An ultrasound revealed a possible endometrial polyp, while an MRI identified multiple intramural fibroids and confirmed the polyp within the uterine cavity. This clarity allowed her gynecologist to plan appropriate treatment, improving her symptoms and fertility prospects.

 Why Is Imaging Important in Abnormal Uterine Bleeding?

AUB can stem from:

  • Structural abnormalities (polyps, fibroids, adenomyosis)
  • Hormonal dysfunction (including pituitary-related causes)
  • Malignancies (especially in post-menopausal women)
  • Ovarian and adnexal masses producing hormones or causing mechanical issues

Questions about your scan or report?

 How Imaging Helps:

  • Ultrasound is the first-line tool for assessing the endometrium, uterine size, and adnexa.
  • MRI provides a detailed evaluation of uterine and adnexal structures, accurately characterizing fibroids, adenomyosis, and polyps and distinguishing between benign and suspicious masses.
  • MRI of the brain may be indicated when central hormonal causes (pituitary issues) are suspected.
  • Imaging is essential for staging and treatment planning if malignancy is suspected.

When Should Imaging Be Performed for AUB?

Urgent Imaging Is Needed If:

  • Severe bleeding with hemodynamic instability
  • Post-menopausal bleeding
  • Acute pelvic pain with bleeding, raising suspicion for complications like torsion or malignancy

Routine Imaging Is Beneficial When:

  • Chronic heavy or irregular bleeding impacts the quality of life or fertility
  • There is a history of failed medical management
  • Evaluation before assisted reproductive procedures

 

Who Should Get Imaging and Expert Review?

Candidates for Imaging Include:

  • Women with chronic abnormal bleeding unresponsive to treatment
  • Those with suspected structural abnormalities (polyps, fibroids)
  • Patients with fertility concerns
  • Women at increased cancer risk due to age or family history
  • Those with suspected hormonal dysfunction requiring pituitary evaluation

 Why Second Opinions Matter:

Determining the exact cause of AUB can be challenging, particularly in differentiating between benign and malignant conditions, as well as between structural and hormonal causes. A second opinion from an expert radiologist ensures the accurate interpretation of existing imaging and provides recommendations for further evaluation, helping to prevent delays that can impact treatment and outcomes. This is particularly important in chronic cases, where scattered imaging from different facilities requires an integrated review to create a clear diagnostic roadmap.

FAQs

Why is imaging necessary for diagnosing abnormal uterine bleeding?

Imaging is essential because AUB can be caused by structural problems like polyps, fibroids, or adenomyosis, as well as hormonal dysfunction or malignancy. Ultrasound provides an initial assessment of the uterus and adnexa, while MRI offers detailed visualization that helps identify the exact cause. Accurate imaging ensures the right treatment plan and avoids delays in managing serious conditions.

When should I get imaging for abnormal uterine bleeding?

Urgent imaging is recommended for severe bleeding, post-menopausal bleeding, or bleeding with acute pelvic pain. Routine imaging is helpful for women with long-term symptoms, failed treatments, suspected polyps or fibroids, and those planning fertility procedures. Timely imaging helps detect the cause early and guides appropriate care.

Which imaging test is best for identifying fibroids, polyps, or adenomyosis?

Ultrasound is the first test used to evaluate endometrial thickness and overall pelvic anatomy. MRI is the most accurate method for characterizing fibroids, adenomyosis, and endometrial polyps. It differentiates benign findings from suspicious masses and provides clear information for treatment planning.

Who needs a second opinion for abnormal uterine bleeding imaging?

A second opinion is important for women with persistent AUB despite treatment, unclear or conflicting imaging results, fertility concerns, or potential cancer risk. It is also helpful when imaging from different facilities needs to be reviewed as a whole. An expert radiology review ensures no important detail is missed and offers a clear diagnostic direction.

Can abnormal uterine bleeding affect fertility and how does imaging help?

AUB can reduce fertility when caused by polyps, fibroids, hormonal problems, or endometrial abnormalities. Imaging helps identify issues that interfere with implantation or ovulation. Detecting these problems early allows for targeted treatment and improves the chances of a successful pregnancy.
