Diagnosis
How is adenomyosis described on ultrasound reports?
The short answer
Ultrasound reports usually describe features suggestive of adenomyosis rather than a single yes/no finding. Reports may note an enlarged uterus, patchy or uneven uterine muscle, cysts within the muscle, or a localized mass-like area called an adenomyoma.
On ultrasound, adenomyosis is usually described as features suggestive of adenomyosis rather than a single yes-or-no finding, because the condition involves endometrial-like tissue growing into the uterine muscle, or myometrium. Reports may note an enlarged or tender-appearing uterus and a heterogeneous (patchy or uneven) texture of the myometrium, reflecting diffuse changes within the uterine wall.
More specific ultrasound descriptions can include myometrial cysts, subendometrial lines or buds, and irregularity where the inner uterine lining meets the muscle. If the disease is localized, it may be described as focal adenomyosis or an adenomyoma: a mass-like area that can resemble a fibroid on imaging.
If your report feels vague or uses terms like “possible” or “borderline,” that often reflects real limits of ultrasound and differences in imaging technique and reader experience, not the severity of your symptoms. Our team can help interpret the exact wording of your ultrasound in context (including whether the pattern sounds focal, diffuse, or mixed) and decide whether additional imaging like MRI would meaningfully clarify the diagnosis and next steps.

Understanding Your Ultrasound Results
Ultrasound can hint at adenomyosis through specific signs, not just a clear yes or no. Our specialists can explain these findings and guide you toward the right care plan.
Questions people ask next
All diagnosis questionsDiffuse vs focal adenomyosis: what’s the difference?
Diffuse adenomyosis is spread throughout much of the uterine muscle, while focal adenomyosis is confined to one area and may form a mass called an adenomyoma. A focal lesion may be better suited to uterus-sparing surgery, while diffuse disease can be harder to remove without weakening the uterus.
How is diffuse adenomyosis confirmed on MRI or ultrasound?
Diffuse adenomyosis is usually suggested, not proven, by MRI or ultrasound findings that match your symptoms. MRI may show a thickened junctional zone and tiny cysts in the uterine muscle; ultrasound may show streaky muscle, asymmetric thickening and fan-shaped shadowing.
How is adenomyosis diagnosed—MRI, ultrasound, or surgery?
Adenomyosis is most often diagnosed using your symptoms, a pelvic exam, and imaging, usually an expert transvaginal ultrasound and sometimes an MRI. Most patients do not need surgery to confirm it; imaging and your clinical story typically provide enough clarity.
Can adenomyosis be missed on ultrasound or MRI?
Yes, adenomyosis can be missed on ultrasound or MRI, especially when it is mild, patchy, or early in its course. A normal or borderline scan does not rule it out if your symptoms and exam still fit, and subtle ultrasound findings may be interpreted differently.
