How are ovarian endometriomas diagnosed?
Physical examinations and imaging tests can reveal if you have an ovarian endometrioma. If the cyst is particularly large, your doctor may notice it during a pelvic examination. Transvaginal ultrasounds, magnetic resonance imaging (MRIs), and computed tomography scans (CT scans) can all detect a mass.
However, neither an exam nor imaging provides enough information for your practitioner to determine whether the lump is an ovarian endometrioma.
Because they both contain blood, an ovarian endometrioma and a hemorrhagic cyst, for example, can seem identical on imaging examinations. Your provider must test the tissue to ensure it is an ovarian endometrioma.
