Endometriosis happens when tissue similar to the uterine lining grows outside the uterus and can cause pain, bleeding problems, or fertility issues.
Common symptoms include painful periods, pelvic pain, pain during sex, bowel or bladder discomfort during periods, heavy bleeding, and sometimes difficulty getting pregnant.
Imaging helps when doctors are looking for ovarian endometriomas, deep pelvic disease, or other pelvic causes of pain, although some endometriosis can still be difficult to see on scans.
Ultrasound and MRI may help show ovarian endometriomas or deep pelvic disease, though some endometriosis can still be hard to see on imaging.
Care may include pain treatment, hormone-based therapy, fertility support, or surgery depending on symptoms and goals.
This entry explains the condition. The next step is having a radiologist interpret your specific scan, not a general definition.
