What is adnexal mass?
An adnexal mass is a lump of tissue in or near the female reproductive system, usually in an ovary or uterine tube. They are called "adnexal" because of their association with the adnexa of the uterus, which are appendages related to the uterus. These appendages include the tissue around the uterus, ovaries, and uterine tubes. Adnexal masses can also be called pelvic masses.
