A lump in the tissue of the adnexa is known as an adnexal mass. The structures (organs or tissues) which are either in the proximity of the uterus or are closely related to the functioning of the uterus are referred to as adnexa. These structures include the ovaries, fallopian tubes, connective tissues, ligaments and associated blood vessels.
There are various types of adnexal masses but they can be broadly classified into gynecological and non-gynecological. Masses of non-gynecological origin include appendix masses, bowel related conditions and pelvic kidney amongst others. However, in this article we will focus on adnexal masses from gynecological sources.
Gynecological adnexal masses : Gynecological adnexal masses can be further divided into ovarian, tubal, tubo-ovarian and paraovarian masses.
