adnexa
Pronunciation: ad-NEK-suh
The anatomical structures adjacent to the uterus, including the ovaries, fallopian tubes, and supporting ligaments.
Full Definition
The adnexa (plural of adnexum) refers to the accessory structures of the uterus, primarily consisting of the ovaries, fallopian tubes, and their supporting ligaments and blood vessels. During pelvic examination, the adnexa are palpated bimanually to assess for masses, tenderness, or abnormal mobility. Common adnexal pathology includes ovarian cysts, tubo-ovarian abscesses, ectopic pregnancy, and ovarian torsion. The term 'adnexal mass' is frequently used in clinical documentation to describe any palpable or imaging-detected abnormality in this region. Surgical procedures involving the adnexa include salpingectomy, oophorectomy, or salpingo-oophorectomy.
Usage
Usage note: Singular form is 'adnexum' but rarely used; commonly misspelled as 'annexa'.
