Ancillary structures to main structure. Among health professionals, adnexa usually refers to the fallopian tubes, broad and round uterine ligaments and the ovaries, considered together. Other adnexae in the body include those of the skin (which are more commonly called skin adnexae and include the sweat and apocrine glands, hair and nails) and the eye (which include the eyelids, lacrimal apparatus and orbital tissue), for which the phrase accessory visual structures is more commonly used.


Appendage, ancillary part.
(1) Ovaries, fallopian tubes, associated uterine ligaments—broad, round.
(2) The ancillary glands and structures of the skin—e.g., hair follicles, sebaceous glands.

(b) A ruptured left teratoma with spread content was noted, which has formed an adhesional complex with the bilateral adnexa. Besides, there was severe adhesion and purulent fluid with the content clotting over the organs in the pelvis.

Caption: FIGURE 2: On contrasted MR a lesion measuring nearly 58 mm x 68 mm cyst with an increased signal intensity (30 HU), which fills Douglas recess and extends into the left adnexa. Initially the lesion was thought to be a left ovarian cyst but histopathology report demonstrated a metastatic lesion of renal clear-cell carcinoma with dimensions of 70 mm x 50 mm x 50 mm.

The intra-operative frozen section consultation of the left adnexa showed endometrial glands and stroma distributed within a vascular connective tissue, features highly suggestive of endometriosis.
On CT images of our patient, uterus was significantly enlarged and replaced by multiple contour deforming fibroids, which were involving the right adnexa, invading the right ovarian vessels, and extending into the right ovarian vein, inferior vena cava (IVC) and right atrium of heart.
(The adnexa of the uterus comprises the space occupied by the ovaries and fallopian tubes in women.) The study involved 22 international oncology centers, referral ultrasonography, and general hospitals and included more than 5,000 patients followed between 1999 and 2012.
Each number corresponds to a compartment in the pelvis, starting from the left adnexa, and going down to the pouch of Douglas and back up to the right adnexa.
Intraoperatively, the IUD was found to be partly buried in right adnexa and was firmly attached to right tube and ovary.
An evaluation of the adnexa was slightly limited secondary to multiple tortuous pelvic veins (FIGURE 1).
