Adnexa clinically refers to the fallopian tubes and ovaries combined, thus, adnexal cysts are not necessarily ovarian cysts. During gynecological ultrasound, these are often reported as cysts in the adnexal area because the proximity of the ovaries and fallopian tubes makes it difficult to conclusively determine if an adnexal cyst is an ovarian cyst. Clinically, cysts in the fallopian tubes are also referred to as cysts in the adnexal area. Distinguishing them often requires surgery to see the exact location of the cyst for identification.
