In clinical terms, the adnexa include the fallopian tubes and ovaries, so an adnexal cyst is not solely an ovarian cyst; rather, ovarian cysts are just one type of adnexal cyst. Adnexal cysts can also include fallopian tube cysts, but in clinical practice, most adnexal cysts are manifestations of ovarian cysts. Therefore, when patients hear the term "adnexal cyst," they should further inquire whether it is an ovarian cyst, instead of simply assuming it to be one.

Symptoms of ovarian cyst carcinogenesis

The main symptom of malignant transformation of ovarian cysts is increased abdominal pain, which generally occurs on one side, including either the left or right side, since the ovaries are present on both sides. If the cyst is unilateral, rapid growth can cause lower abdominal distension and pain. Therefore, when such symptoms aggravate, timely examination is necessary. Initially, a gynecological examination is recommended to assess the boundaries of the ovarian cyst and to palpate its nature and texture. These are essential evaluations. If there is a potential for malignancy, sometimes nodular changes, which may be metastases, can be detected in the posterior cul-de-sac. Subsequently, an ultrasound should be performed, with vaginal ultrasound generally providing greater accuracy.

Do ovarian cysts hurt?

This ovarian cyst is generally a benign tumor change. Normally, ovarian cysts do not show any symptoms. However, as the cyst grows larger, it may cause an increase in abdominal size and bloating. It may also press on the gastrointestinal tract and the bladder, leading to corresponding urinary and gastrointestinal symptoms. Additionally, changes in body position may lead to acute abdomen, such as ovarian cysts, torsion of the stalk, rupture of ovarian cysts, and other conditions.

Do ovarian cysts require the removal of the ovary?

Generally, ovarian cysts do not require the removal of the ovary; the common practice is to perform a cystectomy, which involves peeling off the cyst from the ovary. After that, the situation of bleeding is assessed. If there is no significant bleeding on the surgical surface, suturing can be done, which preserves both the morphology and function of the ovary. Ovaries are crucial for females as they produce estrogen, progesterone, and also have the function of ovulation. Therefore, removing ovaries would reduce the levels of estrogen and progesterone in the body and decrease ovulation functions, which is why ovary removal is generally not recommended. Typically, the impact of the cystectomy on these ovarian functions is minimal. Thus, recovery tends to be good, with minimal impact on daily life in terms of prognosis.

Is an adnexal cyst the same as an ovarian cyst?

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.

Causes of ovarian cysts

The cause of ovarian cysts is unclear, with many factors that can lead to ovarian cysts. The most common type of physiological ovarian cyst is the follicular cyst. The most common pathological causes are chronic inflammation or abnormalities in hormone secretion and endocrine factors, but most causes are unclear. If an ovarian cyst is discovered, it is recommended to regularly check with a color Doppler ultrasound, which is a common gynecological test for tumor markers. If the results are abnormal, timely surgical treatment is recommended to more directly understand the nature of the ovarian cyst. If the cyst is smaller than five centimeters in diameter and has good internal sound transmission, it can be observed regularly; otherwise, aggressive surgical treatment is advised.
