An ovarian cyst is a fluid-filled sac that can occur inside or on the
surface of the ovary. Many women will develop an ovarian cyst at some
point in their life. Most cysts are benign (non-cancerous),
non-dangerous, resolve on their own, and require no treatment. Ovarian
cysts are usually painless and only cause discomfort if they twist,
rupture, or bleed
A postmenopausal woman who develops an ovarian cyst is less likely to
have a benign cyst than a woman of reproductive age. If an ovarian
cancer is removed and subsequently found to be malignant, the patient
may need to undergo additional abdominal surgery for proper treatment
and staging. This includes removal of the contralateral ovary,
hysterectomy, and omentectomy.
Ovarian cyst size
The most important question in evaluating ovarian cysts is whether there
are any suspicious features for malignancy. There are several factors
that can help predict whether a cyst is cancerous or not. The first is
the size of the cyst. Very large cysts, usually larger than 9 or 10 cm,
are less likely to resolve spontaneously than small cysts. If a cyst
contains a large number of solid components or separations, this can
also be a sign of malignancy
Ovarian Cyst Management
Doctors detect most ovarian cysts accidentally during a routine pelvic exam
or an ultrasound of the lower abdomen that is done for other reasons. When a
woman has symptoms, they are often nonspecific in nature, such as:
- Abdominal bloating or pressure
- Menstrual irregularities
- Constipation
- Urinary incontinence
- Urinary frequency
- Pain during intercourse (dyspareunia)
Abdominal or transvaginal ultrasound or abdominal computed tomography (CT)
scan help doctors confirm the diagnosis. When these imaging procedures are
inconclusive, the doctor may perform a diagnostic laparoscopy to examine the
cyst and take a tissue sample for biopsy
Ovarian cyst ultrasound
The main value of ultrasound in the treatment of ovarian cysts is to
distinguish between a physiological cyst and a pathological cyst and the
likelihood that any pathological tumor is malignant. Several studies have
concluded that ultrasound is the best imaging technique for evaluating
ovarian cysts. The following information should be obtained from an
ultrasound examination of an ovarian tumor
• The side of the lesion unilateral/bilateral
• The size: if possible three dimensions
• Consistency: cystic/solid (size and regularity of solid components)
• Internal structures: unilocular, multilocular, complex. Nature of thin /
thick septa
• Inner wall: smooth and irregular presence of papillary projections (solid
projections into the cyst cavity from the cyst wall> 3 mm in height)
• Ecogenicity: compared to the myometrium
It is suggested that some features of ultrasound can be used to predict histological diagnosis. Dermoid cysts are a good example and are easily recognizable on ultrasound due to their fat and hair content. The most
characteristic feature is the presence of a "white ball" in the corner of
the cyst, this corresponds to hair and sebum. The free hair inside the cyst
appears as long echoic lines. There are often significant shadows that make
it difficult to accurately assess the size of the cyst
Ovarian cyst complications
Ruptured ovarian cyst
Ovarian cysts can rupture, twist, bleed, or become infected,
causing severe pain, nausea, and vomiting. A ruptured cyst often
occurs after exercise, intercourse, trauma, or even a pelvic exam.
Torsion (twisting) and bleeding are more likely in right-sided
ovarian cysts
Ruptured cysts, which are rare, can cause severe pain and
internal bleeding. This complication increases the infection risk
and can be life-threatening if left untreated
Ovarian Cyst Treatment
Treatment of an ovarian cyst depends on the type and size of the cyst
and the age of the woman. If the ultrasound exam finds the cyst to be
simple, a "wait and see" plan ("expectant management") may be
appropriate, because many simple ovarian cysts resolve spontaneously.
The woman should repeat the ultrasound 6 to 8 weeks after the simple
diagnosis of a cyst. If the cyst persists, the patient is usually
referred for a surgical evaluation, which is more likely to be done
laparoscopically
• Watchful waiting: Small cysts that are purely fluid-filled and
smaller than 4-5 cm can be observed for 1-3 months and usually resolve
without treatment
• Medications: Women with a tendency to develop functional cysts
are sometimes given medications that contain hormonal contraceptives,
such as birth control pills, which can prevent new cysts from
forming
Can contraceptives help with ovarian cysts?
Hormone management with a combination of estrogen and progesterone,
such as oral contraceptives, transdermal patches, or vaginal rings, can
help suppress ovarian function and help resolve functional cysts. They
can also help reduce the risks of developing ovarian cysts
• Surgery: In older women, a cyst usually requires surgical
evaluation. Surgery may also be needed if a cyst is large, has solid
components, is growing, or is causing pain
If any of these treatment regimens fail to control symptoms. The type
of surgery performed can depend on factors such as the patient's age,
size of the mass, or the desire to have children in the future. Several
types of surgery may be considered, including ovarian cystectomy,
unilateral or bilateral salpingo-oophorectomy, and hysterectomy in women
over the age of 40 who are performed at childbearing age. Surgery can be
performed laparoscopically, laparotomically, abdominally, or vaginally
(usually only done if a hysterectomy is also performed)
When ovarian cysts require further evaluation, they can usually be
evaluated and treated with laparoscopic surgery, in which a narrow
telescope-like instrument is used to view the pelvic organs. Additional
surgical instruments are inserted through small incisions to perform the
surgery. This is usually done under general anesthesia. Very large cysts
or cysts more suspected for cancer may require more extensive
surgery
Ovarian cyst prevention
Ovarian cysts cannot be prevented. However, routine gynecological exams
can detect ovarian cysts early. Ovarian cysts present in:
- Menarche adolescents and adults
- Postmenopausal women
- Who uses the birth control pill
Benign ovarian cysts do not become cancerous. However, ovarian cancer
symptoms can mimic the symptoms of an ovarian cyst. Therefore, tell your
doctor about symptoms that may indicate a problem. It is important to
visit the doctor and get a correct diagnosis
