What are ovarian cysts?
Fluid filled sacs
Can be functional based on fluctuating hormones in premenopausal, concerning for malignancy if in postmenopausal
What is the presentation of ovarian cysts?
Usually asymptomatic, found incidentally on USS Pelvic pain Bloating Fullness in the abdomen Palpable pelvic mass if very large cysts
When might ovarian cysts present with acute pain?
Ovarian torsion, haemorrhage, rupture of cyst
What are functional ovarian cysts?
Follicular cysts due to the developing follicle
Most common type of cyst that are harmless and disappear after a few cycles
What are corpus luteum cysts?
Occurs when the corpus luteum fails to break down and instead fills with fluid, may cause pelvic discomfort, pain or delayed menstruation. Common in early pregnancy.
What is a serous cystadenoma?
Tumours of the epithelial cells in the ovary
What are mucinous cystadenomas?
Tumours of the epithelial cells, can become very large and take up lots of space in the abdomen.
What are endometriomas?
Lumps of endometrial tissue within the ovary, occurs in patients with endometriosis, can cause pain, disrupt ovulation.
What are dermoid cysts?
Teratomas, benign ovarian tumours
Come from germ cells, so may contain different tissue types like skin, teeth hair and bone.
Associated with ovarian torsion.
What are sex cord stromal tumours?
Rare, either benign or malignant
Come from stroma or sex cords
What is important in the assessment of an ovarian cyst?
Examine for bloating, reduced appetite, early satiety
Weight loss
Urinary symptoms, pain, ascites, lymphadenopathy
Assess for risk factors of ovarian malignancy
Age, postmenopause, increased number of ovulations
Obesity, HRT, smoking, breastfeeding (protective) FH
What factors will reduce the number of ovulations?
Later onset of menarche
Early menopause
Any pregnancies
Use of the combined oral contraceptive pill
What investigations are needed for ovarian cysts?
If premenoapusal with simple ovarian cyst less than 5cm on USS, do not need further investigations.
CA125 tumour marker for ovarian cancer.
Other tumour markers if complex ovarian mass -
lactate dehydrogenase, alpha fetoprotein, human chorionic gonadotropin
What are causes of a raised CA125?
Not very specific, tumour marker for epithelial cell ovarian cancer
endometriosis fibroids adenomyosis pelvic infection liver disease pregnancy
What is the risk of malignancy index?
Estimates risk of an ovarian mass being malignant
Menopausal status
Ultrasound findings
CA125 level
What is the management of ovarian cysts?
Possible ovarian cancer; complex cysts or raised CA125 requires 2WW referral.
Dermoid cyst - further investigation, consider surgery.
Simple cysts in premenopausal women
Less than 5cm should resolve within 3 cycles, follow up if not
5cm to 7cm routine referral and yearly ultrasounds
More than 7cm consider MRI or surgical evaluation
Simple cysts in postmenopausal women and normal CA125 monitored with USS every 4-6 months.
Persisting or enlarging cysts need surgery; laparoscopy, ovarian cystectomy, possible oophrectomy.
What are the complications of ovarian cysts?
Present with acute onset of pain
Torsion
Haemorrhage into the cyst
Rupture with bleeding into the peritoneum
What is Meig’s syndrome?
A triad of
ovarian fibroma - a benign ovarian tumour
pleural effusion
ascites
Typically occurs in older women
removal of the tumour results in complete resolution of effusion and ascites
What is ovarian torsion?
Where the ovary twits in relation to surrounding connective tissue, fallopian tube and blood supply (the adnexa)
What are the causes of ovarian torsion?
Usually due to ovarian mass larger than 5cm such as a cyst or tumour, more likely with benign tumours.
Can happen in normal ovaries in younger girls before menarche when they have longer infundibulopelvic ligaments.
Twisting leads to ischaemia, if persists can lead to necrosis and function of ovary lost, is an emergency.
What is the presentation of ovarian torsion?
Sudden onset severe unilateral pelvic pain
Pain is constant, gets progressively worse,
Nausea and vomiting
Pain not always severe, can be milder and last longer and can twist intermittently causing pain that comes and goes.
Localised tenderness on palpation, palpable mass in pelvis, but absence does not exclude diagnosis.
How can ovarian torsion be diagnosed?
Pelvic ultrasound, TV ideal, can do TA
Whirlpool sign - free fluid in the pelvic, oedema if the ovary
Doppler may shock lack of blood flow
Definitive diagnosis made with laparoscopic surgery
What is the management of ovarian torsion?
Emergency admission
Laparoscopic surgery to untwist and fix in place, or remove affected ovary by oophrectomy.
What are the complications of ovarian torsion?
Loss of function of that ovary
If the only ovary can lead to infertility and menopause
Necrotic ovary not removed - infection, abscess, sepsis
May rupture, causing peritonitis and adhesions
