What is a cyst?
A fluid-filled sac.
If premenopausal MC benign
If postmenopausal MC malignant
When would an ovarian cyst be considered a PCOS?
Ovarian cysts + the following:
Hyperandrogenism
Polycystic ovaries on USS
Anovulation
Sx for ovarian cyst
Mostly aSx but can present with:
1. Pelvic pain (acute pelvic pain usually occurs if there is ovarian torsion, haemorrhage or rupture)
2. Abdominal fullness - early satiety
3. Palpable pelvic mass
4. Bloating
What are the two types of most common functional ovarian cysts?
- Follicular cysts: MC
Cysts grow on ovaries = called follicles → release oestrogen and progesterone → release egg during ovulation → monthly growing follicle = functional cyst - Corpus luteum cysts:
Doesn’t breakdown during menstrual period + gets filled with fluid - commonly occurs in early pregnancy
- Functional ovarian cysts – cysts that develop as part of the menstrual cycle and are usually harmless and short-lived
Which sx would suggest malignancy in ovarian cysts?
Abdominal distension *
Decreased appetite
Weight loss
Abdominal bloating
Ascites
Urinary Sx
Lymphadenopathy
What are the RF for malignancy of ovarian cysts?
Obesity
Smoking
HRT
Late menopause
Early menarche
Not breastfeeding - breastfeeding is protective
Fhx of BCA1or BCA2*
Increased number of ovulation
What is the tumour marker for ovarian cancer?
CA125 - however it’s not sensitive
What enzyme markers should be measured in all women under 40 due to the possibility of germ cell tumours?
Lactate dehydrogenase
Alpha-fetoprotein
hCG
What investigation is done to diagnose ovarian cyst rupture?
1st line - Transvaginal USS
Definitive - laparoscopy
What are the non-malignant causes of a raise in the tumour marker CA125? (4)
Hint: Think of things that can cause peritoneal inflammation.
Fibroids
PIDs and Adenomyosis
Endometriosis
Menstruation
Pregnancy
Liver disease/ascites
IBD
Describe management for ovarian cysts in premenopausal and postmenopausal women
Premenopausal:
If acute pain consider ovarian torsion
<5 cm = Resolves on it’s own
5-7 cm = Yearly USS
>7 cm = MRI scan to rule out cancer
Postmenopausal:
Raised CA125 = 2 week cancer referral
If <5cm = USS every 4-6 months
What’s Meig’s syndrome and how does it present?
Triad:
Benign ovarian cyst + pleural effusion + ascites
What are factors that reduce the number of ovulations experienced?
Late menarche
Early menopause
Pregnancies
Use of COCP pills
What is ovarian torsion?
When ovaries or fallopian tubes twist on connective tissues that support adnexa (blood supply)
What will most likely cause an ovarian torsion?
Ovarian mass >5cm - benign tumours/cysts
Pregnancies
How can ovarian torsion also happen in younger girl before menarche?
Girls have longer infundibulopelvic ligaments that can twist more easily
Describe the progression of an ovarian torsion and how it’s an emergency.
Twist on ovaries and blood supply → ischaemia → persistence → necrosis of ovaries + loss of function
Sx of ovarian torsion
SUDDEN ONSET SEVERE UNILATERAL PELVIC PAIN
N + V
LOC
Diagnosis of ovarian torsion
1st line - Pelvic USS (whirlpool sign - free fluid and oedema in pelvis)
GS (definitive) - laparoscopic surgery
Tx of ovarian torsion
Detorsion
if severe - oophorectomy (removal of ovary)
What is the main Ddx for ovarian torsion?
Ovarian cyst rupture
What is Pelvic Inflammatory Disease (PID)?
Inflammation and infection of organs surrounding the pelvis which spreads from vagina up to cervix leading to tubular infertility.
Define the following:
- endometritis
- Salpingitis
- Oophoritis
- Parametritis
- Infl. of the endometrium (inner lining of the uterus)
- Infl. of the fallopian tubes
- Infl. of the ovaries
- Infl. of the connective tissue surrounding the uterus.
What are the STI causes and non STI causes for PID?
STI: MC
1. Chlamydia Trachomatis*
2. Neisseria Gonorrhoea
3. Mycoplasma Genitalium
Non STI:
1. Gardnerella Vaginalis
2. H. Influenzae
3. E. Coli
