Q

What are the functional ovarian cysts?

A

Benign cysts commonly presenting in premenopausal women, caused by hormonal fluctuations of menopause.

Follicular cysts - developing follicle fails to rupture and release the egg, causing the cyst to remain for a few cycles.

Corpus luteum cysts - when the corpus luteum fails to break down, but instead fills with fluid. They are often seen in early pregnancy.

Q

What blood tests are required for the following scenarios:

a) premenopausal woman with simple ovarian cyst <5cm

b) postmenopausal woman with simple ovarian cyst >5cm

c) women under 40 with complex ovarian mass

A

a) no further investigation

b) CA125 (tumour marker for ovarian cancer)

c) tumour markers for germ cell tumour (LDH, a-FP and HCG)

20
Q

What are the causes of raised CA125?

A

Sensitive for ovarian malignancy, but not specific:
- endometriosis
- fibroids
- adenomyosis
- pelvic infection
- liver disease
- pregnancy

21
Q

When should a woman be urgently referred for suspected ovarian cancer?

A
  • ascites
  • pelvic / abdominal mass
  • aged >50yrs with IBS sx
  • USS suggests ovarian cancer
22
Q

Simple ovarian cysts in premenopausal women can be managed based upon their size:

a) less than 5cm

b) 5cm to 7cm

c) more than 7cm

A

a) no follow-up scan required; resolves within 3 cycles

b) routine referral to gynaecology and yearly ultrasound monitoring

c) consider MRI scan or surgical evaluation

23
Q

How should ovarian cysts in postmenopausal women be managed?

a) raised CA125

b) cysts under 5cm

A

a) two-week wait

b) monitor with ultrasound every 4-6 months

24
Q

What are the complications of ovarian cysts?

A
  • torsion
  • haemorrhage into the cyst
  • rupture
25
Q

What is Meig’s syndrome?

A

The triad of:
- ovarian fibroma
- pleural effusion
- ascites

Removal of the tumour results in complete resolution of the effusion and ascites.

26
Q

What is the risk of malignancy index?

A

A risk stratification toll in patients with suspected ovarian cancer.

RMI = U x M x CA125

27
Q

What is ovarian torsion?

A

Ovary twists in relation to the surrounding connective tissue, fallopian tube and blood supply.

28
Q

What are the risk factors for ovarian torsion?

A
  • benign tumours
  • pregnancy
29
Q

Presentation of ovarian torsion.

A
  • sudden onset severe unilateral pelvic pain
  • constant, progressive pain
  • nausea and vomiting

OE localised tenderness and ?palpable mass.

30
Q

How should ovarian torsion be investigated?

A
  • transvaginal ultrasound
  • Doppler ultrasound

Definitive diagnosis is via laparoscopic surgery.

31
Q

Management of ovarian torsion.

A

Explorative laparoscopic surgery to diagnose and:
- detorsion
- oophorectomy

32
Q

Complications of ovarian torsion.

A

Infection > abscess > sepsis

Rupture > peritonitis > adhesions

Can result in loss of function in that ovary, but the other ovary can usually compensate so fertility is not typically affected.

33
Q

What is dysmenorrhoea?

a) primary

b) secondary?

A

Painful periods - the most common gynaecological symptom.

a) menstrual pain occurring with no underlying pelvic pathology.

b) menstrual pain that occurs with associated pelvic pathology.

34
Q

What is the physiology behind dysmenorrhoea?

A

In the absence of fertilisation, the corpus luteum regresses, and there is a decline in oestrogen and progesterone production.

The endometrial cells are sensitive to progesterone withdrawal, and respond with prostaglandin release. The effects of which:
- spiral artery vasospasm leading to ischaemic necrosis and shedding of the superficial layer of the endometrium
- increased myometrial contractions

Primary dysmenorrhoea is thought to occur secondary to excessive release of prostaglandins by endometrial cells.

35
Q

Risk factors for primary dysmenorrhoea.

A
  • early menarche
  • long menstrual phase
  • heavy periods
  • smoking
  • nuliparity
36
Q

Presentation of dysmenorrhoea.

A
  • lower abdominal / pelvic pain
  • radiates to lower back or anterior thigh
  • crampy in nature
  • lasts 48-72 hours around the menstrual period

Associated symptoms:
- malaise
- nausea
- vomiting
- diarrhoea
- dizziness

37
Q

Examination findings in primary dysmenorrhoea.

A

Abdominal and pelvic examinations are usually unremarkable.

Uterine tenderness may be present.

38
Q

Differential diagnoses for dysmenorrhoea.

A

Primary dysmenorrhoea is a diagnosis of exclusion. Therefore, other diagnoses to consider at the main causes of secondary dysmenorrhoea:

  • endometriosis
  • adenomyosis
  • pelvic inflammatory disease
  • adhesions

Non-gynaecological differentials include IBD and IBS.

39
Q

How can primary dysmenorrhoea be managed?

A
  • smoking cessation
  • NSAIDs +/- paracetamol
  • COCP / IUS
  • local application of heat
40
Q

What is adenomyosis?

A

Invasion of endometrial tissue inside the myometrium.

41
Q

Presentation of adenomyosis.

A
  • dysmenorrhoea
  • menorrhagia
  • dyspareunia

It may also present with infertility or pregnancy-related complications.

42
Q

Examination findings of adenomyosis.

A
  • enlarged / tender uterus
43
Q

How can adenomyosis be investigated?

A

First line: transvaginal ultrasound

Gold standard: histological examination of the uterus after hysterectomy*.

44
Q

Management of adenomyosis.

A

Symptomatic relief: Tranexamic acid and Mefenamic acid

Management when contraception is wanted or acceptable:
- IUS
- COCP
- cyclical POP

Specialist intervention may include:
- GnRH analogues (induce menopause like status)
- endometrial ablation
- uterine artery embolisation
- hysterectomy

45
Q

What are some complications of adenomyosis?

A
  • infertility
  • miscarriage
