Ovarian & uterine disease Flashcards
1
Q
Ovarian Cysts: Definition
A
A fluid filled or semiliquid filled sac which forms on or inside an ovary
Although anxiety provoking most are benign
Many resolve without surgery
Can form at any stage of life: infancy to menopause
2
Q
Ovarian Cysts: Etiology
A
functional cysts
Theca Lutein cysts
3
Q
What are 2 examples of functional cysts
A
Follicular cysts
Most Common, typically asymptomatic, 3-15cm
Corpus luteal cysts
3cm, dull pelvic pain
4
Q
Theca- Lutein cysts
A
In molar pregnancy, choriocarcinoma or fertility therapy
Bilateral, massive ovarian enlargement, prone to torsion/hemorrhage/rupture
5
Q
What are follicular cysts?
A
Follicle fails to rupture Often asymptomatic Usually a simple, unilocular cyst Size range 3 -15 cm Often regresses spontaneously More likely to rupture
6
Q
What are corpus luteum cysts?
A
Failure of corpus luteum to regress in 14 days Usually smaller 3 – 6 cm Firm or solid More likely to cause pain Delayed menses
7
Q
Functional Cysts may what?
A
Rupture
Become hemorrhagic
Increase in pain
Peritoneal signs
8
Q
How would you diagnose a functional cyst?
A
CBC
Ultrasound
If unilocular and <10 cm in size -risk of malignancy is 0.1%
50% to 70% will resolve

A
Blood-filled cysts from the ectopic endometrium
“chocolate cysts”
Associated with endometriosis:
Dysmenorrhea, menorrhagia, dyspareunia
14

24
Q
Ovarian Torsion Dx and treatment
A
Testing
Ultrasound with color doppler
Treatment: Surgical
Removal of ovary (oophorectomy), untwisting also possible if done immediately
25
5 labs that should be done for ovarian cysts
```
Urine pregnancy test
CBC: check for bleeding/infection
Urinalysis
Cancer antigen 125
Endocervical swabs: PID check for chlamydia/gonorrhea
```
26
Cancer antigen 125
6% can be positive in healthy patients
Most useful in combination with ultrasound
Do not draw in acute care settings, elevated in cyst rupture, infections, hemorrhage, endometriosis
27
Ultrasonography
Primary tool for cyst evaluation
Can show morphology
Can show resolution of cyst
Simple: thin walled, uniform, 2.5 to 15cm in diameter
Complex: multilocular, thick walled, projections into lumen
Ovarian torsion: ovarian edema from blocked lymphatic drainage
28
What are the 2 types of ultrasonography imaging for ovarian cysts
Endovaginal
Detailed morphologic examination of pelvic structures
Uses a handheld probe inserted into the vagina
Transabdominal
For evaluating large masses
29
Ovarian cyst treatment for "most patients" and for "fetal and neonatal cysts"
Most patients with simple ovarian cysts require no treatment, resolve in about 60 days
Fetal and neonatal cysts:
Ovarian cyst most frequent abdominal tumor 30%
Most are small and involute within first few months of life
Management: serial ultrasounds
30
Treatment of ovarian cysts in pregnancy
Most resolve by gestational age 14 -16 weeks
If large mass persists, and ultrasound findings are not suggestive of malignancy, may be watched
If symptomatic, pain, or rapid growth: surgery is considered
31
treatment of ovarian cysts in Post menopausal women <8 cm
asymptomatic simple cysts
< 8cm on ultrasound, normal CA125
Repeat ultrasound in 8-12 weeks
32
treatment of ovarian cysts in Post menopausal women <5cm
Asymptomatic <5cm cyst:
Repeat ultrasound in 4-6 weeks with CA125 study
Half resolve in 2 months
If rising CA125 or increase in cyst size, consider surgery
Follow up is important, risk of malignancy rises from 13% in premenopausal to 45% in postmenopausal patients
33
When is Laparotomy and laparoscopy the preferred treatment for ovarian cysts?
For persistent simple ovarian cysts >5-10cm
For complex ovarian cysts
Confirm diagnosis
Assess if appears malignant
Obtain fluid
Remove cyst with or without ovary
Assess opposite ovary and other abdominal organs
