GYNO FINAL IMAGES Flashcards
*
Dermoid Tumor
-dermoid mesh
Dermoid Cyst
-tip of the iceburg
Testes
- low level echogenicity
- 7-10 mm diameter
- mediastinum teste and epididymus (not seen until after puberty)
*
Bicornate Uterus
- best seen in trans
- bicornate and didelphys -not associated w/ infertility
- duplicated uterus w/ common cervix
*
Bicornate Uterus
- best seen in trans
- bicornate and didelphys -not associated w/ infertility
- duplicated uterus w/ common cervix
Uterus w/ Fibroids
- fibroid usually has rounded borders
- fibroids are estrogen dependant and grow during pregnancy
- may cause infertility
*
submucosal fibroids
- look how each fibroid interfaces w/ endometrial lining
*
Uterine Polyp
- polyp outlined w/ SIS
- color doppler demonstrating vascular pedicle
*
Uterine Polyp
(on a stalk)
Uterine Synechia
- synechia shows up as linear strands of scar tissue extending from one side of uterus to other
Follicles
- 1st image: follicular phase
- 2nd image: dominant follicle
Polycystic Ovarian Syndrome“string of pearls”
- 12 or more follicles measuring 2-9 mm;
ovarian volume > 10 cm3
- often occurs w/ clinical triad:
- olgiomenorrhea, hirsutism, obesity
- immature follicles continue to produce estrogen and androgen which inhibits pit gland.
- Pit gland produces more LH than FSH –> follicle to remain in arrested state of development- no mature ova released w/ ovulation
- chronic elevation of estrogen
peritoneal inclusion cysts
endometriosis
- most common benign gynecologic disease
- in 10-25% of women w/ gyn disease
- in 40% of women w/ infertility
assess thickness and echogenicity pattern
increased thickness 2-3 mm –> 12-14 mm
- measure long plane
- outer to outer - double layer thickness
- normal pattern - trilaminar
- thin endometrium - < 8mm (in secretory phase)
- -decreased fertility
measuring endometrium
Ovarian Stimulation
- administer clomiphene (Clomid) or gonadotropin (Pergonal) day 3-5 in normal cycle
- enlarges multiple follicles instead of just one dominant follicle
- US monitors # and size of follicles day 8-14 (follicular phase)
- count all follicles > 1cm or 10mm
- optimum follcile size = 15-20 mm
- hCG may be given IM to trigger ovulation w/ retrieval 30-34 hours later
Oocyte retrieval
- oocyte fertilization in dish and incubated for 3 to 5 days before embryo transfer
US guided embryo transfer
Ovarian Hyperstimulation Syndrome
- this is a complication of assisted reproductive technology
- enlarged ovaries, multiple cysts, abd ascites, pleural effusions
- more common w/ PCOS
- mild ovarian enlargement 5- 10 cm

What is seen inside this double decidual sac sign?
yolk sac
interstitial pregnancy
- endometrial cavity line does not enlcose gestational sac
- absence of surrounding myometrium - pregnancy look like it is at the edge of the right side of uterus
- most life threatening
cervical ectopic pregnancy
abdominal ectopic pregnancy
- pregnancy develops w/in the peritoneal cavity
indications for 1st trimester exam
- Confirmation of IUP vs. EUP
- Define cause of bleeding
- Pelvic Pain
- Viability
- # of embryos
- Gestational age
- Detect anomalies
- R/O hydatidform mole
- Adjunct to CVS, amnio, embryo transfer, IUD removal
- **First trimester exam performed only when deemed necessary**
indications for 2nd & 3rd trimester exam
- Gestational Age
- Fetal Growth
- Vaginal Bleeding
- Abd/Pelvic pain
- Incompetent cervix
- Determine fetal presentation
- # fetuses
- Size discrepance to dates
- Pelvic mass
- Suspected hydatidform mole
- Cervical cerclage placement
- R/O ectopic
- Fetal viability
- Uterine abnormality
- Evaluate fetal well-being
- Amniotic fluid
- Placental abruption
- External cephalic version
- Premature rupture membranes and/or labor
- Abnormal chemical markers
- F/U fetal anomaly
- History prev congenital anomaly
- Eval for late to prenatal care
