Chapter 30 Pathology----GYN Flashcards

1
Q
  • These are caused by continued hormonal stimulation of a FOLLICLE that does not rupture at ovulation. Usually disappears within a few weeks.
  • usually 3-5 cm in diameter, can get to be 10 cm—when hemorrhage occurs, there may be internal echoes

What age group does this occur most in? (reproductive or postmenarche?)

Why should you do a repeat study after 3-4 weeks??

A

Follicular cysts

reproductive age group

Because ovulation often takes place on alternate sides. By doing a repeat study, we can document that the mass has disappeared

Q

a sequelae of pelvic inflammatory disease or endometriosis involving the FALLOPIAN tube.

Sonographically–tube folds over on itself forming a funnel-shaped or kinked structure

CLUE: (fluid build up in the fallopian tubes)

A

Hydrosalpinx

Q
  • a disease state that occurs in the reproductive years
  • caused by implantation of endometrial tissue in ABNORMAL locations outside of the endometrium. This ectopic endometrial tissue responds to cyclic ovarian hormones and bleeds as if it was located w/i uterus.
  • Endometrial cysts (endometerioma) may develop in areas of bleeding.
  • The small cysts are BLEBS
  • The larger are called CHOCOLATE CYSTS (hence the blood and color)

Often seen in which age group? (reproductive or postmenopausal or both?)

16
Q

similar to the mucinous form of cystadenoma but the septa is THINNER and papillary material ( the solid mass within the septa) is less commmon

May be malignant if there are poorly defined walls, large amounts of solid tissue and ascites

A

SEROUS cystadenoma and cystadenocarcinoma

17
Q

-occur in females 10-30 with a variety of sonographic appearances.

1) Mainly CYSTIC, containing echogenic area w/ shadowing because of a hairball, teeth or fat
2) Complex internal structure–echogenic areas because of fat, hair, or bone w/ shadowing
3) “ICEBERG” appearance–dense echogenic material within mass shadows the bulk of lesion (use endovaginal to help)
4) echogenic mass—this may blend with bowel, but the lesions presence will be revealed by indentation of bladder
5) fluid-filled level—may lie posteriorly or anteriorly–sometimes there is a hariball floating at the top(appearing mobile echogenic casting a shadow)
6) multiple thick septa within round cyst

—another word for dermoid

A

Cystic teratomas

18
Q

one of the LEADING causing of death in women—Ultrasound cannot fully diagnose the malignancy of the cancer. Malignancy is suggested with:

  1. poor definition of borders (tumor spread)
  2. multiple unconfined cystic areas containing irregulary shaped solid material
  3. Malignant ascites–loculated fluid between loops of bowel w/ peritoneal metastases
  4. solid ovarian mass
  5. bilateral nature.
  6. low-resistance
A

Ovarian cancer

19
Q
  • frequently located in ovary.
  • cystic mass w/ internal echoes
  • ecdhogenic border
  • echogenicity is similar to dermoid
A

Endometrioma

20
Q
  • looks similar to endometrioma
  • contains low level echoes w/o the same evenness of texture
  • the “ring of fire” will disappear after the hemorrhage has been there for a while.
  • follow up after 6 weeks

Why is there a follow up after 6 weeks?

A

Corpus Luteum hemorrhage

-Helps distinguish between corpus luteum w/ hemorrhage or endometrioma. The corpus luteum will spontaneously disappear after some weeks.

21
Q
  • Solid ovarian mass
  • tends to be large and similar to fibroids
  • calcification can occur
  • Meigs syndrome may be seen.

What age group does it affect?
(Menopausal and postmenopausal or both)

A

Fibroma

Menopausal and postmenopausal

22
Q
  • associated with fibroma

- can cause ascites and pleural effusion

A

Meigs Syndrome

23
Q

Why is it important to look at the kidneys when examining a patient with a large pelvic mass?

A

To rule out hyndronephrosis caused by pressure on ureters

- To rule out a pelvic kidney (examine normal sites)

24
Q

Where is the most common site for metastatic lesions from pelvic masses?

A

Peritoneum, para-aortic nodes, and liver.

25
Q

Why is it important to make sure the patient voids completely?

A

An enlarged bladder can be confused with a cyst.

26
Q

An ovarian cyst located in the midline anterior to the uterus can be mistaken for the bladder..why?

A

The cyst may may compress the bladder, making it uncomfortable when the bladder is filled

27
Q

_____ to _____ milliliters of fluid is normal in women in the reproductive age. This can also be derived from follicular rupture

A

10-15 mm

28
Q

The ______ and the ______ muscles may be mistaken with a pelvic muscle.

A

the iliopsoas and piriform muscles

29
Q

Why are the ovaries sometimes hard to find after a hysterectomy?

A

The ovaries may fall together in the center of pelvis or be pulled laterally

30
Q

GUT VERSUS OVARY: (no answer, just study this)

When no follicles are seen in postmenopausal women, an indolent loop of feces/bowel may be confused w/ an ovary. Watch for peristalis

A

Pitfall

31
Q

FIBROID VS OVARIAN MASS:

-If amass lies adjacent to ovary, it may be hard to distinguish between fibroid and solid intraovarian mass such as a fibroma.

**What should we do in this case?? Why should we use doppler?

A

Push the vaginal probe between mass and uterus to see if they can be seperated. This gap between the two structures needs to be seen at all sites for a mass to be either ovarian or pedunculated fibroid.

To see whether there are vessels extending from uterus to mass.

32
Q

What are some questions helpful to ask to perform a quality sonogram?

A
  1. date of LMP
  2. are the cycles regular and last how long?
  3. If patient had hysterectomy, does she know when she ovulates?
  4. How long ago did she last menstruate
  5. pelvic surgeries?
  6. how many children does she have?
  7. Pain, and where is it located?
  8. any hormone replacement?
