UT pathology Flashcards

1
Q

How does the uterus develop?

A
  • Paired Mullerian ducts descend into the pelvis at week 13 of fetal life
  • fusion occurs from the inferior (Cx) to the superior (fundus)
  • resorption of the center occurs last

Q

What are the symptoms of leiomyomas?

A
  1. Pain- especially when size increases and with infarction
  2. Menorrhagia - fibroids prevent the efficient contraction of the UT during menses
  3. Infertility - repeat spontaneous abortions (especially with submucous)

27
Q

Beneath the serosa or perimetrium, may be pedunculated and torse(twist) . . . infarct . . . Pain

A

Subserosal

28
Q

Between layer of broad ligament

A

Intraligamentous

29
Q

Sono findings for Leiomyomas

A
  • Well circumscribed , solid mass
  • May be hypoechoic or echogenic and shadows if calcified
  • Usually round
  • Swirled internal architecture
30
Q

Invasion of endometrial glands and stroma into the myometriun

  • may be diffuse or focal
  • Oval not round like a fibroid
A

Adenomyosis

31
Q

Malignant rare tumor of the uterus that develops primarily as a malignancy (not premalignant)

A

Leiomyosarcoma

32
Q

Sono findings of Leiomyosarcoma

A

there is no defining feature sonographically or on MRI

  • these are incidental findings at hystorectomy
  • suspect it with rapid growth of a solid mass
33
Q

Symptoms of adenomyosis

A
  1. pain
  2. Infertility
  3. Menometrorrhagia -UT can’t contract effectively
34
Q

Sono findings of adenomyosis

A
  • oval mass (focal form)
  • UT enlarged (> 14cm)
  • Myometrial cysts (dilated glands that have grown into the myometrium)
  • asymetric thickening of endometrium
  • Mottled, inhomogeneous myometrium
  • “venetian blind” type of shadowing
35
Q

Do sono findings lead to diagnosis of adenomyosis?

A

No, sono findings are suggestive , MRI=diagnostic

36
Q

2nd most common Gyn malignancy in females

A

Cervical cancer

37
Q

Cervical cancer is most common in females of what age?

A

20-30 yrs. old

38
Q

What is the most common symptom for cervical cancer?

A

Post coital bleeding

39
Q

How is cervical cancer diagnosed and treated?

A

Diagnosed with pap smear, colposcopy, cone Bx

Treatment= Conization, LEEP, Hystorectomy ( if advanced)

40
Q

What are the risk factors for cervical cancer

A
  1. Early sexual activity
  2. Multiple sex partners
  3. HPV infection
41
Q

Sono findings for cervical cancer

A
  • Normal if early
  • Enlarged bulking Cx
  • May look like a cervical fibroid
  • Late stage = hydronephrosis (spreads and blocks ureters)
42
Q

Nabothian cysts are

A

Very common, due to obstruction-dilation of endocervical gland and are of no clinical significance

43
Q

Are nabothian cysts measured or counted?

A

No

44
Q

Water in the uterus

A

Hydrometra

45
Q

Causes of hydrometra

A
  • cervical stenosis (lack of estrogen in post menopausal women)
  • pelvic radiation ( hisstory counts)
  • cervical mass
46
Q

How do you measure hydrometra?

A

Anterior and posterior endo linings separately, then add together

  • Do it at the thickest part, usually near the fundus
  • 1 good measurement
47
