Ovarian Tumor

Question 0

Stroma ovarii?

Answer 0

Benign cystic teratoma containing thyroid tissue, which can cause hyperthyroid

Question 1

Most common ovarian tumor in women under 30? (Both names)

Over 30?

Answer 1

Dermoid cyst (benign cystic teratoma)

Epithelial ovarian tumors

Question 2

Most common type of ovarian malignancy?

Answer 2

Epithelial ovarian tumor - Neoplasm arising from the outer layer of the ovary

Question 3

Functional ovarian cyst?

Answer 3

Physiologic cysts of the ovary, which occur in reproductive-aged women

Question 4

Ultrasound features of dermoid cysts?

Answer 4

1. hypoechoic area
2. Hyperechoic band-like strand in hypoechoic medium
3. cystic structure with a fat fluid level

Question 5

Dermoid cyst – typical initial symptom? Most frequent complication? Other complications?

Answer 5

Severe acute abdominal pain; torsion

Rupture, chemical peritonitis

Question 6

Chemical peritonitis? Treatment?

Answer 6

spilling the tumor contents into the peritoneal cavity

Cystectomy or unilateral oophorectomy

Question 7

Immature teratoma? Typical age?

Answer 7

Contain all three germ layers in addition to immature embryonal structures

First and second decade of life

Question 8

Malignant teratomas contain? Tumor grade dependent on?

Tx?

Answer 8

Immature neural elements (quantity determines the dreamed of tumor)

Unilateral Salpingo-oophorectomy

Question 9

Struma ovariaii – on MRI see?

Answer 9

Complex multiloculated mass with thick septa (which are multiple large thyroid follicles)

Question 10

Types of epithelial ovarian tumors?

Answer 10

Serious
Mucinous
Endoetroid
Brenner
Clear cell

Question 11

Types of germ cell tumors?

Answer 11

Dysgerminoma
Endodermal sinus tumor
Embryonal carcinoma
Polyembryoma
Choriocarcinoma
Teratoma

Question 12

Most common type of epithelial ovarian tumor? Location?

Answer 12

Serous; unilateral

Question 13

Mucinous tumors – size? Rupture may lead to? Tx? Associated symptoms? Marker?

Answer 13

Large; pseudomyxoma peritoneii (Mucinous material spills out into intra-abdominal cavity)

Surgical staging, chemotherapy

Malignant ascites, spread to small bowel/momentum, lymphatic extension

CA-125

Question 14

CA-125 postmenopause?

Answer 14

More specific for epithelial ovarian tumors than during reproductive years

Question 15

Adnexal mass – if reproductive age, management based on size?

Answer 15

<5 cm – suggests a functional cyst

Between 5-8 cm – use ultrasound to distinguish

Over 8 cm – likely tumor, should be explored

Question 16

30 y/o Patient with 6 cm adnexal mass – distinguish between functional versus neoplasm how?

Answer 16

Septations, solid components, or excrescences (Growth on surface or inner lining) are consistent with neoplastic process

Question 17

Evaluation of adnexal mass if not reproductive age?

Answer 17

Prepubertal – if mass greater than 2 cm, operate

menopausal – If mass greater then 4-5 cm, operate

Question 18

Granulosa-theca cell tumors versus Sertoli-leydig cell tumors?

Answer 18

Both are solid tumors; produce estrogens versus androgens

Question 19

Find very large tumor on ovary – likely type?

Answer 19

Mucinous tumor
