Flashcards in Ovarian Tumor Deck (20)
Most common ovarian tumor in women under 30? (Both names)
Dermoid cyst (benign cystic teratoma)
Epithelial ovarian tumors
Benign cystic teratoma containing thyroid tissue, which can cause hyperthyroid
Most common type of ovarian malignancy?
Epithelial ovarian tumor - Neoplasm arising from the outer layer of the ovary
Functional ovarian cyst?
Physiologic cysts of the ovary, which occur in reproductive-aged women
Ultrasound features of dermoid cysts?
1. hypoechoic area
2. Hyperechoic band-like strand in hypoechoic medium
3. cystic structure with a fat fluid level
Dermoid cyst – typical initial symptom? Most frequent complication? Other complications?
Severe acute abdominal pain; torsion
Rupture, chemical peritonitis
Chemical peritonitis? Treatment?
spilling the tumor contents into the peritoneal cavity
Cystectomy or unilateral oophorectomy
Immature teratoma? Typical age?
Contain all three germ layers in addition to immature embryonal structures
First and second decade of life
Malignant teratomas contain? Tumor grade dependent on?
Immature neural elements (quantity determines the dreamed of tumor)
Struma ovariaii – on MRI see?
Complex multiloculated mass with thick septa (which are multiple large thyroid follicles)
Types of epithelial ovarian tumors?
Types of germ cell tumors?
Endodermal sinus tumor
Most common type of epithelial ovarian tumor? Location?
Mucinous tumors – size? Rupture may lead to? Tx? Associated symptoms? Marker?
Large; pseudomyxoma peritoneii (Mucinous material spills out into intra-abdominal cavity)
Surgical staging, chemotherapy
Malignant ascites, spread to small bowel/momentum, lymphatic extension
More specific for epithelial ovarian tumors than during reproductive years
Adnexal mass – if reproductive age, management based on size?
<5 cm – suggests a functional cyst
Between 5-8 cm – use ultrasound to distinguish
Over 8 cm – likely tumor, should be explored
30 y/o Patient with 6 cm adnexal mass – distinguish between functional versus neoplasm how?
Septations, solid components, or excrescences (Growth on surface or inner lining) are consistent with neoplastic process
Evaluation of adnexal mass if not reproductive age?
Prepubertal – if mass greater than 2 cm, operate
menopausal – If mass greater then 4-5 cm, operate
Granulosa-theca cell tumors versus Sertoli-leydig cell tumors?
Both are solid tumors; produce estrogens versus androgens
