Ovarian Pathology Flashcards
Remnants of the embryonic ducts, also called cysts of Morgagni, never surrounded by ovarian tissue
Paraovarian cysts
Located midline in the anterior abdominal wall between umbilicus and bladder.
Urachal cyst
Multiple, bilateral cysts caused by excessive amounts of hCG and may rupture, hemorrhage or torsion
Theca Lutean Cysts
Unopposed estrogen with no surge of LH with many immature follicle that never mature or rupture, increased androgen secretion
PCOS
The most extreme form of PCOS
Hyperthecosis or thecosis
Acute sharp pain that is usually associated with ovarian masses
Torsion
Incomplete vs complete torsion
Incomplete: large, fluid filled ovaries with multiple cysts
Complete: increased or decreased echotexture due to infarct or hemorrhage
3 types of neoplastic tumours
- epithelial
- germ cell
- connective tissue/stromal
7 types of epithelial tumours
- serous cystadenoma
- serous cystadenocarcinoma
- mucinous cystadenoma
- mucinous cystadenocarcinoma
- Endometroid
- Clear cell carcinoma
- Brenner’s tumour
Common, benign, simply cystic tumour
Serous cystadenoma
Most common malignant ovarian cancer, large, ascites, cystic with irregular texture and walls/thick septations
Serous cystadenocarcinoma
Benign, unilateral cystic mass with low level echoes/complex looking, usually very large and may rupture due to size
Mucinous cystadenoma
Rare, malignant neoplasm with complex ascites, risk of pseudomyxoma
Mucinous cystadenocarcinoma
Usually malignant, large, complex looking, menopausal age group, associated with endometrial cancer
Endometrioid carcinoma
Complex malignant mass, also called mesonephoid, Müllerian duct origin
Clear cell carcinoma
