Definition: An ovarian cyst is any collection of fluid, surrounded by a very thin wall, within an ovary.
Most ovarian cysts are functional in nature and harmless (benign). In the US, ovarian cysts are found in nearly all premenopausal women, and in up to 14.8% of postmenopausal women.

Types
ovarian functional cysts
- ovarian luteinic cyst
- ovarian follicular cyst (ovarian functional cyst )
- Any ovarian follicle that is larger than about two centimeters is termed an ovarian follicular cyst.
- Some ovarian cysts cause problems, such as bleeding and pain.
- Surgery may be required to remove cysts larger than 5 centimeters in diameter.
ovarian non-functional cysts
- epithelial inclusion cyst
-
ovarian endometriotic cyst (or chocolate cyst of ovary, endometrioma, endometrioid cyst, endometrial cyst).
- It is caused by endometriosis.
- It formed when a tiny patch of endometrial tissue (the mucous membrane that makes up the inner layer of the uterine wall) bleeds, sloughs off, becomes transplanted, and grows and enlarges inside the ovaries.
ovarian cystic epithelial tumors
cystic ovarian germ cell tumors
- cystic ovarian teratoma
Classification
non-neoplastic ovarian cysts and functional ovarian cysts
- follicular cyst (cysic follicle )
- multiple luteinized follicular cysts (theca-lutein cysts ; hyperreactio luteinalis )
- large solitary luteinized follicular cyst
- corpus luteum cysts
- polycystic ovaries (sclerocystic ovaries )
ovarian cystic tumors
- ovarian serous cystadenoma
- ovarian mucinous cystadenoma
- cystic ovarian Sertoli-Leydig cell tumor
- cystic ovarian teratoma
- ovarian dermoid cyst
- cystic struma ovarii
ovarian inclusion cysts
- surface epithelial inclusion cysts
developmental cysts
- hydatids of Morgagni
- parovarian cysts and paratubal cysts
cysts of the rete ovarii
ovarian epidermoid cysts
ovarian endometriotic cyst
According to the lining cells
granulosa and theca layers: luteinic cyst
nonluteinized granulosa cells: follicular cyst
luteinized granulosa cells: luteinic cyst
ciliated cylindric epithelial cells: serous cystadenoma
mucinous cylindric epithelial cells: mucinous cystadenoma
Miscellaneous
