o·var·i·an cyst

a cystic tumor of the ovary, either nonneoplastic (follicle, lutein, germinal inclusion, or endometrial) or neoplastic; usually restricted to benign cysts, that is, mucinous serous cystadenoma, or dermoid cysts.
Synonym(s): oophoritic cyst

ovarian cyst

a globular sac filled with fluid or semisolid material that develops in or on the ovary. It may be transient and physiological or pathological. Kinds of ovarian cysts include chocolate cyst, corpus luteum cyst, and dermoid cyst.

ovarian cyst

Functional ovarian cyst; physiologic ovarian cyst Gynecology
A round enclosed space filled with fluid or a semisolid material that develops on the ovary; most OCs are functional and involute spontaneously. Cf Polycystic ovaries.

o·var·i·an cyst

(ō-var'ē-ăn sist)
A cystic tumor of the ovary, either non-neoplastic (follicle, lutein, germinal inclusion, or endometrial) or neoplastic.

Ovarian cyst

A benign or malignant growth on an ovary. An ovarian cyst can disappear without treatment or become extremely painful and have to be surgically removed.

1. a closed epithelium-lined sac or capsule containing a liquid or semi-solid substance. Most cysts are harmless but they occasionally may change into malignant growths, become infected, or obstruct a gland. There are four main types of cysts: retention cysts, exudation cysts, embryonic cysts and parasitic cysts. See also specific locations and organs.
2. a stage in the life cycle of certain parasites, during which they are enveloped in a protective wall. See also cystic.

pertaining to an ovary.

ovarian agenesis
one or both ovaries absent; usually accompanies defects of the tubular reproductive organs.
ovarian anomaly
includes ovarian dysgenesis (see below), agenesis (above) or hypoplasia, as in Swedish Highland cattle.
ovarian bursa
a pouch formed by the mesosalpinx and the mesovarium that encloses the infundibulum of the uterine tube and the ovary. It is shallow in the mare and does not enclose the ovary. It is capacious in sows and deep with a fat-filled wall in the bitch.
ovarian bursitis
inlammation of the ovarian bursa; likely to affect the function of the ovary and ovulation.
ovarian cycle
the cycle of follicle maturation and rupture, then luteinization and regression of the corpus luteum followed by recommencement of the cycle, unless pregnancy intervenes.
ovarian cyclicity
the regular appearance of estrus as an indication of the regular occurrence of estrous cycles.
ovarian cyst
see cystic ovarian disease (below).
cystic ovarian degeneration
persistent cysts derived from ovarian follicles which do not ovulate. Follicular cysts are thin-walled and fluctuant, and often multiple. Luteal cysts have a thick wall of luteal tissue about the cyst, are firm to palpate and do not rupture easily. There is abnormal estral behavior, either anestrus or nymphomania, and diminished fertility.
Cystic corpora lutea form after ovulation has occurred and do not interfere with reproduction. They have a characteristic ovulation papilla.
cystic ovarian disease
common disease of cows, less common in sows, characterized by gross abnormalities of estrus, either anestrus or more frequent and prolonged. In cows the cysts can be palpated per rectum.
ovarian dysgenesis
small, inactive ovaries lacking germ cells such as occur in mares lacking a second X chromosome.
ovarian follicle
see ovarian follicle.
follicular ovarian cyst
see cystic follicle.
ovarian hormones
estrogens, progesterone.
ovarian hypoplasia
functional hypoplasia in immature females and undernourished females of all ages are common findings; in the absence of these risk factors hypoplasia is genetic in origin in Swedish Highland and possibly white Ayrshire cattle.
ovarian imbalance
an alternative name of endocrine dermatoses caused by abnormalities of ovarian function in bitches. Type I, associated with cystic ovaries or functional ovarian tumors, consists of a bilaterally symmetrical alopecia, gynecomastia, enlargement of the vulva, and abnormalities of the estrous cycle. Type II is a bilaterally symmetrical alopecia, sometimes with seborrhea, in spayed bitches. It is responsive to treatment with estrogen. Called also estrogen-responsive dermatosis.
ovarian inflammation
intrafollicular ovarian hemorrhage
hemorrhage into an ovarian follicle occurs in all species during ovulation; also rarely in anovulatory follicles.
luteal ovarian cyst
see luteal cyst.
luteinized ovarian cyst
see luteal cyst.
ovarian neoplasms
includes mostly granulosa cell tumors, but also rarely carcinomas, fibromas, thecomas, sarcomas.
ovarian pain
a rare cause of colic in mares; identifiable by eliciting pain by rectal palpation of ovary.
premature ovarian failure
defective differentiation of ovarian tissue and the patient shows no signs of pubertal estrus until long past the customary age.
ovarian rebound
return of cyclical ovarian activity after a period of inactivity, usually pregnancy and parturition.
ovarian remnant syndrome
the return of estral activity in a desexed female; due to failure to remove all of the ovarian tissue or to dropping, and allowing to implant, a piece of the ovary.
rete ovarii ovarian cyst
a convoluted system of epithelial cell cords and tubules occupying part of the ovarian medulla; the cysts are found mostly in the hilar region of the ovary.
ovarian serous inclusion cyst
similar in size and appearance to, but distinguishable from, ovarian cysts by their intraovarian position; lined by cuboidal epithelium thought to be pinched off from indentations of surface epithelium.
tubular epithelial ovarian cyst
formed from epithelial cells from the surface of the ovary.

Patient discussion about ovarian cyst

Q. What is ovarian cyst and why is it painful? Is that pathological? Dangerous? Need information please.

A. don’t worry- ovarian cyst is usually a natural thin. It shouldn’t be of a problem. And if you need to hear it from a gynecologist:

Q. my little sister have her periode badly.it stay for a months somethimes what can cause that? Since she start having her periode is been a problem and anybody cannot give us a straight answer she's been a hospitolize and had to have blood transfussion she's always anemic and sh'es been putting on pills but her body did not react good to it we had to stop.Sometimes she fells so weak that she pass out.The doctor say she may need to hospitolized again she doenst want to and we dont know how to help her she just wants a normal teenager and get ready to go away to collegebut we are scare that may not happens,she loves school so much and she feltthat she will never be a normal woman like everybody and scare that she may never have children one day i tell her to not be worry about it but i feel helpless.Please tell me what's wrong with her since nobody seems to give us a straight answers.Is follicular cyst of ovaries can put her in so much pain.

A. The menstrual cycle is not the same for every woman. On average, menstrual flow occurs every 28 days (with most women having cycles between 24 and 34 days), and lasts about 4 days. However, there is wide variation in timing and duration that is still considered normal, especially if your periods began within the last few years. Causes:
Anovulation (failure of ovaries to produce, mature, or release eggs)
Endometrial polyps (the endometrium is the inner lining of the uterus)
Endometrial hyperplasia (thickening/build up of the uterine wall)
Endometrial cancer
Uterine fibroids
