ovarian cyst

(noun)

Any collection of fluid, surrounded by a very thin wall, within an ovary; any ovarian follicle that is larger than about two centimeters is termed an ovarian cyst.

Examples of ovarian cyst in the following topics:

  • Ovarian Cysts

    • An ovarian cyst is a fluid-filled vacuole within or on an ovary.
    • Any ovarian follicle that is larger than about two centimeters is termed an ovarian cyst.
    • Ovarian cysts affect women of all ages.
    • Some ovarian cysts cause problems, such as bleeding and pain.
    • About 95% of ovarian cysts are benign .

  • Abdominopelvic Regions

    • Pain in this region is generally associated with colitis (inflammation of the large intestine) as well as pelvic inflammatory disease and ovarian cysts in females.

  • Ovarian Cancer

    • Ovarian cancer arises from the epithelial layer of the ovary and in some cases, the fallopian tube.
    • Ovarian cancer is a cancerous growth arising from the ovary.
    • In most cases, the exact cause of ovarian cancer remains unknown.
    • The risk of developing ovarian cancer appears to be affected by several factors.
    • The more children a woman has, the lower her risk of ovarian cancer.

  • Polycystic Kidney Disease

    • PKD is characterized by the presence of multiple cysts (hence, "polycystic"), typically in both kidneys.
    • The cysts are numerous and are fluid-filled, resulting in massive enlargement of the kidneys.
    • ADPKD is characterized by progressive cyst development and bilaterally enlarged kidneys with multiple cysts.
    • Under the function of gene defect, epithelial cells of renal tubule turn into epithelial cells of cyst wall after phenotype change and begin to have the function of secreting cyst fluid, which leads to continuous cysts enlargement.
    • The major extrarenal complications of ADPKD include cerebral aneurysms, hepatic cysts, pancreatic cysts, cardiac valve disease (especially mitral valve prolapse), colonic diverticula, and aortic root dilatation.

  • Ovaries

    • The ovary (for a given side) is located in the lateral wall of the pelvis in a region called the ovarian fossa.
    • The ovaries are not attached to the outer layer of the uterus via the ovarian ligaments.
    • In humans the paired ovaries lie within the pelvic cavity, on either side of the uterus, to which they are attached via a fibrous cord called the ovarian ligament.
    • The uterine extremity points downward and is attached to the uterus via the ovarian ligament.
    • The developing egg cell (or oocyte) grows within the environment provided by ovarian follicles.

  • Ovarian Cycle

    • The rise in FSH levels recruits five to seven tertiary-stage ovarian follicles (this stage follicle is also known as a Graafian follicle or antral follicle) for entry into the menstrual cycle.
    • Ovulation is the process in female's menstrual cycle by which a mature ovarian follicle ruptures and discharges an ovum (also known as an oocyte, female gamete, or casually, an egg).
    • These falling levels of ovarian hormones cause increased levels of FSH, which begins recruiting follicles for the next cycle.
    • The ovarian cycle is the series of changes that occur in the ovary during the menstrual cycle that cause maturation of a follicle, ovulation, and development of the corpus luteum.

  • Male and Female Gonads

    • The ovary is a paired, ovum-producing, reproductive organ located in the lateral wall of the pelvis in a region called the ovarian fossa.
    • The ovaries are not attached to the fallopian tubes but to the outer layer of the uterus via the ovarian ligaments.
    • The left ovary is visible above the label ovarian arteries.

  • Fibrocystic Disease of the Breasts

    • Years of such fluctuations eventually produce small cysts and/or areas of dense or fibrotic tissue.
    • Multiple small cysts and an increasing level of breast pain commonly develop when a woman hits her 30's.
    • Larger cysts usually do not occur until after the age of 35.

  • Galactosemia and Glycogen Storage Disease

    • In individuals with galactosemia, the enzymes needed for further metabolism of galactose are severely diminished or missing entirely, leading to toxic levels of galactose 1-phosphate in various tissues as in the case of classic galactosemia, resulting in hepatomegaly (an enlarged liver), cirrhosis, renal failure, cataracts, brain damage, and ovarian failure.
    • Even with an early diagnosis and a restricted diet, however, some individuals with galactosemia experience long-term complications such as speech difficulties, learning disabilities, neurological impairment (e.g. tremors, etc. ), and ovarian failure in females.

  • Hormonal Regulation of the Female Reproductive Cycle

    • The rise in FSH levels recruits tertiary-stage ovarian follicles (antral follicles) for entry into the menstrual cycle.
    • Ovulation is the process in a female's menstrual cycle by which a mature ovarian follicle ruptures and discharges an ovum (oocyte).
    • In the pre-ovulatory phase of the menstrual cycle, the ovarian follicle will undergo cumulus expansion, which is stimulated by FSH.
