Hi There
did you have a specific question?
this is from wikipedia http://en.wikipedia.org/wiki/Ovarian_cyst
An ovarian cyst is 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. An ovarian cyst can be as small as a pea, or larger than a cantaloupe.
Most ovarian cysts are functional in nature, and harmless (benign).[1] In the US, ovarian cysts are found in nearly all premenopausal women, and in up to 14.8% of postmenopausal women.
Ovarian cysts affect women of all ages. They occur most often, however, during a woman's childbearing years.
Some ovarian cysts cause problems, such as bleeding and pain. Surgery may be required to remove cysts larger than 5 centimeters in diameter
Types
[edit] Functional cysts
Some, called functional cysts, or simple cysts, are part of the normal process of menstruation. They have nothing to do with disease, and can be treated. There are 3 types, Graafian, Luteal, and Hemorrhagic. These types of cysts occur during ovulation. If the egg is not released, the ovary can fill up with fluid. Usually these types of cysts will go away after a few period cycles.
[edit] Graafian follicle cyst
One type of simple cyst, which is the most common type of ovarian cyst, is the graafian follicle cyst, follicular cyst, or dentigerous cyst. This type can form when ovulation doesn't occur, and a follicle doesn't rupture or release its egg but instead grows until it becomes a cyst, or when a mature follicle involutes (collapses on itself). It usually forms during ovulation, and can grow to about 6cm (2.3 inches) in diameter. It is thin-walled, lined by one or more layers of granulosa cell, and filled with clear fluid. Its rupture can create sharp, severe pain on the side of the ovary on which the cyst appears. This sharp pain (sometimes called mittelschmerz) occurs in the middle of the menstrual cycle, during ovulation. About a fourth of women with this type of cyst experience pain. Usually, these cysts produce no symptoms and disappear by themselves within a few months. Ultrasound is the primary tool used to document the follicular cyst. A pelvic exam will also aid in the diagnosis if the cyst is large enough to be seen. A doctor monitors these to make sure they disappear, and looks at treatment options if they do not
Corpus luteum cyst
Another is a corpus luteum cyst (which may rupture about the time of menstruation, and take up to three months to disappear entirely). This type of functional cyst occurs after an egg has been released from a follicle. The follicle then becomes a secretory gland that is known as the corpus luteum. The ruptured follicle begins producing large quantities of estrogen and progesterone in preparation for conception. If a pregnancy doesn't occur, the corpus luteum usually breaks down and disappears. It may, however, fill with fluid or blood, causing the corpus luteum to expand into a cyst, and stay on the ovary. Usually, this cyst is on only one side, and does not produce any symptoms.
It can however grow to almost 10cm (4 inches) in diameter and has the potential to bleed into itself or twist the ovary, causing pelvic or abdominal pain. If it fills with blood, the cyst may rupture, causing internal bleeding and sudden, sharp pain. The fertility drug clomiphene citrate (Clomid, Serophene), used to induce ovulation, increases the risk of a corpus luteum cyst developing after ovulation. These cysts don't prevent or threaten a resulting pregnancy.[10][11] Women on birth control pills usually do not form these cysts; in fact, preventing these cysts is one way the combined pill works.[12] In contrast, the progesterone-only pill can cause increased frequency of these cysts.
Hemorrhagic cyst
A third type of functional cyst, which is common, is a Hemorrhagic cyst, which is also called a blood cyst, hematocele, and hematocyst.[13] It occurs when a very small blood vessel in the wall of the cyst breaks, and the blood enters the cyst. Abdominal pain on one side of the body, often the right side, may be present. The bleeding may occur quickly, and rapidly stretch the covering of the ovary, causing pain. As the blood collects within the ovary, clots form which can be seen on a sonogram.[14][15] Occasionally hemorrhagic cysts can rupture, with blood entering the abdominal cavity. No blood is seen out of the vagina. If a cyst ruptures, it is usually very painful. Hemorrhagic cysts that rupture are less common. Most hemorrhagic cysts are self-limiting; some need surgical intervention. Even if a hemorrhagic cyst ruptures, in many cases it resolves without surgery. Patients who don't require surgery will experience pain for 4 - 10 days after, and may require several days rest. Studies have found that women on tetracycline antibiotics recover 25% earlier than the majority of patients, a surprising correlation found in 2004. Sometimes surgery is necessary,[16][17] such as a laparoscopy ("belly-button surgery" that uses small tools inserted through one or more tiny slits in the abdomen).[18]
