follicular cyst

Gynaecology
The most common cyst of the ovary, which develops when ovulation does not occur and an egg-bearing follicle does not rupture and release the egg, but rather continues to grow, becoming a thin-walled, serous fluid-filled cyst, measuring up to 5 cm and lined by granulosa cells.

Clinical findings
Usually asymptomatic; less commonly (in about 1/4 of cases), causes sharp unilateral pain (“mittelschmerz”) in the middle of the menstrual cycle, coinciding with ovulation.

Diagnosis
Ultrasonography.

Oral
Dentigerous cyst, see there.

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
