A cyst is a closed pocket or pouch of tissue. It can be filled with air, fluid, pus, or other material. A vaginal cyst is a closed sac on or under the vaginal lining.
Inclusion cyst; Gartner's duct cyst
There are several types of vaginal cysts.
Vaginal cysts usually do not cause symptoms, although there may be a soft lump felt in the vaginal wall or protruding from the vagina. Cysts range in size from the size of a pea to that of an orange.
Some women with vaginal cysts may have discomfort during sex or trouble inserting a tampon.
If the cyst is located under the bladder or urethra, X-rays may be required to be sure the cyst does not involve these structures.
The only treatment needed may simply involve routine exams and watching the cyst for growth and other changes.
Opening and draining the cyst does not usually work well and may lead to infection.
Surgery may be needed if the cyst is causing symptoms. However, this can sometimes be a very involved surgery and is not recommended unless you are having more severe symptoms.
The outcome is generally good. Frequently cysts remain small and require no treatment. When surgically removed, the cysts usually do not return.
There are usually no complications from the cysts themselves. A surgical excision procedure carries a small risk of complications depending on where the cyst is located in relation to other structures.
Call your health care provider if a lump is felt inside the vagina or protruding from the vagina.
