Ovarian cystadenomas are a rare form of ovarian cyst.  Most are not dangerous; however, some varieties of cystadenoma can grow extremely large.  Generally, this type of cyst needs to be surgically removed.  Fortunately, this particular type of cyst is unlikely to come back after it’s removed.

Types of Cystadenomas

Most of the time, ovarian cystadenomas are not cancerous.  However, they can grow to an enormous size if left untreated. A cystadenoma will come in one of two types: serous and mucinous.

Serous cystadenomas are the less severe form.  Serous cysts are filled with fluid, generally a thin, watery liquid.  These type of cysts usually remain between two and six centimeters in diameter.  They can be removed surgically through laparascopy.

Mucinous cystadenomas are filled with a thick, mucous like fluid.  These can grow exceptionally large.  Some have been known to weigh as much as 100 pounds.  These need to be removed surgically, as they will continue to grow until they are removed.

Diagnosis and Treatment of Ovarian Cystadenomas

Ovarian cystadenomas are generally discovered during a routine pelvic exam.  The doctor will feel a mass on the ovary and order an ultrasound.  The ultrasound will reveal what type of cyst is present and what it’s filled with.  Most of these masses are not cancerous; however, if the cyst is made of solid material, surgery will generally need to be performed.

To remove a cystadenoma, most doctors will do a laparascopy.  During this procedure, a small incision is cut in the abdomen.  The doctor inserts a narrow tube with a camera and light at the end.  He or she then attempts to remove the cyst.  In many cases, the ovary is removed as well.

If the cyst is over 2.5 centimeters in diameter, then regular surgery will need to be performed.  The doctor will check to make sure that there is no other growths in your abdomen.  If cancer is suspected, a hysterectomy may be performed.
