Follicular Cyst of the Ovary (Ovarian Cyst)
A follicular cyst of the ovary, aka ovarian cyst, is a fluid-filled sac in the ovary. It is the most common type of ovarian cyst which results from the growth of a follicle. A follicle is the fluid-filled cyst that contains an egg. In some cycles. This follicle grows larger that normal and does not rupture to release the egg. Normally it resolves over the course of days to months. Most ovarian cysts are never noticed and resolve without ever knowing they were there. When a cyst causes symptoms, pain is by far the most common presentation. The pain from an ovarian cyst can be caused from rupture of the cyst, rapid growth of the cyst or stretching, bleeding into the cyst, and twisting of the cyst around its blood supply. The diagnosis of an ovarian cyst is usually made by ultrasound. The treatment of these tumors depends on the woman’s age, the size of the cyst, and its appearance on ultrasound. If the tumor is causing severe pain, or if it is not resolving or is suspicious in any way, then it can be removed through laparoscopy or, if needed, through an open laparotomy (“bikini incision”). The outcome is usually excellent.
