An ovarian cyst is a fluid-filled sac in the ovary. The most common type of ovarian cyst is a follicular cyst. This results from the growth of a follicle, or 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. This usually resolves over the course of days to months.
Other types of ovarian cysts include: - Hemorrhagic or endometrioid cysts, which contain blood - Dermoid cysts (or ovarian teratomas). These are usually benign tumors which contain many different body tissues such as hair, teeth, bone, cartilage, etc.
Most ovarian cysts exist without being noticed and resolve without you ever knowing that it was there. When a cyst causes symptoms, pain is by far the most common presentation. This pain is usually caused when the cyst ruptures, or when it undergoes rapid growth, or twisting of the cyst around its blood supply.
The diagnosis of an ovarian cyst generally confirmed by ultrasound.
