Understanding Different Types of Ovarian Cysts
There are many types of ovarian cysts. While most are benign and often resolve on their own, some can cause pain, grow over time, or require surgical treatment. Knowing the differences can help you understand your diagnosis and options for care.
Types of Ovarian Cysts
Common ovarian cysts explained, with symptoms and treatment options.
Simple Cyst
The most common ovarian cyst is a functional (simple) cyst, which is a fluid-filled cyst — like a balloon on the ovary.
These cysts usually resolve spontaneously. Sometimes they can rupture suddenly, causing severe pain.
Dermoid Cyst
Cystadenoma
A cystadenoma is a benign ovarian cyst which may be mucinous or serous.
These cysts typically grow slowly over time.
They are treated with laparoscopic removal, with particular care taken to preserve normal ovarian tissue.
Endometrioma
An endometrioma is a cyst of the ovaries caused by endometriosis.
It is also known as a “chocolate cyst”, because it is filled with thick brown fluid (old blood).
Torsion of a Cyst
Sometimes an ovarian cyst can twist on its blood supply (torsion), cutting off circulation to the ovary.
This presents with sudden, extreme pain and is a medical emergency.
A laparoscopy is performed to untwist the ovary and remove the cyst, taking care to preserve normal ovarian tissue.
Occasionally, if the ovary has become necrotic (dead), it must be removed.

Most ovarian cysts are not dangerous, but they should always be assessed properly. With the right diagnosis and management, you can feel confident about your health and treatment options.
