Types of Cysts

Functional - normal and not likely to cause problems
Ovarian Cysts - pathological
Adnexal Masses - cysts related to but not arising from ovary


Normal and not likely to cause problems.

Follicular Cysts - Ultrasound picture of a typical follicular cyst.

Laparoscopic view of a simple follicle or follicular cyst.
Corpus Luteum Cysts - Ultrasound picture of a corpus luteum or cystic corpus luteum.
Ovarian Cysts


Endometriotic Cyst - Typical ultrasound picture. Various technical terms such as homogeneous, uniformly echogenic cystic area are often used. In layman terms the "ground glass effect" is aptly descriptive of ultrasound appearance of endometriotic cysts.

Laparoscopic view of small endometrioma. The endometriotic cyst is being drained, the chocolate material released is the reason these cysts are commonly called "chocolate cysts".
Laparoscopic view of large endometriomas. Endometriosis often affect both ovaries and the cysts are adherent (joined) behind the uterus. These are called "kissing ovaries". This picture is surprisingly free of adhesions which accompany kissing ovaries.
Laparoscopic view of large endometriomas and adhesions. This is more typical of kissing ovaries where adhesions cause attachment of bowel to the ovaries.
Dermoid Cyst - Typical ultrasound picture of dermoid cyst.
Laparoscopic view of dermoid cyst. Dermoid cysts are usually mobile and free of adhesions. This patient also has a small fibroid on the left near the cornua of the tube.

Serous or Mucinous Cystadenomas

Carcinoma of Ovary

Adnexal Masses

Cysts related to but not arising from ovary

Fimbrial Cysts
Small fimbrial cysts are very commonly found and do not require removal.

When fimbrial cysts grow unusually large they may cause pain if they get twisted and lose their blood supply.
Another example of a twisted cyst.
When fallopian tubes get blocked and swollen they may look like cysts on ultrasound examination.
