What Is a Complex Ovarian Cyst?
A complex ovarian cyst is an ovarian cyst or mass that has features other than a simple fluid-filled appearance on imaging. It may contain solid areas, internal divisions, blood, or other material. The term “complex” describes how the cyst looks and does not by itself mean that the cyst is cancerous.
Types of Complex Ovarian Cysts
Several kinds of ovarian cysts can have a complex appearance.
Endometriomas
Endometriomas are associated with endometriosis and develop when endometriosis affects an ovary.
Teratomas
Teratomas, sometimes called dermoid cysts, can contain different kinds of tissue such as skin or hair. Most are benign, although malignant transformation is rare.
Cystadenomas
Cystadenomas develop from cells on the surface of an ovary. They are usually benign but can sometimes grow quite large.
Possible Symptoms
Some complex ovarian cysts cause no symptoms. When symptoms occur, they may include:
- pelvic pain or pressure
- abdominal bloating or fullness
- pain during intercourse
- changes in menstrual symptoms
- sudden severe pain if a cyst ruptures or the ovary twists
How Complex Ovarian Cysts Are Evaluated
Ultrasound is commonly used to examine an ovarian cyst. A healthcare professional may consider the cyst’s:
- size
- shape
- internal appearance
- solid or fluid-filled components
- changes over time
- associated symptoms
Additional testing or repeat imaging may be recommended depending on the findings.
Does a Complex Ovarian Cyst Mean Cancer?
No. Many ovarian cysts and masses are benign. However, determining whether an ovarian mass could be malignant is an important part of medical evaluation, particularly when imaging or other findings are concerning.
Treatment and Monitoring
Treatment depends on factors including symptoms, age, cyst size, imaging appearance, and whether the cyst persists or grows. Some cysts can be monitored with repeat imaging. Surgery may be considered for persistent complex cysts, significant symptoms, or findings that require further evaluation.
When to Seek Urgent Care
Sudden severe pelvic or abdominal pain, especially with vomiting, weakness, dizziness, or other severe symptoms, requires prompt medical evaluation.
