An ovarian cyst is a fluid-filled sac in or on an ovary, and many are harmless or temporary.
Many ovarian cysts cause no symptoms, but some lead to pelvic pain, bloating, pain during sex, period changes, or a feeling of pressure.
Imaging helps when pelvic pain, a possible adnexal mass, or abnormal bleeding needs assessment, and it helps show whether the cyst looks simple, complex, or suspicious.
Ultrasound is usually the first imaging test because it helps show whether the cyst looks simple, complex, or suspicious.
Some cysts only need observation, while others need follow-up, gynecology review, or surgery depending on symptoms and appearance.
This entry explains the finding. The next step is having a radiologist interpret your specific scan, not a general definition.
