Diagnosis: Endometriotic cysts
- Endometriotics cysts are noncancerous, fluid-filled cysts that typically form deep within the ovaries.
- It is also known as chocholate cyst due to its appearance of brown, tar-like appearance, looking something like melted chocolate. The colour comes from old menstrual blood and tissue that fills the cavity of the cyst.
- An endometriotic cyst can affect one or both ovaries, and may occur in multiples or singularly.
- It occurs in 20-40% of women having endometriosis.
- Endometriotic cysts can place a a woman of reproductive age at a higher risk for ovarian cancer, can cause pelvic pain, contribute to infertility, decrease ovarian function and interfere with assisted reproductive technologies.
