What is Ovarian Endometrioma? Its Symptoms, Effect, Diagnosis & Treatment

Ovarian endometriomas, commonly known as chocolate cysts, are a specific type of endometriosis where endometrial tissue grows within the ovaries, forming cysts filled with old blood resembling chocolate syrup. Endometriosis is a condition where tissue similar to the lining of the uterus grows outside of the uterus, causing inflammation, scarring, and sometimes severe pain.

There are primarily two types of chocolate cysts:

Endometriotic Cyst: These cysts are filled with thick, old blood, hence the term "chocolate cysts." They develop when endometrial tissue attaches to the ovary and forms a cyst, which gradually fills with menstrual blood.

 

Functional Ovarian Cysts: These cysts are follicular or corpus luteum cysts that form during the menstrual cycle and typically resolve on their own. However, in some cases, endometrial tissue may implant on these cysts, leading to the formation of chocolate cysts.

Symptoms of Chocolate Cysts:

  •  Pelvic Pain: The most common symptom is chronic pelvic pain, often worsening during menstruation.

  •  Dysmenorrhea: Painful menstruation, often accompanied by heavy bleeding.

  •  Pain During Intercourse: Pain or discomfort during sexual intercourse (dyspareunia).

  •  Infertility: Difficulty getting pregnant or recurrent miscarriages.

  •  Urinary and Bowel Symptoms: Some women may experience pain during urination or bowel movements, especially during menstruation.

Effects on Female Fertility:

Chocolate cysts can negatively impact fertility in several ways:

 

  •  Distorted Ovarian Anatomy: The presence of cysts can alter the normal structure of the ovaries, affecting the release of eggs (ovulation).

  •  Adhesion Formation: Endometriosis can cause adhesions (scar tissue) to form around the ovaries and fallopian tubes, hindering the movement of eggs and sperm.

  •  Inflammation and Hormonal Imbalance: Endometriosis and chocolate cysts cause chronic inflammation and hormonal imbalances, which can interfere with ovulation and implantation of a fertilized egg.

Diagnosis of Chocolate Cysts:

  •  Medical History and Symptoms: A doctor will inquire about the patient's medical history and symptoms, particularly focusing on pelvic pain and menstrual irregularities.

  •  Physical Examination: A pelvic examination may reveal an enlarged or tender ovary.

  •  Imaging Studies: Transvaginal ultrasound is the primary imaging modality used to visualize ovarian cysts. Chocolate cysts typically appear as dark, fluid-filled masses on ultrasound.

  •  MRI: Magnetic resonance imaging (MRI) may be used for a more detailed assessment of the cysts and surrounding pelvic structures.

Treatment of Chocolate Cysts:

  •  Pain Management: Nonsteroidal anti-inflammatory drugs (NSAIDs) may help alleviate pelvic pain and discomfort associated with chocolate cysts.

  •  Hormonal Therapy: Birth control pills, progestins, or gonadotropin-releasing hormone (GnRH) agonists may be prescribed to suppress ovulation and reduce the growth of endometrial tissue.

  •  Surgery: If conservative measures fail or if the cysts are large and causing severe symptoms, surgery may be necessary. The two main surgical options are laparoscopic cystectomy (removal of the cyst while preserving the ovary) or oophorectomy (removal of the affected ovary).

  •  Assisted Reproductive Technologies (ART): In cases of infertility associated with chocolate cysts, in vitro fertilization (IVF) may be recommended to bypass fallopian tube obstruction and improve the chances of conception.

 

In conclusion, ovarian endometriomas, or chocolate cysts, are a type of endometriosis characterized by the presence of cysts filled with old blood within the ovaries. They can cause pelvic pain, menstrual irregularities, and infertility. Diagnosis typically involves imaging studies such as ultrasound or MRI, while treatment options range from pain management and hormonal therapy to surgical intervention. Early detection and comprehensive management are crucial in minimizing symptoms and preserving fertility in women with chocolate cysts.
