What Is a Corpus Luteum Cyst?
The normal corpus luteum is a cystic structure that makes the ovary slightly larger. If the cystic corpus luteum persists or grows, or if the corpus luteum hematoma contains more blood, it can cause corpus luteum after the blood is absorbed. Because cysts continue to secrete progestins, the menstrual cycle is often delayed. If the cyst is ruptured, abdominal pain and vaginal bleeding can occur, which is very similar to ectopic pregnancy rupture.

Causes of corpus luteum cysts
- Luteal cysts can develop in three conditions:
- Flavin cyst
- Due to imbalance of pituitary gonadotropin, the corpus luteum is particularly active during pregnancy, and has a larger cavity and more fluid. If the lumen enlarges more than 2 cm in diameter, it is a corpus luteum.
- 2. Leukocyst
- Mostly caused by corpus luteum cysts and cystic corpus luteum evolution. It may also form cysts due to some factors when the normal corpus luteum degenerates into white body.
- 3. Follicular membrane flavin cyst
- Mostly occur in hydatidiform mole, invasive hydatidiform mole, choriocarcinoma. Occurs during normal pregnancy and twins.
Clinical manifestations of corpus luteum
- It can occur in married or unmarried women. It is most common in women of childbearing age, and it is more than that found on ultrasound examination. Rupture of the corpus luteum is usually 20 to 27 days in the menstrual cycle. Sudden abdominal pain, nausea, vomiting, and frequent urination. In severe cases, symptoms of shock such as dry mouth, palpitations, dizziness, fainting, and fainting can occur. Signs of anemia, fast pulse rate, and decreased blood pressure. Lower abdominal tenderness and rebound tenderness were positive for mobile dullness. The cervix lifts pain, the posterior dome is full and tender. Unclear mass on the side of the uterus that can be touched is obvious.
Corpus luteum cyst examination
- Visual inspection
- Most of them are unilateral, the diameter generally does not exceed 4cm, even up to 10cm. It may look like a hematoma at an early stage. After the blood is absorbed, it contains a translucent or brown slurry. The sac wall is light yellow.
- 2. Light microscopy
- In the early stage of cyst formation, luteal cells are still present and rich in lipidoids. Only the inner layer of the cyst wall is fibrotic, and luteinized granulosa cells and follicular membrane cells can be seen, with or without blood in the capsular; Varying degrees of transparency.
Corpus luteum cyst diagnosis
- The B-ultrasound is simple, intuitive, and accurate. It is painless and harmless to the patient, which makes the patient willing to accept it. When ovarian tumors cannot be ruled out, laparoscopy or laparotomy can be performed if necessary to make a clear diagnosis.
Luteal cyst treatment
- 1. Generally there is no special treatment, and the B-ultrasound will be reviewed after menstruation;
- 2. Once cyst rupture, pedicle twist should be treated urgently.
Luteal cyst prevention
- Most of corpus luteum cysts are physiological phenomena, which reduce the burden of thought and physical fatigue, and can reduce the appearance of corpus luteum cysts.
