Patient's question:
Seven days before menstruation, a luteal cyst was found in the ovary. After completing menstruation (normal amount, usually lasting 5-7 days), I went for a follow-up ultrasound on the fifth day and discovered that the cyst had disappeared. How can it be proven that there was an ovary follicle, but it did not rupture, and there is no menopause, yet it formed a luteal cyst. For the past two days, I have been using menopause test strips to check for menopause, but they have always shown a weak positive result, indicating the presence of a luteal cyst. Previously, after a follow-up ultrasound on the fifth day of menstruation, no cyst was found.What kind of help is needed: Is a luteal cyst a condition before or after menopause?
Doctor's answer:
Corpus luteum cysts can be formed by the following three conditions: (1) Lutein cyst: The corpus luteum forms due to endocrine imbalance caused by pituitary gonadotropin, especially in early pregnancy where the corpus luteum function is highly active, the cavity is large, and it contains a significant amount of fluid. If the cavity size decreases and the diameter is less than 2 centimeters, it is considered a corpus luteum cyst. (2) White body cyst: It is mostly derived from corpus luteum cysts and cystic corpus luteum. It may also form during the normal atrophy of the corpus luteum into a white body due to certain factors. (3) Follicular theca lutein cyst: It often occurs again in cases of molar pregnancy, invasive mole, and choriocarcinoma. Approximately 50-60% of molar pregnancies are accompanied by follicular theca lutein cysts, though the actual incidence may be lower. It occasionally occurs in normal early pregnancy and twin pregnancies.
