The ovaries are two small glands located on either side of the lower pelvis. They play an important role in reproduction, the menstrual cycle, and the development of female sexual characteristics. Each month, a follicle matures into an egg, which is released from the ovary in a process called ovulation. For most women, this happens regularly from puberty until menopause.

Cystic ovarian tumors are quite common in girls and can occur at any age from the fetal period to adolescence. These tumors can be detected incidentally through diagnostic imaging methods or in combination with some symptoms such as abdominal pain, palpable tumors, precocious puberty, and virilization. Although most of these tumors in children are benign or physiological cysts, early diagnosis and close monitoring are necessary to reduce the risk of ovarian torsion that can affect future reproductive function as well as improve prognosis in cases of malignant tumors.

The pouch of Douglas, also known as the pouch of Douglas, is the lowest part of the peritoneal fold between the uterus (anterior) and the rectum (posterior). It is also the lowest part of the peritoneal cavity of the entire abdomen, and is therefore the first place where free fluid accumulates. Therefore, if an ultrasound detects an abnormality, some people will worry about whether the pouch of Douglas fluid will have any effect?

Ovarian torsion is a common disease in women of reproductive age. If not detected promptly, ovarian torsion can lead to necrosis, infection, poisoning and affect future fertility. Therefore, timely diagnosis of ovarian torsion is very important in treating the disease and preventing complications.
