What are the symptoms of ovarian cyst torsion?

Generally speaking, patients with ovarian cysts are also likely to develop ovarian cyst pedicle torsion. The symptoms of ovarian cyst pedicle torsion are relatively obvious, accompanied by nausea and vomiting, and in more serious cases, seizures may occur.

Pedicled torsion is a common gynecological acute abdomen. About 10% of ovarian tumors are complicated by pedicle torsion. It is more common in tumors with long pedicles, medium size, good mobility, and center of gravity biased to one side (such as teratomas). Pedicle torsion often occurs when the patient suddenly changes body position, or when the size or position of the uterus changes during pregnancy or the postpartum period. The pedicle of ovarian tumor torsion is composed of the pelvic infundibulocele ligament, the ovarian proper ligament and the fallopian tube. After acute torsion, venous return is blocked, the tumor becomes extremely congested or blood vessels rupture and cause bleeding inside the tumor, causing the tumor to rapidly enlarge. Later, due to obstruction of arterial blood flow, the tumor undergoes necrosis and turns purple-black, which may rupture and cause secondary infection. Sometimes incomplete torsion can be naturally reduced, and the abdominal pain will be relieved. Once pedicle torsion is confirmed, laparotomy should be performed as soon as possible.

The most common cause is ovarian cystic lesions, such as ovarian epithelial cysts, dermoid cysts, ovarian crown cysts, etc. The increase in ovarian volume and weight caused by the above reasons may be an important cause of ovarian torsion. It can occur in one or both ovaries, but bilateral torsion is less common.

Clinical manifestations

1 Symptoms

Patients with a history of pelvic or adnexal masses suddenly experience severe pain on one side of the lower abdomen, often accompanied by nausea, vomiting, and even shock. Abdominal pain can be relieved when the torsion pedicle is naturally reduced or the tumor is completely necrotic.

2 Signs

Pelvic examination revealed cervical lifting and swinging tenderness, the uterus was normal size, and a mass was palpated in the adnexal area on one side with high tension and tenderness, most obvious at the pedicle.
