Abstract:

Pedicle torsion is a common complications of ovarian tumors. There is an increased risk of torsion during pregnancy, usually in early or mid-pregnancy. Delayed treatment may lead to tumour necrosis, rupture, and secondary infection, or even loss of maternal ovarian function and fetal death. The diagnosis of torsion is difficult. As a cause of acute abdomen, its clinical manifestations are usually non-specific, the differential diagnosis range is wide-ranging, and it is prone to misdiagnose. Ultrasound is usually considered the first-line imaging method for evaluating acute abdomen in pregnant women, and surgery is the standard treatment for pedicular torsion. We report the case of torsion of the pedicle with serous cystadenoma of the ovary in the third trimester of pregnancy. The patient was treated for abdominal pain and underwent emergency surgery after diagnosis of torsion of the pedicle by ultrasonography. After 58 days of operation, a healthy baby girl was delivered spontaneously. Through this case we reviewed relevant literature and summarizing clinical experience, in order to deepen our understanding of this disease, improve diagnosis and treatment ability, and reduce misdiagnosis and missed diagnosis.
