Introduction Uterine torsion has been defined as a rotation of more than 45 degrees of the uterus around its long axis that occurs at the junction between the cervix and the corpus. The extent of the rotation is usually 180 degrees, although cases with torsion from 60 to 720 degrees have been reported. Aetiopathogenesis of this condition is still unclear. Establishing clinical diagnosis of this condition is difficult, but very important for reducing maternal and fetal morbidity and mortality. Clinical symptoms are either absent or nonspecific, and the diagnosis is usually made at laparotomy. Case outlineA 31-year old patient was admitted to the Institute of Gynecology and Obstetrics, Clinical Center of Serbia, Belgrade, as an emergency, seven days upon the established intrauterine fetal demise in the 40th gestation week. On uterine examination, the cervical length of 1.5 cm and dilatation of 3 cm were determined, as well as a palpable soft tissue formation, not resembling placenta praevia. Ultrasound examination confirmed fetal demise and exclusion of the presence of placenta praevia. The labor was completed by caesarean section. During surgery, uterine torsion of 180 degrees to the right was diagnosed. There was a stillborn male baby, and the cause of death was intrauterine asphyxia. A fibrosing and calcified accessory lobe 9x6x2.5 cm in size was observed on placental examination, which is a possible sign of initial gemellary pregnancy. Conclusion The clinical presentation of uterine torsion is variable and clinical examination and ultrasonographic scanning may be insufficient for diagnosis. The method of choice for establishing the diagnosis is magnetic resonance imaging. Once the diagnosis of uterine torsion in pregnancy is established, emergency laparotomy is indicated. Following caesarean delivery, it is necessary to surgically remove all the anatomical causes of torsion, and rotate the uterus back to its normal position. There are some authors who suggest bilateral plication of the round ligaments as a preventive procedure for repeated torsion in puerperium and following pregnancies. The effectiveness of this method requires further investigation. It is necessary to have in mind the possibility of uterine torsion in all cases of abdominal pain during pregnancy and dystocia.
