Adnexal Torsion in the Third Trimester of Pregnancy: A Challenging Diagnosis

Abstract

The incidence of adnexal torsion (AT) is reported 1 in 10000 births. AT is emergency condition in pregnancy, while the risk of late diagnosis is increased, in third trimester. Since it has been described as a severe complication after controlled ovarian hyper-stimulation for in vitro fertilization (IVF), it is more common in IVF pregnancies. This condition mainly occurs in the first trimester; it is rare during the late third trimester. Herein, we report a case of a 26-year-old woman, gravida 1, singleton pregnancy in the 30th week of gestation was presented to emergency department with 24-hour history of a stabbing pain because of AT. Removal of adnexa performed by laparotomy. The patient had labour pain and cervical dilatation at the 36th week of gestation and a healthy girl weighing 2,200 g was born by emergency caesarean section due to breech presentation.

Adnexal torsion in the third trimester of pregnancy: a case report and diagnostic value of MR imaging

“…The MR imaging features are not classically described during pregnancy and only reported in a few cases. Compared with several previous case reports [5][6][7], some different MR imaging features of adnexal torsion in late pregnancy are discussed in our study as well as its diagnosis and treatment values.…”

“…2). In several similar reports on the torsion of normal adnexa [5][6][7], the hemorrhagic and necrotic ovaries still appeared hyperintense on T2weighted images. Our finding differed from these reported cases.…”
