Uterine torsion and subsequent rupture in a gravid bicornuate uterus associated with an elevated alpha-fetoprotein.

Uterine torsion is a rare obstetric complication with a non-specific presentation. We describe a patient with a bicornuate uterus and a pregnancy complicated by a markedly elevated second-trimester maternal serum alpha-fetoprotein (MSAFP), intermittent pelvic pain and fetal growth restriction. At 24 weeks gestational age, she presented to labour and delivery with an acute abdomen.
