Adnexal torsion is a rare cause of acute abdominal pain during pregnancy. It is frequently
associated with ovarian stimulation for in vitro fertilization (IVF) or with ovarian masses,
mainly of functional origin. It is uncommon for a normal-sized ovary to undergo torsion. Torsion
of the ovary during pregnancy is common during third trimester. Adnexal torsion is rarely bilateral
and is more common on the right side, perhaps because the sigmoid colon leaves a limited space for
left adnexal mobility. Here we report a case of 23-year-old primigravida with 8 weeks pregnancy
presented with sever left abdominal pain. Left abdominal tenderness was detected. Transabdominal
ultrasound scan reported left adnexal torsion. Laparotomy and then left salpingo-oophorectomy
were performed.
