Torsion of the ovary is the partial or total rotation of the ovary over its pedicle. It is unusual for it to occur in the second trimester. We report a case of a 35year old G10P9+0A7 at 17weeks gestation who presented with acute severe abdominal pain. She was found to have an ovarian cyst in pregnancy. She had Exploratory Laparotomy where a huge gangrenous cyst was found and Salpingoophorectomy was performed. The pregnancy continued without any problems. The histology report showed a Simple Cyst.
