INTRODUCTION Torsion of ovary is total or partial rotation around its vascular axis or pedicle. Torsion in pregnancy is relatively rare and requires specific management for optimizing feto-maternal outcome. AIMS AND OBJECTIVES Pregnancy is a high-risk factor for ovarian torsion with chances of necrosis and sepsis. The objective is to describe a case of ovarian torsion in pregnancy, its management and outcome followed by a discussion on similar torsion cases in pregnancy. MATERIAL AND METHODS A 25-year-old G4P1L1A2 (previous 1 LSCS) presented with 3 months amenorrhea and severe pain abdomen and vomiting. Her USG was suggestive of cyst of 9.2*5.7 cms with right ovarian torsion. Emergency laparotomy was done with right salpingo oophorectomy in view of completely necrosed and edematous ovary and fallopian tube. Left ovary was healthy. Specimen was sent to histopathological examination. She was given progesterone support up to 20 weeks and her pregnancy was followed up till delivery. RESULT Histopathological examination showed hemorrhagic ovarian cyst along with a benign mucinous cystadenoma. Patients pain subsided immediately in the postoperative period and recovery was uneventful. She was followed up in Antenatal OPD and given progesterone support (Injectable and oral) up to 20 weeks. Her pregnancy continued unremarkably and she delivered a live 3.34 kg baby at term gestation by caesarean section. CONCLUSION Torsion in pregnancy is an emergency situation presenting with severe pain and can lead to increased feto maternal morbidity and mortality. It sometimes requires operative management with removal of the affected ovary and fallopian tube. Progesterone support needs to be given for continuing the pregnancy based on the gestational age at diagnosis. Appropriate management leads to a good feto-maternal outcome.
