Abstract

Torsion of ovary is an infrequent cause of surgical emergency in pregnancy. Most frequently ovarian torsion occurs in first trimester, occasionally in second and rarely in the third trimester. Diagnosis of ovarian torsion is challenging due to non-specific clinical features. We report here a case of dermoid cyst causing ovarian torsion in second trimester and imaging modalities for its diagnosis and management. A case of 19 year old primi at 24 weeks of gestational age came with complaints of pain in right iliac fossa for 2 days. USG done showed non vascular heterogeneous hyper echoic lesion in right adnexa, suggestive of torsion of right ovary with viable intrauterine fetus. She underwent emergency laparotomy, during which we removed necrotic and gangrenous right ovary and fallopian tube. Ovarian torsion is an infrequent cause of abdominal pain in pregnancy. Though it occurs most frequently in first trimester, it may occur in second trimester also. USG is an accurate tool in diagnosing torsion. Early surgical management is associated with favorable maternal and fetal outcome.
