An Ovarian Dermoid Cyst in Pregnancy: A Rare Cause of Intrauterine Growth Restriction

The most common ovarian tumour presenting during pregnancy are dermoid cysts, usually present in the second trimester. Mostly dermoid cysts are diagnosed during ultrasound in antenatal period. We report a case of large unilateral dermoid cyst which was missed in all USG done in antenatal period but diagnosed intra-operatively while performing caesarean section for Intra uterine growth restriction (IUGR) with fetal distress. Ovarian cystectomy was done and remaining ovarian tissues were preserved. The large dermoid cyst hampered the proper growth of the fetus in utero leading to IUGR and fetal distress. Ovarian dermoid cyst in antenatal period, a rare cause of IUGR and its successful management prompted us to report this case.
