Large Ovarian Dermoid, a Cause for Fetal Growth Restriction and Oligohydramnios: Rare Instance in Literature

Abstract

Ovarian dermoids mostly remain asymptomatic during pregnancy. Large dermoids may present with torsion, hemorrhage, or rupture. However, a dermoid cyst causing fetal growth restriction (FGR) and oligohydramnios is a very rare entity. The authors report a case of a large ovarian dermoid (15 × 12 cm) hampering intrauterine fetal growth. Due to the coronavirus disease-2019 (COVID-19) lockdown, the patient was unable to get ultrasound examinations in early gestation, and thereby, surgical intervention was not possible during the second trimester. As a result, this growing teratoma finally led to FGR by either exerting a pressure effect upon the uterus or by dwindling its blood supply.
