Answer

Our ultrasound examination revealed a heterogeneus mass located in the left side of the pelvis and abdomen suggestive of ovarian cyst hemorrhage and torsion. The fetus had no tachycardia and MCA PSV was normal. The baby was born at 38 weeks of pregnancy. The surgery was performed at 5 days and the diagnosis of ovarian cyst torsion was confirmed.
