A 31 year-old G2P1 was referred to our department at 37 weeks of her pregnancy due to cystic abdominal mass. Her previous ultrasound examinations at 12 , 20 and 30 weeks were reported to be normal and the course of the pregnancy was uneventful. 


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 day 5 and the diagnosis ovarian cyst torsion was confirmed.

Image 3 showing multifollicular enlargement caused by transudation of fluid into the follicles secondary to congestion in torsion. Small amount of free fluid is noted adjacent to the cyst suggesting the peritoneal irritation.
