# A case of giant ovarian cyst during pregnancy

## TL;DR

This paper presents a case of a large ovarian cyst during pregnancy that required surgical intervention due to complications.

## Contribution

The paper contributes a clinical case highlighting the management of a giant ovarian cyst during pregnancy.

## Key findings

- Ovarian cysts during pregnancy can grow significantly and cause complications like previa obstruction.
- Surgical cystectomy can be safely performed alongside a caesarean section when necessary.
- Ultrasound is essential for monitoring ovarian cysts during pregnancy.

## Abstract

The incidence of ovarian cysts in pregnancy has risen considerably since ultrasound was first routinely performed in pregnant women. This incidence is between 0.3% and 5.4%. The main risk of complication of ovarian cysts during pregnancy is adnexal torsion, estimated at around 8%. Ultrasound remains the gold standard for identifying ovarian tumors during pregnancy. A part from complications, expectant management is recommended during pregnancy in view of the maternal-fetal risk of surgery. When surgery is indicated, laparoscopy is the preferred approach during the 1st and 2nd trimesters. The ovarian tumor should not affect the delivery procedure, except in the case of a complication of suspected malignancy or a previa obstruction, as in the case of our patient. We present a 30-year-old patient with no pathological medical history who underwent surgery for a benign ovarian cyst 10 years ago, G3P3, unscarred uterus, who consulted us at 38 SA for pregnancy monitoring. In addition, there was only one prenatal consultation during the follow-up, with an ovarian cyst measuring 5 cm at the first trimester ultrasound. During the obstetric ultrasound, we noted the presence of a 13 cm unilocular anechogenic cystic image with a regular wall, creating a Previa obstruction. A prophylactic caesarean section was performed with simultaneous cystectomy without incident.
