Summary
Prenatal ultrasound detects fetal ovarian masses. Simple cysts under 5 cm often resolve spontaneously postnatally due to hormonal shifts, while larger or complex cysts may require intervention to prevent complications like ovarian torsion.
Area of Science:
- Pediatric Surgery
- Fetal Medicine
- Neonatal Care
Background:
- Prenatal sonography increasingly identifies fetal ovarian masses.
- Understanding the natural history of these asymptomatic lesions is crucial for postnatal management.
Purpose of the Study:
- To outline the natural history and management strategies for fetal ovarian masses detected prenatally.
- To guide clinical decision-making regarding intervention versus observation.
Main Methods:
- Review of the expected hormonal changes postnatally influencing ovarian cyst resolution.
- Sonographic assessment criteria for simple versus complex ovarian cysts.
- Discussion of surgical and non-surgical intervention options.
Main Results:
- Simple ovarian cysts <5 cm are expected to resolve spontaneously by 6 months postnatally.
- Larger simple cysts (>5 cm) carry a higher risk of torsion, often warranting intervention.
- Complex cysts frequently indicate adnexal torsion or neoplasm, necessitating prompt intervention.
Conclusions:
- Management of fetal ovarian masses requires balancing the risk of torsion against the likelihood of spontaneous resolution.
- Maximizing ovarian salvage is the primary therapeutic goal.
- Laparoscopic approaches offer versatile options for diagnosis and treatment of neonatal ovarian cysts.
