Management of ovarian cysts during infancy: autoamputation presenting as a possible pitfall

Summary

The widespread use of routine antenatal ultrasound has relatively increased the frequency of intrauterine diagnosis of ovarian cysts. In utero adnexal torsion may present with subsequent autoamputation in some of these lesions. Prenatal and postnatal ultrasonographic findings, however, may not always be relevant in making the correct diagnosis. The authors report on two cases with prenatally-diagnosed hypoechogenic cystic masses. The cysts failed to resolve after a period of conservative management. A laparoscopic approach revealed ovarian autoamputation presenting as cystic mass. Preoperative ultrasound, abdominal CT and MRI failed to detect the presence of autoamputation. The present report discusses the possibility of an otherwise silent ovarian autoamputation, which may necessitate laparoscopic intervention for correct diagnosis, in neonates presenting with persistent ovarian cysts.
