Complex ovarian cysts in infants: A series of nine cases

Female infants frequently develop ovarian cysts (OCs), which vary in onset, development, and prognosis. When the placenta tissue secretes excessive human chorionic gonadotrophin for a variety of reasons, the fetus develops an OC. Because estrogen levels fall after childbirth, the majority of OCs may also naturally involute. Hence, treating infants with OCs may involve close observation. However, even in previously asymptomatic OCs, torsion, intracystic bleeding, or ovarian necrosis could manifest suddenly in the neonatal or infantile period. Here, we report nine such cases of OCs and share our experiences with diagnosis and treatment.
