Symptomatic Persistent Fetal Ovarian Cysts

Vomiting in young infants is a common presentation to the pediatric emergency department with a broad differential diagnosis. We present 2 cases seen in our emergency department of infant females with symptomatic complex ovarian cysts who presented with vomiting. The first case study describes a patient with a prenatally diagnosed ovarian cyst that was being followed with serial ultrasounds by general surgery. The second case study describes a patient with reportedly normal prenatal ultrasounds with a subsequent diagnosis of a large complex ovarian cyst. These cases were selected to review pertinent imaging findings, discuss management decisions, and expand the differential of vomiting in the young female infants.
