Maternal-fetal complications of non-immune fetal hydrops – mirror syndrome and hypereactio luteinalis with ovarian torsion: A case report

Abstract

Mirror syndrome, previously referred to as Ballantyne's syndrome, is a rare obstetric disorder characterized by maternal edema in association with fetal hydrops and placental edema. This report concerns the case of a 35-year-old multiparous woman who developed mirror syndrome secondary to fetal supraventricular tachycardia complicated by hydrops and intrauterine fetal demise. Her pregnancy was further complicated by hypereactio luteinalis with ovarian torsion requiring surgical detorsion. The case highlights the challenges of managing maternal and fetal hydrps, and its rare association with hypereactio luteinalis.
