[Mirror syndrome: literature review based on a case]

Mirror syndrome or Ballantyne syndrome is a rare disease, characterized by the association between fetal anasarca and maternal generalized edema. This may be complicated by pre-eclampsia. The purpose of this study was to highlight the diagnostic and therapeutic features of this severe clinical entity, which, despite its rarity, should be suspected. We here report the clinical case of a 35-year-old parturient woman at 26 weeks of amenorrhea presenting to the Emergency Department with idiopathic mirror syndrome whose progression was rapidly marked by the occurrence of intrauterine fetal death and remission of maternal clinical-biological symptoms, once uterine vacuity was obtained. Indeed, a specific treatment in uterus is necessary, although in some severe idiopathic cases, only uterine vacuity can improve maternal and fetal prognosis.
