Résumé
Hydrops fetalis is diagnosed when abnormal fluid collections are manifest in two or more fetal compartmnets including abdominal ascite, pleural effusion, percardial effusion, skin edema, polyhydroamniosis and placental edema. Although fetal hydrops was historically most commonly associated with Rh blood group isoimmunization, the availability of Rh immunoglobulin has increased the proportion of fetuses affected due to nonimmune etiologies. Neuroblastoma is a malignant tumor which originates in the autonomous nervous system. Congenital neuroblastoma is the most common solid malignant tumor of the neonatal period, incidence ranges 1:10,000 of all live births, retroperitoneal space being the most frequent localization. We have experienced a case of nonimmune hydrops fetalis with neuroblastoma at 32 weeks of gestation in 39 year old woman and reported that with brief review of related literatures.
