[Pena-Shokeir syndrome type I--combination of polyhydramnios and pulmonary hypoplasia in fetal akinesia].Orv Hetil. 2010 Jun 13; 151(24):990-3.OH
We present the case of an 18-year-old woman with her second pregnancy, whose first pregnancy was complicated by polyhydramnios. At week 30, the dysmorph fetus died in utero and was delivered via cesarean section due to placental abruption, but the exact diagnosis was not recognized at that time. During the patient's second pregnancy, increasing polyhydramnios was detected from the 19th gestational week. Ultrasound signs of fetal malformation also appeared later: abnormal position of limbs, narrow chest, oedema around the skull, and absence of stomach content. At week 34, decompression amniocentesis became necessary. Chromosome analysis was also carried out and a normal karyotype was obtained. At 39th gestational week, amnioscopy proved meconium staining of the amniotic fluid, thus labour was induced. Following amniotomy, sustained fetal bradycardia commenced and an emergency caesarean section was performed. Despite complex resuscitation, the 3000 gram male newborn died 2.5 hours after delivery, due to respiratory failure. Autopsy and histopathologic examination revealed a large, oedematous head, micrognathia, macroglossia, laryngeal oedema, narrow chest with pulmonary hypoplasia, gracile limbs with muscle atrophy, gracile and bent fingers, and a short umbilical cord. Based on the medical history, the course of the disease and the phenotype of the newborn, Pena-Shokeir syndrome type I was diagnosed. In the second part of the article, we review the etiology, pathogenesis, prenatal diagnosis and differential diagnosis of this syndrome, as well as some aspects of genetic counseling in such cases. To our knowledge, this is the first reported case of Pena-Shokeir syndrome in Hungary.
