Abnormal fetal movements, micrognathia and pulmonary hypoplasia: A case report. Abnormal fetal movements

Abstract

Background: Micrognathia is a facial malformation characterized by mandibular hypoplasia and a small, receding chin that fails to maintain the tongue in a forward position. We previously reported a system of prenatal screening that we developed to identify fetuses with compromised central nervous system function by observing fetal behavior. In this paper we report the case of a preterm infant with micrognathia and pulmonary hypoplasia who presented abnormal fetal movements.Case presentation: A 27-year-old Japanese primigravida at 33 weeks of gestation was referred to our hospital. Ultrasonographic examination revealed clinical polyhydramnios. Micrognathia was evident on midsagittal and 3 D scan. The lung area was less than the mean -2.0 standard deviations for the gestational age. The infant had mandibular hypoplasia and glossoptosis. After emergency cesarean delivery for non-reasuring fetal status, required immediate tracheostomy and cardiopulmonary resuscitation with mechanical ventilatory support. However, the infant's cardiopulmonary condition did not improve and she died 21 hours after birth.Conclusions: The findings of our ultrasound exam are suggestive of brain dysfunction. The observation of fetal behavior appears to be effective for the prediction of prognosis of cases with micrognathia. © 2010 Morokuma et al; licensee BioMed Central Ltd.
