title: Prenatal ultrasound diagnosis of frontonasal dysplasia.
abstract: We report a case of prenatal ultrasound diagnosis of frontonasal dysplasia. This represents a very rare disorder involving the face (hypertelorism, median cleft lip, absence of the nasal tip) and often the central nervous system (CNS) (cranium bifidum occultum, ethmoidal cephalocele, agenesis of the corpus callosum). Although several of the typical anomalies are diagnosable by ultrasound in utero (hypertelorism, median cleft lip, anterior cephalocele), very few cases have been reported prenatally, the present being only the third. In the present case, hemimegalencephaly is first reported among the anomalies possibly associated with frontonasal dysplasia. The diagnosis was made at 22 weeks' gestation and was confirmed by necropsy following termination of pregnancy.
