Le syndrome de Beckwith-Wiedemann : que faut-il rechercher en anténatal ? À propos d’une série de 14 cas

Conclusion Cette étude a permis d’identifier certains signes échographiques anténataux devant alerter le clinicien vers un diagnostic de SBW. Un conseil génétique, après confirmation par biologie moléculaire, pourrait être proposé dans un avenir plus au moins proche en prénatal, et cela afin d’améliorer la prise en charge de ces enfants à risque néonatal. Objectives Beckwith-Wiedemann syndrome (BWS) is the most common overgrowth syndrome and has an incidence of 1/13,700. The majority of the cases are diagnosed after birth. Patients with BWS have an increased risk of neonatal hypoglycemia and embryonal tumors development in childhood. We wanted to identify the ultrasound signs that must alert physicians to prepare best perinatal management strategies. Methods We conducted a retrospective study of a population of 14 cases of BWS diagnosed in perinatal period; four of them were detected prenatally by ultrasound. The anomalies signs described in prenatal were analyzed and compared with the clinical features of the postnatal period. Results The major features reported were represented by macrosomia for 71.4% with an increase of abdominal circumference, and macroglossia for 78.6%. The minor features were various with 64% of visceromegaly (nephromegaly and/or hepatomegaly), 50% of hydramnios and for 80% of male children a genital anomaly (crytorchidism and/or hypospadias). Conclusion This study identified some prenatal ultrasound signs that should alert the...
