Dichorionic, diamnionic twin pregnancy discordant for anencephaly: Report of two cases and literature review

Abstract

Anencephaly is a lethal diagnosis. In the unique situation of a twin pregnancy discordant for anencephaly, early ultrasound diagnosis based on the discrepancy in the appearance of the heads can facilitate management and potentially decrease morbidity and mortality for the unaffected twin. We report two such cases of dichorionic, diamniotic twin pregnancies and provide a review of the literature.

“…Anencephaly is untreatable congenital anomaly that occurs more frequently in twin pregnancies than in singletons [5]. Its diagnosis can be reliably made with ultrasound as early as 11 weeks of pregnancy [9]. In our case, the diagnosis was made in early 3 rd trimester pregnancy during her initial visit to private clinic.…”
