Twin pregnancies discordant for anencephaly-management, pregnancy outcome and review of literature.

Aims And Methods: To examine the prognosis of conservative management in twin pregnancies discordant for anencephaly, we review the literature and report on four of our own cases, which were analyzed retrospectively.

Results: In the University Hospital of Erlangen, six twin pregnancies discrepant for anencephaly were observed during an 8-year period (1992-2000). Four of these pregnancies were managed conservatively.
