A patient is diagnosed with monozygotic monoamniotic twins. What is the most accurate explanation for this diagnosis?
Twins that develop from a single fertilized egg, share both placenta and amniotic sac
Monozygotic twins arise from a single fertilised ovum that splits.
If the split occurs between days 8 and 13, the twins share both the placenta and a single amniotic sac — the monozygotic monoamniotic (MoMo) subtype.
Twins from two eggs are dizygotic, and monozygotic twins with separate placentas (dichorionic) share neither sac nor placenta, so those descriptions do not match the diagnosis.
Hence, Twins that develop from a single fertilized egg, share both placenta and amniotic sac.
