Can identical twins have different sacs and placentas?

Twins that develop in separate sacs surrounded by two separate chorions are considered dichorionic. All dizygotic, or fraternal, twins are dichorionic. 1 Some monozygotic (identical) twins may also be dichorionic. Dichorionic twins have two individual placentas, although sometimes the placentas can fuse together.

The twin that stops growing will be reabsorbed into your placenta and into the baby that you’re carrying. Small indicators of the twin might remain in your placenta when you deliver your baby. In most cases, your pregnancy will continue as it would have if you were carrying one baby to begin with.
