Flashcard 109: If the developing embryo splits during **days 8-12** (bilaminar disc stage), the twins will be _____-chorionic and _____-amniotic
Answer: mono
Extra: The timing of monozygotic twinning determines chorionicity and amnioticity:
- **Days 0–4** (cleavage/morula): Dichorionic, Diamniotic (2C/2A)
- **Days 4–8** (blastocyst stage): Monochorionic, Diamniotic (1C/2A)
- **Days 8–12** (bilaminar disc stage): Monochorionic, Monoamniotic (1C/1A)
- **>13 Days** (primitive streak): Conjoined twins

Dandy-Walker syndrome
Cranial MRI of a young child (T2 weighted, sagittal view)
The region of the posterior fossa and the pons appear cystic and hyperintense.
The cerebellum also appears hypoplastic and the posterior fossa is enlarged.
This radiographic appearance is suggestive of Dandy-Walker syndrome.
