Abnormalities of the Posterior Cerebral Fossa

  • Guibaud Laurent


The abnormalities of the posterior fossa (PF) observed in antenatal examinations include the small posterior fossa associated with a defect of neural tube closure in Chiari II malformation (see Chap. 11), the congenital cystic abnormalities of the PF, and a heterogeneous group of exceptional abnormalities such as rhombencephalosynapsis, tumoral lesions and vascular malformations.
