Compartmentalization of the cerebral ventricles as a sequela of neonatal meningitis.

Thirteen infants with compartmentalization of the lateral ventricles diagnosed by air encephalography, computerized tomography, or autopsy are reported. In each case, the body of one or both lateral ventricles was completely divided by a membrane posterior to the foramen of Monro. Recognition of this entity is important from both therapeutic and prognostic standpoints.
