Compartmentalization of the cerebral ventricles as a sequela of neonatal meningitis

Abstract
Thirteen infants with compartmentalization of the lateral ventricles diagnosed by air encephalography, computerized tomography, or autopsy are reported. Of these infants, 9 had meningitis caused by Gram negative bacteria, including Escherichia coli in 6 cases, Klebsiella species in 2, and a Proteus species in 1, and Staphylococcus aureus in 1. In each case, the body of 1 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.
