Pneumocephalus in neonatal meningitis.

Pneumocephalus is collection of gas or air within the cranial cavity. This has been described with trauma, cranial surgery, air embolism, and rarely as a result of central nervous system infections. We report a case of diffuse pneumocephalus secondary to Enterobacter cloacae meningitis. The diagnosis was suspected by cranial ultrasound and confirmed by computer tomography.
