[Subdural empyema due to Salmonella typhimurium. Analysis of a case].

The case was that of an infant with congenital hydrocephalus who developed subdural empyema. The most outstanding items were, the age of the patient (18 months), the identification of Salmonella typhimurium, a germ rarely described responsible for this pathology, the absence of anacrobe germs and the possible hematogenous dissemination from the digestive tract when the port of entry usually associated is the infection of the paranasal sinuses. The most useful method for study was the computerized axial tomography.
