Meningitis with subdural empyema due to non-typhoid Salmonella in a 9-month-old girl.
We report a case of a 9-month-old baby admitted to the hospital because of low-grade fever, focal seizures in a context of watery diarrhea for 14 days' duration. The patient workup revealed a mild neutrophilic pleocytosis on cerebrospinal fluid (46 cells/microl), a positive stool culture for Salmonella pomona sensitive to ceftriaxone and ciprofloxacin, and a subdural empyema (SDE) on the cerebral MRI. The child received an intravenous third-generation cephalosporin for 4 weeks which resulted in cure. This case highlights an unusual extra-intestinal complication of non-typhoid salmonella infection. Involvement of the central nervous system with non-typhoidal salmonellosis is an important complication that can result in significant morbidity if not recognized and treated promptly. A focal intra-cranial infection must be considered in the differential diagnosis of any child presenting with focal seizures and gastroenteritis due to Salmonella. Appropriate diagnostic imaging of the head (cerebral CT scan with contrast and/or MRI) is mandatory to exclude the presence of an intra-cranial complication, even in the presence of negative CSF culture for Salmonella. Subfrontal and subtemporal SDE are sometimes missed on axial CT scans and better appreciated on MRI. Non-surgical treatment of small subdural empyemas with prolonged intravenous antibiotic therapy is a therapeutic option.
