Multiple brain abscesses in neonate caused by Edwardsiella tarda: case report.

A neonate presented with multiple brain abscesses caused by very unusual infection with the Gram-negative bacterium, Edwardsiella tarda. Serial changes in magnetic resonance imaging findings including diffusion-weighted imaging demonstrated the development from the late cerebritis to late capsule stages. The patient was successfully treated by external drainage, and has since reached normal development milestones. Early diagnosis with computed tomography, magnetic resonance imaging, and ultrasound tomography, and prompt external drainage were essential to the good outcome of this case.
