Abstract

Here we report two infants with bacterial meningitis associated with restricted water diffusion in the corpus callosum. Both patients were admitted because of pyrexia and not doing well. One patient had a seizure. Group B streptococcus was isolated form blood and cerebrospinal fluid of both patients. Diffusion-weighted images showed transiently restricted water diffusion in the corpus callosum in both patients without additional neuroimaging abnormalities. The outcome of the patients is presumed to be favorable. The magnetic resonance imaging findings of our patients will widen the spectrum of restricted water diffusion in the corpus callosum.
