There is subependymal periventricular hyperintensity along the lateral and third ventricles in the T2 (not shown) and FLAIR sequences. The ventricular walls show diffusion restriction. The choroid plexus and ventricular walls show contrast enhancement. There is no basal meningeal contrast enhancement. The rest of the brain MRI is normal.
The MRI features are consistent with ventriculitis.
