Initial MR imaging of the patient. Magnetic Resonance Imaging of the brain in the acute phase of neurological involvement. Diffusion Weighted MR Imaging of the brain performed in the acute phase of encephalitis (A). Axial T2 FRFSE image shows hyperintensity of white matter with involvement of internal and external capsule (B). Axial T2 FLAIR image demonstrates hyperintensity of white matter; involvement of the ventricular system with reduction in the size of the fourth ventricle is also shown (C). On the T1W Axial FLAIR there is enhancement of cerebral vessels after contrast agent was administered. Hyperintensity of cerebral vessel (D).
