Pathologic and virologic findings for 2 patients with tick-borne encephalitis, Finland, 2015. A) Magnetic resonance images of 36-year-old woman (patient 1) with pathologically increased signal in cortical sulcus regions indicative of viral meningeal process (arrow). B) Hematoxylin and eosin staining of the frontal cortex of patient 1 showed inflammation throughout the central nervous system from the spinal cord to the cortex and cerebellum; original magnification ×100.
