This consists of one to several layers of closelypacked cells distending the Virchow-Robin space, but not encroach-ing on the lumen of the vessel. It is most evident in the branchesof the anterior spinal vessels and is present in both arteries andveins. The cells participating in this process are the same as thosefound in the meninges, namely, large and small lymphocytes pre-dominating, but polyblasts and polymorphonuclear leucocytes aswell as a few plasma cells being present In the cerebral hemi-spheres, as a rule, the vascular changes are not marked and asidefrom the congestion
