The unique microenvironment within the central nervous system (CNS) relies upon the integrity of the blood-brain barrier (BBB). This selectively permeable barrier comprises interendothelial tight junctions located at the capillaries and postcapillary venules. Cells and structures in the local environment are required to maintain normal BBB function. When inflammation is present, the BBB itself plays an integral role in the inflammatory response by either producing or expressing a variety of cytokines, adhesion molecules, metalloproteinases, serine proteases, products of arachidonic acid metabolism, and nitric oxide. Understanding the role of the BBB during inflammation is essential when creating and employing a therapeutic regime for animals with CNS disease. This review focusses on recent discoveries about the BBB and its role in inflammation, and applies this knowledge to our current understanding of inflammatory CNS disease in dogs and cats.

“…Traffic accidents are common causes of cerebral contusion in dogs (Kolata and Johnston, 1975), but reports in feline cases are rare. Yamada et al (1998) described the detection of a contrecoup lesion in a cat's brain with the aid of MRI recently. In the present report, the injured cerebrum of a cat after a probable traffic accident was examined macroscopically, histologically and by a post-mortem MRI to define the correlations between pathological changes and MRI signals.…”

Necropsy was performed on a mongrel male cat of unknown age weighing 1.3 kg, which probably encountered a traffic accident. Gross pathological examination of the brain revealed reddish colour of the right cerebral hemisphere and haemorrhages on the surface of the right frontal lobe to temporal lobe. Histologically, there was diffuse vacuolation in the cortex of the right frontal lobe and extensive haemorrhages in the base of brain. These histopathological findings were consistent with areas of abnormal signals found on post-mortem magnetic resonance imaging (MRI). In this study, the MRI findings were identical to that reported in human cases of head trauma as well as histopathological changes.
