Inflammation is a vasculitis

• very mild inflammation is a "clean" and very mild, post capilllary, perivenular vasculitis.
• more severe inflammation produces a more severe vasculitis; this may spill over into an arteriolitis, then a frank arteritis (often with thrombosis and haemorrhage), then aneurysm formation and finally, in the severest manifestations, into an aortitis.

So, does the attribution of the label "vasculitic disease" say anything more than that the underlying inflammatory drive is unusually intense? The unpublished "Neurology of Behçet's syndrome" paper explores this escaltion in more detail.
