Cerebral amyloid angiopathy
Cerebral amyloid angiopathy (CAA), also known as congophilic angiopathy,[1] is a form of angiopathy in which amyloid comes out of the walls of the blood vessels of the central nervous system.[2]
The term congophilic is used because the amyloid appears red when looked under a microscope when Congo red dye is used. The amyloid material is only found in the brain and as such the disease is not related to other forms of amyloidosis.[3]
