Steroid-Responsive Meningitis-Arteritis in Dogs

Meninges are the membrane layers that cover and protect the outer surface of the brain and spinal cord. Meningitis refers to inflammation of the meninges.

Steroid-responsive meningitis-arteritis describes the combined conditions of inflammation of the protective membranes covering the spinal cord and brain (meninges), and inflammation of the walls of the arteries.
