Intracranial giant cell arteritis.

A case of giant cell arteritis of intracranial vessels diagnosed by autopsy is described. Giant cell arteritis of the proximal basal brain arteries was exceptionally marked in a man of 60 years. The clinical course, laboratory findings and the pathological alterations of the brain and intracranial blood vessels are described. The case is discussed on the basis of the literature on giant cell arteritis with cerebral symptoms as well as on granulomatous giant cells arteritis of the brain. A separation of these two entities does not seem justified.
