[Giant cell granulomatous angiitis of the central nervous system].

The case is described of a coloured woman of 58, previously affected by filaria, who presented with meningo-encephalitis which proved fatal within a month. Pathological anatomy showed granylomatous angiitis with giant cells scattered throughout the brain and the meninges but confined exclusively to the nervous system. Biological and anatomopathological tests were unable to connect this condition with any precise aetiology. The aetiology of granulomatous angiitis is discussed in this connection and the clinical and anatomopathological charateristics peculiar to giant cell granulomatous angiitis of the nervous system are recalled.
