It is reported on 3 observations of isolated granulomatous angiitis of the central nervous system. The case in question was in two 42-year-old men a granulomatous giant cell arteriitis with exclusive affection of the intracranial arteries. In a 33-year-old woman (case 3) there existed a granulomatous angiitis in generalised cerebrospinal granulomatous epitheloid-cellular inflammation (sarcoidosis) of the central nervous system with participation of bifurcal lymph nodes and of the lung. In all the three reports the diagnosis could be made only by autopsy. Clinic, pathomorphology, and diagnostic difficulties are described.
