[Whipple disease of the CNS].

By the example of two cases that could only be cleared up by a postmortem examination the affection of the central nervous system by Whipple's disease is dealt with. The granulomatous inflammatory process which is almost exclusively localised in the grisea and shows a particular concentration in the diencephalon, in the cortex of the frontal, temporal and islet regions as well as in the deeper brain stem, had resulted in a variety of neurological-psychiatric symptoms, in most cases a systemic psychosyndrome, myoclonism and paresis of ocular movement. In both cases the diagnoses was verified by the electromicroscopic identification of the bacteria in the typical SPC cells.
