Histopathological Findings in General Paresis after Penicillin Treatment: Report on 4 Cases

Abstract
There have been several deaths during or after penicillin therapy for G.P.I. (Goldman, 1945; Neymann et al., 1945; Weickhardt, 1946, and Rose and Solomon, 1947), but there have been no reports of neuropathological studies. We think, therefore, that it may be of some value to describe the pathological findings in the brains of four such cases.
