ABSTRACT Objective: The history of Anatomical Pathology in the state of Paraná, in southern Brazil, is closely linked with the foundation of the Universidade Federal do Paraná (UFPR). This study identified the first central nervous system (CNS) clinical autopsy performed by the Department of Anatomical Pathology of the UFPR. Methods: This study reviewed the autopsy report archives of the Hospital de Clínicas-UFPR from 1951 onward. The clinical anatomy interpretations of the autopsy report and possible etiologic agents were discussed. Result: The first adult clinical autopsy with CNS study was performed on April 23, 1952 on a 45-year-old man with lobar pneumonia with abscesses complicated by bacterial meningitis. Conclusion: This case was the first CNS clinical autopsy performed in the state of Paraná and, possibly, in southern Brazil. The death was due to an infectious disease, which was the main cause of death in Brazil in the 1950s.
