The authors studied 146 choroid plexus of patients that were autopsied at the Department of Pathology of FFFCMPA in the period of January 1983 to October 1984. They analysed the histopathological details at different ages and disclosed vacuolisation and presence of eosinophilic material in the intersti-tium of choroid plexus in the first years of life and calcification and cystic formation at the glomus of choroid plexus that were more accentuated in the older patients.
