In cerebral porosis the brain tissues contain a large number of cavities or cysts combined with minute holes generally described as "état criblé." Unlike other types of cavities, such as porencephaly, Marie's1 lacunae, or Grasset's2 progressive lacunar cerebrosclerosis, both cerebral porosis and "état criblé" are so far devoid not only of clinical but also of pathologic significance, being generally considered as artefacts, as accidental postmortem findings, in short, as cadaveric changes. One of these conditions, the "état criblé," has been discussed by me3 at some length elsewhere, while the histologic study of the present case shows that cerebral porosis also possesses certain essential pathologic features which are due to intravitam changes and cannot be looked on as mere artefacts.
