title: [Syringomyelia: four clinical cases are reported as opportunity to reexamine the pathogenetic hypotheses (author's transl)].
abstract: In this paper four clinical cases of syringomyelia are presented as an opportunity to reexamine more discussed pathogenetic hypotheses. The authors are referring in particular to Gardner's theory since he has the merit of explaining the anomalies often associated with syringomyelia. In Gardner's opinion syringomyelia might be due to the non-perforation of the rhombic roof.
