The clinical and neurological features of four siblings (2 male, 2 female) affected by syringomyelia are described. A fifth sister was affected by an acoustic neurinoma. Since neither parent showed signs of syringomyelia, this is considered to be a datum substantiating the dysembryogenetic theory of the syringomyelia syndrome.
