6 cases of so-called redundant nerve roots of the cauda equina are reported, which brings the total number of cases described in literature to 27. The differential diagnosis of the myelographic picture of tortuous filling defects is discussed. The authors believe that the majority of these cases is caused by chronic compression of the nerve roots.
