Das Kaudakompressionssyndrom bei myelographisch totalem Kontrastmittelstop durch Massenprolapse und andere spinale Raumforderungen

Abstract

Twenty-seven cases of complete subarachnoid block discovered through myelography are analysed with regard to the causes of obstruction, the neurologic symptoms, and the cerebrospinal fluid. The neurologic signs in cases of cauda equina compression, most often caused by massive disc protrusions (20 patients), vary considerably and rarely correspond to the gross myelographic findings. Bilateral neurologic symptoms of any degree with or without sphincter disturbance were observed in 21 among 27 cases and are signs of cauda compression. In contrast to cases of sciatica with unilateral root compression and radicular symptoms neurological symptoms are not reliable in revealing the site of the lesion in cases of massive central disc protrusions. Therefore radiculography (myelography of the cauda equina) is necessary for diagnosis. In addition to the well-known elevation of the spinal fluid protein and pleocytosis, the presence of neutrophile granulocytes is frequently found (11 of 20 cases) in cytological analysis.
