Myelography in Guillain-Barré syndrome (acute inflammatory polyradiculoneuropathy).

The Guillain-Barré syndrome has been studied by lumbar myelography with watersoluble contrast media in seven cases. Abnormalities, which consisted of widening of the nerve roots and obliteration of the root sleeves, were found in three of them. It is possible that myelography accentuated the symptoms in one case while the rest tolerated the examination well.
