Pseudolesion with nonionic contrast myelography.
Water soluble contrast myelography has been associated with a variety of complications. The inadvertant injection of air into the thecal sac may produce an apparent extramedullary, intradural defect on myelography. Post myelography CT examination should be used to confirm the presence of such a pseudolesion.
