Neurological complications, following lumbar radiculography with Dimer X.

Three cases developing increasing neurological deficit within 24 hours of lumbar radiculography with Dimer X are reported. All three developed severe low back and sciatic pain, and myoclonic spasms within one hour of the examination. In each a large intervertebral disc prolapse was outlined. Two cases developed near complete paraplegia before surgical decompression. Following surgery, two patients made a complete rapid recovery, and the other has recovered partially.
