Guillain-Barré syndrome is a relatively common, acute, and rapidly progressive, inflammatory demyelinating polyneuropathy.

We report a case of systemic lupus erythematosus associated with Guillain-Barré syndrome with marked enhancement of nerve roots of the conus medullaris and cauda equina on MR imaging. These MR observations may help confirm the diagnosis of Guillain-Barré syndrome.
