Overview
Findings on MRI suggestive of Guillain Barre syndrome include: Anterior and posterior nerve root and cauda equina enhancement.
MRI
- MRI may be helpful in the diagnosis of Guillain Barre syndrome. Findings on MRI suggestive of Guillain Barre syndrome include:[1][2][3]
- Anterior and posterior nerve root enhancement.
- cauda equina enhancement.
NOTE: The underlying etiology of these findings is blood brain barrier disruption due to inflammation.
