Diffusion Imaging in Acute Auto-immune Encephalitis
Diffusion Imaging in Acute Auto-immune Encephalitis
The aim of this non randomised retrospective study is to investigate the imaging (MRI) of
 auto-immune encephalitis at presentation, especially in diffusion-weighted sequences.

 Indeed, few series describe the MRI aspect of auto-immune at their beginning. Recognize early
 MRI abnormalities seen in auto-immune encephalitis could help reduce the time to positive
 diagnosis and improve the therapeutic management.
Inclusion Criteria:

 -  Auto-immune encephalitis proved by biological results (blood and/or CSF sample)

 Exclusion Criteria:

 -  No MRI available
