Adult post‐varicella small vessel vaculopathy

In conclusion, in the last few years, antibodies to ion channels and growing number of receptors have been identified in children with acute or subacute onset of CNS syndromes. To our knowledge, this is the first described case of LE associated with anti‐LGI1 in children. An early diagnosis of this rare disease is important because of the potential response to the treatment. In encephalitic processes of unclear etiology, autoimmune mechanisms should be considered when symptoms develop rapidly, accompanied with signs of inflammation in the CSF and/or neuroimaging studies.
