Atypical case of mild encephalopathy/encephalitis with reversible splenial lesion of the corpus callosum (MERS) associated with Mycoplasma pneumoniae infection in a paediatric patient.

Mild encephalopathy with reversible splenial lesion (MERS) is a disorder characterised by prodromal symptoms such as fever, cough, vomiting or diarrhoea, followed by mild encephalopathy 1-7 days later with a documented reversible corpus callosum splenial lesion. MERS is mostly reported in children in the region of East Asia. To the best of our knowledge, this is the first reported case of MERS associated with mycoplasma infection in a child in North America. A brief review of literature is also a part of this report.
