Dear Editors,

Le Bras and colleagues [1] recently reported an interesting case series describing seven children with reversible splenial lesion of the corpus callosum. Reversible splenial lesion syndrome is a recently introduced nosologic entity with a variety of clinical manifestations and of different aetiologies [2]. Possible causes include seizures, antiepileptic drugs withdrawal, infections, altered metabolic states such as hypoglycemia and hypernatremia and other associated clinical conditions such as X-linked Charcot-Marie-Tooth disease [1, 2, 3]. Clinical symptoms vary from altered consciousness (confusion, lethargy, delirium) to seizures or focal neurologic symptoms that are usually unrelated to the splenial lesion. MRI findings also vary from a single ovoid lesion centred in the splenium of corpus callosum with diffusion restriction (also referred to as mild encephalopathy/encephalitis with reversible splenial lesion type 1) to more diffuse involvement of corpus callosum and...
