Mild encephalitis / encephalopathy with a reversible splenial lesion is an uncommon condition that mainly affects young patients and children. Epilepsy and the use of antiepileptic medications are considered to be common associations. Other conditions such as infections, high-altitude cerebral oedema, and metabolic disturbances have also been suggested as causes. Concomitant involvement of the corpus callosum and cerebellum is even rarer. We present a patient with a reversible splenial lesion and concomitant reversible cerebellar lesions within the scope of diabetic ketoacidosis and hypernatraemia.
