Abstract: Mild encephalitis/ encephalopathy with a reversible splenial lesion (MERS)in the corpus callosum is a clinical - radiological syndrome with typical imaging characteristics,which can be divided into 2 types (MERS Ⅰand MERS Ⅱ)according to the affected parts. The main cause is infection in children. Patients can be presented with symptoms that are common for acute mild encephalitis or encephalopathy such as disturbance of consciousness,hea-dache,vomiting,seizure. Brain magnetic resonance imaging(MRI)indicates lesions in the splenium of the corpus callo-sum. The symptoms and brain MRI lesions disappear almost within 1 month,and the prognosis is usually good. Early recognition is necessary and excessive treatment should be avoided.
