Mild encephalitis/encephalopathy with reversible splenial and cerebellar lesions (MERS type II) in a patient with hemolytic uremic syndrome (HUS).

Abstract

The typical form of mild encephalitis/encephalopathy with a reversible splenial lesion— called MERS type I—is characterized by a singular, reversible lesion in the midline of the splenium. Very rarely, additional lesions with similar signal characteristics can occur in other brain areas, which is then referred to as MERS type II. We present the case of a patient with a reversible splenial lesion and concomitant reversible cerebellar lesions within the scope of an atypical hemolytic uremic syndrome (HUS).
