Kawasaki disease-associated MERS: Pathological insights from SPECT findings

We report for the first time the single photon emission computed tomography (SPECT) findings of a patient with clinically mild encephalitis/encephalopathy with a reversible splenial lesion (MERS) associated with Kawasaki disease, which showed hypoperfusion of the bilateral cingulate gyri, thalamus, basal ganglia, brainstem, and cortex of the frontal lobes. These findings indicate that the pathogenesis of MERS is based on cerebral hypoperfusion due to vasculitis or cerebrovascular dehydration. (C) 2011 The Japanese Society of Child Neurology.
