Mild Encephalitis/Encephalopathy with Reversible Splenial Lesion Type II with New Spectrum

Abstract

Mild encephalitis/encephalopathy with reversible splenial lesion (MERS) is a clinicoradiological entity characterized by mild encephalopathy with typical radiological findings. We report a case of 10-year-old male child who presented with abnormal body movements and altered consciousness. MRI revealed typical Middle Eastern respiratory syndrome (MERS) type II lesions. On follow-up, although patient improved clinically with reversal of MERS type II lesions; however, multiple punctuate blooming foci, suggesting microhemorrhages, were seen on imaging in bilateral cerebral hemispheres. This has not been documented yet and signifies a new spectrum of MERS.
