Abstract:
Objective To explore the clinical characteristics of rotavirus associated mild encephalopathy/encephalitis with reversible splenial lesion(RAMERS).Methods RAMERS cases were collected from December 2017 to January 2018 at the Department of Neurology,Jiangxi Children's Hospital.The clinical and electroencephalogram characteristics of 14 patients with RAMERS were retrospectively investigated.Data was analyzed by using SPSS 19.0 software.Results Fourteen cases of RAMERS were tested,9 males,and 5 females,with the average age of (27.00 ±6.45) months,and all cases suffered from the generalized tonic-clonic seizures,57.14％ (8/14 cases) had cluster seizure (at lest 2 times/day),convulsions occurred (3.14 ± 1.29) days after gastroenteritis,and 64.29％ (9/14 cases) had pathologic fever (38 ℃ or higher).The background of electroencephalogram(EEG) was characterized by nonspecific rhythmic slow waves in 10 cases (71.43 ％,10/14 cases),normal in 3 cases (21.43 ％,3/14 cases),and interictal EEG performed in 1 case(7.14％,1/14 cases) which was characterized by focal discharges of spikes in the forehead,central,and all of the EEG manifestations go back to normal after 2 weeks.Twelve patients' brain MRI showed solitary splenium of corpus callosum lesion,and two showed splenium of corpus callosum and bilateral symmetry white matter lesion.Conclusions RAMERS is a special type of reversible splenial lesion syndrome,which occurs predominantly in infants and young children.It is characterized by gastroenteritis,benign infantile convulsion,cluster seizure and nonspecific rhythmic slow waves in the background of EEG.Prognosis is usually excellent.Head MRI reexamination is not recommended as a routine procedure to avoid overtreatment.
