Reversible EEG changes during rotavirus gastroenteritis

Rotavirus can cause seizures and encephalopathy in infants and young children. We report reversible EEG abnormalities in a 2 year and 7 month old boy who had a single seizure during rotavirus gastroenteritis. His EEG showed bilateral independent temporoparietal sharp waves. The EEG was normal 10 days after the first EEG and the patient has been followed with no neurological sequelae. The EEG literature in children developing seizures secondary to rotavirus infection including ours suggest the involvement of mostly posterior cerebral areas. The localization and reversibility of the process can enlighten the pathophysiology underlying this disorder.
