From the information it looks to me like it is first episode of seizures in her. If some has seizures post infection one has to consider the possibility of Acute disseminated encephalomyelitis
of the brain with contrast can diagnose this problem. If MRI is negative other possibilities in her are benign childhood epilepsy
probably precipitated by fever
. EEG done in sleep can in most instances confirms the diagnosis. If EEG and MRI is normal I personally feel medications are not required at this point of time. Keep her under observation and consider the option of medicines if seizure recurs.
