Rasmussen encephalitis (RE) is an inflammatory unilateral progressive medically refractory epilepsy associated with hemiparesis, cognitive dysfunction, and hemispheric atrophy. Here, we present 2 cases from our institution that demonstrate the dual nature of RE in 2 similarly aged children. Overall, 2 types of RE have been described: type 1 has a short prodromal phase and more explosive onset and type 2 has a longer prodromal of partial seizures followed by hemiparesis and atrophy. Younger patients are more likely to fit into the type 1 presentation and have been described as more likely to have dual pathology. Perhaps the patients with a more acute onset are more likely to have a dual pathology as is found in our 2 cases. We review the typical findings in RE and discuss current treatment options, highlighting new experimental treatments.
