Rasmussen syndrome (RS) is a clinical diagnosis characterized by persistent focal seizures in a previously healthy child. Occasionally, the typical features of RS may be followed by another diagnosis. We discuss the course of a 12-year-old girl who presented with RS but was later diagnosed with CNS granulomatous disease and NOD2/CARD15 mutations. Her response to infliximab suggests that it should be included in immune-modulatory therapies used to treat these refractory disorders. ©2007AAN Enterprises, Inc.
