Nonketotic hyperglycemic hemichorea‐hemiballismus in a pediatric patient: A case report

Abstract

Abstract Nonketotic hyperglycemic hemichorea‐hemiballismus (NHHH) is an infrequent complication of diabetes mellitus, and rarely occurs in children. We present an adolescent boy with recent diagnosis of type 1 diabetes who presented with hemichorea and brain imaging findings consistent with NHHH. His symptoms resolved with euglycemia and valproic acid after few weeks.
