Periodic limb movement disorder: A novel presentation of insulinoma

Abstract

Hypoglycemia because of insulinoma can mimic many neurological disorders including movement disorders during sleep. We present a 54-year-old woman who presented with features typical of periodic limb movement disorder and on detailed evaluation was found to have insulinoma. After surgical therapy for the insulinoma, the movements completely remitted. Hypoglycemia because of insulinoma is a treatable condition that should be considered in the differential diagnosis of movement disorders during sleep.
