Acute Neurobrucellosis: Syndrome of Inappropriate Antidiuretic Hormone Secretion and Parkinsonism Presentation

Abstract

Introduction: Brucellosis is a zoonotic infection with high distribution all over the world and has many clinical manifestations, one of which is neurobrucellosis (NB). Case Presentation: Our case was a 78-year-old man who presented acute decreased level of consciousness, acute parkinsonism signs and hyponatremia due to syndrome of inappropriate antidiuretic hormone secretion (SIADH), which was caused by brucellosis. Discussion: Neurobrucellosis is a rare presentation of brucellosis and should be considered when neurological problems cannot be explained by other etiology especially in endemic areas.
