Ethylene Glycol Ingestion Resulting in Brainstem and Midbrain Dysfunction

Abstract

Introduction: Ethylene glycol toxicity has produced central nervous system abnormalities including coma, cerebral edema, and cranial nerve dysfunction. Case Report: A 26-year-old male developed widespread brainstem and midbrain dysfunction with corresponding cranial computed tomography findings after ingesting ethylene glycol. The computed tomography scan which was obtained 3 days after ethylene glycol ingestion showed low density areas in the basal ganglia, thalami, midbrain, and upper pons. The neurologic findings in our patient reflected dysfunction of all the areas of hypodensity on the cranial computed tomography scan. A magnetic resonance imaging of the brain obtained 24 days after ingestion revealed bilateral putamen necrosis. The patient's neurologic sequelae resolved over the following 4 months.
