Beyond the Usual Suspects: Ethylene Glycol Poisoning Complicated by Rare Neurological Sequelae.

Ethylene glycol poisoning is a known clinical entity with established diagnostic and management protocols. However, instances presenting with rare neurological complications pose diagnostic challenges and necessitate prompt recognition and intervention. This report details the case of ethylene glycol poisoning in a 38-year-old male patient who initially presented with a history of brake oil consumption at his residence, followed by a delayed presentation with vomiting, abdominal pain, and reduced urine output, and subsequently developed unusual neurological sequelae, including unsteadiness, hearing difficulties, and an inability to close his eyes. Diagnostic assessment revealed cerebellar ataxia with bilateral sensory-neural hearing loss and facial nerve palsy. The patient was subsequently managed primarily for ethylene glycol poisoning, with conservative management for the neurological sequelae, and improved with no residual deficits. This case underscores the importance of promptly managing ethylene poisoning to prevent complications and sequelae as well as reduce morbidity for patients.
