Botulism is rare neuroparalytic disease caused by botulinum toxin, one of the most toxic substances known. Foodborne botulism is caused by consumption of foods contaminated with botulinum toxin. The clinical manifestations are flaccid, symmetrical, descending paralysis affecting cranial and peripheral nerves. The only specific treatment is botulinum antitoxin. We report the case of a 37-year-old man with gastrointestinal manifestations and posterior cranial nerve palsy who was diagnosed with botulism infection. Clinicians should be aware of rare causes of infection and determine the aetiology of symptoms.
Learning points: Botulism remains a diagnostic challenge.Misdiagnosis of early cases suggests sporadic cases are overlooked.Timely clinical diagnosis is critical for treatment decisions as botulinum antitoxin cannot reverse existing paralysis.
