Iatrogenic Botulism in a Child With Spastic Quadriparesis

Abstract

Botulinum toxins are potent neurotoxins used in a variety of neurological disorders. Few pediatric reports have been published to date regarding the potential hazards of therapeutic use of botulinum toxins. We describe the case of a 10-year-old boy who developed systemic weakness following treatment of spasticity with botulinum toxin type B. The patient developed iatrogenic botulism with ptosis, facial diplegia, neck flexor and extensor weakness, and profound hypopharyngeal laxity with respiratory compromise from which he eventually recovered. Clinicians should be mindful of the risk for systemic botulism when using local injections of the neurotoxin.
