Brain Edema After Cosmetic Botulinum Toxin Injection: A Case Report.

A 26-year-old woman presented to the emergency department with progressive symptoms including fever, pharyngeal pain, dysphagia, bilateral ptosis, and generalized weakness after cosmetic botulinum toxin injections to the neck. This case report aimed to describe an unusual presentation of botulinum neurotoxin-associated central nervous system involvement. This manuscript is a case review describing the clinical course, diagnostic challenges, and management strategies of brain edema after botulinum toxin type A exposure. Key points include the importance of recognizing nontraditional presentations of botulism in emergency settings, the potential for central neurologic complications after cosmetic procedures, and the critical role of emergency nurses in early symptom recognition, airway management, and multidisciplinary coordination for antitoxin administration and intensive care support.
