Propofol Total Intravenous Anesthesia as an Intervention for Severe Radiation-Induced Phantosmia in an Adolescent with Ependymoma.

Radiation-induced phantosmia has been reported both in children and adults. A fraction of these patients have nausea and vomiting triggered by phantosmia. Radiation-induced phantosmia, although transient, can be distressing enough to prevent a patient from staying still during radiation therapy. To date, specific interventions for radiation-induced phantosmia, including anesthesia, have not been reported. We report for the first time anesthesia as an intervention for transient severe radiation-induced phantosmia, in a 16-year-old girl with ependymoma undergoing proton therapy, and we discuss the pros and cons of techniques for anesthesia and airway management.
