Post-Radiation Sphenoidal Mucocele in a Patient Treated for Nasopharyngeal Cancer

Abstract

The paranasal sinus mucoceles are epithelial-lined cystic lesions containing mucus or mucopurulent fluid. Several theories have been advanced to explain their occurrence. Previous trauma and sinus surgery are the most common cause. Mucoceles following radiotherapy are rare. We report the case of a sphenoidal mucocele in a 62-year-old woman who had received radiotherapy 13 years ago for a nasopha-ryngeal carcinoma. Marsupialisation through an endoscopic transnasal approach was performed. No evidence of recurrence seen after 12 months of follow-up.
