Computed tomographic imaging of a maxillary sinus mucocele in an 8‐year‐old French Bulldog

Abstract

An 8‐year‐old male neutered French Bulldog was referred for continued nasal dyspnea following a staphylectomy revision performed one month prior to presentation. The patient had a prior history of skin allergies and underwent brachycephalic airway surgery performed at one year of age. Computed tomography (CT) revealed an osseous‐encased, cystic mass arising from the right maxillary sinus. Surgical biopsies were performed and a mucocele with sinusitis and glandular hyperplasia was diagnosed. Based on our systematic review of the literature, maxillary sinus mucocele has not been reported in the dog and should be among the differentials for sinus cystic masses.
