A 52-year-old man initially presented with a several month history of chronic rhinosinusitis that had been refractory to medical therapy, including multiple courses of antibiotics and oral steroids.

The initial computed tomography (CT) showed pansinusitis with complete opacification of the left maxillary sinus.

The patient underwent bilateral endoscopic sinus surgery (ESS) with final pathology demonstrating inverted papilloma (IP) with chronic inflammation.

Subsequently, the patient underwent left revision ESS for removal of residual IP. However, 6 months later a recurrent papillomatous lesion was noted involving the anterior aspect of the left maxillary sinus.

The patient was then referred for further management.
