Cholesterol granulomas of the paranasal sinuses are less common. Of the paranasal sinuses, the maxillary sinus is most commonly involved.³ Cholesterol granulomas of the maxillary sinus usually occur in males and are predominantly unilateral.⁴ The presenting symptoms of maxillary sinus CGs may include nasal obstruction, facial pain, and, rarely, clear, golden-yellow rhinorrhea.⁵ Cholesterol granulomas are often expansile lesions that can cause bony destruction and compression of adjacent structures.
