Sphenoid Inverted Nasal Papilloma Presenting as Chronic Headaches in a 21-Year-Old Patient: A Case Report and Literature Review

Abstract

An inverted papilloma is a rare, benign tumor that affects the nasal cavity and paranasal sinuses. The maxillary and ethmoid sinuses are the most commonly affected, while the involvement of the sphenoid sinus is rare and may be associated with malignancy. We describe the case of a 21-year-old female who presented with recurring headaches along with dizziness, difficulty concentrating, mild hypoacusis, and occasional nasal congestion. A CT of the sinuses showed a soft tissue lesion in the sphenoidal sinus with extension into the posterior ethmoidal cells. After the biopsy, the patient was ultimately diagnosed with sphenoid inverted nasal papilloma.
