Large Spheno-Choanal Polyp Identified on Oral Surgery Referral Scan

An 83-year-old male with no significant medical history was referred to an oral surgeon due to large maxillary sinuses and the incisive canal observed on a CBCT scan. Upon full-volume review, the radiologist identified a large polypoidal lesion in the left sphenoid sinus extending into the nasal cavity and nasopharynx, suggestive of a large spheno-choanal polyp. Despite the size of the lesion, the patient remained asymptomatic. The radiologist noted that if left untreated, a lesion of this size could cause airway occlusion, breathing difficulty, or extension into the intracranial area. A spheno-choanal polyp of this magnitude is a rare incidental finding in oral and maxillofacial scans, and its detection in an asymptomatic patient underscores the value of full-volume review.
