Sphenochoanal Polyp: A Rare Entity Revealed by CT Imaging

Sphenochoanal polyp is a rare subtype of choanal polyp originating from the sphenoid sinus and extending into the choana through the sphenoethmoidal recess. We report the case of a 26-year-old male with a 4-year history of chronic nasal obstruction successfully managed by endoscopic surgical resection. Postoperative outcomes were favorable. Due to its rarity and overlapping clinical presentation with antrochoanal polyps, comprehensive preoperative assessment—including nasal endoscopy and especially computed tomography (CT) or magnetic resonance imaging (MRI)—is essential for accurate diagnosis and surgical planning. Endoscopic resection remains the treatment of choice.
