Case Presentation of the Sphenochoanal Polyp: A Rare Entity

Abstract

The spheno-choanal polyp is a rare pathology of choanal polyps that originates in the sphenoid sinus and extends towards the choana via the sphenoethmoidal recess. We report a case of sphenochoanal polyp in a 35-year-old man who presented with chronic bilateral nasal obstruction that had been developing for four years. The incidence of sphenochoanal polyp is extremely rare, especially in young people. Symptomatically, it resembles an antrochoanal polyp. Therefore, adequate preoperative evaluation with endoscopic examination and computed tomography or magnetic resonance imaging is necessary for an accurate diagnosis and appropriate surgical strategy. The treatment of choice is endoscopic surgical excision.
