title: Sphenochoanal polyp presenting with concomitant nasal polyps.
abstract: A sphenochoanal polyp is a rare lesion that originates in the sphenoid sinus. It occurs most often in adolescents and young adults. We present what to the best of our knowledge is the first reported case of a sphenochoanal polyp associated with concomitant nasal polyps. The patient was a 54-year-old man who presented with bilateral nasal obstruction, possible obstructive sleep apnea, and an altered voice, all of which had likely been caused by the presence of a massive left sphenochoanal polyp and bilateral grade III anterior and posterior ethmoid polyps. Because the patient had dilated cardiomyopathy, he was not a good candidate for general anesthesia. Therefore, the polyps were removed endoscopically under local anesthesia. The sphenochoanal polyp measured 7.5 cm in its greatest dimension and weighed 41 g. The patient remained symptom-free at the 1-year follow-up. The presentation of a sphenochoanal polyp is similar to that of the more common antrochoanal polyp, but the two can usually be differentiated on computed tomography. Endoscopic sinus surgery allows for complete removal of the polyp, including its site of origin, which minimizes the risk of recurrence.
