Sphenochoanal polyp is a rare entity which originates in the sphenoid sinus cavity and extends into the choana via the ostium. It presents in a similar manner to the more common antrochoanal polyp. Radiological examination is necessary to differentiate between these two types. We present a case of sphenochoanal polyp and review the clinical, radiological and pathological features. The role of endoscopic sinus surgery is emphasised.
