Polypoid lesion arising from the right maxillary antrum, extending into the choana

Case Discussion

The findings are compatible with antrochoanal polyp. The antrochoanal polyp, a benign solitary polypoid lesion, usually arises in a maxillary sinus, opacifying and enlarging the sinus cavity, without bone destruction. It passes through the ostium of the sinus into the choana, and from there into the posterior nasopharynx. The soft tissue mass does not erode or destroy contiguous soft tissue or bony structures.
