Case Discussion
The case illustrates typical non-contrast CT scan features of an antrochoanal polyp. One of the complications of the antrochoanal polyp is papillary endothelial hyperplasia which can lead to hemorrhage. The polyp has usually a narrow pedicle but rarely can be seen on CT scan images. The treatment of choice is complete surgical resection of the pedicle.
