Radiological diagnosis of spheno-choanal polyp.

ABSTRACT

Spheno-choanal polyp is a rare entity which presents in a similar manner to the more common antro-choanal polyp. There is often difficulty clinically in differentiating the two conditions, although their radiological characteristics are distinct. A case of spheno-choanal polyp is presented and the plain radiograph and the CT findings reviewed.
