Nasal mass mimicking antrochoanal polyp.
Sphenochoanal polyp is a rare form of choanal polyp. As the name suggests, it originates from the sphenoid sinus and extends down the choana and nasopharynx. If wrongly diagnosed as an antrochoanal polyp, it can lead to unnecessary exploration of the maxillary sinus and incomplete removal of the sphenoid component of polyp. Here we report a case of 40-year-old woman who presented with history of progressive left nasal obstruction and mass in the oropharynx. A diagnosis of sphenochoanal polyp was made on the basis of nasal endoscopy and computed tomography scan. The polyp was removed endoscopically. We discuss the clinical presentation, management and review of the literature of this clinically mistaken entity.
