Abstract
We report a case of antrochoanal polyp, which has unusual presentation according to the location of the polyp in a 15-year-female patient. The patient came complaining of nasal obstruction, headache, and postnasal drip for a two-week period. The antrochoanal polyp measured 2.5 x 2 cm in the left maxillary sinus and extended to the anterior part of the nasal cavity. CT imaging demonstrated a total opacified left maxillary sinus, maxillary ostium with widening of the left maxillary ostium by polypoid mucosal thickening suggesting an antrochoanal polyp obstructing the left anterior nasal cavity. This case is reported as there are not many articles in world literature describing an antrochoanal polyp presented in the anterior nasal cavity.
