Antrochoanal polyp (ACP) is a common unilateral benign lesion that originates from the maxillary sinus mucosa and protrudes through the choana into the nasopharynx. Patients usually present with progressive unilateral nasal obstruction. Rarely, bilateral ACPs could be encountered in clinical practice. It is important to recognize such unusual entity to spare patients unnecessary investigations and prolonged medical and aggressive surgical treatment. 
Generally, ACP is managed surgically with complete excision including the mucosa of origin to reduce the risk for recurrence. In this report, we present a rare case of bilateral simultaneous ACPs that was managed successfully with endoscopic excision. Review of the literature as regards the etiology, pathophysiology, different clinical presentations, and management aspects of ACP is also presented.
