Abstract

This is a report of six cases of respiratory epithelial adenomatoid hamartoma of the nasal cavities that were characterized by: symptoms of nasal obstruction and dysosmia; endoscopic appearances of bilateral nasal polyposis affecting the olfactory clefts; CT imaging showing enlargement of the olfactory clefts; MRI (rarely reported in the literature) revealing clearly delineated cerebriform tissue filling in the olfactory clefts; histological confirmation in all cases; and recovery after surgical endoscopic resection without the need for associated sinus surgery.

Keywords: CT; MRI; Nasal polyposis; Olfactory cleft; Respiratory hamartoma.
