Polyp. Coloured computed tomography (CT) scan showing a large polyp in a maxillary sinus. The two maxillary sinuses are air-filled cavities seen here as large black areas underneath the nasal cavity (top centre). The right maxillary sinus (left of image) is largely occupied by the polyp visible as a round blue area at centre left. Polyps are growths,usually benign,that protrude from a mucous membrane. They may need to be removed if they are responsible for symptoms or if they are likely to develop into a malignant growth. Other common sites of polyp formation are the lining of the nose,the cervix,the intestine and the larynx | |
