This coronal (from the front),contrast-enhanced,T1-weighted MR image demonstrates an enhancing mass (red arrows) involving the nasal septum,middle meatus and lateral nasal wall. It has blocked the normal drainage of the maxillary sinus,which is opacified (yellow arrow),lacking normal aeration. Inverted papillomas usually occur on the lateral nasal wall or middle meatus and may extend into paranasal sinuses. They may contain HPV 6 or 11,possibly with EBV. These are benign epithelial tumours that grow outward in finger like projections. About 10% of these tumours are associated with coexistent squamous cell carcinoma. They are locally invasive | |
