Contrast-enhanced computed tomography of nose and paranasal sinuses. A, Coronal view showing a heterogeneously enhancing soft-tissue density causing destruction of the midline septum extending into the left nasal cavity, anterior and posterior ethmoid sinuses, and partially filling the left maxillary sinus with retained secretion. There is extension into the right nasal cavity, and there was no skull base or lamina papyracea erosion. B, Coronal view showing soft-tissue density anterior to nasal bone extending into nasal cavity and left maxillary sinus and ethmoid sinuses.

Contrast-enhanced computed tomography of the nose and paranasal sinuses showed a heterogeneously enhancing soft-tissue density over root of the nose with erosion of nasal bone and extension into left nasal cavity and filling left maxillary sinus, anterior, and posterior ethmoid sinuses and extending into right nasal cavity with erosion of bony septum (Figure 1(A) and (B)).
