CASE HISTORY / CLINIC:
78-year-old patient with purulent discharge from the left nose. Partly pressure pains in the orbita, and over the frontal and maxillary sinuses. A reddish/bluish tumor occupying the entire left nasal cavity and which easily bleeds when touched was found during endoscopy.



FINDINGS:
The contrast-enhanced axial CT scans at soft-tissue and bony windows demonstrate a hyperdense, contrast-enhancing mass lesion in the anterior portion of the nasal cavity and in the left maxillary sinus. The wall of the maxillary sinus is laterally discontinuous, the mass extends into the masticatory space. The extension beyond the lateral wall of the maxillary sinus is best viewed in the coronal reformation images(pictures at the bottom).


DIAGNOSIS:
Malignant melanoma of the left nasal cavity and left maxillary sinus.

DIFFERENTIAL DIAGNOSIS:
Other malignant tumors of the paranasal sinuses.
