Among nasal and paranasal malignancies, squamous cell carcinoma (SCC) is the most common histology. Other nasal and paranasal malignancies are diverse and relatively rare. However, it is important to understand their imaging features in order to differentiate among them and from benign lesions. Computed tomography (CT) and magnetic resonance (MR) imaging play an important role in characterization and in the assessment of the extent of the disease and involvement of adjacent and distant structures. Familiarity with the CT and MR imaging features of various nasal and paranasal malignancies will facilitate accurate diagnosis and staging. The purpose of this exhibit is: 1. To learn clinical characteristics and incidence of each uncommon nasal and paranasal malignant tumor 2. To review the imaging features of uncommon nasal and paranasal tumors 3. To learn how to differentiate among these uncommon malignancies and from benign lesions

 General epidemiology of nasal and paranasal malignant tumors  Clinical characteristics and CT/MR imaging features of common and uncommon nasal and paranasal malignant tumors     -Malignant melanoma, olfactory neuroblastoma, solitary fibrous tumor, carcinosarcoma, rhabdomyosarcoma, etc.  Differential diagnosis
