Abstract：
:This article addresses the various epithelial tumors of the nasal cavity and paranasal sinuses. It emphasizes the radiologic evaluation of patients with these tumors and the radiologic findings of importance. The advantages and disadvantages of the use of computed tomographic (CT) and magnetic resonance (MR) imaging in this evaluation are stressed.
