The value of helical computer tomography and magnetic resonance imaging in the diagnosis of juvenile angiofibroma of the nasopharynx

Juvenile nasopharyngeal angiofibroma (JNA) is a benign tumor that occur most often in males with ger-mination her in the nose and paranasal sinuses (PPN). For getting reliable information in the diagnosis of tu-mor is of great importance of CT and MRI.
