Learning Objectives. To describe imaging findings of a wide spectrum of uncommon nasal cavity masses evaluated at our institution by CT, CBCT and MR imaging, clinically and pathologically proven. Background. In this work we present a succinct review of disease illustrated by a retrospective case series of nasalcavity masses, evaluated at our institution. between 2010 and 2013. Patients have been studied with different imaging modalities including multiraw computed tomography (CT), cone beam computed tomography (CBCT) and magnetic resonance imaging (MR) to illustrate the findings and to summarize the main diagnostic keypoints for the differential diagnosis of nasal masses. Clinicopathological correlation is also reported and imaging findings we present have been isthopathologically proven. Images aid in recognition and characterization of the lesions. Many different types of lesions may involve the nasal cavities and imaging studies, CBCT, CT and MR, provide anatomical details and could be helpful first in differentiating benign to malignant lesions and secondary in characterization of the lesion. Referring to non neoplastic lesions, rinoliths, piogenic granuloma and septal mucocele are reported. Referring to benign and borderline tumors osteoma, hamartoma, hemangioma, hemangiopericytoma, cemento-ossifying fibroma, antrochoanal polip and inverted papilloma are reported. Referring to malignant neoplasms intestinal type adenocarcinoma, esthesioneuroblastoma and Non-Hodgkin lymphoma are reported. CONCLUSION. This review of uncommon nasal masses studied with different imaging modalities (CT, CBCT and MRI)should be useful in differential diagnosis of the wide spectrum of nasal tumors and non tumors masses.
