Imaging of the sinonasal (SN) cavities is one of the most frequently performed examinations, primarily for evaluation of presumed inflammatory disease. Although SN neoplasms are relatively uncommon compared to other head and neck tumors, radiologists are likely to encounter these lesions because of the frequency of sinus imaging. Many of these tumors have nonspecific presenting symptoms and imaging features; however, some distinguishing features can help narrow the differential diagnosis. The SN cavities are one of the most histologically diverse areas of the body, with a large variety of neoplasms occurring in the region. Our goal is to discuss some of the more common entities and their characteristic features, as well as some less common lesions that are of greater importance. We also briefly discuss imaging techniques, tumor presentation, classification and management.
