Tumors and tumor-like lesions are rare diseases in the paranasal sinuses. There is a great variety of histological types, but only a small number of morphological patterns on imaging. Histology is an important point in therapeutic planning. In most cases it is obtained by sampling, which is not as difficult in the sinonasal area as in other regions of the body. The main task of imaging is an exact estimation of the extent and spread of a lesion. This article discusses the possibilities and limitations of CT and MRI in the assessment of the dignity and spread of paranasal tumors and tumor-like lesions in consideration of necessary therapeutic information. Additionally, an overview of features on imaging of different paranasal tumors and tumor-like lesions is given.
