Abstract
AbstractVarious pathological entities may manifest on imaging as unilateral or bilateral nasal and/or sinus opacity. The vast majority is represented by inflammatory pathologies, tumors are rare, but they are dominated mainly by benign tumors. Malignant diseases are uncommon, accounting for 3% of tumors of the head and neck. Advances in imaging using preoperative computed tomography and magnetic resonance imaging have been significantly marked in the diagnostic approach to sinonasal pathologies. Surgical modalities are influenced by preoperative knowledge of the nature and topography of the tumor. The aim of this work is to describe the clinical, radiological, and anatomopathological characteristics of sinonasal pathologies expressed by unilateral sinonasal opacity in imaging, to identify the clinicoradiological variables likely to predict malignancy, and to make a correlation between the radiological images and the anatomopathological result.
