Abstract
The objectives of this article are to review the essential anatomy of the paranasal sinuses, describe computed
tomography (CT) and magnetic resonance (MR) imaging approaches to the evaluation of paranasal sinus
neoplasms, discuss imaging features of common sinonasal tract tumors, and examine systemic staging and
surveillance of sinonasal neoplasms using FDG PET/CT and DOTATATE PET/CT.

Keywords: Imaging, sinonasal, neoplasms, sinonasal tract, CT, MRI, PET

INTRODUCTION
Sinonasal malignancies encompass a diverse group of rare and aggressive tumors with distinct imaging
features, histopathological characteristics, and clinical behaviors. Early and accurate diagnosis, precise
staging, and close monitoring are critical for developing effective treatment strategies and improving patient
outcomes. This review highlights the role of imaging-based tumor mapping and tissue characterization in
diagnosing sinonasal malignancies. It also discusses imaging modalities such as FDG PET/computed
