Anatomy is the foundation on which the understanding of pathological processes in radiology is based. This article describes the anatomy of the sinonasal region and the clinically relevant anatomical ...variants, highlighting the need for multiplanar reconstructions as a routine part of the examination when reviewing this region.

This article reviews the role of imaging in the diagnosis of sinonasal tumors, illustrating the diversity of tumors affecting this region. The symptoms of sinonasal tumors are nonspecific; imaging ...plays a critical role in distinguishing benign and malignant disease and may occasionally illustrate characteristic radiological features of specific tumors. The patterns of local and distant spread of sinonasal malignancy are demonstrated and the respective roles of computed tomography and magnetic resonance imaging are explained. Critical imaging review areas are discussed together with accurate staging, including orbital and intracranial involvement, which determine the appropriate surgical approach. The sites and patterns of tumor recurrence and the imaging features of recurrent tumor are also discussed.

This article summarizes the imaging features that aid in distinguishing inflammatory from neoplastic disease and benign from malignant conditions. Diagnostic pitfalls are highlighted.
Inflammatory sinus disease is ubiquitous. Patients with recurrent or unilateral disease and those who do not respond to treatment require imaging. Computed tomographic scanning is the mainstay of ...investigation; magnetic resonance imaging is used as a problem-solving tool. The imaging characteristics of sinonasal inflammatory conditions are varied. The role of imaging is to identify patterns of disease, provide a roadmap for the endoscopist, identify anatomical variants that impact on drainage, and exclude aggressive pathology.
