Imaging of sinonasal tumors.
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.
