Radiology in Focus Optimum imaging for sinonasal malignancy
A combination of computed tomography (CT) and magnetic resonance imaging (MRI) is now established as the optimum assessment of sinonasal malignancy. CT and MRI are of particular value in assessing the skull base, orbit and pteryo-palatine and infratemporal fossae. Although MRI offers better differentiation of tumour from surrounding tissue and uid, coronal CT is still required for the demonstr...
متن کاملEndoscopy versus imaging: Analysis of surveillance methods in sinonasal malignancy.
BACKGROUND The purpose of this study was to assess the utility of imaging and endoscopy in posttreatment surveillance of sinonasal malignancies. METHODS We conducted a retrospective analysis of primary sinonasal malignancies diagnosed between 2000 and 2014. Posttreatment surveillance included nasal endoscopy and imaging (MRI, CT, and positron emission tomography [PET]/CT). Positive predictive...
متن کاملEpidemiological Survey of Sinonasal Malignancy in North-East Iran
Introduction: Sinonasal malignancies are uncommon neoplasms with several histological subtypes. These malignancies have a poor prognosis and, because of the nonspecific nature of the symptoms, most patients are diagnosed late when the disease is already at an advanced stage. Therefore, most sinonasal malignancies tend to be treated with surgery and postoperative radiotherapy. Understanding the ...
متن کاملAn orthotopic murine model of sinonasal malignancy.
PURPOSE Malignant sinonasal tumors are clinically challenging due to their proximity to vital structures and their diverse histogenesis and biological behavior. To date, no animal models accurately reflect the clinical behavior of these malignancies. We developed an orthotopic murine model of sinonasal malignancy that reproduces the intracranial extension, bony destruction, and spread along neu...
