OBJECTIVE Immunoglobulin G4 (IgG4) related sclerosing disease (RSD) of the paranasal sinuses is a rare lesion of dense lymphoplasmacytic tissue, with a high proportion of IgG4+ plasma cells. We presented a rare case of IgG4-RSD with isolated involvement of the paranasal sinuses in the absence of multiorgan involvement. METHODS A case report and comprehensive literature review. RESULTS To ou...

Background: Chronic rhinosinusitis (CRS) refers to a group of disorders characterized by inflammation of the mucosa of the paranasal sinuses. Computed tomography (CT) scans used as the gold standard diagnostic modality of nose and paranasal sinus diseases. There has been a lot of studies regarding the anatomic variations leading to pathogenesis of paranasal sinus diseases. Considerable progress...

Introduction: Since demand for computed tomography (CT) examinations is growing, patients are exposed more frequently to ionizing radiation. To reduce the dose delivered to patients in each scan, CT technologists can change the image acquisition parameters. However, this reduces image quality. Present study aimed to optimize and reduce radiation dose in a CT of the paranasal si...

Paranasal sinus anatomical anomalies with unknown etiology are common. Paranasal sinus–related diseases are associated with so high rate of morbidities, it becomes essential to identify the structure and pathophysiology of the paranasal sinuses. Computed tomography (CT) is a valuable tool in displaying its anatomy, any anatomic variations and diseases. As paranasal sinus development is a comple...

Aspergillosis is becoming an increasingly recognized pathogen in the sinonasal tract. The courses of two patients, one seemingly healthy and one with a terminal malignancy, are reviewed. These patients illustrate the clinical course, difficulties in diagnosis, and management of patients with aspergillosis of the sinonasal tract. Aspergillus is a common endogenous contaminant of the upper respir...
