Abstract

   

Background: Paranasal sinus diseases include a wide spectrum of conditions including inflammatory, non-neoplastic and neoplastic causes with a reported incidence of 1 to 4 % of the population

Aims & Objectives: To assess the role of CT in evaluation of inflammatory sinonasal diseases

Materials and Methods: All Patients referred from Department of Otorhinolaryngology for Paranasal Sinus CT to the Department of Radio diagnosis From December 2017 to October 2019

Results: Sinusitis is the most common pathology detected on CT and on final pathological diagnosis followed by polyp.Acute/chronic sinusitis -100% sensitivity and 79.6 % specificity. Polyps - sensitivity of 70.4% and specificity of 98.2%. Fungal sinusitis- sensitivity of 83.3% and specificity of 100%. Mucocele and rhinosporidiosis was diagnosed with 100% accuracy. Inverted papilloma and carcinoma (poorly differentiated)- specificity 100% for both, sensitivity 66.7% and 75 % respectively.

Conclusion: Pathological diagnosis correlated well with the CT diagnosis, proving that it is an ideal modality to evaluate sinonasal pathologies.
