Rhinosinusitis CT

Introduction

Overview

Overview

Although a CT scan is not routinely indicated for suspected cases of rhinosinusitis and findings are highly nonspecific, a CT scan is the imaging modality of choice in cases of chronic or complicated rhinosinusitis. Positive CT scan findings are not essential for diagnosis, but negative CT scan findings rules out rhinosinusitis. Findings include mucosal thickening and narrowing of the osteomeatal sinuses.[1][2][3][4]
