Orbital cellulitis CT

Introduction

Overview

Overview

On CT scan of the head, orbital cellulitis is characterized by hyperdensity within low density periorbital fat and generalized elevation of the periobita. CT scan of the orbit is the imaging modality of choice for patients with orbital cellulitis. CT scan is also diagnostic of subperiosteal and orbital abscesses associated with orbital cellulitis.[1][2][3][4][5][6]
