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