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] EYE Wiki, Radiopaedia, Merck Manual
Key CT Findings in Orbital Cellulitis
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.
