|Treatment and Followup:|
|Orbital cellulitis is an acute bacterial infection that most often represents extension of an infection from the paranasal sinuses or eyelid. Pre-septal cellulitis appears as an area of increased signal on T2 weighted images with swelling of the anterior orbital tissues and obliteration of the fat planes. The fibrous septum offers some resistance to extension of the infection into the posterior compartment of the orbit. Often the first sign of involvement of the orbit is slight edema of the orbital fat. In most cases, the cellulitis is confined to the extraconal space, but if left untreated, it can enter the muscle cone and intraconal space and lead to orbital abscess formation.|
