Aims and objectives
Orbital cellulitis can derive from multiple causes such as dental abscess,
trauma,
closed fractures,
periocular surgery,
panophthalmitis.
But,
in the vast majority of cases arise from direct spread of sinus infection specially ethmoiditis.
If there is clinical suspicion of orbital or intracranial complications,
cross-sectional imaging of the orbit and brain is mandatory [1].
Orbital cellulitis may have different clinical presentations,
and several schemes of classification of these types of orbital infections have been published.
Orbital cellulitis is divided into two principal forms: the preseptal form and the retroseptal form.
Management and prognosis differ widely between the two types.
The retroseptal form or “true” orbital cellulitis is a severe disease with potentially disastrous consequences for vision and survival.
The purpose of this study is to describe the CT findings of orbital cellulitis due to ethmoiditis.
