Orbital cellulitis is a septic process between the ethmoid and orbitary tissue representing the most frequent cause of unilateral exophthalmos.
(8,9) which occurs due to dissemination of infection from ethmoid to orbitary tissue due to bone refraction arising from osteitis involving the external wall of ethmoid, which corresponds to internal region of the orbit at the level of the lacrimal bone.
Patients suspected with orbitary cellulitis must be immediately explored with imaging techniques like CT scan and hospitalized.
Longacre et al, (14) attributed low incidence of primary malignancy in part admittedly due to
orbitary definitional criteria as it is difficult to distinguish primary tubal carcinoma from primary ovarian or endometrial carcinoma in patients with high stage disease.
