There is increased attenuation of fat planes of the left peri-orbital area with extraconal extension along the medial rectus muscle. It is also noted a slight compression on the orbit. The intraconal region is preserved and there is no extension to the central nervous system.

Case Discussion

Orbital cellulitis is a postseptal infectious process most commonly caused by paranasal sinusitis, which spreads to the orbit via a perivascular pathway 1.

Periorbital cellulitis, which is defined as a preseptal process limited to the soft tissues anterior to the orbital septum, most commonly arises from the contiguous spread of infection from adjacent structures such as the face, teeth, and ocular adnexa 1.
