Orbital and periorbital cellulitis

Case contributed by Dr Bruno Di Muzio


Patient for four days with fever, hyaline rhinorrhea, dry cough. After medical began three days ago an homeopathic treatment. A slight swelling began three days ago on left eyelid. In a new consultation was orientated to use eye drops, but the condition worsened and now can not open the left eye.

Patient Data:

Age: 2
Gender: Female
Race: Caucasian
Modality: CT

On images we can see increased attenuation of fat planes of left peri-orbital area with extraconal extension along the medial rectus muscle. It`s also noted a slight compression of the inflammatory process on the orbit. The intraconal region is preserved and there is no extension to the central nervous system.

Obs.: The radiology technologist was warned by a superior brain acquisitions, since the CT was requested for face and orbits. We must think in ALARA principles.

Case Discussion:

Orbital cellulitis is a postseptal infectious process most commonly caused by paranasal sinusitis, which spreads to the orbit via a perivascular pathway1.

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 adnexa1.
