Most cases of orbital cellulitis arise from sinusitis.
CT of orbits and sinuses with axial and coronal views with and without contrast is diagnostic modality of choice.

FIG. 11.34. Orbital cellulitis. This young girl has erythema and edema in the periorbital area (A), which could be caused by either orbital or periorbital infection. However, she has limitation of the extraocular muscles, which characterizes orbital cellulitis, as shown when she is staring straight ahead (B) and gazing upward (C). D: A computed tomography scan of the orbits demonstrates a mass lesion along the medial wall of the orbit in a child with ethmoid sinusitis and orbital infection....

FIG. 15.2. Orbital cellulitis involving the medial rectus muscle. This 5-year-old boy presented with 2 days of fever and eye pain. A: When examined, he cried and refused to look to his right. B: Computed tomography shows thickening of the left medial rectus muscle and a small subperiosteal fluid collection as well as adjacent sinus disease.

FIG. 11.35. Periorbital cellulitis. This boy has pronounced erythema and edema of the periorbital region. Without checking for proptosis and limitation of extraocular movements, periorbital cellulitis and orbital cellulitis appear indistinguishable. In some cases, a computed tomography scan is required to make the differentiation.
