CT of sinusitis with preseptal cellulitis and a subperiosteal abscess
Axial CT with contrast of the orbits (above) shows opacification of the ethmoid sinuses and sphenoid sinus along with right preseptal soft tissue swelling. There is a fluid collection with rim enhancment medially next to the wall of the right ethmoid sinus which is better seen on the coronal CT (below).
