Fig 1. Orbital infection.

Fig 1

Axial (A, B) and coronal (C) contrast-enhanced computed tomography scans of a 43 year-old female show left proptosis, post-septal stranding (dashed arrow, B), and a non-enhancing left superior ophthalmic vein (SOV, dashed arrow,C), compared to normally enhanced right SOV (black arrow, A,C). Opacified sphenoid sinuses suggest an infectious source and lack of opacification in the adjacent cavernous sinuses (white arrows, B) raises concern for thrombosis. Both radiologists diagnosed this case as an orbital infection.
