CT-revealed Choroidal Effusions as a Sign of Carotid Cavernous Fistula

Fig 1. Images from the case of an 83-year-old man who presented with left eye pain, loss of vision, decreased eye motility, and progressive proptosis.

A, Contrast-enhanced axial CT scan shows enhancing choroidal layers overlying effusions (arrows) and bilateral proptosis with preseptal soft-tissue swelling.

B, Contrast-enhanced axial CT reveals a mildly prominent superior ophthalmic vein (arrow).

C, Angiogram in the anteroposterior projection obtained via direct superior ophthalmic vein injection shows dilated superior ophthalmic veins and bilateral carotid cavernous fistulas.
