Abstract

Two previous reports have described restricted diffusion in thrombosed superior ophthalmic veins (SOVs) in patients with cavernous sinus thrombosis (CST). We report a patient who displayed restricted diffusion in both the SOV and inferior ophthalmic vein in CST consequent to a masticator space abscess. The orbital vascular imaging findings added support to the cavernous sinus findings in making the diagnosis of CST. Diffusion-weighted imaging of the orbit is a valuable asset in this setting.
