title: Diffusion restriction in thrombosed superior ophthalmic veins: two cases of diverse etiology and literature review.
abstract: Thrombosis of superior ophthalmic veins (SOV) is a well known entity occurring secondary to varied etiologies. We describe diffusion restriction in thrombosed SOV in two cases of different etiologies- bilateral involvement in a patient with septic cavernous sinus thrombosis (CST) and another where embolisation of an indirect carotico-cavernous fistula (CCF) resulted in complete SOV thrombosis accompanied by clinical worsening. Our cases add to the limited literature on diffusion findings in SOV thrombosis.
