Massive thrombosis of bilateral superior and inferior ophthalmic veins secondary to ethmoidal rhinosunisitis: imaging findings.

Ophthalmic vein thrombosis (OVT) is a rare condition occurring secondary to varied etiologies that commonly presents with proptosis, globe dystopia, ophthalmoplegia, periorbital edema, and occasionally diminished visual acuity. It may be related to inflammation of the orbit or paranasal sinuses. We herein report imaging findings of thrombosed superior and inferior ophthalmic veins in bilateral involvement in a 20-year-old male patient without cavernous sinus thrombosis. He presented with pain, swelling, and blurred vision in both eyes. Magnetic resonance (MR) imaging, cerebral MR angiography, and susceptibility weighted imaging were performed. Bilateral superior and inferior OVT due to a complication of ethmoidal sinusitis was diagnosed in the patient. Anticoagulant and systemic broad-spectrum antibiotic therapy was started. His symptoms were recorded at the end of 14 days of the treatment.
