Right Superior Ophthalmic Vein Thrombosis Induced by Pansinusitis.

Superior ophthalmic vein thrombosis (SOVT) is a rare, sight-threatening condition. It can be clinically challenging to distinguish from pre-septal cellulitis or cavernous sinus thrombosis. Imaging is often a key to identifying SOVT, and multi-disciplinary input is paramount to ensuring the optimum outcome. This often involves the paediatricians, ophthalmologists and paediatric neurologists if necessary. We report a case of a young boy with right SOVT that had initially been diagnosed as pre-septal cellulitis. A contrast-enhanced computed tomography scan was performed, as the patient developed limited eye movement on elevation, which showed dilatation of the right ophthalmic vein with pansinusitis. He was successfully treated with anticoagulation and antibiotics.
