Persistent radiographic venous attenuation after superior ophthalmic vein thrombosis from pediatric orbital cellulitis.

Superior ophthalmic vein thrombosis (SOVT) is a rare and potentially sight threatening condition that arises from infectious, autoimmune, hypercoagulable, or traumatic causes. With timely diagnosis and treatment, the prognosis for visual and functional recovery is good, though permanent functional and visual loss can occur. We report a case of left septic SOVT in a pediatric patient with radiographic evidence of a small caliber ipsilateral superior ophthalmic vein on MR imaging, 2 and 4 months after full clinical recovery. This radiographic appearance of the superior ophthalmic vein after treatment, in a patient with full recovery, has not previously been reported. Recognition of this persistent change in the caliber of the ipsilateral vein is important to avoid radiographic confusion with contralateral venous congestion.
