Superior Ophthalmic Vein Thrombosis Associated With Acute Suppurative Parotitis and Masticator Space Cellulitis: A Case Report and Review of the Literature.

Superior ophthalmic vein thrombosis (SOVT) is a rare phenomenon caused by both septic and aseptic etiologies. Individuals suffering from SOVT commonly present with ophthalmoplegia, proptosis, chemosis, and impaired vision. The superior ophthalmic vein is a valveless vein that drains into the cavernous sinus; for this reason, SOVT can present with dire complications such as cavernous sinus thrombosis in addition to debilitating permanent ophthalmoplegia and permanent vision loss if left untreated. Early accurate diagnosis and treatment of SOVT are of paramount importance in order to improve patient outcomes and to reduce morbidity and mortality. In this paper, the authors present an uncommon case of SOVT associated with acute suppurative parotitis and masticator space cellulitis.
