Multiple Cerebral Venous Sinus Thrombosis as Fist Manifestation of Primary Anti-Phospholipid Antibody Syndrome.

Antiphospholipid antibody syndrome (APS) is an autoimmune disorder, mainly found in young females, presenting with vascular thrombosis and/or obstetric complications. Thrombosis at anatomically significant sites may lead to considerable morbidity and/or mortality. We here present a case of primary APS presenting with sudden onset bilateral multiple cerebral venous sinus thrombosis. The patient, a 17 year old female with no prior rheumatological history, presented with sudden onset bilateral painful blindness and massive proptosis. MRI venography was instrumental in diagnosis. She also had significant thrombocytopenia. Except for the visual dimness, the other symptoms responded to therapy. Such massive cerebral venous thrombosis is extremely rare in primary APS.
