Abstract

Protein S is a vitamin K-dependent anticoagulant protein. Its deficiency is a rare condition and can lead to deep vein thrombosis, pulmonary embolism or stroke. The incidence of cerebral venous thrombosis (CVT) is low, and in particular, isolated cortical vein thrombosis (ICVT) is very rare. Early diagnosis and treatment are quite important, as ICVT is potentially fatal. There are many known risk factors as pregnancy, puerperium, using oral contraceptive and etc. Here we report the case of a 59-year-old woman with isolated cortical vein thrombosis causing subarachnoid hemorrhage and intracerebral hemorrhage as clinical onset of Protein S deficiency. This case report discusses the possible mechanism and treatment of this extremely rare condition that is an association between ICVT and Protein S deficiency.
