Abstract
Vaccine-induced immune thrombotic thrombocytopenia (VITT) with cerebral venous sinus thrombosis (CVST) has been recently reported after vaccination against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). We present a case of a patient with fulminant CVST and thrombocytopenia after receiving the ChAdOx1 nCoV-19 vaccine. Although the patient received immediate anticoagulant and intravenous immune globulin treatment, he died within 24 h after hospital admission. VITT and CVST are rare conditions; however, the course may be fatal. Therefore, clinicians should be familiarized with the clinical and laboratory features of VITT.
