Abstract

A large proportion of patients with coronavirus disease 19 (COVID-19) suffer from excessive coagulation activation and coagulopathy which predisposes them to a wide spectrum of thrombotic events including in situ pulmonary thrombosis, deep-vein thrombosis, and associated pulmonary embolism, as well as arterial thrombotic events. Cerebral venous sinus thrombosis (CVST) have also been reported but in a very small number of cases. This report aims to increase awareness about CVST as a potential neurological thromboembolic complication in patients with coronavirus disease. We report three COVID-19 patients presenting with CVTS. We also review all previously described cases and present an overview of their demographic, clinical, and diagnostic data. We describe three patients with concomitant coronavirus disease and CVST among 1000 hospitalized COVID-19 patients (2 males, 1female, and mean age of 37 years). One patient was previously healthy, while the two others had a history of chronic anemia and ulcerative colitis, respectively. CVST symptoms including seizure in two patients and headache in one patient occurred day to weeks after the onset of COVID-19 symptoms. Three months of anticoagulant therapy was given for all three patients with favorable outcomes. No neurological sequelae and no recurrence occurred within 6 months after hospital discharge. Our search identified 33 cases of COVID-19 complicated by CVST. The mean age was 45.3 years, there was a slight male predominance (60%), and more than half of cases were diagnosed in previously healthy individuals. All cases of CVT were clinically symptomatic and were observed in patients with a different spectrum of coronavirus disease severity. Headache was the most common complaint, reported by just less than half of patients. There was a high mortality rate (30.3%). CVT is a very rare, but potentially life-threatening complication in patients with COVID-19. It's mainly reported in relatively young individuals with no or little comorbid disease and can occur even in patients who do not display severe respiratory symptoms. Atypical clinical presentations may pose a challenge to the early diagnosis and treatment. High suspicion is necessary as early diagnosis and prompt treatment with anticoagulation in all patients with COVID-19 and CVT could contain the mortality rate and improve neurological outcomes in these patients.
