Extensive pulmonary embolism as complication of oligosymptomatic COVID-19: case report.

Although the pathophysiology of coagulopathy associated with the 2019 coronavirus disease (COVID-19) is not well known, occurrence of pulmonary embolism (PE) is frequently observed. However, few cases have been described in the literature in which patients who had asymptomatic COVID-19, with no risk factors for venous thromboembolism (VTE), presented extensive acute PE. We report the case of a patient with asymptomatic COVID-19, complicated by deep vein thrombosis and later by extensive acute PE, suggesting that these conditions should be systematically considered, even in asymptomatic COVID-19 patients with no known risk factors for VTE.

Neurological imaging findings in hospitalized COVID-19 patients: a retrospective observational study in two Brazilian reference centers.

Background: A variety of neurological manifestations have been attributed to COVID-19.

Objective: To investigate the occurrence of neurological symptoms and neuroimaging findings in patients hospitalized in two Brazilian reference centers.

Methods: We performed a retrospective cohort study of patients who had laboratory-confirmed COVID-19 presenting in two hospitals in Brazil between March 4 and July 7, 2020, who underwent brain imaging.
