In patients with COVID-19, the most frequent neuroimaging features were: involvement of the medial temporal lobe, non-confluent multifocal white matter hyperintense lesions on FLAIR with variable enhancement and hemorrhagic lesions, and extensive and isolated white matter microhemorrhages. Inclusion criteria were: (i) diagnosis of COVID-19 based on possible exposure history or symptoms clinically compatible, validated with a detection of SARS-CoV-2 by reverse transcriptase-polymerase chain reaction (RT-PCR) assays on the nasopharyngeal, throat or lower respiratory tract swabs; (ii) severe COVID-19 infection defined as requirement for hospitalization and oxygen therapy; (iii) neurologic manifestations; (iv) abnormal brain MRI with acute/subacute abnormalities. Among the eight groups of brain MRI features classification, three main neuroradiological patterns appeared more frequently in patient with severe COVID-19: signal abnormalities located in the medial temporal lobe, non-confluent multifocal WM hyperintense lesions on FLAIR and diffusion with variable enhancement, associated with hemorrhagic lesions, and extensive and isolated WM microhemorrhages. ./cache/cord-319930-ymqnb54a.txt ./txt/cord-319930-ymqnb54a.txt
