- Clinical and Neuroimaging Correlation in Patients with COVID-19
This was a retrospective study performed at a large academic hospital in the United States. A total of 641 patients presented to the authors' institution between March 3, 2020 and May 6, 2020, for treatment of coronavirus disease 2019, of whom, 150 underwent CT and/or MR imaging of the brain. CT and/or MR imaging examinations were evaluated for the presence of hemorrhage, infarction, and leukoencephalopathy. Of the 150 patients, 26 (17%) had abnormal CT and/or MR imaging findings, with hemorrhage in 11 of the patients (42%), infarction in 13 of the patients (50%), and leukoencephalopathy in 7 of the patients (27%). Significant associations were seen between abnormal CT/MR imaging findings and intensive care unit admission, intubation, and acute kidney injury.
- Imaging Features of Acute Encephalopathy in Patients with COVID-19: A Case Series
The authors present 5 cases that illustrate varying imaging presentations of acute encephalopathy in patients with coronavirus disease 2019. MR features include leukoencephalopathy, diffusion restriction that involves the GM and WM, microhemorrhages, and leptomeningitis.
