Abstract
Objective: We aimed to present the relationship between ischemic stroke and COVID-19, stroke types, and imaging findings in COVID-19 with stroke. Material Method: From March to November 2020, COVID-19 diagnosed in patients with stroke (n=10) was included in the study retrospectively. To eliminate intracranial hemorrhage, a non-contrast computed tomography (CT) was performed for all patients. Then, magnetic resonance imaging (MRI) and Diffusion-Weighted MRI (DWI) (n=10) were obtained. Magnetic resonance angiography was performed in patients whose CT angiography was contraindicated. Clinical information, stroke risk factors, and case imaging results were recorded. Stroke time, size, location (cortical, deep lacunar, and white matter), and vascular territory area were evaluated. Results: The mean age of the 10 patients included in the study was 62±15.10 years. All patients had an ischemic stroke. In total, 4 cases (40%) did not have any risk factors for cerebral vascular disease. Based on DWI results, seven cases were assessed as acute strokes (70%) and three cases as sub-acute strokes (30%). The size of the stroke was 21.80±15.83mm. In 4 cases, the size was extended cortical areas. 3 cases were cortical, 5 cases had a lacunar infarction, 2 cases had cortical and lacunar infarctions. 6 cases were in the posterior cerebral artery territory and 4 cases were in the anterior territory. Conclusion: The presentation of patients with stroke during COVID-19 therapy or after therapy might be considered the hypothesis that the virus led to a stroke, especially in cases accompanied by risk factors.

Summary
Coronavirus disease (COVID-19), which began in Wuhan, China in December 2019 and spread rapidly worldwide, is an infectious disease that often causes acute respiratory distress syndrome. Imaging findings of ischemic stroke associated with COVID-19. It has been reported in the literature that infected COVID-19 patients who were previously healthy and had no risk factors for a cerebrovascular disease may be affected for ischemic strokes after COVID-19 infection or during the treatment.
