A case of cerebral embolism with Coronavirus disease 2019

Abstract

A 63-year-old man, who had persistent fever for a month, was admitted to the hospital with sudden left arm palsy with a National Institutes of Health Stroke Scale score of 3. Consequently, brain MRI showed hyperintensity of the bilateral occipital, right parietal, and right frontal lobes on diffusion-weighted imaging. Moreover, FLAIR presented hyperintensity of the left occipital lobe. Magnetic resonance angiography detected the deficit of the blood-flow signal of the horizontal segment of the middle cerebral artery. He was diagnosed with acute ischemic stroke. In addition, chest CT showed ground-glass opacities, and test to detect SARS-CoV-2 was positive. Cerebral embolism was suspected. However, the source was unknown. His ischemic stroke was possibly associated with coagulation abnormality caused by coronavirus disease 2019.
