A-C are magnetic resonance imaging findings along the treatment period. A shows fluid-attenuated inversion recovery images at presentation, 7th day, and 15th day, from left to right. Note that high signal intensities involving bilateral insula intensify over time. B shows diffusion-weighted imaging at presentation, 7th day, and 15th day, from left to right. The red circle indicates the evolution of ischemic stroke lesion in the right frontal lobe, which developed on the 7th day and normalized on the 15th day. A and B show different aging stages of each lesion, supporting that the newly developed focal diffusion restriction in B is more likely due to an ischemic nature. C shows arterial spin labeling signals at presentation and two months after seizure resolution, from top to bottom. Note that the focal increase in bilateral insula, suggestive of ictal perfusion increase, is resolved. D shows the electroencephalogram findings of the patient. High amplitude polymorphic delta activities from the right frontotemporal area evolving to generalized 1-2 Hz spike-wave discharges were noted. The blue arrow indicates seizure onset from the right frontal and anterior temporal region. E is a chest computed tomography (CT) finding at presentation, which shows patchy ground-glass opacities in the right upper lung field, suggestive of COVID-19 pneumonia. F is a follow-up chest CT on day 10. Previously seen COVID-19 pneumonia is completely cleared
