Illustrative images of neurologic complications in older patients hospitalized with COVID-19 pneumonia. a, b, c, d, and e, CT and MRI images of an 89-year-old woman with left-sided hemiplegia. a, Non-contrast head CT did not show early CT signs of ischemia. b, CT angiogram showed occlusion of the right middle cerebral artery (arrow). c, Perfusion CT mean transit time (MTT) images showed prolonged MTT in the entire right middle cerebral artery territory (arrows), whereas perfusion CT derived cerebral blood volume (d) remained symmetric between both hemispheres. e, Diffusion-weighted image of MRI study obtained one day later and after intravenous thrombolysis showed a small area of infarction in the right corona radiata (arrow). f, Non-contrast head CT image of an 84-year-old woman with obnubilation showed an isolated focus of intraparenchymal hemorrhage in the left lentiform nucleus (arrow). No evidence of underlying vascular or tumoral pathology was found on subsequent MRI (not shown)
