Stroke as the Sole Manifestation of Covid-19 in an Argentinean Patient

Background— Ischemic stroke has been reported in patients with Coronavirus Disease 2019 (COVID-19) who also
have other symptoms of COVID-19. Ischemic stroke has very infrequently been seen in patients with asymptomatic
COVID-19.
Case Description— A 80-year-old man presented sudden onset of moderate left faciobrachial weakness. He did
not have any sign or symptom related to COVID-19. Brain magnetic resonance imaging revealed a small right fron
-
tal infarction. Chest computed tomography scan did not have any findings suggestive COVID-19. Nasopharyngeal

swab analyzed using polymerase chain reaction confirmed Severe Acute Respiratory Syndrome Coronavirus (SARS-
COV-2) infection. Paroxysmal atrial fibrillation was detected during hospitalization and oral anticoagulation was

started.
Conclusion— Screening for SARS-COV-2 infection may need to be considered in all patients with acute ischemic
stroke.
