Spinomedullary Weston Hurst Syndrome After COVID-19 and Influenza Co-Infection: A Case Report

Abstract

The neurological complications of coronavirus disease 2019 (SARS-CoV-2, COVID-19) have so far included a range of para- and post-infectious neuroinflammatory syndromes inclusive of all components of the neuraxis and peripheral neuromuscular system. In comparison to the para-infectious manifestations of anosmia, ageusia, encephalopathy, and encephalitis, cases of post-infectious ADEM have rarely been reported and have most commonly affected the supratentorial component with or without spinal cord involvement. In this report, we describe a case of isolated involvement of the cervicothoracic spinal cord and medulla, occurring in association with microhemorrhages and hemosiderin deposition in the medulla, that presented fulminantly and required aggressive immunotherapy to control the inflammatory attack. We compare and contrast this case against prior reports of acute hemorrhagic leukoencephalitis (Weston Hurst syndrome) and review the atypical features of neuroinflammation reported to occur following COVID-19 infection.
