The most common presentation of COVID-19 is fever and upper and lower respiratory tract infection. Myalgia is fairly common in the prodromal phase of the viral illness which self-resolves. There is very scant literature on autoimmune myositis triggered by COVID-19 infection. We report a case of SARS-CoV-2 infection, who presented with progressive muscle weakness with rhabdomyolysis and necrotizing autoimmune myopathy on muscle biopsy. This case report imposes awareness of musculoskeletal autoimmune processes triggered by COVID-19 which requires clinical suspicion for early diagnosis and initiation of treatment.<\/jats:p>","DOI":"10.1136\/bcr-2020-239457","type":"journal-article","created":{"date-parts":[[2021,4,13]],"date-time":"2021-04-13T14:24:27Z","timestamp":1618323867000},"page":"e239457","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":20,"title":["COVID-19 IgG-related autoimmune inflammatory necrotizing myositis"],"prefix":"10.1136","volume":"14","author":[{"given":"Maedeh","family":"Veyseh","sequence":"first","affiliation":[{"name":"Medicine, Jacobi Medical Center, Bronx, New York, USA"},{"name":"Rheumatology, Montefiore Hospital and Medical Center, Bronx, New York, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sai","family":"Koyoda","sequence":"additional","affiliation":[{"name":"Rheumatology, Montefiore Hospital and Medical Center, Bronx, New York, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0410-677X","authenticated-orcid":false,"given":"Bibi","family":"Ayesha","sequence":"additional","affiliation":[{"name":"Rheumatology, Montefiore Hospital and Medical Center, Bronx, New York, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2021,4,13]]},"reference":[{"key":"2025082800343085000_14.4.e239457.1","doi-asserted-by":"crossref","unstructured":"W-j G , Z-y N , Hu Y .
