Bilateral Lower Extremity Compartment Syndrome Secondary to COVID-19 Myositis in a Young Vaccinated Woman.

Coronavirus disease 2019 (COVID-19) typically manifests with respiratory symptoms and can ultimately progress to severe multiorgan failure. Viral myositis, systemic capillary leak syndrome, and arteriovenous thrombosis are atypical manifestations of COVID-19. We present a case of a 33-year-old woman, fully vaccinated against COVID-19, who developed myositis and shock. She ultimately required bilateral lower extremity fasciotomies secondary to compartment syndrome, presumably from COVID-19 myositis. Although compartment syndrome from COVID-19 myositis has been reported for ocular, hand, and thigh compartment syndromes, this is the first case report showing bilateral lower extremity compartment syndrome secondary to COVID-19 myositis in a fully vaccinated individual. As we learn more about COVID-19 and its extrapulmonary effects, it is imperative to consider all working diagnoses when working up patients. Providers must be aware of extrapulmonary effects of COVID-19, particularly in individuals who might deviate from traditional symptoms
