Asymptomatic Rhabdomyolysis in a Young Adult With COVID-19

The novel coronavirus disease 2019 (COVID-19) is an ongoing pandemic. Although COVID-19 is frequently associated with respiratory symptoms and complications, multiple extrapulmonary manifestations have been identified since the beginning of the pandemic. Rhabdomyolysis has been described in the literature as one of the extrapulmonary manifestations of COVID-19. Herein, we describe a 21-year-old male patient who presented with cough and fever secondary to COVID-19 confirmed by positive reverse-transcription polymerase chain reaction (RT-PCR) for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The patient presented with an extremely elevated creatinine kinase (CK) of 53,886 U/L (normal 10-170) without any classical symptoms of rhabdomyolysis or deterioration in his kidney function. He was successfully managed with aggressive intravenous fluids. The aim of reporting this case is to highlight the importance of including total CK in the initial evaluation of COVID-19 patients.
