Rhabdomyolysis can lead to acute kidney injury (AKI), primarily due to myoglobin-induced tubular damage. We present a case of slowly progressive rhabdomyolysis following SARS-CoV-2 infection in a 28-year-old male who was monitored through serial serum creatine kinase (CK) and myoglobin levels. Despite prominent CK elevations, the patient did not develop AKI, probably due to disproportionately mild serum myoglobin elevation with distinctive cyclic spikes. This case underscores the informative value of frequent monitoring of both CK and myoglobin to assess muscle damage severity and AKI risk in rhabdomyolysis, particularly with viral infections like COVID-19 that can cause delayed-onset muscle injury.
