We report a case of rhabdomyolysis associated with Mycoplasma pneumoniae pneumonia in a 37-year-old Sri Lankan man who presented to the emergency department with complaints of feverishness, shortness of breath, cough, and generalised muscle pain. He had a serum creatinine kinase of 14 220 U/L, serum myoglobin of 1822 ng/mL, and serum creatinine of 195 µmol/L. His chest X-ray revealed bibasilar interstitial infiltrates. The antimycoplasma antibody titre was high. The patient was successfully treated with aggressive intravenous fluid replacement and azithromycin. The outcome was rapidly favourable, allowing us to discharge the patient 12 days after admission. On discharge, the serum creatinine kinase was 924 U/L and the creatinine was 126 µmol/L; the chest examination was unremarkable.
