Aim. To present a clinical case of a 19-year-old patient with community-acquired pneumonia (CAP) caused by Mycoplasma pneumoniae, which was complicated by a rare extrapulmonary manifestation in the form of rhabdomyolysis. Key points. The clinical case demonstrates a variant of mycoplasma CAP in an adult patient. M. pneumoniae infection was confirmed by a positive PCR test. Characteristic is contact with a patient with mycoplasma CAP in an infectious focus, a flu-like onset of the disease. Unlike most mild mycoplasma infections with a minimally expressed clinical picture and inflammatory response, the patient had a long period of febrile temperature and severe intoxication, significant laboratory changes and bilateral polysegmental lung damage. The development of signs of rhabdomyolysis (myalgia, increased creatine phosphokinase (CPK) to 2066 U/L, myoglobinuria) in the acute period of the disease is a rare extrapulmonary manifestation of mycoplasma CAP in adults, dangerous for the development of acute renal failure (ARF). Conclusion. The patient's young age, timely initiation of hydration, and antibacterial therapy aimed at M. pneumoniae made it possible to prevent the development of acute renal failure due to rhabdomyolysis. An increase in CPK, in the absence of other explanations for this phenomenon, should include mycoplasma CAP in the differential diagnosis of rhabdomyolysis.
