Rhabdomyolysis of the long head of the triceps brachii in a female adolescent after martial arts

Abstract We describe the case of an 11-year-old female patient who was diagnosed as having rhabdomyolysis. Furthermore, rhabdomyolysis in a localized area has not yet been well studied. The diagnosis was made on the basis of the findings from several imaging studies and laboratory data. In addition, interdepartmental consultation was performed to rule out other possible diagnoses. After the diagnosis, the patient was treated with vigorous intravenous hydration and immobilization of the affected area. Regular laboratory follow-ups were performed, and the patient could be discharged with no complication. The patient remained clinically stable at the time of discharge and returned to daily life and sporting activities without any further symptoms at the 1 month after discharge.
