We present a case of successful treatment of Mycoplasma pneumoniae (M pneumoniae) with pulmonary embolism in a child using rivaroxaban and doxycycline, thereby exploring a more appropriate treatment option. A 10-year-old male presented with fever, cough, and chest pain as the main symptoms. M pneumoniae polymerase chain reaction of bronchoalveolar lavage fluid was positive, and computed tomography angiography indicated pulmonary embolism. Azithromycin, doxycycline, and piperacillin-tazobactam were administered sequentially for infection control, while methylprednisolone was given to control inflammation and heparin and rivaroxaban for sequential treatment, resulting in a satisfactory recovery.
