Case report of septic pulmonary embolism caused by Staphylococcus aureus combined with multidrug-resistant pulmonary tuberculosis and bronchial tuberculosis

This case report describes the presence of septic pulmonary embolism (SPE) in an older woman with diabetes whose initial manifestation was acute sepsis. She underwent computed tomography (CT) imaging, blood metagenomic next-generation sequencing (mNGS), and bronchoscopy, and was diagnosed with SPE secondary to Staphylococcus aureus -positive bacterial infection, combined with multidrug-resistant pulmonary tuberculosis and bronchial tuberculosis. In this case report, we focused on the clinical presentation and CT imaging features of SPE, and the application value of mNGS. This case study suggests that CT combined with mNGS has value in the timely diagnosis and management of SPE in patients with diabetes with severe pneumonia caused by mixed infection with multiple pathogenic pathogens.
