Subsequent CT scan and ultrasound-guided puncture confirmed a left lumbar PA. mNGS detected the presence of\n                      <jats:italic>Streptococcus agalactiae<\/jats:italic>\n                      , which was negative on conventional culture. The patient was successfully treated with vancomycin for 5 weeks, with no recurrence at 3-year follow-up. Case 2: A 56-year-old woman with a 10-year history of T2DM presented with poor appetite and fatigue. CT imaging identified a left lumbar PA along with perirenal infection. Pus from ultrasound-guided puncture for conventional culture and mNGS detected the presence of\n                      <jats:italic>Staphylococcus aureus<\/jats:italic>\n                      . Treatment with oxacillin and vancomycin led to clinical resolution.
