Splenic abscess caused by Lancefieldella rimae successfully managed with percutaneous drainage and antibiotics: A case report

A 29-year-old man with diabetic nephropathy presented with fever and chills 4 days postdischarge following hospitalization for hyperglycemia. Abdominal computed tomography revealed a splenic abscess. Percutaneous drainage was performed, and intravenous meropenem was administered. Subsequent culture of the drained abscess identified <i>Lancefieldella rimae</i>. Based on the antimicrobial susceptibility results, the patient was switched to oral levofloxacin. This combined treatment led to the resolution of the abscess, with no recurrence after 6 months. This is the first case of a splenic abscess caused by <i>L. rimae</i> successfully managed by prompt percutaneous drainage and appropriate antibiotics.
