Mycolicibacterium mageritense Bacteremia Following Partial Nephrectomy: A Case Report

Mycolicibacterium mageritense is a rapidly growing non-tuberculous mycobacterium (NTM) that has been associated with multiple human infections, including surgical site, skin soft tissue, prosthetic joint, device-related, pulmonary infections, and bacteremia. The case reported is of a 74-year-old male who underwent partial nephrectomy for a renal mass and subsequently developed postoperative fever. Blood cultures revealed Mycolicibacterium mageritense bacteremia despite the absence of indwelling devices or central venous catheters. The patient was treated with a multidrug antibiotic regimen consisting of imipenem-cilastatin, cefoxitin, and ciprofloxacin, resulting in complete recovery. This case highlights that Mycobacterium mageritense bacteremia could be considered in cases of postoperative fevers without underlying hardware.
