Brain Abscess due to Staphylococcus lugdunensis in the Absence of Endocarditis or Bacteremia

Abstract

Staphylococcus lugdunensis has been recognized to be a microorganism potentially more virulent than other coagulase-negative staphylococci. We report the case of a patient who presented with a single, large, right, frontoparietal abscess that evolved despite conventional antibiotic treatment. Bacteremia and endocarditis were excluded. After surgical treatment, S. lugdunensis sensible to trimethoprim-sulfamethoxazole was isolated, and the patient responded favorably to treatment. Although the ability of S. lugdunensis to produce brain abscesses has been recognized, we report a case of a brain abscess in the absence of bacteremia or endocarditis.
