Coxiella burnetii, which were positive (IgM-phase I: 1/192 and IgG-phase II: 1/2048). Brain MRI showed a 2.2 cm x 2.0 cm heterogenous ring-enhancing parasagittal lesion in the right parietal lobe consistent with brain abscess (Figure 2). Consequently, the diagnosis of recurrent fevers secondary to brain abscess attributed to Coxiella burnetii culture-negative endocarditis was established.
