We report a patient with multiple brain abscesses due to Staphylococcus cohnii. While these brain abscesses markedly responded to the antibiotics, this patient was subsequently suffered from subcutaneous inflammatory nodules in the adipose tissue, which diagnosed him as having Weber-Christian disease (WCD). This is the first report that subcutaneous inflammatory nodules in the adipose tissue, which lead the diagnosis of WCD, followed multiple brain abscesses. To our knowledge, S. cohnii has not yet been reported to cause multiple brain abscesses in humans. Although the etiology of WCD is unknown, an immune mechanism has been implicated in the pathogenesis. Therefore, we should notice that patients with WCD could be immunocompromised hosts with a higher risk to suffer from severe opportunistic infections.
