Pyomyositis and muscle abscess due to Salmonella enteritidis in a patient with Behçet's syndrome: a case report.

Salmonella infections usually present with gastrointestinal manifestations including enterocolitis especially in immunocompromised patients. Haematogenous dissemination and abscesses are very rare complications of Salmonella species. This case report documents a patient with Behçet's syndrome (BS) who has pyomyositis due to Salmonella species. A 43-year-old male patient with BS presented to the outpatient rheumatology clinic with bilateral acute-onset lower extremity pain. However, over a short time the pain gradually increased and was accompanied by fever. The magnetic resonance scans demonstrated pyomyositis and muscle abscess in the adductor and obturator muscles. The cultures showed Salmonella enteritidis infection. The patient was successfully treated with antibiotic therapy. This case is important since it is one of the first in the literature to report an adult patient with BS and Salmonella pyomyositis.
