<i>Salmonella</i> osteomyelitis of the distal radius in a healthy pregnant woman

Although characteristic, Salmonella is a rare cause of osteomyelitis, especially in healthy individuals. A 25-year old primigravida at 29 weeks' gestation noticed pain and swelling in her right wrist. Her leukocyte count was normal, but her C-reactive protein level was slightly elevated, at 1.1 mg dL−1 (normal range, <0.2 mg dL−1). Plain radiography showed an osteolytic lesion in the distal radius, and magnetic resonance imaging (MRI) showed an extraosseous fluid collection with bone edema in addition to the osseous lesion. After a needle biopsy was performed, the skin overlying the lesion became ulcerated at the site of the needle tract. We drained whitish pus from the site; both this pus and the original biopsy specimen grew Salmonella on culture. We diagnosed Salmonella osteomyelitis and began intravenous antibiotic therapy, avoiding oral quinolones to prevent fetotoxicity. Her symptoms resolved, as did the bone edema and fluid collection. Ossification occurred at the site of osteolysis, with localized abnormal signal intensity persisting on MRI. This rare case of Salmonella osteomyelitis was treated without surgery; the patient's pregnancy influenced the treatment course.

Salmonella Osteomyelitis in a Healthy Child: Case Report and Review of Literature

Salmonella osteomyelitis is a rare entity, typically associated with hemoglobinopathies or other underlying disorders. We report a case of Salmonella osteomyelitis of the right knee in an otherwise healthy 1-year-old boy. He received 8 weeks (2 weeks intravenous and 6 weeks oral) of antibiotic treatment, with full recovery.
