Primary sternal osteomyelitis with bacteremia and distal seeding.

BACKGROUND

Primary sternal osteomyelitis is a rare disease, whereas secondary sternal osteomyelitis is relatively well known as a complication in post-sternotomy patients.

OBJECTIVE

Describe a case of primary Staphylococcus aureus sternal osteomyelitis in an immunocompetent man and its diagnostic challenges, treatment, and complications.

CASE REPORT: A 46-year-old man presented with prolonged sternal pain and swelling, fatigue, and fever. He is diagnosed with primary sternal osteomyelitis with concurrent bacteremia and complicated by local and distant abscess formation. The diagnosis was aided by computed tomography, and treatment consisted of incision and drainage and long-term antibiotics.

CONCLUSION

Primary sternal osteomyelitis is uncommon and often difficult to diagnose. Complications include abscess formation and distal seeding. Diagnosis can be aided by a detailed history and radiography, and treatment may consist of a prolonged course of antibiotics and incision and drainage.
