Aspergillus fumigatus sternal osteomyelitis following cardiac surgery: Case report and literature review.

BACKGROUND

Sternal osteomyelitis caused by Aspergillus spp is uncommon in cardiac surgery patients requiring sternotomy.

CASE PRESENTATION: We report a 77-year-old male with a history of poorly controlled diabetes who was diagnosed with Aspergillus sternal osteomyelitis, three months following an uneventful coronary artery bypass surgery. He underwent multiple debridement surgeries and was treated with voriconazole. Despite a complicated post-operative course, the patient responded well to voriconazole with clinical and biochemical evidence of remission. Unfortunately, he died of an unrelated cause due to decompensated heart failure.

DISCUSSION: Though uncommon, Aspergillus sternal osteomyelitis should be considered in the differential diagnosis of immunocompetent patients with post-operative sternal wound infections and negative bacterial tissue cultures. Management should include a combination of medical and surgical therapy.
