Aspergillus osteomyelitis. Report of a case and review of the literature

Abstract

Aspergillus is a ubiquitous saprophytic fungus seldom pathogenic for normal hosts. Aspergillus osteomyelitis occurs infrequently and is typically limited to patients with predisposing factors, including leukocyte dysfunction, malignancy with neutropenia, steroid or antibiotic therapy, pulmonary aspergillosis, and surgical manipulation. The spine is most frequently affected, and the clinical presentation is nonspecific (50% afebrile). Diagnosis requires demonstration of characteristic, acutely branching, broad, septate hyphae in biopsy material, and culture of Aspergillus. Therapy includes debridement of necrotic bone and loculated purulence combined with amphotericin B and possibly 5-fluorocytosine or rifampin.
