A Case of Aspergillus calidoustus Thoracic Spine Osteomyelitis.

Aspergillus infections are of significant concern in patients who are immunocompromised, including transplant recipients. Aspergillus calidoustus is an emerging pathogen reported to cause a wide array of infections. We present a case of A. calidoustus thoracic spine osteomyelitis in a patient with an orthotopic heart transplant (OHT). To our knowledge, this is the first case of A. calidoustus osteomyelitis in a patient with OHT.
