COVID-19 Associated Vertebral Osteomyelitis Caused by Aspergillus Species—A Case Series

Coronavirus Disease (COVID-19) associated fungal infections including pulmonary aspergillosis, mucormycosis and other invasive fungal infections have been increasingly described in the current pandemic. Aspergillus osteomyelitis is a rare clinical form of aspergillosis. Most cases of Aspergillus osteomyelitis are reported in immunocompromised patients. We describe four cases of vertebral osteomyelitis caused by Aspergillus species in the post COVID-19 setting. To the best of our knowledge, Aspergillus vertebral osteomyelitis has not been described in the post COVID-19 setting. None of the four patients described in this series were immunocompromised and all of them had received steroids during their hospitalization for COVID-19 pneumonitis. Vertebral osteomyelitis caused by Aspergillus species is a rare clinical manifestation of Aspergillosis. It requires a high index of suspicion and prompt efforts to establish a diagnosis. For a clinician involved in assessing a patient with Spondylodiscitis, the work up must not be limited to testing for Tuberculosis. Every attempt must be made to establish the microbiological diagnosis. Combined medical and surgical management is generally needed for Aspergillus osteomyelitis.
