Spondylodiscitis associated with recurrent E. coli bacteraemia in an elderly patient: a case report highlighting uncommon pathogen presentation.

Spinal infections are defined as infections within the vertebral column, intervertebral disc space, spinal canal, and surrounding soft tissues. Mycobacterium tuberculosis is the most prevalent pathogen worldwide, and Staphylococcus aureus accounts for more than half of European cases. However, Escherichia coli is a rare organism causing spondylodiscitis. Early diagnosis is vital for the effective management of spinal infections, as it helps prevent mortality and significant morbidity. We present a case of spondylodiscitis caused by E. coli bacteraemia, an atypical pathogen in this setting. The patient's history of cancer and immunocompromised condition complicated the diagnostic process. This case emphasises the importance of thorough evaluation with imaging and highlights the role of multidisciplinary teams in overcoming diagnostic challenges.
