Imaging of spondylodiscitis.

BACKGROUND: Spinal infections (pyogenic or non-pyogenic) are increasing in incidence and are a common cause of morbidity in high-risk patients (elderly, immunocompromised patients, diabetic patients, drug addicts, and patients with sickle-cell disease).

AIM: To provide an overview of the radiological features of spinal infections, focusing on magnetic resonance (MR) imaging, and to illustrate the differential diagnosis.

MATERIALS AND METHODS: We reviewed the spine imaging of 118 patients with spinal infections from our files. All patients underwent radiography and MR imaging examinations. computed tomography (CT) was performed in 96 patients.

RESULTS: MR imaging has greatly contributed to prompt diagnosis, thus allowing implementation of timely appropriate treatment.

CONCLUSIONS: Prompt diagnosis and treatment are essential to prevent serious bone and joint destruction, and severe neurologic sequelae.
