Clinical Presentation: Fever and back pain in a patient with ahistory of drug
abuse.
Comment: The diagnosis of spondylodiscitis was based on aCT-guided biopsy
and positive hemoculture. The most commondifferential diagnoses of paravertebral
masses include: adenopathy,abscess following spondylodiscitis, extramedullary
haematopoiesis,neurinoma and retroperitoneal fibrosis.
Description: The frontal chest X-ray shows bilateral basal linearparenchymal
opacities (discoid or plate atelectasis). The lateralX-ray shows possible vertebral body
collapse between T6 and T7. CTconfirms a perivertebral mass effect with bone
destruction. MRIimages show abnormal signal in the bone marrow and T6-T7 disk, withlow
signal on T1-weighted images and high signal on T2-weightedimages, indicating
inflammation.
