Imaging findings
Subtle widening of the left paravertebral stripe is seen on chest radiograph. CT reveals bilateral paravertebral soft tissue centered at the disc space, extending across multiple vertebral levels. MRI demonstrates a classic disc-centered inflammatory process with edema involving both adjacent vertebral bodies and extensive paravertebral soft tissue, confirming discitis-osteomyelitis.
Key takeaways
Discitis-osteomyelitis, particularly in patients with a history of malignancy and recent bacteremia, should be considered when paravertebral soft tissue widening is observed, even if subtle. The disc-centered nature of the inflammation with adjacent vertebral body edema on MRI helps differentiate it from metastatic disease, guiding appropriate antibiotic treatment.
