Vertebral osteomyelitis and spondylodiscitis. This patient with a previous history of T12 vertebroplasty presents with worsening mechanical back pain and SCC. Sagittal MRI (T1-weighted, post-contrast) shows (A) signal abnormality and enhancement at the T9-12 levels suggesting vertebral osteomyelitis and spondylodiscitis. There are pathological fractures at T10 and T11 with retropulsion and narrowing of the spinal canal. B Axial MRI (T1-weighted, post-contrast) shows total collapse of the T10–T11 disc space and phlegmon adjacent to its anterior and lateral edges
