Epidural abscess treated by PEDI. L4-5 infectious spondylitis was diagnosed in a male patient. Sagittal T1- and T2-weighted and contrast magnetic resonance imaging (MRI) showed L4-5 epidural abscess with compression of neural elements (A). After PEDI treatment, sagittal T2-weighted MRI at 6 months follow-up demonstrated the disappearance of the abscess (B). Lateral computed tomograph revealed L4-5 disc space narrowing leading to spontaneous fusion (C).
