 | Media file 1: T2-weighted MRI shows a large, right psoas abscess with epidural extension. Despite the large fluid collection, results of percutaneous biopsy were culture negative. The patient was treated with intravenous antibiotics before the procedure. |
 | Media file 2: Diskitis/osteomyelitis is seen on this T2-weighted MRI of the lumbar spine, which demonstrates destruction of the L3-4 disk space with the adjacent endplate and/or vertebral body. L3 and L4 vertebral bodies show increased T2 signal, indicating edema and/or infarction. Also shown is a retropulsion of debris, which compresses the thecal sac. |
 | Media file 3: The epidural abscess on this contrast-enhanced T1-weighted MRI demonstrates the loss of disk-space height, which is most prominent at C4-5 and C5-6. A large, peripherally enhancing epidural abscess extends from C5-6 to the C2 level. The thecal sac and cord are compressed. |
 | Media file 4: This image of a CT-guided biopsy of diskitis/osteomyelitis demonstrates extensive destruction and fragmentation of the vertebral body resulting from spondylodiskitis. CT-guided percutaneous needle aspiration and biopsy were performed to obtain material for cultures to direct appropriate antibiotic therapy. |
 | Media file 5: Fluoroscopy-guided radiograph shows how disk aspiration may be used to direct an image-guided procedure. This image also demonstrates the relatively subtle changes of spondylodiskitis on radiography. Although early loss of the disk space may be present, no definite endplate erosion is seen. MRI findings were supportive of infection; the biopsy was culture positive for Staphylococcus aureus. |
