Five patients with spinal epidural abscess were evaluated with MR imaging. The lesions were best visualized on T1 weighted images with gadopentetate dimeglumine. In all five cases, peripheral enhancement surrounded a central focus of low signal intensity, representing necrotic abscess. In three cases, initial MR imaging showed normal appearance or only hyperintensity of the intervertebral disk. But a epidural abscess could be demonstrated clearly in each patient on follow-up MRI. Therefore, repetitive examinations may be warranted if there is suspicion of intraspinal infection on clinical grounds, even if the initial MRI scans show no abnormality.
