title: Iatrogenic acute spinal epidural abscess with septic meningitis: MR findings.
abstract: A contaminated catheter used in epidural anesthesia in a 71-year-old female produced acute epidural abscess and septic meningitis. Methicillin-resistant Staphylococcus aureus (MRSA) was detected in a culture of the epidural pus. Both T1- and T2-weighted MR images showed low intensity mass lesion compressing the thecal sac behind the vertebral body L3. The low intensity lesion was probably pus with gas component. In these low intensity lesions in MR findings with gas component, MR was superior to myelography because it visualized both the degree of compression to the thecal sac and extension of the lesion in all directions.
