Spinal subdural abscess is a rare central nervous system infection with just over a hundred cases reported. It is much less common than spinal epidural abscess. While most case reports have focused on route of infection and treatment options, there have not been any reports that focused on the unique MRI findings of spinal subdural abscess. We describe a case of spinal subdural abscess diagnosed by MRI in a 33-year-old male who presented with headaches after undergoing a microdiscectomy procedure, and review the underlying anatomic features of the spinal meninges which produce the appearance of a spinal subdural abscess.
