AimsTo review the clinical presentation and outcome of patients with spinal epidural abscess.MethodsFollowing an index case, additional cases were identified during 1991-6.ResultsThere were a total of seven patients with spinal epidural abscess and an average age of 52 years (range 24-75 years). The abscess locations were cervical (3), thoracic (3) or thoracolumbar (1), and extended on average 4.3 vertebral bodies (range 2-9). Staphylococcus aureus was the aetiologic agent in all of the six microbiologically confirmed cases. Three abscesses arose from adjacent vertebral osteomyelitis, one followed epidural anaesthesia and two arose by haematogenous spread. New spinal or radicular pain were the most frequent early symptoms, later, nerve root weakness or a sensory level. An ESR > 30 mm/hour was consistently present but fever and leukocytosis were absent in some patients. MRI (five cases) and myelography (one case) were diagnostic. Five patients underwent laminectomy and abscess drainage; in three, limb weakness improved markedly post operatively. Three of the four patients with paralysis died, two despite laminectomy.ConclusionsNew spinal pain, radicular symptoms or signs, and a raised ESR were the most consistent early abnormalities in patients with a spinal epidural abscess. Diagnosis at an early clinical stage was associated with a better outcome.
