Cervical epidural abscess.

We present 3 new cases of cervical epidural abscess (CEA), a rare condition, along with a review of 12 other case reports. The average patient age was 45 years; just over half were male. The abscesses usually involved the mid to lower cervical region and extended an average of three to four segments. Neck stiffness was present in all patients; root pain and paresthesias were present less often. Weakness of one to four extremities developed in all but one patient. Sensory levels were frequently present, sometimes below the site of the lesion. All but two patients were febrile. All but two had elevated CSF protein, and all but two had a pleocytosis; myelography always revealed a complete or partial block. Staphylococcus aureus was the causative organism in 8 of 11 patients. CEA should be considered in a patient with neck stiffness, paresthesias, and/or radicular pain so that CT or myelography followed by surgical decompression and/or antimicrobial drugs can be initiated before prolonged weakness develops. One of our patients developed a syrinx causing a new neurologic deficit 3 years after treatment. Delayed syringomyelia, a rare complication of extramedullary lesions, lends support to vascular occlusion as the major mechanism of damage in epidural abscess.
