Overview
An epidural abscess is a rare suppurative infection of the central nervous system, a collection of pus localised in the epidural space lying outside the dura mater, which accounts for less than 2% of focal CNS infections. [1] It may occur in two different places: intracranially or in the spinal canal. Due to the fact that the initial symptoms and clinical characteristics are not always identical and are similar to other diseases, along with the fact that they are both rare conditions, the final diagnosis might be delayed in time. This late diagnosis comes at great cost to the patient, since it is usually accompanied by a bad prognosis and severe complications, with a potential fatal outcome. According to the location of the collection, the abscess may have different origins, different organisms involved, symptoms, evolutions, complications and therapeutical techniques. [2] The treatment of epidural abscess focuses in two main aspects: reduction of the inflammatory mass; and eradication of the responsible organism. These goals can be reached through a combination of therapeutical approaches, including: aspiration, drainage and antibiotic therapy. An early surgical decompression and drainage, followed by an aggressive antibiotic treatment is the ideal procedure to increase the chances of a better outcome.
Surgery
Several studies have reached the conclusion that the best approach to therapy of epidural abscess, either intracranial or spinal, is a combination of surgical drainage along with prolonged systemic antibiotics (6-12 weeks, IV followed by PO). [3] Due to the importance of preoperative neurologic status, along with the unpredictable progression of neurologic impairment, for the neurological outcome of the patient, decompressive laminectomy and debridement of infected tissues, in the case of SEA, and burr hole placement or craniotomy, in the case of IEA, should take place as early as possible.
