Intramedullary spinal abscess: a case report with a review of 53 previously described cases.

A patient suffering from intramedullary spinal cord abscess associated with an infected dermal sinus, meningitis, and low-lying spinal cord, underwent laminectomy and drainage, after which there was marked improvement. Review of previously reported cases provides a better understanding of this process. The embryology and anatomy of cutaneous lumbrosacral defects are discussed with reference to their potential for subsequent infection and possible association with severe neurological dysfunction. Prophylactic intervention is recommended.
