Nocardia cyriacigeorgica abscess of the conus medullaris in an immunocompetent host.

Conus medullaris abscesses are a distinct and rare subset of spinal intramedullary infections. We report a patient with a pyogenic abscess of the conus from which we cultured Nocardia cyriacigeorgica following operative evacuation. This is the first report identifying this species as a pathogen in conus abscess formation.
