Clinical case of the month. A 63-year-old woman with lumbago. Eikenella corrodens.

We present a case of facet joint infection (pyogenic facetitis) due to Eikenella corrodens, diagnosed by physical examination, radiography, positive blood cultures, and response to antibiotic therapy. E. corrodens is a very rare cause of spine infection. There are fewer than 20 such cases reported in the literature, only one of which was diagnosed by non-invasive means, and none of which were isolated to the facet joint. We briefly review the microbiology of E. corrodens in addition to the diagnosis and management of spine infection.
