causing spinal subdural empyema.

is a recently described species and genus of bacterium in the Corynebacterineae suborder which is Gram-stain positive, partially acid-fast and anaerobic. Very few cases of human infection due to this organism are described and here we seek to add to the limited medical literature. We report the case of a 2-year-old girl who presented with an infected spinal dermoid cyst secondary to which required surgical drainage and a long course of antibiotics. We encountered diagnostic and therapeutic difficulties because this is a fastidious organism which was difficult to culture and ultimately required molecular detection and identification. To the best of our knowledge, this is only the seventh reported case of causing human infection worldwide and the first in the UK. This is the first reported case of infection in a child and the second reported case of this organism causing spinal infection.
