Mycobacterium chelonae lumbar spinal infection.

A case report of a previously healthy adult patient with a lumbar spinal extradural abscess due to Mycobacterium chelonae is presented. His course of treatment was complicated by recurrent psoas abscesses, as well as multiantibiotic resistance, requiring multiple surgical drainage procedures and antibiotic changes over a 33-month period. Cure was achieved only after aggressive surgical debridement of the abscess.
