Delayed Spondylodiscitis Presenting as a Skip Lesion

Abstract

Spondylodiscitis is believed to be caused by an infection that affects vertebral bodies and the intervening intervertebral disc. Usually, typical spondylodiscitis involves a mobile vertebra-disc-vertebra unit, and in most cases, the condition is managed successfully by surgical intervention and intravenous antibiotic therapy. Here, the authors report an unusual case of a spondylodiscitis presenting as a skip lesion, which progressed from L4/L5 to L1/L2, despite open surgical biopsy and empirical intravenous antibiotics. Possible pathogenic mechanisms of this unique case are discussed and a review of the pertinent literature is included.
