A Case of Spondylolysis and Spondylodiscitis in a Child

A 3-year-old girl presented with a history of low back pain. The initial X ray showed spondylolysis and minimal anterior spondylolisthesis at L5-S1 (Figure 1). Lumbar MRI showed extraforaminal disc protrusion with intervertebral disc height loss, vertebral endplate signal abnormality in L4-L5 vertebral bodies, left soft tissue abnormal signal from L2 to S1 and medial aspect of psoas muscle (Figure 2). CT-guided core biopsy of paravertebral soft tissue, confirmed diagnosis of spondylodyscitis.
