At the L1-L2 intervertebral disc unit, there are erosions involving the inferior endplate of L1 and superior endplate of L2 with disc height loss and mild L1 vertebral body height loss/compression. Focal kyphosis is seen as a result. Findings are in keeping with spondylodiscitis.
There is paravertebral and psoas muscle soft tissue thickening and inflammatory changes suggestive of phlegmon with a very small fluid collection extending into the adjacent left psoas muscle. No epidural collection is noted.
