Altered matrix of the opposing parts of LV1 and LV2 vertebral bodies displaying T1 hypo- and T2 hyperintense signals. This is associated with irregular (eroded) opposing end plates, narrowing of LV1/2 disc with central T2 hyperintense focus lacking a central nuclear cleft, Intra-spinal extra-dural spindle-shaped soft tissue component extending from the superior end plate of LV1 to the inferior end plate of LV2 compressing the anterior thecal aspect and bilateral paravertebral soft tissue components also seen infiltrating the medial aspect of psoas muscle on both sides.
After contrast administration, the involved parts of the vertebral bodies, the intervertebral disc and the involved extra-osseous components showed homogenous enhancement.
Spondylodiscitis most commonly affects the lumbar spine. it can progress to abscess formation and residual deformity. MRI is the modality of choice for reliable diagnosis and for differentiation from similar diseases.
