MR 2/26 – T2 hyper intensity of anterior-superior L3 vertebral body
MR 3/6 – Decreased height and T2 signal of anterior L2-L3 disc space with increasing marrow edema in the superior aspect of the L3 vertebral body
MR 3/16 – Fluid in anterior L2-L3 disc space. Marrow edema and post-gadolinium blush in L3 and to a lesser extent inferior L2 vertebral bodies

CR 3/6 – Normal

CR 5/1 – Progressive loss of disc space and endplate collapse


The classic presentation of discitis is back pain and refusal to walk. While considered infectious, a causative organism is isolated in only 1/3 of patients. Typically, patients are male, about 3 years of age, and have a history of previous trauma. Spinal osteomyelitis has similar symptoms to disci tis although more severe and accompanied by fever. It is usually related to hematogenous spread of S. aureus or gram negative bacteria. Discitis is often found in the lumbar region, L3-L4 and L4-L5. Vertebral osteomyelitis presents in older children, about 8 years of age, has more protracted course of disease and can occur anywhere in the spinal column. Spinal osteomyelitis can be catastrophic in neonates and immunocompromised. Symptoms for both entities are usually present for several weeks before radiographic findings are evident; therefore if clinically suspected, MR should be employed early in the clinical course. Complications of osteomyelitis-discitis include kyphosis, poor longitudinal growth and vertebral fusion.
