Lumbar vertebral osteomyelitis (sans discitis)
Updates to Study Attributes
Minimal generalized reduction in T1 signal in the L4 vertebral body with subtle increased T2 signal on STIR but a heretrogeneous enhancement pattern following IV gadolinium. Small epidural soft tissue mass behind the body of L4 producing marked thecal compression with bilateral psoas inflammatory swelling and locules of fluid (rim enhancing-enhancing) especially on the left indicative of abscess. NotNote endplates (L3/4 abdand L4/5) are intact and the discs show no enhancement or fluid as usually seen in discitis. Pus was drained from the psoas muscles at surgery.
Updates to Case Attributes
This is an unusual case of systemic Staphylococcus aureus infection in a diabetic. Rather than originating in the disc or endplates (spondylodiscitis), infection is located centrally in the vertebral body as osetomyelitis and has spreadosteomyelitis, spreading bilaterally into the posaspsoas muscles and posteriorly into the epidural space. This case highlights the sensitivity of MRI with IV Gad and the insensitivity of CT scanning for the diagnosis of spinal infection.
