This sagital,T1-weighted MR image of the lumbar spine shows marked loss of normal signal (looks darker than normal) of L5 and S1 vertebral bodies,with increased surrounding soft tissue extending into the ventral epidural space and compressing the thecal sac. The epidural component is an abscess/phlegmon. This represents discitis (disc space infection) and vertebral osteomyelitis (bone infection). There are often blood-borne organisms deposited in these locations secondary to bacteraemia (infections in the blood stream) | |
