“…Previously, slightly low signal intensity on T1weighted and high signal intensity on both T2weighted and STIR sequences were reported in postoperative infections of disc, vertebrae and paravertebral soft tissues 9 . After contrast administration, heterogenous pattern of enhancement was reported 9 . A study comparing degenerative end plate changes with infectious one by diffusion weighted MR imaging showed hypointensity at the Modic type 1 disorders controversially high signal intensity of infectious spondylodiscitis on diffusion weighted MR images 10 .…”

Post operative disc space infection is relatively uncommon. The incidence of postoperative disc space infection is 0.21 %-3.6 % in association with all vertebral surgical procedures. Surgery causes a variety of neuroendocrine and metabolic responses which generally results in immunosupression. Clinical results of immunosupression include delayed wound healing and septic complications. In this article, we report magnetic resonance imaging findings of a case with spondylodiscitis and spinal epidural abscess in which the imaging findings were apparent before the infection and inflammation related laboratory findings laboratory findings become positive. She has a history of surgery due to lumbar herniated disc a month. She was complaining of back and left leg pain. We performed contrast-enhanced MR imaging. MR imaging showed post operative changes at level L5 and S1. There was contrast enhancement at the level of the surgical gap in the posterior paravertebral muscles. MR imaging may help to differentiate postoperative spondylodiscitis and epidural abscess from early postoperative changes even before the laboratory tests appearing positive. In our case, surgery induced immunosupression may cause the infection and inflammation related laboratory findings being within normal limits at the beginning.

Spinal trauma is a devastating event with a high morbidity and mortality. The rationale of imaging is to diagnose the traumatic abnormalities and characterize the type of injury, to estimate the severity of the lesions, to evaluate the potential spinal instability. In case of spinal instability, the goals of operative treatment are decompression of the spinal cord canal and stabilization of the disrupted vertebral column. Particularly, diagnostic imaging, mainly by CT and MR, has a main role in the posttreatment evaluation. The neuroradiological evaluation of the postoperative spine requires a general knowledge of the surgical approach to each spinal region and of the normal temporal evolution of expected postoperative changes. The neuroradiologist should evaluate the devices implanted, their related complications and promptly alert the surgeon of acute complications, mainly vascular and infective. During the follow-up, it is mandatory to know and search chronic complications as pseudomeningocele, accelerated degenerative disease, arachnoiditis, peridural fibrosis. Knowledge of specific complications relating to each surgical approach will assist the neuroradiologist in interpretation of postoperative images.

“…20,21 These images must, however, be interpreted with caution because it can be difficult to distinguish normal postoperative changes from early postoperative infection. 22 In cases of discitis or osteomyelitis, on T1-weighted sequences, infection is observed as an area of low-signal intensity in the disc space or marrow of the vertebral body. The endplates lose their definition and appear hypointense compared with the bone marrow.…”
