Abstract:
Recurrent disc herniation and postoperative fibrosis are the main disease entities causing failed back surgery syndrome (FBSS) and magnetic resonance (MR) imaging has become a major diagnostic modality in differentiating the two. To observe the variable entities of FBSS and their MR findings, we retrospectively analyzed 15 MR images in 12 patients. The causes of FBSS were as follows; normal (no organic cause), fibrosis, new or recurrent disc herniation, discitis, osteomyelitis, inflammation at operation site, epidural abscess, arachnoiditis, and hematoma. Except a case of hematoma, gadolinium enhancement scan was necessary and informative in the diagnosis of FBSS and MR imaging only was not enough in the diagnosis of arachnoiditis.
