[Disk highlighting after injection in MRI. Macroscopy and histology of 25 postoperative recurrences].
400 cases of failed back syndrome were examined with MRI in a prospective study (SE w Rho and T2, SE wT1 before and after injection of paramagnetic contrast agent in axial and sagittal planes). After second time surgery, 70 cases of herniated disks were found. 25 herniated disks were studied in microscopy and results correlated with enhanced herniated disks. Authors describe 4 types of enhancement: veinous plexus (5/24), inflammatory or granulomatous tissue (12/24), degenerative disc with fibrosis (5/24) and osteophytosis (2/24). The criterions of each pattern are described.
