Herniated Lumbar Disk Diskectomy
Pathological Postoperative Scar

• Patient with persisting right low back pain in L5-S1 herniated disk
treated by diskectomy and laminectomy
• Early MR postoperative follow-up

Fig. 1 a–c.SET1(a) and axial CE fat sat (b–c). Without fat sat and Gd administration it is possible only to
hypothesize the presence of S1 right periradicular scar because epidural material does not compress but surrounds the
dural sack (a). (b) CE of scar surrounding edematous nerve root. With respect to recurrent hernia, the nerve root is
appreciable along its course in axial sections (b–c)

Case 7 - Herniated Lumbar Disk. Diskectomy 55
Postoperative Follow-Up After 1 Month
Fig. 2 a–g. CE fat sat SE T1 sagittal and axial sections. Exuberant granulation tissue characterized by intense CE, in
the right retrovertebral space at L3–L4. a–g. This tissue extends over lamino-flavectomy in the right foramen, close to
L3 nerve root, thickened by flogosis (arrow)

Postoperative Follow-Up After 3 Months
Fig. 3 a–g. CE fat sat SE T1 sagittal and axial sections. Granulation tissue, even if characterized by high CE, is
mildly reduced. Right L3 nerve root is thickened and surrounded by pathological tissue (arrow)
