From the case:
Dorsal epidural disc migration

An oval-shaped posterior epidural lesion at the L3/4 level. The signal intensity is similar to the nuclear disc in all sequences and there is peripheral enhancement. There is a posterior annular tear associated.
Severe thecal sac compression, with loss of CSF signal.
Findings are consistent with dorsal epidural disc migration.
From the case:
Dorsal epidural disc migration

Surgical specimen.
Case Discussion
The patient underwent laminectomy and resection of the disc fragment. Dorsal epidural disc migration is rare and it has to be considered when there is a posterior epidural mass. Peripheral enhancement can be seen.
