title: MR images mimic disc after discectomy.
abstract: MRI of a 30-year-old woman 1 year after discectomy showed a residual disc-like tissue. The observation was initially confusing, but a close comparison of pre- and post-operative images suggested that the inferior wall of the anterior joint capsule had migrated superiorly after the removal of the disc and mimicked a residual disc on the follow-up MR images.
