Magnetic resonance imaging follow-up by STIR (upper line) and gadolinium-enhanced fat-suppressed T1-weighted (lower line) sagittal images obtained 24 days after surgery (a) and one month (b), three months (c), and seven months (d) later. Besides complete removal and absence of relapse of the epidural abscess, a clearcut reduction of gadolinium-enhancing reactive changes is evident. Note also the progressive development of kyphosis with fulcrum at L1–L2 level, together with increase of lumbar lordosis.
