Introduction: Intradural disc herniation is rare pathological condition. This case report was an experience of an intradural disc hernia encountered during revision MED (Re-MED) for recurrent of disc herniation.
Case report: A 48-year-old woman with a chief complaint of right leg pain. L5/S right disk hernia was recognized and MED was performed. Two years after the operation, right lower extremity pain reappeared. An MRI scan showed a recurrent disk herniation at the same site. Re-MED was performed. However, the expected disk herniation mass was not confirmed. The herniation mass was confirmed intradural. An incision was made in dura mater and the herniation mass was removed. The JOA score after Re-MED improved.
Conclusion: Re-MED is a useful technique for recurrent of disc herniation. However, considering the possibility of intradural disc herniation during Re-MED, appropriate preoperative preparation is necessary.
