Abstract

A 74-year-old female patient suffered unbearable pain and motor weakness that suddenly occurred 3 weeks after lumbar surgery. On magnetic resonance imaging, an unusual lesion was shown as intermediate signal intensity on T2 weighted image indicating neural components which has continuity from thecal sac to the disc space. Revision operation confirmed intradiscal root herniation and entrapment caused by underdiagnoses of suspicious of incidental ventral durotomy during previous surgery. Indirect dural repair with DuraSealTM and Gore-tex® was performed and marked improvement of preoperative pain and weakness were noted following surgery.

Key Words: Nerve entrapment; Herniation; Discectomy; Dura; Injury.
