| description | Intervertebral disc herniation is frequently encountered in radiological practice. Sequestered disc
herniation occurs when the disc material undergoes degeneration and completely loses continuity
with the parent nucleus pulposus. Sequestered discs can reside within and outside the spinal canal,
exerting a mass effect on adjacent structures, compressing nerve pathways, and eliciting a range of
clinical symptoms. In particular, sequestered discs within the dura cannot be identified without durotomy.
Therefore, precise preoperative localization is crucial for surgical planning. On MRI, the signal
intensity of the sequestered disc may vary due to independent degeneration processes. Additionally,
most sequestered disc fragments show varying degrees of peripheral enhancement depending on
the degree of angiogenesis and granulation around the isolated tissue. In this article, we review various
imaging findings and the location of the sequestered disc to provide patients with an accurate diagnosis
and appropriate treatment direction. |
