Background & Importance: Disc herniation is defined as the prolapsed of material disc into the spinal canal. If the disc fragment is free in spinal canal, it is called sequestration disc fragment. Occasionally, alteration in sequestration disc fragment makes the diagnosis of the disc herniation, challenging. Case Presentation: We reviewed a rare case of the cervical sequestrated disc...

Case Presentation: We reviewed a rare case of the cervical sequestrated disc herniation mimicking a spinal canal extradural abscess. The 55-year-old man presented cervical axial and radicular pain. Cervical spine MRI showed an extra-axial longitudinal mass behind C5 and C6 vertebral body association with anterior compression on cord. In T2 images of lesion, the signal intensity varied from isoi...

STUDY DESIGN A retrospective study was undertaken to delineate the characteristics of non-traumatic sequestrated epidurally migrated cervical disc prolapse. PURPOSE To present first case series of eight such cases diagnosed preoperatively and to discuss their magnetic resonance imaging (MRI) characteristics and their management. OVERVIEW OF LITERATURE Non-traumatic spontaneous migration of ...

A 56-year-old man presented with a rare case of a voluminous herniated disc fragment mimicking an intraspinal extradural tumor on magnetic resonance (MR) imaging. He had experienced low back pain and sciatica in his right leg for 12 months, which exacerbated suddenly 4 days before admission accompanied by right quadriceps muscle weakness. MR imaging with gadolinium demonstrated a tumor-like lon...

Background and Importance: Disk sequestration can be defined as a herniated disk with perforation of the fibrous ring (or outermost annulus fibrosus) and posterior longitudinal ligament with migration of the disk fragment to the epidural space. Even after the introduction of high-resolution magnetic resonance imaging (MRI), it is still frequently misinterpreted as neoplastic masses. U...

OBJECTIVE This retrospective study was undertaken to evaluate the efficacy of combined microscopic fragmentectomy and intraoperative nucleoplasty for sequestrated lumbar disc herniation. METHODS Twenty-four patients with magnetic resonance imaging proven sequestrated lumbar disc herniation with small annular leak treated by microscopic fragmentectomy and nucleoplasty were included. Patients w...

Objective is to describe a safe and effective percutaneous endoscopic approach for removal of highly migrated and sequestrated disc herniations of the upper lumbar spine and to report the results, surgical indications, and technical considerations of the new technique. Eleven patients who had highly migrated and sequestrated disc herniations in the upper lumbar were included in this study. A re...
