Herniated Intervertebral Disc l: Introduction01:29

Herniated Intervertebral Disc l: Introduction

38
Intervertebral disc herniation refers to the displacement of the nucleus pulposus (the gel-like inner core of the disc) through a tear or weakened area in the annulus fibrosus (the outer fibrous ring). The displaced disc material extends beyond the normal boundaries of the disc space and may compress or irritate nearby spinal nerve roots or, less commonly, the spinal cord.Etiology and Risk FactorsHerniation commonly results from degeneration, in which aging reduces disc hydration and...

Degenerative Disc Disease ll: Pathophysiology

28
The symptoms of degenerative disc disease arise from a combination of mechanical compression, vascular compromise, and biochemical inflammation, which together disrupt nerve function and produce pain.Mechanical CompressionDisc degeneration reduces height and elasticity, predisposing to herniation of the nucleus pulposus, a major cause of radicular pain. Herniations may be protrusion (bulging with intact annulus), extrusion (nucleus extends beyond disc but remains connected), or sequestration...

Area of Science:

  • Neurosurgery
  • Orthopedic Oncology
  • Radiology

Background:

  • A 47-year-old woman presented with acute onset of severe low back pain (lumbago) and left leg radiculopathy.
  • Symptoms included incapacitating pain, significantly impacting her ability to walk and sleep.

Purpose of the Study:

  • To report a case of spinal extradural chondroma presenting as acute radiculopathy.
  • To highlight the diagnostic features and successful surgical management of this rare spinal tumor.

Main Methods:

  • Clinical presentation and neurological examination findings were documented.
  • Magnetic Resonance Imaging (MRI) was utilized to characterize the spinal mass.
  • Surgical excision via left partial laminectomy was performed.
  • Histopathological examination confirmed the diagnosis of chondroma.

Main Results:

  • MRI revealed a contrast-enhancing spinal extradural mass at the L2-3 level with specific signal intensities on T1-weighted and T2-weighted images.
  • The patient experienced complete resolution of radiating leg pain following surgical removal.
  • Histopathology confirmed the mass as a chondroma, characterized by mature hyaline cartilage and benign-appearing cells.

Conclusions:

  • Spinal extradural chondroma is a rare cause of acute radiculopathy.
  • Early diagnosis via MRI and prompt surgical intervention can lead to excellent outcomes.
  • Chondroma should be considered in the differential diagnosis of spinal extradural masses causing nerve root compression.
