Herniated Intervertebral Disc l: Introduction01:29

Herniated Intervertebral Disc l: Introduction

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...
Brain Abscess l: Introduction01:26

Brain Abscess l: Introduction

A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...

Summary

This case report details a rare symptomatic lumbosacral interdural arachnoid cyst causing leg pain. Surgical findings suggest a congenital origin for this unusual spinal cyst.

Area of Science:

  • Neurosurgery
  • Spinal Imaging
  • Congenital Malformations

Background:

  • Interdural arachnoid cysts are rare spinal malformations.
  • Symptomatic presentation often involves neurological deficits.

Observation:

  • A 72-year-old man presented with acute right buttock and lower extremity pain and weakness.
  • Imaging revealed an isolated lumbosacral interdural arachnoid cyst.
  • Surgery confirmed a cyst within a double-layered dura, separate from the arachnoid membrane.

Findings:

  • The cyst contained cerebrospinal fluid and evidence of recent hemorrhage.
  • Surgical removal was straightforward.
  • The cyst's origin remained unclear but was suspected to be congenital.

Implications:

  • This case highlights the importance of considering rare spinal pathologies in patients with neurological symptoms.
  • Understanding the congenital etiology of such cysts is crucial for diagnosis and management.
  • Further research into the pathogenesis of interdural arachnoid cysts is warranted.
