Insights

Vertebral osteomyelitis can mimic tumors, especially when it affects only the vertebral body without disc involvement. This review highlights key MRI findings for diagnosing these challenging cases.

Area of Science:

  • Radiology
  • Infectious Diseases
  • Rheumatology

Background:

  • Vertebral osteomyelitis commonly involves intervertebral discs and adjacent vertebral bodies, often due to pyogenic or granulomatous infections.
  • Non-infective causes like chronic recurrent multifocal osteomyelitis (CRMO) and SAPHO syndrome can also affect the spine.
  • These conditions may present solely within the vertebral body, mimicking neoplastic disease with edema, sclerosis, or collapse.

Purpose of the Study:

  • To illustrate the imaging features of vertebral osteomyelitis specifically when there is no disc involvement.
  • To emphasize the role of magnetic resonance imaging (MRI) in diagnosing vertebral osteomyelitis without disc compromise.

Main Methods:

  • Review of imaging findings in cases of vertebral osteomyelitis.
  • Focus on magnetic resonance imaging (MRI) characteristics.
  • Comparison with non-infective mimics and neoplastic conditions.

Main Results:

  • Vertebral osteomyelitis without disc involvement presents with varied patterns of vertebral marrow edema and sclerosis.
  • Destructive vertebral body lesions and pathological collapse are observed.
  • Imaging findings can closely resemble primary or metastatic neoplastic disease.

Conclusions:

  • Recognizing vertebral osteomyelitis without disc involvement is crucial for accurate diagnosis.
  • MRI is essential for differentiating infectious from neoplastic causes.
  • Understanding these imaging features aids in appropriate patient management.

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...

Degenerative Disc Disease I: Introduction

Degenerative disc disease is a chronic condition in which intervertebral discs gradually lose structure and function. It is not infectious or autoimmune; rather, it results from age-related biochemical and mechanical changes, influenced by genetic, metabolic, and environmental factors.Structure and Function of DiscsThe spine contains 23 intervertebral discs that absorb load, distribute forces, maintain spacing, and allow flexibility. Each disc consists of a nucleus pulposus, a gel-like core...

Degenerative Disc Disease ll: Pathophysiology

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...
