Summary

Magnetic resonance (MR) imaging effectively evaluates granulomatous spinal infections, predicting complications and infection types. Contrast-enhanced MR imaging is crucial for identifying abscesses and spread, aiding diagnosis and follow-up.

Area of Science:

  • Radiology
  • Infectious Diseases
  • Spinal Imaging

Background:

  • Granulomatous spinal infections pose diagnostic challenges.
  • Accurate assessment is vital for effective treatment and patient outcomes.

Purpose of the Study:

  • To evaluate the utility of magnetic resonance (MR) imaging in diagnosing and managing granulomatous spinal infections.
  • To correlate MR imaging findings with clinical, microbiologic, and surgical data.

Main Methods:

  • Retrospective analysis of 81 patients with confirmed granulomatous spinal infection.
  • Inclusion of contrast-enhanced MR imaging (gadolinium diethylenetriaminepentaacetic acid) in 27 patients.
  • Correlation of blinded MR interpretations with clinical, microbiologic, and surgical findings.

Main Results:

  • MR imaging accurately predicted neurologic complications (93%) and infection type (94%).
  • Contrast-enhanced studies identified vertebral abscesses, meningeal involvement, and paraspinal abscesses, particularly in tuberculous spondylitis.
  • T1-weighted signal intensity suggested healing and correlated with symptoms.

Conclusions:

  • MR imaging is a valuable tool for initial assessment and post-therapy follow-up of granulomatous spinal infections.
  • It aids in predicting complications and identifying specific infection characteristics.
  • Contrast-enhanced MR imaging enhances the detection of key pathological features.
