Lumbar Intervertebral Disc and Discovertebral Segment. Part 2: An Imaging Review of Pathologic Conditions With...

Area of Science:

• Spinal Imaging
• Radiology
• Pathology

Background:

• The lumbar intervertebral disc is a complex structure susceptible to various pathologies.
• Conditions include degenerative changes, trauma, infections, inflammation, metabolic diseases, and tumors.
• Atypical presentations can mimic asymptomatic degenerative changes, complicating diagnosis.

Purpose of the Study:

• To review and illustrate a spectrum of abnormalities affecting the discovertebral segment.
• To provide detailed analysis using postmortem material with anatomic-imaging correlation.
• To enhance radiologists' ability to diagnose diverse conditions of the intervertebral disc.

Main Methods:

• Review of a range of abnormalities affecting the discovertebral segment.
• Detailed analysis of postmortem specimens.
• Correlation of imaging findings with anatomic features.

Main Results:

• Pathologic processes affecting the lumbar intervertebral disc are diverse.
• Abnormalities can present atypically, mimicking other conditions.
• The discovertebral segment encompasses a wide array of potential diseases.

Conclusions:

• Comprehensive knowledge of intervertebral disc and discovertebral segment abnormalities is crucial.
• Anatomic-imaging correlation aids in differential diagnosis.
• Radiologists can improve diagnostic accuracy for a broad spectrum of diseases.
