Annulus fibrosus calcification in the cervical spine: radiologic-pathologic correlation

Area of Science:

• Radiology
• Pathology
• Orthopedics

Background:

• Intervertebral disc calcification is a known condition.
• It can be associated with various underlying pathologies such as arthritis, metabolic disorders, and trauma.
• The annulus fibrosus is the most frequently affected component.

Observation:

• Two young patients presented with calcification in the anterior annulus fibrosus.
• Radiologic-pathologic correlation was performed in an additional case.
• Anterior annulus fibrosus calcification can mimic vertebral body fracture, limbus vertebra, or persistent ring apophysis.

Findings:

• Calcification in the anterior annulus fibrosus was observed in young patients.
• Radiologic and pathologic findings confirmed the nature of this calcification.
• The condition may be a consequence of subclinical or chronic stress on the intervertebral disc.

Implications:

• Understanding this specific type of disc calcification is crucial for accurate diagnosis.
• It highlights the potential for chronic stress to induce structural changes in the intervertebral disc.
• Further research may elucidate the long-term consequences and management of anterior annulus fibrosus calcification.
