Definition: Calcium deposits in the thyroid cartilage, visible on panoramic and lateral cephalometric radiographs.
Radiographic Features:
- Location:
- Inferior to hyoid bone
- Anterior to cervical vertebrae
- Edge:
- Well-defined
- Smooth or irregular outline
- Shape:
- Matches lateral view of thyroid cartilage
- Often described as shield-shaped or triangular
- Internal:
- Radiopaque border with radiolucent center
- May appear as mixed radiopaque/radiolucent
- Number: Single (only one thyroid cartilage)
Key Diagnostic Signs:
- Characteristic shape and location in neck region
- Partially calcified appearance
Clinical Significance:
- Normal physiological process, typically age-related
- More common in males and older individuals
- Not pathological, but can be mistaken for other calcifications
- Important to recognize to avoid misdiagnosis
Note: Recognizing thyroid cartilage calcification is crucial for differentiating it from pathological calcifications in the neck region. The extent and pattern of calcification can vary among individuals and with age. This finding should not be confused with thyroid gland calcifications, which may indicate pathology.
