Thyroid cartilage at the suprasternal notch with low situated thyroid gland

Area of Science:

• Anatomy
• Embryology
• Congenital Anomalies

Background:

• Thyroid cartilage and gland anatomy are crucial for airway and swallowing functions.
• Congenital anomalies of the upper airway and neck structures are uncommon but can significantly impact patient health.

Observation:

• A unique case presented a thyroid cartilage and thyroid gland forming a suprasternal notch lump.
• The patient exhibited a low-positioned hyoid bone and a pharyngo-oesophageal junction anomaly.
• Intrathoracic cricoid cartilage with absence of cervical trachea was a notable feature.

Findings:

• This combination of congenital anomalies, including a suprasternal thyroid cartilage/gland lump and absent cervical trachea, appears to be a novel finding in medical literature.
• The study suggests a potential pathogenesis for this complex malformation.

Implications:

• Understanding the pathogenesis of such rare anomalies is vital for accurate diagnosis.
• The surgical implications are significant, requiring specialized approaches for management.
• This case highlights the importance of thorough diagnostic evaluation for complex congenital neck abnormalities.
