Summary
This study reports a rare case of a simultaneous thyroglossal duct cyst (TDC) and parathyroid cyst (PC) in a 47-year-old woman. The findings explore the potential correlation between these two congenital anomalies.
Area of Science:
- Congenital anomalies
- Embryology
- Head and neck surgery
Background:
- Thyroglossal duct cysts (TDC) are common congenital anomalies arising from the embryonic thyroglossal duct.
- TDCs typically occur in isolation, with rare associations with other congenital malformations.
- Previous reports document TDC co-occurrence with branchial cleft cysts, thyroid cancer, hematoma, and epidermoid cysts.
Observation:
- A 47-year-old woman presented with a neck tumor.
- Diagnostic imaging, including ultrasound and CT, confirmed a cervical thyroglossal duct cyst and a left parathyroid cyst.
- Surgical resection was performed, and pathology confirmed both diagnoses.
Findings:
- This case presents the first reported instance of a simultaneous thyroglossal duct cyst and parathyroid cyst.
- Post-operative follow-up for 1 year revealed no significant recurrence of either cyst.
Implications:
- This rare co-occurrence prompts further investigation into the potential embryological correlation between TDC and parathyroid cysts.
- Understanding such associations may refine diagnostic and management strategies for complex congenital neck masses.
