Summary
A rare case of aberrant cervical thymic tissue in a child mimicked thyroid enlargement. Ultrasonography is key for diagnosing this uncommon cause of paediatric neck masses.
Area of Science:
- Pediatric Endocrinology
- Head and Neck Surgery
- Diagnostic Imaging
Background:
- Aberrant cervical thymic tissue is a rare congenital anomaly.
- It can present as a neck mass in children, often mimicking other conditions.
- Accurate diagnosis is crucial to avoid unnecessary interventions.
Observation:
- A 9-year-old female presented with a suprasternal neck mass.
- The mass appeared to be an enlarged thyroid gland on initial examination.
- Ultrasonography was performed for diagnostic evaluation.
Findings:
- The ultrasonography revealed suprasternal extension of the thymus, not thyroid enlargement.
- This confirmed the diagnosis of aberrant cervical thymic tissue.
- The imaging successfully differentiated the thymic tissue from the thyroid gland.
Implications:
- Awareness of aberrant cervical thymic tissue is essential for pediatricians and surgeons.
- This diagnosis can prevent patient anxiety and avoid inappropriate investigations or surgical procedures.
- Ultrasonography is a valuable, non-invasive tool for diagnosing neck masses in children.
