Summary
Thyroid hemiagenesis, a rare condition, is often found incidentally. This case highlights its importance in diagnosing thyroid abnormalities.
Area of Science:
- Endocrinology
- Radiology
Background:
- Thyroid hemiagenesis is a congenital anomaly where one lobe of the thyroid gland fails to develop.
- It is typically asymptomatic and discovered incidentally during investigations for other thyroid conditions.
Observation:
- A 25-year-old woman presented with findings suggestive of thyroid hemiagenesis.
- An Iodine-123 thyroid scan revealed a normal right lobe with absent uptake in the left lobe.
- Neck ultrasonography confirmed the unilateral absence of the thyroid lobe.
Findings:
- The diagnostic imaging confirmed thyroid hemiagenesis, characterized by the absence of the left thyroid lobe.
- The remaining right thyroid lobe appeared normal in size and echogenicity.
Implications:
- Thyroid hemiagenesis should be considered in the differential diagnosis of thyroid gland abnormalities.
- This condition underscores the importance of comprehensive evaluation in thyroid imaging.
- Accurate diagnosis is crucial for appropriate patient management and follow-up.
