Summary
Thyroid hemiagenesis, a rare congenital disorder affecting less than 0.1% of patients needing thyroid surgery, involves the underdevelopment of one thyroid lobe. This case highlights the importance of further evaluation for associated surgical risks.
Area of Science:
- Endocrinology
- Surgical Pathology
- Congenital Anomalies
Background:
- Thyroid hemiagenesis is a rare congenital anomaly, accounting for <0.1% of thyroid disorders requiring surgery.
- It typically results from the failure of one thyroid bud to develop, most commonly affecting the left lobe.
Observation:
- A 38-year-old woman presented with preoperatively diagnosed thyroid hemiagenesis.
- The condition was identified and subsequently managed surgically at our clinic.
Findings:
- Scintigraphy revealed a nonfunctional lobe, necessitating further evaluation with ultrasonography.
- Thyroid hemiagenesis can be associated with increased morbidity when coexisting with other surgical anomalies.
Implications:
- This case underscores the importance of thorough preoperative evaluation for rare congenital thyroid anomalies.
- Understanding the potential complications associated with thyroid hemiagenesis is crucial for surgical planning and patient management.
