Unilateral Thyroid Agenesis Curiosity or Predictor of Future Pathology

Abstract

Unilateral thyroid agenesis (thyroid hemiagenesis) is a rare disorder with less than 300 cases currently in the world literature. The current clinical importance of this condition lies in the possibility that such patients may be at an increased risk for a wide range of future pathology in the contralateral lobe. If this indeed proves to be the case in future, these patients need to be identified. A case of incidentally discovered unilateral thyroid agenesis is presented and the clinical importance discussed.
