A rare case of lateral aberrant thyroid tissue was found as the only thyroid tissue in a woman, leading to hypothyroidism after removal. Isotopic scanning is recommended for neck masses to identify ectopic thyroid tissue before treatment.

Area of Science:

  • Endocrinology
  • Surgical Anatomy
  • Thyroidology

Background:

  • Thyroid gland development typically occurs in the midline of the neck.
  • Lateral aberrant thyroid tissue is an uncommon finding.
  • Congenital absence of the thyroid gland in the normal location is rare.

Observation:

  • A 28-year-old woman presented with a neck mass in the right carotid triangle.
  • This mass was identified as the entirety of her thyroid tissue.
  • Surgical resection of the mass resulted in hypothyroidism.

Findings:

  • The patient had lateral aberrant thyroid tissue as her sole thyroid gland.
  • The absence of thyroid tissue in the usual anatomical location was confirmed.
  • Post-surgical hypothyroidism indicated the functional significance of the aberrant tissue.

Implications:

  • This case highlights the possibility of ectopic thyroid tissue presenting as a lateral neck mass.
  • It suggests a potential developmental anomaly where thyroid tissue migrates laterally.
  • Pre-operative isotopic scanning of the thyroid is advised for midline or low lateral neck masses to prevent inadvertent removal of all thyroid tissue and subsequent hypothyroidism.
