Nomenclature System for Parathyroid Gland Location

Nomenclature system for parathyroid location

 

  • Figure 1 A and B: Nomenclature system for parathyroid location.

    • type A gland is a “normal” superior gland in proximity to the posterior surface of the thyroid parenchyma:

      • It may be compressed within the capsule of the thyroid.

    • A type B gland is a superior parathyroid gland that has fallen posteriorly into the tracheoesophageal groove:

      • There is minimal or no contact between the gland and the posterior surface of the thyroid tissue.

    • A type C gland is a superior gland that has fallen posteriorly into the tracheoesophageal groove and lies at the level of or below the inferior pole of the thyroid.

    • The type D gland lies in the mid region of the posterior surface of the thyroid parenchyma, near the junction of the RLN and the inferior thyroid artery:

      • The type D gland may be either a superior or inferior gland, depending on its exact relationship to the nerve, which generally cannot be determined on imaging.

    • The type E gland is an inferior gland in close proximity to the inferior pole of the thyroid parenchyma anterior to the trachea.

    • The type F gland is an inferior gland that has descended into the thyrothymic ligament or superior thymus:

      • It may appear to be “ectopic” or within the mediastinum.

    • type G gland is a rare intrathyroidal parathyroid gland.
