Overview

Parathyroid adenoma may be classified according to location into 7 subtypes from type A gland to type G gland.

Classification

Parathyroid adenoma may be classified according to location into 7 subtypes: [1][1][2][3]

Type Location
Type A
  • Adherent to the posterior thyroid parenchyma
  • Expected location of a normal gland
  • Almost attached
  • Almost intracapsular
Type B
  • Back behind the thyroid parenchyma
  • Exophytic to the thyroid parenchyma
  • Lies in the tracheoesophageal groove
  • B+ gland: An undescended gland high in the neck near the carotid bifurcation or mandible
Type C
  • Could be mistaken for the esophagus when palpated
  • Caudal to the thyroid parenchyma, in the tracheoesophageal groove
  • More inferior than a type B gland on lateral views
  • Situated at the level of the inferior pole of the thyroid or inferior to the inferior pole of the thyroid (closer to the clavicle)
Type D
  • Dissection is difficult as the gland is dangerously close to the recurrent laryngeal nerve
Type E
  • The most externally located gland
  • Easy to resect
Type F
  • Fallen into the thyrothymic ligament
  • May be referred as "ectopic"
  • Can be usually retrieved with delivery of the superior portion of the thymus
Type G
  • Got caught in thyroid tissue
  • Gated into the thyroid parenchyma
  • A true intra intrathyroidal gland is rare
