Aberrant thyroid - case 250

Nodular goiter

Next

Clinical data: A 49-year-old woman was referred for evaluation of a neck mass which was discovered by the patient several years ago.

Palpation: a not firm lesion above the usual location of the thyroid in the middle of the neck.

Laboratory test: TSH 0.77 mIU/L.

Ultrasonography. The thyroid was echonormal and had several nodules in both lobes. The mass in the neck proved to be the pyramidal lobe because it was connected to other parts of the thyroid with a thin stalk. The pyramidal lobe was composed of a nodule with different echogenicities.

Cytology was performed form the lesion in the pyramidal lobe and resulted in benign colloid goiter.

Comment. By definition, we can only speak of aberrant tissue if it is not connected to the thyroid gland in its normal position. In this case, a thin handle can be identified that connects the neck mass to the thyroid gland. It is worth noting that this thin handle is often not visible, even because it is absorbed.
