"White knight" nodule

The "white knight" nodule is regarded as a benign lesion of the thyroid gland ¹.

Pathology

Follicular cells, Hurthle cells, numerous small and large lymphocytes and colloid are seen on fine needle aspiration cytology of white knight nodules, which is consistent with Hashimoto thyroiditis ^2,3.

Radiographic features

Ultrasound

Best identified in ultrasound imaging as a well-defined, homogenously hyperechoic nodule without internal vascularity, cystic areas or calcifications ^1-3.

The white knight nodule is not considered in ACR TI-RADS classification because of the inconsistency of pattern recognition and debatable correlation with the risk of thyroid disease ⁴.
