Extensive Intravascular Thyroid Vein Extension in Follicular Thyroid Carcinoma: Ultrasound Clues

The identification of intravascular tumor thrombi in thyroid at the time of fine-needle aspiration is important as it is, by definition, a diagnosis of malignancy. While ultrasound findings of tumor thrombi in the great veins of the neck have been well described, thrombi in the thyroid veins can be very difficult to detect and have been seldom reported. This case study, with extensive thyroid vein tumor involvement, provides clues for raising the possibility of a malignant process at the time of ultrasound-guided FNA, by correlating the pathology findings with the ultrasound images.
