Ultrasonographic (US) examination of neck, the solitary mass with multipl areas of necrosis and cystic parts (thin arrow) and the tumour thrombus of jugular vein (thick arrow) the invasion region of tumour to the jugular vein (arrow head).

Ultrasonographic (US) examination revealed a 5.5x5.5 cm solitary mass with multiple areas of necrosis and cystic parts arising from the operated area, extending and invading the left jugular vein wall (Figure 1) displacing the left carotid artery posteriorly and laterally.
Color Doppler ultrasound of neck; (A) the longitudinal image of the left internal jugular vein (IJV) shows the hyperechoic filling defect and vascularization of tumour thrombus (thick arrow). (B) the transvers image of the vascularization of thyroid mass (thin arrow) and the invasion region (arrow head).

Color Doppler ultrasound revealed that the left internal jugular vein (IJV) was partially (approximately 80%) blocked with a tumor thrombus until the innominate vein (Figure 2), and the left common carotid artery was externally compressed by the mass.
Transvers T2 weighted image of the neck shows a heterogeneous high signal intensity mass (thin arrow) which compresses and displaces the trachea to the right and similar signal intensity of the tumour thrombus (thick arrow) in the IJV and periferally luminal signal void area which shows the partially blood flow.

Magnetic Resonance Imaging (MRI) and Computed Tomography (CT) confirmed the angioinvasive solitary mass. MRI of the neck showed a heterogeneously-enhancing mass with a low signal intensity on T1-weighted images and a high signal intensity on T2-weighted images arising from the operated area, compressing and displacing the trachea to the right and invading the left IJV (Figure 3).
Contrast enhanced CT scan of neck, sagittal (A) and transvers (B) images shows large ill defined heterogenous mass (thin arrow) and the extention of mass laterally into the IJV (arrow head) by causing filling defect (thick arrow).

A CT scan of the neck was performed and showed a large ill-defined heterogenous mass extending laterally to IJV and causing a filling defect (Figure 4).
