Ultrasonography revealed a linear hyperechoic shadow from the upper inner side to the lower outer side of the left thyroid lobe, which was adjacent to the internal jugular vein, and no obvious rupture of the internal jugular vein was found (Figure 1).

Computed tomography (CT) revealed that the left lobe of the thyroid had an oblique sloping high-density shadow from top to bottom, approximately 2.5 cm in length, with the tip reaching the outer edge of the thyroid gland and 2 mm from the left internal jugular vein (Figure 2).

Under gastroscopy, a quasi-circular wound with a maximal length of approximately 1 cm on the epiglottic mucosa was found, which was considered to be a postoperative wound caused by epiglottic cyst resection (Figure 4A). Furthermore, no evident ulceration or injury was found in the esophageal mucosa (Figure 4B).
