case_images: Computed tomography of the neck with contrast (Figure 1) revealed a large lobulated partially rim-enhancing hypodense lesion size (5.3 x 10 x 15.8 cm) with internal septation involving the retropharyngeal space, orohypopharynx, larynx, and left lobe of the thyroid gland.

case_images: However, PTC was found in the pathology of the necrotic tissue and one left cervical lymph node (Figure 2).
case_images: Ultrasound of the thyroid gland showing (a) a large heterogenic hypoechoic mass occupying the entire left thyroid lobe with no hypervascularity and (b) an enlarged left cervical lymph node with cystic necrosis.
