case_images: Otolaryngology examination revealed swelling, redness, and tenderness of approximately 7cm, especially in the area corresponding to the thyroid region (Figure 1).
case_images: Neck ultrasound of the patient. (A) Axial ultrasound image of thyroid right lobe and isthmus of the patient. The right lobe appears to be normal (B) Axial ultrasound image of the left lobe of the patient. A heterogeneous lesion composed of septated cystic component, intact thyroid parenchyma is not present in the left lobe. Compartments in cystic echogenicity are observed in the left anterior region of the neck, on skin, subcutaneous tissue, and thyroid lobes. RL: right lobe; is: isthmus; T: trachea; LB: left lobe.

case_images: In the left anterior neck region, there were compartments with cystic echogenicity on the skin, subcutaneous tissue and thyroid region, while the right thyroid gland parenchyma was normal (Figure 2).
case_images: Axial (A), sagittal (B) and coronal (C) non-contrast computed tomography images of the patient. There is a heterogeneous, hypodense lesion located on the left lobe through the isthmus level, and the necrotic-fluid density areas extending from the midline to the right lobe (white arrow). An: anterior; R: right side.

case_images: Neck computed tomography with no contrast enhancement revealed a heterogeneous, hypodense lesion, containing some areas of necrotic-liquid density, 65x60x65mm in size, located on the left lobe, along the isthmus level and extending from the midline to the right lobe (Figure 3).
