case_images: Contrast-enhanced CT image of head and neck, demonstrating thyroid enlargement and asymmetry. After the administration of contrast, the right lobe contained more hypodense areas without enhancement compared to the left lobe, as indicated by the arrows. There was no extravasation of the contrast medium. These findings are suspicious of contusion or laceration, though the possibility of autoimmune thyroiditis could not be excluded.

case_images: Computed tomography (CT) scanning of the head and neck was performed, showing an enlarged and inhomogeneous thyroid gland and a fractured mandible (see Figure 1).
case_images: Thyroid ultrasonography of the patient demonstrating thyroid enlargement and inhomogeneity. The size of the left lobe was 1.5 x 1.6 x 2.8 cm, and the size of the right lobe was 1.7 x 1.5 x 3.5 cm. Anterior from both thyroid lobes was fluid accumulation.

case_images: Subsequently, contrast-enhanced CT scanning and ultrasonography of the neck showed enlargement and asymmetry of the thyroid gland, with more hypodense areas in the right lobe, suspicious of contusion or laceration, though the possibility of autoimmune thyroiditis could not be excluded (see Figure 2).
