Ultrasound and CT of the thyroid gland and neck. (A, B) Multiple hypoechoic nodules were identified in the right lobe of the thyroid gland, some of which were partially fused, forming a mass with a maximum dimension of approximately 38*21mm. The nodules exhibited irregular morphology and were associated with abundant blood flow signals. (C) Multiple enlarged lymph nodes were detected in the right cervical region, the largest of which was about 42*13mm and contained abundant blood flow signals. (D) CT shows that the right lobe of the thyroid gland exhibited enlargement, accompanied by the presence of a slightly hypodense mass measuring approximately 4.3*4.9 cm. The surrounding fat interstitial space appeared blurred, and the lesion showed indistinct demarcation from the adjacent trachea and esophagus, resulting in leftward displacement of the trachea.
