The boundary was not clear from the surrounding and could move up and down with the swallowing movement. The trachea shifts slightly to the left. There were no enlarged lymph nodes around. During the operation, the right lobe was obviously swollen, hard and the surface was not smooth, and there was slight adhesion with the surrounding tissue. Only right thyroidectomy and left lobe were performed.
