Discrete lesion or nodule in Hashimoto's thyroiditis - case 23 (1401) (ultrasonographic picture 2)

Right lobe, longitudinal view. The lesion in the dorsal part has echonormal areas and partly blurred borders. It is doubtful whether this lesion is a nodule in pathological sense or not. The pattern resembles that of an echonormal, intact part of the thyroid which is infiltrated by the underlying thyroiditis.
